    How should you heat your home in the green energy transition? A scenario-based multi-criteria decision-making approach2023Inngår i: Journal of Cleaner Production, ISSN 0959-6526, E-ISSN 1879-1786, Vol. 421, artikkel-id 138398Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The choice of heating system is significant for city planners and building owners alike, and many important areas, such as the well-being of residents, climate change impact and resource efficiency, may influence the choice. Understanding how to balance these areas is crucial for effective decision-making that can contribute to sustainable development and the green energy transition. However, these decisions represent complex problems where disparate knowledge areas must be considered simultaneously. When faced with this type of decisionmaking problem, employing different multi-criteria decision-making methods is common. However, such methods only provide a snapshot of which alternative is preferred and because of this, their results may become obsolete due to changes in the performance of alternatives or the value perceptions of the decision-makers. To overcome this challenge and to improve the longevity and reliability of multi-criteria decision-making results, the authors of this study explored a novel approach to producing semi-dynamic results through scenarios, which were used to consider possible future changes to the alternatives performance and the decision-makers value perceptions. The application of scenarios in the multi-criteria decision-making method enabled nuanced information to be produced on how the performance of different heating alternatives may change under different plausible futures. This approach was demonstrated by applying it to the case of residential heating in Denmark, where results showed that while final rankings varied across both scenarios and ranking methods, solar heating was the preferred alternative, while the oil boiler alternative performed the worst. Overall, this study highlights the importance of considering likely future changes to both the performance of alternatives and the value perceptions of decision-makers when making decisions with long lifetimes and suggests an approach for doing this.

    Fuzzy Ensemble of Multi-Criteria Decision Making Methods for Heating Energy Transition in Danish Households2021Inngår i: Mathematics, E-ISSN 2227-7390, Vol. 9, nr 19, artikkel-id 2420Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    More than 110 countries, including 500 cities worldwide, have set the goal of reaching carbon neutrality. Heating contributes to most of the residential energy consumption and carbon emissions. The green energy transition of fossil-based heating systems is needed to reach the emission goals. However, heating systems vary in energy source, heating technology, equipment location, and these complexities make it challenging for households to compare heating systems and make decisions. Hence, a decision support tool that provides a generalized ranking of individual heating alternatives is proposed for households as decision makers to identify the optimal choice. This paper presents an analysis of 13 heating alternatives and 19 quantitative criteria in technological, environmental, and financial aspects, combines ideal solution-based multi-criteria decision making with 6 weighting methods and 4 normalization methods, and introduces ensemble learning with a fuzzy membership function derived from Cauchy distribution to finalize the ultimate ranking. The robustness of the proposed method is verified by three sensitive analyses from different aspects. Air-to-water heat pump, solar heating and direct district heating are the top three rankings in the final result under Danish national average data. A framework is designed to guide decision makers to apply this ranking guideline with their practical, feasible situations.

    Environmental Impact of an Electric Motor and Drive: Life Cycle Assessment and a study of a Circular Business Model2020Independent thesis Advanced level (degree of Master (Two Years)), 20 poäng / 30 hpOppgave
    Abstract [en]

    Electric motors are one of the biggest consumers of electricity in the world with a consumption of almost 45 % and it is predicted to increase. Since electric motors play an important role today and in the future, it is important that businesses take their responsibility to make them as sustainable as they can possibly be. Today’s product development models are often based on the idea that the customer buys the product and is responsible for the products use phase. This results in the manufacturer focusing on getting a competitive price for the customer by reducing the cost for manufacturing and delivery, which often is negative for the customer. The latter phases, use and end-of-life, are often the greatest contributors of costs and environmental impact. One way for businesses to take their responsibility is to have an environmental focus throughout their products life cycles, i.e., to apply a circular business model. This primarily means to focus on the main principles of circular economy: to reduce, reuse and recycle. ABB is a company in the electric motor and drive industry with ambitious commitments for 2030 which includes to have at least 80 % of their products and solutions covered by a circularity approach and achieve carbon neutrality across their own operations. This Master thesis studies the environmental impact of an ABB synchronous medium voltage motor and drive during their life cycle. This thesis also studies how a circular business model can affect the environmental impact the motor contribute with today.

    Assessing the environmental impact was done with a life cycle perspective in accordance to ISO 14044, using the world’s most used tool for these kinds of analyses, SimaPro. The results of the assessment showed that the total climate impact during the whole life cycle of the motor and drive is 4.38•106 kg CO2 eq. The use phase of the motor and drive was the biggest contributor, with almost 99 % of total climate impact. The electricity used in this phase and the long lifetime of these machines, in this case 20 years, contributes to the great impact. Important environmental impact categories identified from studying the motor and drive during their lifecycles are ionizing radiation, human toxicity (both non-cancer effects and cancer effects) and freshwater ecotoxicity. The results also showed that by only looking at the contribution of the components of the motor, the climate impact is 7.35•104 kg CO2 eq. A total of 43 % of the emissions comes from the stator and 30 % from the rotor. For the drive the total impact is in total 6.83•104 kg CO2 eq. The biggest contributor is the semiconductor, with 50 % of the total impact of the machine followed by the housing with 21 %.

    Answering research question two, regarding the circular business model, was done by interviewing key players at ABB and people with knowledge in the area as well by studying literature. Potential measures for a circular business model were for example increasing the efficiency of the motor, designing for refurbishment and recycling, partnerships and changing the motor application after use. Increased efficiency of the motor was identified as a very impactful measure since it can affect the use phase, which is the biggest contributor of climate impact. The identified measures impact the material and energy flows in different ways, most of them prevent extraction of new raw material. This study can be used for an indication of where the environmental hotspots are for a MV electric motor and drive. It can be concluded that a circular business model could bring benefits on material and energy flows such as reduced energy use in the use phase, decreased use of raw material in production and reduced use of fuel for transportation.

    Learning in focus groups: An analytical dimension for enhancing focus group research2007Inngår i: Qualitative Research, ISSN 1468-7941, E-ISSN 1741-3109, Vol. 7, nr 2, s. 249-267Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The focus group is a research methodology in which a small group of participants gathers to discuss a specified issue under the guidance of a moderator. The discussions are tape-recorded, transcribed and analysed. Notably, the interaction between focus group participants has seldom been evaluated, analysed or discussed in empirical research. We argue that considering the focus group in light of current research into interaction in problem-based learning (PBL) tutorial groups would facilitate the deliberate exploitation of group processes in designing focus groups, staging data collection and analysing and interpreting data. When the analytical focus shifts from mere content analysis to an analysis of what the participants themselves are trying to learn, one can explore not only what the participants are talking about, but also how they are trying to understand and conceptualise the issue under discussion. © 2007 Sage Publications.

    Integrating Requirements Engineering for Different Domains in System Development: Lessons Learnt from Industrial SME Cases2017Inngår i: Procedia CIRP: 9th CIRP IPSS Conference: Circular Perspectives on PSS / [ed] Tim C.

    Abstract [en]

    There is a trending transition for companies from offering products to solutions in order to fulfill better customer needs and to reduce environmental impact by e.g. dematerialization. This solution-based development has an associated integration of intelligent devices that contributes to increasing system complexity. The ability of systems engineering processes, methods and tools to cope with these developments is a critical factor for manufacturing companies today. Still, in many cases it is hard to find adequately trained people and sufficiently integrated development tools for complex solutions, especially in the case of small and medium sized enterprises. Often, the tangible (hardware) part of the solution is primarily developed and the intangible parts (software and services) are added on top. However, key for a successful development is to adapt and integrate all parts according to the requirements set for the solution. Thus, it is essential how requirements are worked with during systems engineering and how they influence the development of the tangible and intangible parts of the solution. The objective of this paper is to study the approach of different industrial use cases for requirements engineering in system development. The aim is to identify how practices from domains like mechanical engineering, software or service engineering can be adapted for an integrated requirements engineering for complex systems, like product-service systems.

    Using LCA and LCC in Planning Industrial Symbiosis: A study of the handling of sewage sludge in Malmö, Sweden2018Independent thesis Advanced level (degree of Master (Two Years)), 20 poäng / 30 hpOppgave
    Abstract [en]

    Sewage sludge is currently being disposed by spreading it out on fields, an action that recycles important nutrients such as phosphorus, but also leads to heavy metal contamination. With impeding regulation changes, possibly making it harder or impossible to keep current practice, waste water treatment plants are reviewing their options. One solution could be mono-incineration with phosphorus recovery. However, to make the sludge have a heating value high enough to avoid support fuel it needs to be thermally dried, which requires large amounts of heat. Moreover, large investments would have to be made, creating a more complex system than the current one. Industrial symbiosis could be the solution for making it both more economically and environmentally sustainable and possible, as it is possible to utilise waste heat for the drying, and collaborating with a waste incineration company to incinerate the sludge. Setting up an industrial symbiosis exchange is not always simple; knowing who benefits from what, and who should pay for what investment can be complicated. Moreover, it is often assumed that industrial symbiosis exchanges are environmentally sustainable, but it is not always the case.

    To better understand how costs should be allocated, and how exchanges should look to be both economically and environmentally sustainable, the methods life cycle analysis (LCA) and life cycle cost analysis (LCC) are suitable to use, as they allow a full view of the system, which can be broken down into different processes. The aim of this study is to see how LCA and LCC can be used on a planned symbiosis project to assess environmental and economical impacts. The results that were found was that using waste heat instead of primary produced heat was not necessarily better, both economically and environmentally in the categories acidification, eutrophication, and global warming potential. If the drying could take place solely during warmer months, through use of storage, then the heat could be produced through waste incineration, creating electricity to sell and replace marginal electricity. There was no clear cut answer to which scenario was better of the thirteen looked at in this study, as different scenarios were better in different categories, which proved the necessity of doing an LCA and a LCC, or similar methods. Moreover, the larger investments were not always the most profitable, even in the best economical scenario, showing the risk of unequal cost distribution. Similarly, the best scenario to avoid global warming potential involved using storage of dried sludge, increasing emissions for the one responsible for the storage, whilst decreasing emissions for incineration substantially.

    In summary, performing a LCA and a LCC on a planned symbiosis exchange can both show how different choices affect different categories, and help mitigate risks of uneven distribution of both costs and emissions.

    Reception of sewage in the Baltic Sea: The port's role in the sustainable management of ship wastes2018Inngår i: Marine Policy, ISSN 0308-597X, E-ISSN 1872-9460, Vol. 93, s. 207-213Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    In 2019, the special area requirements under MARPOL 73/78 Annex IV will come into effect in the Baltic Sea.This puts pressure on ports to develop reception facilities for sewage from passenger ships. This paper is built ona review of published information about the ports´ work to update sewage reception facilities and the results ofan e-mail questionnaire that was sent to a number of ports in the region, and interviews with environmentalmanagers from two major ports in the region. During the last 15 years, major investments have been made inport reception facilities in many passenger ports. However, there are still diverging views on the question if theport waste reception capacity in the region is sufficient. A few ports have for a long time been dominant asregards the reception of sewage in the Baltic Sea region, but recent increases in the ports´ waste receptioncapacity have predominantly occurred in smaller ports. This has been brought about by a replacement of mobilemeans for sewage collection with fixed connection systems or an increase of capacity of existing fixed connectionsystems. Following HELCOM recommendation, the majority of the ports have introduced a no-special-fee systembut there are differences in how this is applied.

    Möjligheterna för teknikkonsultföretag att bidra till positiv indirekt miljöpåverkan: En studie hur teknikkonsultföretag kan genomföra fler miljörelaterade uppdrag2014Independent thesis Advanced level (degree of Master (Two Years)), 20 poäng / 30 hpOppgave
    Abstract [en]

    As the environmental requirements on businesses increase from various stakeholders, the incentives for businesses to work more with environmental issues also increase. Historically, the requirements were focusing on companies with direct emissions from operations. Lately, the environmental impacts that occur indirectly as results of corporate activities have become more topical. Companies and organizations that mainly offer services often have a greater indirect than direct environmental impact. This is because they are affecting third parties, which in turn have a direct environmental impact. Technology consultancy companies are affecting the environment indirectly through their assignments and services that affect the customers' businesses or products which in turn cause environmental impact. Thus, it is interesting to study how technology consultancy companies can increase the positive indirect environmental impact. 

    The purpose of this work is to study how technology consultancy companies can increase their indirect positive impact on the environment and at the same time generate more revenue by offering environmental services. 

    Combitech is a technology consultancy company operating within many areas. Some years ago, Combitech adopted a strategy aimed at strengthening the environmental profile of the company. This has resulted in that Combitech have also launched an environmental education for all employees. Furthermore, the company has established a target implying that 10 % of all assignments towards customers will lead to environmental improvements. The objective requires that the company is accomplishing more environmental contracts with customers. However, this is not so easy for a company that traditionally has not offered environmental consulting services to any greater extent. Therefore, it is interesting for Combitech to identify the right strategy in order to sell more environmental services. This work is based on a case study that is focusing on Combitech. 

    The methods implemented to answer the purpose in this work are of qualitative kind. Literature studies were first conducted for studying previous research in the area. This was followed by document studies, interviews, and observations internally at Combitech in order to investigate the company's current situation. The major part of this work was the interview process with Combitech’s customers to examine their approach to environmental management and environmental services. Based on a benchmarking of competing companies’ environmental profiles, Combitech’s current environmental work and responses from client interviews, an analysis was made to identify what activities and actions Combitech could implement in order to sell more environmental services. Then, the results were discussed in a broader perspective in order to distinguish how much that is generalizable to other technology consultancy companies. 

    There are varying interests among customers regarding environment related issues. There is currently a great gap of knowledge and experience at Combitech regarding environment. By training the personnel within environmental related issues the competence gap will be reduced. Sellers and business developers who hold environmental expertise can help educate customers about environmental services that suit the specific client's business. Combitech should initially focus on selling environmental services to existing customers where framework agreements exists and also to the customers of smaller sizes where Combitech acting as the single or one of the few consulting firms. This is because Combitech in these situations has an advantage over competing consulting firms which may not quote without a framework agreement or that do not have existing cooperation with a customer who is Combitech’s existing customer. The key for selling more environmental related services is to offer customers tailor made services that suits the unique demand of different customers.

    Design Guidelines Developed from Environmental Assessments: A Design Tool for Resource-Efficient Products2020Inngår i: Sustainability, E-ISSN 2071-1050, Vol. 12, nr 12, artikkel-id 4953Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The circular economy provides a potential solution to the take-make-dispose model of resource use that currently characterizes the economy. Guidelines for the circular economy often consist of prioritized lists of measures to achieve resource efficiency. However, for the purpose of designing products, such general prioritizations of measures are less useful. Instead, the tool developed in this study is based on learnings from numerous life cycle assessments and provides design recommendations for the improved resource efficiency of products based on product characteristics. The tool includes measures over the whole lifecycle of different products that lead to improved resource efficiency. The tool also demonstrates how different product types, such as different varieties of durable and consumable products, can become more resource-efficient and when trade-offs occur over the lifecycle of a product. The tool was tested in a design case where its usefulness and usability were evaluated using a comparative life cycle assessment and a questionnaire. The evaluation shows the tool is informative and provides design suggestions that lead to improved resource efficiency. The tool is considered usable and could be implemented in design practice.

    Developing integration in a local industrial ecosystem: An explorative approach2007Inngår i: Business Strategy and the Environment, ISSN 0964-4733, Vol. 16, nr 6, s. 442-455Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The objective of this study is to develop and evaluate an approach for initiating development of a local industrial symbiosis network. By maintaining the broad perspective of industrial symbiosis, which includes both material and energy flow analysis, and also taking into account the internal energy use and possibilities for energy savings, we aim to achieve a better system view that avoids both sub-optimizations and unhealthy dependencies. The approach is applied to a case based on the cooperation between the forest industry, municipality and energy service company in a small town in southern Sweden. Several possibilities for improving material and energy use by increasing integration were identified. It was concluded that it is important to have a genuine knowledge of the system studied and close contact with the actors involved, since a simple analysis of energy and material flows is not sufficient to decide which solutions might be more advantageous. It is also important to have a flexible system boundary looking at the system from different perspectives and at different levels to find the best uses for existing energy and material streams.

    Developing integration in a local industrial ecosystem: Human dimensionsManuskript (preprint) (Annet vitenskapelig)
    Abstract [en]

    The objective of this study is to evaluate the human dimensions of improving energy and material-use efficiency of a system through increased integration and exchange between local actors. The results are based on a case study of a Swedish municipality with developed forest industry. The actors' views are discussed together with the most important factors to enable increased integration and exchange to take place. The greatest barriers found were lack of knowledge and resources, attitudes, time frames, development consent, and lack of continuity and local power for some companies. One conclusion is that the municipal authority could have a role as coordinator of local integration projects. However, tius role can be impeded by the weak integration of different divisions in the municipality's organisation and it is suggested that companies with integration as their business concept can be key actors when developing more integrated networks. It was also clear that intra-organisational issues may impede inter-organisational integration.

    Early-warning analysis of crowd stampede in metro station commercial area based on internet of things2019Inngår i: Multimedia tools and applications, ISSN 1380-7501, E-ISSN 1573-7721, Vol. 78, nr 21, s. 30141-30157Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Crowd stampede has attracted significant attention of emergency management researchers in recent years. Early-warning of crowd stampede in metro station commercial area is discussed in this paper under the context of Internet of Things (IoT). Metro station commercial area is one of the entity carriers of E-commerce. IOT is a new concept of realizing intelligent sense, monitoring, tracking and management, which can be used in early-warning analysis of crowd stampede in metro station. Stampede risk early-warning in commercial area plays an important role in ensuring the operation of e-commerce online. Firstly, the laws and characteristics of the crowd movement in the commercial area of metro station are studied, which include the laeuna effect, block effect and aggravation effect. Secondly, the early-warning paradigm is constructed from four dimensions, ie. function, modules, principle and process. And then, under the IOT environment, the AHPsort II is applied to integrate the early-warning information and classify the stampede risk level. Finally, the paper takes the commercial area of Wuhan A metro station as an example to verify the practicability and effectiveness of the AHPsort II application to early-warning of crowd stampede in metro station commercial area.

    Development of a lean manufacturing framework to enhance its adoption within manufacturing companies in developing economies2020Inngår i: Journal of Cleaner Production, ISSN 0959-6526, E-ISSN 1879-1786, Vol. 245, artikkel-id 118726Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The urgent need to reduce negative corporate environmental impacts while enhancing their financial strength and positive societal benefits is attracting company leaders to implement various quality improvement systems such as lean manufacturing, six sigma, sustainable manufacturing, and circular economy concepts, approaches and technologies. All of these approaches are valuable, with Lean Manufacturing (LM) among the leading systems, if implemented within an appropriate framework. In that context, the objective of the authors was to document the drivers for improving implementation of LM within manufacturing companies. Implementation of LM practices is already providing competitive advantages such as improvements in product quality, productivity, worker health and safety and customer satisfaction in developed countries but has not been widely implemented in companies in developing countries. To help to enhance implementation of LM in developing countries, the authors developed a framework for enhancing the adoption of lean manufacturing processes in such companies. The hybrid Fuzzy Analytical Hierarchy Process (FAHP)- Decision Making Trial and Evaluation Laboratory (DEMATEL) tools were used as the framework to identify and to quantify the interrelationships among the drivers for implementation of LM. This hybrid approach facilitated documentation of the relative importance and priority of the thirty-one lean manufacturing drivers. The results revealed that improved shop-floor management, quality management, and manufacturing strategy drivers were among the most critical drivers, which enhance LM adoption. These findings are beneficial for company leaders and researchers working to improve environmental, economic and societal health, especially within companies in developing countries.

    Sustainable operations-oriented painting process optimisation in automobile maintenance service2021Inngår i: Journal of Cleaner Production, ISSN 0959-6526, E-ISSN 1879-1786, Vol. 324, artikkel-id 129191Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Building a more sustainable society is an urgent requirement for todays service-oriented manufacturing enterprises, such as automobile maintenance firms. In automobile maintenance service, traditional painting process scheduling scheme usually only considers the profits of enterprises, ignoring the requirements of customers or other stakeholders. To address this gap and achieve sustainable operations of enterprises in the long term, this paper concentrated on the vehicle scheduling of painting process problem with the concern of the demands of managers, workers, customers, governments and non-government environmental protection organisations. This problem was formulated as a nonlinear 0-1 integer programming model to minimise makespan (MP), total pollutant emissions (TPE) and total customers perceived dissatisfaction (TCPDS). A genetic algorithm was designed to solve the model, and a practical case using data from both the information system and the survey was performed to test the performance of the proposed model and algorithm. Computational results revealed that the genetic algorithm performed well in terms of validity and stability. Pareto solutions demonstrated that optimising task sequences helped increase customers perceived satisfaction while improving the makespan of vehicle painting, decreased paint waste, and reduced worker health and safety risks. Some of the increases in the percentage of well-timed customer service reservations were catalysed by the method that combined tiered pricing, related to delivery times, the automobile painting efficiency, which improved customers perceived satisfaction. This paper also further guides managers to incorporate sustainable development into operations in service-oriented manufacturing enterprises.

    Developing a grading tool for sustainable design of structural systems in buildings2021Independent thesis Advanced level (degree of Master (Two Years)), 20 poäng / 30 hpOppgave
    Abstract [en]

    Construction is known for consuming large quantities of raw materials and high amounts of energy. In 2018, the construction industry was responsible for 6% of global energy consumption, 11% of global CO2 emissions, and approximately 36% of the total waste in the European Union. These drawbacks are just a part of the gap between the construction sector and Sustainability, which can also be perceived as challenges to the industry and demands for new and innovative strategies to increase Sustainability. For example, recent efforts of EcoDesign on structural systems show a trend in the importance of materials efficiency, durability, adaptability, and reuse.   

    This thesis aims to create a set of guidelines that will help designers and other construction stakeholders apply Design for Deconstruction and Adaptability DfD/A principles to increase the knowledge of how structural design and structural systems in buildings can be designed to promote Sustainability. For this purpose, a grading tool to assess structural systems based on the ISO 20887 was developed.

    The general methodology for this research was adapted from Design Research Methodology with a particular focus on the Product Development approach for the tool development. A literature Review was conducted in both scientific and grey literature to identify relevant information and current efforts on sustainable design of structural systems and application of DfD/A principles on the construction sector. Three additional methods for data collection were used: (1) questionnaire for identification of customer needs and expectations, (2) benchmarking to identify similar tools, strategies, and certifications systems that include sustainability performance in buildings; and (3) workshops with the purpose to rate the usefulness quality of the tool based on the application of the tool by potential users in different case studies. 

    A ready-to-use computer-based EcoDesign tool was developed. The assessment performed by this tool consists of an indicator system of DfD/A strategies to enhance sustainable development by improving material efficiency and stimulate a circular economy in the construction sector. A top-down approach was used for the concept generation, which starts with the ReBuilding Index as an indicator of sustainable performance for structural systems. This index is based on five categories defined on the relationship of the DfD/A principles with the design process of the structural system. A total of 20 principles are distributed in these categories, defined by 54 strategies to reach the goal of the principles.    

    The tool was tested by 11 potential users with different roles in the construction sector. Five case studies were selected to grade the design of five different typologies of structural systems. The usefulness quality of the tool was evaluated based on indicators of usability, utility, and user experience. It was found that developing the tool based on DfD/A principles and the ISO 20887 gave the tool a solid theoretical background and a flexible structure that can be used for sustainable design or as part of an extensive framework of certification systems or ecolabel programs.

    The tool accomplishes the goal of grading and helping to improve the structural design. However, during the evaluation of the tool, many barriers and difficulties of application were found. Therefore, these findings and obstacles are instead identified as challenges and turn them into opportunities for improvements in future versions of the tool.

    The diffusion of biogas systems in Brazil2024Licentiatavhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    Brazil is one of the largest economies in the Global South. Because of the country’s strong agribusiness and large population, it has a huge potential for biogas production that has yet to be realized. Biogas systems could potentially address a broad range of social, environmental, and economic issues, such as improving accessibility to clean energy sources in rural areas, alternative cooking fuel, and providing proper treatment of organic waste. Hence, biogas systems can play an important role in sustainability transitions by improving the environmental performance of energy generation, waste management systems, and food production. However, despite the availability of substrate for biogas production and the multiple benefits that biogas systems could bring, there is still a large implementation gap.  

    Biogas systems go beyond technical components and involve a multitude of stakeholders, infrastructure, knowledge, and formal and informal institutions. Therefore, the diffusion of biogas systems cannot be explained only by analyzing the technical components of biogas systems. Previous studies have explored the influences of societal contexts on technological diffusion, but these explored countries in the Global North. However, social, economic, and political aspects differ significantly between Global North and Global South countries.  

    This thesis aims to explain how societal contexts influence the diffusion of biogas systems in Brazil. The thesis distinguishes between societal contexts, delineating them as societal environments and socio-economic structures. Societal environments refer to the circumstances and aspects surrounding the diffusion process where alignment processes between new socio-technical systems and society happen across five environments: user, business, regulatory, cultural, and trans-local. Socio-economic structures refer to societal arrangements that shape social and economic aspects of society. The Varieties of Capitalism framework provides a tool for comparison of the socio-economic structures of different countries in the Global North and South. The thesis relies on case studies based on quantitative and qualitative data from documents (scientific articles, news articles, technical reports, research reports, official documents by governmental agencies, and policies) and interviews.   

    Societal contexts appear to be more unstable and fragmented compared to counterparts in the Global North, influencing the diffusion of biogas systems. Hierarchical structures in Brazil lead to power disparities between administrative levels (municipal, state, and federal levels), impacting policymaking and hindering local-level biogas system configurations. The thesis highlights socio-economic diversity among Brazilian states and how it influences where and which biogas system configurations are formed. This thesis emphasizes that studies on biogas systems’ potential should consider contextual aspects beyond substrate availability to comprehensively understand biogas systems diffusion in diverse settings.

    Abstract [en]

    Policy mixes are needed to overcome the different barriers hindering sustainability transitions. This creates the need for policy coherence. Policy coherence studies in sustainability transitions literature are dominated by European cases, limiting their generalizability. This article analyzes policy mixes related to biogas systems and their related coherence issues, and, how that influences biogas production and use in Brazil. We identified policy coherence within and between biogas related sectors and over time, showing how the pre-conditions for biogas production, distribution and use differ considerably between the Brazilian states. This points to a need for decentralized governance structures to enable policy differentiation, as a complement to policy coherence. The article concludes that the characteristics of biogas systems as being locally embedded constitutes a challenge in hierarchical market economies such as Brazil, where policy development, resource mobilization and allocation are highly centralized.

    Abstract [en]

    The transition to a circular economy relies on systems that facilitate waste recovery and recirculation of resources. These systems are based on certain enabling technologies. The aim of this paper is to explain how socio-economic structures influence the diffusion of such technologies. It applies a framework built on societal embedding and varieties of capitalism to compare the diffusion of anaerobic digestion (AD) in Sweden in northern Europe and Paraná in southern Brazil. Both Sweden and Paraná have experienced accelerated diffusion of AD, but there are significant differences in the respective diffusion patterns. The comparative analysis points to a tradeoff between system complexity and speed of diffusion. It illustrates how AD can be presented as a solution to various problems, and it further shows how the specific problems that gain attention shape diffusion patterns. By showing how socio-economic structures influence the appointment of problem owners, their agency, and legitimate forms of institutional support, the analysis demonstrates how economic systems condition technology diffusion.

    Abstract [en]

    The diffusion of new socio-technical systems is essential for tackling contemporary sustainability challenges. Against the backdrop of literature on societal embedding this paper explores the diffusion of socio-technical systems as a process of co-constructing innovations and their societal environments. This paper uses a comparative research design to analyze the diffusion of biogas systems across four Brazilian states. In doing so, this paper makes two contributions. First, it contributes with nuances regarding the fit-and-conform and stretch-and-transform typology, showing that innovations exhibit not only hybrid patterns across societal environments but also across different sectors (e.g. agriculture, sanitation, and waste management). Furthermore, innovations exhibit hybrid conform and transform patterns across different administrative levels (e.g. municipal, state, and national). Second, it broadens the empirical base of societal embedding studies to the Global South and biogas technologies which represent a fragmented context and a complex innovation, respectively. Altogether, the paper contributes to further understanding of why multi-functional socio-technical systems, such as biogas systems, diffuse in certain contexts and not in others.

    The diffusion of biogas technologies in the Brazilian context: A comparative case study in two Brazilian states2020Independent thesis Advanced level (degree of Master (Two Years)), 20 poäng / 30 hpOppgave
    Abstract [en]

    Brazil is one of the largest biomass producers in the world, thus it has a huge potential for biogas production across all its territory. Nowadays, biogas production remains largely unexplored, representing just a small fraction of its potential. The adoption of biogas technologies has grown over the past years, but it is unevenly distributed across Brazilian states. This master thesis investigates the conditions under which the widespread diffusion of biogas technologies can be enabled in the Brazilian context by looking at the factors that influence the adoption of biogas technologies and why it differs across the Brazilian territory. Technological innovation systems (TIS), societal embedding, and diffusion of innovation theory are combined in the theoretical framework to create a broad understanding of the diffusion process of biogas technologies in Brazil. While TIS focusses on what are the functions been performed within the system, Societal embedding contributes to the understanding of why technological diffusion may not happen in the same way in different regions and how technologies are rooted in society. Diffusion of innovation theory adds to the importance of individual choices and strategies in the adoption of technologies. A comparative case study was design between the states São Paulo and Paraná. 16 semi-structured interviews served as the main research instrument with the support of document studies. When looking at the factors that could impact the adoption of biogas technologies the presence of specialized actors that can offer technical support to the implementation of projects locally proved to be positive considering that biogas technologies are still novel in Brazil. The unreliability of the energy grid in rural regions also favours the adoption of biogas technologies for electricity generation in agriculture properties that can combined waste treatment with energy security. Access to financial and human resources is still the largest barrier for the diffusion of biogas technologies. Financial institutions are at large unprepared to offer good conditions for the implementation of biogas projects, mainly because they do not understand the singularities of these projects. The adoption of biogas technologies in the case studies was mainly dictated by the economic activities in place, which shaped the view on biogas technologies. The complexities of the regulatory environment in Brazil could explain why electricity generation is still the main application of biogas technologies as the electricity market is regulated at national level while gas markets are the responsibility of individual states. When biogas technologies are portraited as a tool for sustainable development, other advantages of these technologies are highlighted – environmental and social benefits such as waste treatment and job creation – creating a better claim for biogas technologies which could boost adoption.

    Barriers to smart waste management for a circular economy in China2019Inngår i: Journal of Cleaner Production, ISSN 0959-6526, E-ISSN 1879-1786, Vol. 240, artikkel-id UNSP 118198Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Waste management requires a new vision and drastic improvements for a transition to a zero-waste circular economy. In reality, however, many economies are producing more and more waste, which poses a serious challenge to environmental sustainability. The problem is enormously complex as it involves a variety of stakeholders, demands behavioral changes, and requires a complete rethinking of the current waste management systems and the dominant linear economic model. Smart enabling technologies can aid in a transformation of waste management toward a circular economy, but many barriers persist. This study first shortlists twelve important barriers to smart waste management in China based on interviews with experienced practitioners. It then prioritizes these barriers through a scientific prioritization technique, fuzzy Decision-Making Trial and Evaluation Laboratory (DEMATEL), based on the survey data from three representative stakeholders. It identified three key causal barriers: the lack of regulatory pressures, the lack of environmental education and culture of environmental protection, and the lack of market pressures and demands. Practical and theoretical implications were discussed based on the research results and findings. (C) 2019 Elsevier Ltd. All rights reserved.

    A systematic review of recent developments in disaster waste management2019Inngår i: Journal of Cleaner Production, ISSN 0959-6526, E-ISSN 1879-1786, Vol. 235, s. 822-840Artikkel, forskningsoversikt (Fagfellevurdert)
    Abstract [en]

    Disaster waste management received increasing attention in recent years, but there was no review updating the evolving development after the study of Brown et al. (2011a). To explore how the topics in disaster waste management evolved in recent years and to analyze whether the gaps identified by Brown et al. (2011a) are covered, 82 papers published from 2011 to 2019 were selected from the Scopus database based on the defined process and criteria. This paper systematically examines the disaster waste management research from nine aspects of planning, waste, waste treatment options, environment, economics, social considerations, organizational aspects, legal frameworks and funding. The results suggested that there were no obvious changes or developments in the field of disaster waste management, although a few research gaps have been addressed, such as waste separation, waste quantities, case studies of incineration and waste to energy, direct economic effects, social considerations as well as application of GIS technology. Except for the comparative studies, future directions were suggested by the gaps that persist since Brown et al. (2011a) and the new gaps that were identified in this review. (C) 2019 Elsevier Ltd.

    Digital twin-based opti-state control method for a synchronized production operation system2020Inngår i: Robotics and Computer-Integrated Manufacturing, ISSN 0736-5845, E-ISSN 1879-2537, Vol. 63, artikkel-id 101892Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The intelligent manufacturing strategy and customer demand have mutually promoted each other. Also, the production mode is shifting towards customized production, and more rental resources or services are introduced to the production system, therefore, the systems are becoming more complex. Compared with traditional production systems, such systems have some new features, this work calls this type of system as a synchronized production operation system (SPOS). Under such circumstances, production systems are influenced by more frequent uncertainties, and the planning-based production decision and control approach is no longer applicable. The opti-state control (OsC) method is proposed to help SPOS keep in an optimal state when uncertainties affect the system. Besides, a digital twin-based control framework (DTCF) is designed for getting the full element information needed for decision making. Based on the comprehensive information of the production system obtained by the DTCF, the OsC method is introduced to the virtual control layer to formulate the optimal target guiding the path of the system in real time through the dynamic matching mechanism (qualitative perspective). Then multi-stage synchronized control with analysis target cascading (ATC) method is used to get the local optimal state decisions (quantitative perspective). From both qualitative and quantitative aspects to ensure the system is under an optimal target path for optimal operation procedure. At last, a case study in a large-size paint making company in China is used to validate the effectiveness of the approach.

    IoT-enabled dynamic lean control mechanism for typical production systems2019Inngår i: Journal of Ambient Intelligence and Humanized Computing, ISSN 1868-5137, E-ISSN 1868-5145, Vol. 10, nr 3, s. 1009-1023Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The emergence and subsequent popularization of lean has been one of the most significant developments in the history of operations management. However, there is a lack of systematic theory on the control framework underlying lean production. It is therefore difficult to conduct more in-depth research on Lean theory, specifically in the context of emerging technologies as smart manufacturing or Industry 4.0. In this study, process control theory is used to re-define several major lean methods and tools. Then a Lean-Oriented Optimum-State Control Theory (L-OSCT) is proposed that integrates these lean methods and tools into optimum-state control theory. On the level of method and mechanism, we adopt a recently emerged synchronization approach to obtain global-wide leanness of a large-scale system. L-OSCT provides dynamic process control in industrial networking systems. At last, a case study in a large-size paint making company in China is used to validate the effectiveness of the approach.

    Home health care routing and scheduling in densely populated communities considering complex human behaviours2023Inngår i: Computers & industrial engineering, ISSN 0360-8352, E-ISSN 1879-0550, Vol. 182, artikkel-id 109332Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    This study focuses on the home health care routing problem (HHCRP) in the scenario of high population density areas where many elders live closely together. This study considers two main objectives. The first is to reduce travel and wait times for nurses or elders. The second concerns socially related objectives in scheduling problems, such as quality of life and empowerment, by considering assumptions related to the acquaintanceship and mutual preferences of nurses and elders. This study models the effects of mutual preferences and acquain-tanceship on service time in HHCRP. We use the Markov decision process and chance-constrained programming (CCP) to model the system to conserve the sequential service provision parameters and better represent the influence of stochastic service times. Because traditional deterministic algorithms cannot solve such a model, we apply a model-free reinforcement learning algorithm, Q-learning (QL), as well as the ant colony optimisation (ACO) algorithm. Thus, we tackle this problem by developing a model and algorithm to solve complex, large-scale systems. This studys theoretical and practical contributions are verified by feedback from researchers and practitioners.

    Contribution of potential clean trucks in carbon peak pathway of road freight based on scenario analysis: A case study of China2022Inngår i: Journal of Cleaner Production, ISSN 0959-6526, E-ISSN 1879-1786, Vol. 379, artikkel-id 134669Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Reducing the carbon emissions from trucks is critical to achieving the carbon peak of road freight. Based on the prediction of truck population and well-to-wheel (WTW) emission analysis of traditional diesel trucks and po-tential clean trucks including natural gas, battery-electric, plug-in hybrid electric, and hydrogen fuel cell, the paper analyzed the total greenhouse gas (GHG) emissions of Chinas road freight under four scenarios, including baseline, policy facilitation (PF), technology breakthrough (TB), and PF-TB. The truck population from 2021 to 2035 is predicted based on regression analysis by selecting the data from 2002 to 2020 of the main variables, such as the GDP scale, road freight turnover, road freight volume, and the number of trucks. The study forecasts the truck population of different segments, such as mini-duty trucks (MiDT), light-duty trucks (LDT), medium-duty trucks (MDT), and heavy-duty trucks (HDT). Relevant WTW emissions data are collected and adopted based on the popular truck in Chinas market, PHEVs have better emission intensity, especially in the HDT field, which reduces by 51% compared with ICEVs. Results show that the scenario of TB and PF-TB can reach the carbon peak with 0.13% and 1.5% total GHG emissions reduction per year. In contrast, the baseline and PF scenario fail the carbon peak due to only focusing on the number of clean trucks while lacking the restrictions on the GHG emission factors of energy and ignoring the improvement of trucks energy efficiency, and the total emissions increased by 29.76% and 16.69% respectively compared with 2020. As the insights, adopting clean trucks has an important but limited effect, which should coordinate with the transition to low carbon energy, and the melioration of clean trucks to reach the carbon peak of road freight in China.

    The Internet of Things enabled real-time scheduling for remanufacturing of automobile engines2018Inngår i: Journal of Cleaner Production, ISSN 0959-6526, E-ISSN 1879-1786, Vol. 185, s. 562-575Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Typical challenges that managers of remanufacturing face are composed of the lack of timely, accurate, and consistent information of remanufacturing resources. Therefore, it is difficult to implement real-time production scheduling for the shop floor. To address this problem, the authors applied the concept of the Internet of Things to the remanufacturing of automobile engines to form an Internet of Manufacturing Things environment. Under the Internet of Manufacturing Things, an identification technology for disassembled engine parts was designed, and the real-time status of the remanufacturable resources can be monitored. Based on the captured remanufacturing information, a real-time production scheduling method was developed, and a mathematical model was developed to achieve cost reduction, dynamic management of remanufacturable resources, and energy consumption decrease. To obtain an optimal solution, a Pareto-based optimization method was used. Finally, a case study was performed to analyze the effectivity of the proposed method. The results showed that the remanufacturing cost and energy consumption were reduced by 34% and 34% respectively, and the worker load rate was more balanced. These improvements can contribute to more sustainable development and greener production within the remanufacturing industry, especially for remanufacturing of automobile engines.

    A big data driven analytical framework for energy-intensive manufacturing industries2018Inngår i: Journal of Cleaner Production, ISSN 0959-6526, E-ISSN 1879-1786, Vol. 197, s. 57-72Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Energy-intensive industries account for almost 51% of energy consumption in China. A continuous improvement in energy efficiency is important for energy-intensive industries. Cleaner production has proven itself as an effective way to improve energy efficiency and reduce energy consumption. However, there is a lack of manufacturing data due to the difficult implementation of sensors in harsh production environment, such as high temperature, high pressure, high acid, high alkali, and smoky environment which hinders the implementation of the cleaner production strategy. Thanks to the rapid development of the Internet of Things, many data can be sensed and collected in the manufacturing processes. In this paper, a big data driven analytical framework is proposed to reduce the energy consumption and emission for energy-intensive manufacturing industries. Then, two key technologies of the proposed framework, namely energy big data acquisition and energy big data mining, are utilized to implement energy big data analytics. Finally, an application scenario of ball mills in a pulp workshop of a partner company is presented to demonstrate the proposed framework. The results show that the energy consumption and energy costs are reduced by 3% and 4% respectively. These improvements can promote the implementation of cleaner production strategy and contribute to the sustainable development of energy intensive manufacturing industries.

    A framework for Big Data driven product lifecycle management2017Inngår i: Journal of Cleaner Production, ISSN 0959-6526, E-ISSN 1879-1786, Vol. 159, s. 229-240Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Optimization of the process of product lifecycle management is an increasingly important objective for manufacturing enterprises to improve their sustainable competitive advantage. Originally, this approach was developed to integrate the business processes of an organization and more effectively manage and utilize the data generated during lifecycle studies. With emerging technologies, product embedded information devices such as radio frequency identification tags and smart sensors are widely used to improve the efficiency of enterprises routine management on an operational level. Manufacturing enterprises need a more advanced analysis approach to develop a solution on a strategic level from using such lifecycle Big Data. However, the application of Big Data in lifecycle faces several challenges, such as the lack of reliable data and valuable knowledge that can be employed to support the optimized decision-making of product lifecycle management. In this paper, a framework for Big Data driven product lifecycle management was proposed to address these challenges. Within the proposed framework, the availability and accessibility of data and knowledge related to lifecycle can be achieved. A case study was presented to demonstrate the proof-of-concept of the proposed framework. The results showed that the proposed framework was feasible to be adopted in industry, and can provide an overall solution for optimizing the decision-making processes in different phases of the whole lifecycle. The key findings and insights from the case study were summarized as managerial implications, which can guide manufacturers to ensure improvements in energy saving and fault diagnosis related decisions in the whole lifecycle.

    A big data analytics architecture for cleaner manufacturing and maintenance processes of complex products2017Inngår i: Journal of Cleaner Production, ISSN 0959-6526, E-ISSN 1879-1786, Vol. 142, nr 2, s. 626-641Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Cleaner production (CP) is considered as one of the most important means for manufacturing enterprises to achieve sustainable production and improve their sustainable competitive advantage. However, implementation of the CP strategy was facing barriers, such as the lack of complete data and valuable knowledge that can be employed to provide better support on decision-making of coordination and optimization on the product lifecycle management (PLM) and the whole CP process. Fortunately, with the wide use of smart sensing devices in PLM, a large amount of real-time and multi-source lifecycle big data can now be collected. To make better PLM and CP decisions based on these data, in this paper, an overall architecture of big data-based analytics for product lifecycle (BDA-PL) was proposed. It integrated big data analytics and service-driven patterns that helped to overcome the above-mentioned barriers. Under the architecture, the availability and accessibility of data and knowledge related to the product were achieved. Focusing on manufacturing and maintenance process of the product lifecycle, and the key technologies were developed to implement the big data analytics. The presented architecture was demonstrated by an application scenario, and some observations and findings were discussed in details. The results showed that the proposed architecture benefited customers, manufacturers, environment and even all stages of PLM, and effectively promoted the implementation of CP. In addition, the managerial implications of the proposed architecture for four departments were analyzed and discussed. The new CP strategy provided a theoretical and practical basis for the sustainable development of manufacturing enterprises.

    Game theory based real-time multi-objective flexible job shop scheduling considering environmental impact2017Inngår i: Journal of Cleaner Production, ISSN 0959-6526, E-ISSN 1879-1786, Vol. 167, s. 665-679Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Production scheduling greatly contributes to optimising the allocation of processes, reducing resource and energy consumption, lowering production costs and alleviating environmental pollution. It is an effective way to progress towards green manufacturing. With the extensive use of the Internet of Things in the manufacturing shop floor, a huge amount of real-time data is created. A typical challenge is how to achieve the real-time data-driven optimisation for the manufacturing shop floor to improve energy efficiency and production efficiency. To address this problem, a dynamic game theory based two-layer scheduling method was developed to reduce makespan, the total workload of machines and energy consumption to achieve real-time multi-objective flexible job shop scheduling. To obtain an optimal solution, a sub-game perfect Nash equilibrium solution was designed. Then, a case study was employed to analyse the performance of the proposed method. The results showed that the makespan, the total workload of machines and energy consumption were reduced by 4.5%, 8.75%, and 9.3% respectively. These improvements can contribute to sustainable development and cleaner production of manufacturing industry. (C) 2017 Elsevier Ltd. All rights reserved.

    Analytical target cascading for optimal configuration of cloud manufacturing services2017Inngår i: Journal of Cleaner Production, ISSN 0959-6526, E-ISSN 1879-1786, Vol. 151, s. 330-343Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Combining with advanced technologies (e.g., cloud computing, Internet of Things, and service-oriented technology), cloud manufacturing was proposed and gained wide attention. By managing a huge amount of distributed and idle manufacturing resources to meet various manufacturing requirements, cloud manufacturing provides sustainable means for promoting cleaner production. Manufacturing service configuration plays an important role in implementing cloud manufacturing. Most research adopted central optimization methods to get optimal service configuration results. However, these all-in-one methods with an individual decision model can hardly maintain the autonomous decision rights of different service providers. Consequently, service providers may lose their flexibility to achieve private decision objectives, which is unfavorable for keeping the sustainable competitive advantages of enterprises. In this paper, a decentralized decision mechanism named analytical target cascading is introduced to solve the manufacturing service configuration problem. An analytical target cascading model for the manufacturing service configuration problem is proposed based on the hierarchical structure of cloud manufacturing system. Elements in the proposed model are formulated and solved in a loose coupling and distributed manner. The situation when alternative service providers owned autonomous decision rights to configure their respective upstream manufacturing stages is also considered. A case study is employed to verify the effectiveness of analytical target cascading in solving the manufacturing service configuration problem. It shows that analytical target cascading can not only obtain the same manufacturing service configuration results as central optimization method but also maintain the autonomous decision rights of different service providers.

    Long/short-term utility aware optimal selection of manufacturing service composition towards Industrial Internet platform2019Inngår i: IEEE Transactions on Industrial Informatics, ISSN 1551-3203, E-ISSN 1941-0050, Vol. 15, nr 6, s. 3712-3722Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    As numerous Industrial Internet platforms emerge, manufacturing services are shared among multiple stakeholders more frequently than ever. The optimal selection of shared manufacturing service composition (MSC) should both promise the task completion and the stakeholders’ satisfaction. However, as commercial entities, stakeholders concentrate on not only the temporary benefits but also the long-term acquisitions. Most of the existing MSC problems neglect the stakeholders’ prospect on the manufacturing service sharing. This leads to the disappointment and dissatisfaction of the stakeholders with long-term expectations, who will abandon the participation in Industrial Internet platform. Therefore, the long/short-term preferences of various stakeholders should be satisfied and balanced. In this paper, the long/short-term preferences of three sides (provider, consumer, and operator) are discussed. And the models considering short-term utility of a consumer and long-term utility of providers, are established. The potential tasks assigned to providers are taken into account to estimate the long-term utility if the current task is accepted. Then, to solve the bi-objective optimization problem, an improved Non-dominated Sorting Genetic Algorithm-II algorithm, combining Tabu search and improved K-means mechanism, is proposed to find the optimal solution set. Finally, the effectiveness of the method is verified by the experimental results in terms of solution diversity, astringency and stability, in which a finding is further observed that the changes of consumers’ preferences have little impact on the long-term utility of providers.

    Consensus aware manufacturing service collaboration optimization under blockchain based Industrial Internet platform2019Inngår i: Computers & industrial engineering, ISSN 0360-8352, E-ISSN 1879-0550, Vol. 135, s. 1025-1035Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    To realize collaboration among distributed enterprises, manufacturing service collaboration on Industrial Internet platform is an efficient method. However, the low degree of participation resulted by the sense of distrust, dissatisfaction, and insecurity hinders the widely application of Industrial Internet platform. Therefore, a secure, trustworthy, and multi-user satisfied manufacturing service collaboration method is in urgent need. A blockchain based platform could be utilized to support collaboration among distributed participants to complete trustworthy transactions. In addition, in order to satisfy multiple users, there should be a suitable collaboration mechanism that allows interest-independent participants to fulfil their short/long-term expectations and guide them to a consensus. Based on the establishment of the underlying data and network layer of the blockchain, the collaboration optimization of manufacturing services based on consensus is proposed. By utilizing Memetic algorithm, both the long-term utility of providers and the short-term utility of consumers are combined to choose the optimal providers for the tasks. The providers are selected with higher satisfaction degree of consumers.

    Smart Product-Service Systems Solution Design via Hybrid Crowd Sensing Approach2019Inngår i: IEEE Access, E-ISSN 2169-3536, Vol. 7, s. 128463-128473Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The third wave of information technology (IT) competition has enabled one promising value co-creation proposition, Smart PSS (smart product-service systems). Manufacturing companies offer smart, connected products with various e-services as a solution bundle to meet individual customer satisfaction, and in return, collect and analyze usage data for evergreen design purposes in a circular manner. Despite a few works discussing such value co-creation business mechanism, scarcely any has been reported from technical aspect to realizing this data-driven manufacturer/service provider-customer interaction cost-effectively. To fill this gap, a novel hybrid crowd sensing approach is proposed, and adopted in the Smart PSS context. It leverages large-scale mobile devices and their massive user-generated/product-sensed data, and converges with reliable static sensing nodes and other data sources in the smart, connected environment for value generation. Both the proposed hybrid crowd sensing conceptual framework and its systematic information modeling process are introduced. An illustrative example of smart water dispenser maintenance service design is given to validate its feasibility. The result shows that the proposed approach can be a promising manner to enable value co-creation process cost-effectively.

    Microbial rRNA gene expression and co-occurrence profiles associate with biokinetics and elemental composition in full-scale anaerobic digesters2018Inngår i: Microbial Biotechnology, ISSN 1751-7907, E-ISSN 1751-7915, Vol. 11, nr 4, s. 694-709Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    This study examined whether the abundance and expression of microbial 16S rRNA genes were associated with elemental concentrations and substrate conversion biokinetics in 20 full-scale anaerobic digesters, including seven municipal sewage sludge (SS) digesters and 13 industrial codigesters. SS digester contents had higher methane production rates from acetate, propionate and phenyl acetate compared to industrial codigesters. SS digesters and industrial codigesters were distinctly clustered based on their elemental concentrations, with higher concentrations of NH3-N, Cl, K and Na observed in codigesters. Amplicon sequencing of 16S rRNA genes and reverse-transcribed 16S rRNA revealed divergent grouping of microbial communities between mesophilic SS digesters, mesophilic codigesters and thermophilic digesters. Higher intradigester distances between Archaea 16S rRNA and rRNA gene profiles were observed in mesophilic codigesters, which also had the lowest acetate utilization biokinetics. Constrained ordination showed that microbial rRNA and rRNA gene profiles were significantly associated with maximum methane production rates from acetate, propionate, oleate and phenyl acetate, as well as concentrations of NH3-N, Fe, S, Mo and Ni. A co-occurrence network of rRNA gene expression confirmed the three main clusters of anaerobic digester communities based on active populations. Syntrophic and methanogenic taxa were highly represented within the subnetworks, indicating that obligate energy-sharing partnerships play critical roles in stabilizing the digester microbiome. Overall, these results provide new evidence showing that different feed substrates associate with different micronutrient compositions in anaerobic digesters, which in turn may influence microbial abundance, activity and function.

    Regenerative economics at the service of islands: Assessing the socio-economic metabolism of Samothraki in Greece2023Inngår i: Journal of Cleaner Production, ISSN 0959-6526, E-ISSN 1879-1786, Vol. 408, artikkel-id 137136Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    For many islands, the answer to the question "why a locally, self-sustaining, and regenerative economy is needed?" is clear. The struggle often lies in the "how". Here, we argue that tools from regenerative economics, which follow an island economy-as-an-organism analogy, offer valuable and complementary insights to socio-metabolic research. Indicators from flow-based and information-based ecological network analysis can quantify proper- ties of an islands socio-economic metabolism (SEM) which are related to cycling, resilience, and degree of mutualism, among others. To illustrate the applicability of these methods, we select Samothraki in Greece as a case study. Results show that over the years the island became very efficient in streamlining imported resources, experiencing physical growth as indicated by a substantial increase in its total material throughput. This growth was attributed to a high degree of order (i.e., network efficiency) endowed by the constraining (ordered) part of the linear structure of the islands SEM. The disordered part of its SEM which is related to resilience, played a much smaller role which became progressively more important over the years, albeit to a limited degree. While the island exhibits an increasing trend in its robustness, its value over the years studied was well below what is typically observed for healthy natural ecosystems, and its current SEM has a very low ability to generate internal flow activity and cycling of resources per unit input. This limited robustness is due to the islands dependency on imports but also due to its linear SEM which had a very small number of feedback loops in its network. A scenario analysis showed that a reticulated network structure would theoretically endow the island with increased resilience, and hence robustness, by allowing for more internal resource flow activity to be circulated as regen- erative re-investment. This article highlights that methods from regenerative economics can be used as diagnostic tools to assess and monitor the impact of strategies related to circular economy interventions on network properties, and to illuminate their effect on the regenerative potential of islands.

    How Provider Value is Perceived in regards to Integrated Product Service Offerings and why: A case study2015Independent thesis Advanced level (degree of Master (Two Years)), 20 poäng / 30 hpOppgave
    Abstract [en]

    As companies grow larger and become more international, it is likely that it comes to a point where it would be cheaper to produce on site, or at least have distribution centers, rather than having a centralized production that requires long range shipping. As this occurs, there is a wide range of challenges that the company must face, however these challenges are by now well documented and while not to be underestimated and called “easy” it is nothing new as a wide range of companies have done it before. One aspect that however is less known is the influence that external differences has, in other words factors that would produce a differing result even with the exact same internal setup, on the perceived aspects (referred to as Values in this work) from the providers point of view. In particular what is interesting is the perceived positive impacts above expectations that is gained from having external differences. To be able to better understand and quantify this impact the term “Provider Value” has been created and is being researched towards understanding what Values exist and how they are being affected.Provider Value (PV) is a cutting edge concept within eco-design research that this work is based on and in particular ProVa – Provider Value Evaluation for Integrated Product Service Offerings (Matschewsky et al. 2015) is the latest step to date towards creating the tools needed to increase the utilization, and reap the benefits, of PVs. Another interesting and relevant aspect to PV is how Product/Service System (PSS) could be an essential part in paving a new way of avoiding increased environmental impact while having economic growth. This is done by adding services on top of already existing products (Sakao et al. 2009).To find out more about what kind of external factors that might be behind the differences a case study was conducted, interviewing employees at two companies within one concern in Sweden and Japan. The results of this work indicates that if the company want its PVs to remain the same the main obstacle is external economic differences. In this particular study it is also clear that differences in business model and company structure has a big impact. With all the discussion regarding environment it was on a surprisingly low level of interest at both companies and what mattered was that the products cleared the minimum requirements, nothing more, as “any additional return is hard to estimate”. If PV keeps growing and tools are made to assist, this could not only help simplify the transitioning to other countries and help utilizing existing Values from the start, it could also increase the utilization in general, in particularly in regards to the Environment.

    Public procurement of reconditioned furniture and the potential transition to product service systems solutions2019Konferansepaper (Fagfellevurdert)
    Abstract [en]

    The transition to a circular economy requires the development of new business models. However, ‘circular’ businesses face a number of barriers when competing in the current ‘linear’ economy, and may require the support of public policies. Public procurement may be applied for this purpose, as it can support emerging markets for reconditioned and remanufactured products. Public procurement can also support durable and upgradable products through functional procurement and leasing solutions, thereby promoting product-service systems (PSSs). One product category of high relevance is office furniture, as the purchasing of reconditioned furniture can implicate both environmental and monetary savings for contracting authorities. This study investigates the potential of public procurement to increase the volumes of reconditioned furniture in Sweden and identifies the main drivers and barriers for increasing such practices. The main data collection strategy was semi-structured interviews with furniture reconditioners and public procurement officers. The potential for supporting PSSs through furniture leasing was also analyzed. The main conclusions are that there is significant potential to support furniture reconditioning and PSS solutions through public procurement, especially through the establishment of larger framework contracts and involving furniture manufacturers, but several barriers need to be overcome. Primarily, training and education of public procurers and updating of procurement criteria can facilitate the introduction of reconditioned furniture in purchasing considerations. Moreover, the sector needs to improve its visibility, marketing, and cooperation with public authorities. Finally, functional procurement through PSSs seems unlikely, as it is still quite unclear how the procuring authorities can process the associated contract requirements.

    Managing Innovation Processes for a Business-Driven Collaborative Network to Export Total Technical Solutions2008Inngår i: ISPIM Innovation Symposium, 2008, Singapore: ISPIM , 2008Konferansepaper (Annet vitenskapelig)
    Abstract [en]

    There is a large need of environmental solutions at developing countries, where a network of small firms, e.g. in Sweden, have much opportunity for their business. This paper discusses, from both theoretical and from practical aspects, the high degree of complexity that needs to be managed when small firms export environmental-technology innovation to emerging markets. Especially, it deals with how a network of firms should manage its innovation processes. Based on the review of some 50 literature, the paper explains the methodologies adopted in an on-going project to study these issues. Discussions include differences with development of an integration of products/services within a single firm.

    Kartläggning av en fastighets miljöpåverkan: Livscykelanalys av flerfamiljsfastigheten "Teodoliten"2012Independent thesis Advanced level (degree of Master (Two Years)), 20 poäng / 30 hpOppgave
    Abstract [en]

    Today's climate and environmental issues have now been up for discussion for quite long. Various environmental measures have been taken, but it is not always certain that those measures actually are for the better because of the complexity of our environment. Therefore, studies of whole life cycles are very important even if they are time and resource intensive.

    Real estate accounts for 15% of global carbon emissions, but also affects our environment in many other aspects. In Sweden this number is even higher. About 30 % of its carbon dioxide emissions originates from building sector and changes are therefore of great importance. ByggVesta is a real estate company that wants to be at the forefront when it comes to eco-smart construction and wanted to know how well they are doing. It was therefore desired to conduct this LCA that reviewed their (by February 2012) newest completed property "Teodoliten" in Farsta, Stockholm.

    This life cycle assessment was a screening LCA i.e. it was carried out very superficially in order to identify the biggest polluters. All results were related to the functional unit of 1m2 floor area and year. It was found that the maintenance phase was the most pollutant one because of use of electricity and water. Here it can be mentioned that the electricity consumption is of Swedish electricity mix-type, which is much cleaner than many of the European mixes. It is therefore possible that the results may have been different if Teodoliten had been placed at another location.

    Among all the materials in the property, it was found that concrete elements were the worst pollutants. This report has, however, showed that the longer expected life time, the better this concrete frame is in comparison to wooden frame. If the property will be standing for 100 years, it will emit 95 % of the carbon dioxide- eqv. compared to a wooden frame that stands for only 60 years (the amount that is feasible for a wooden framed house). Although the climate aspect is the most focused one, the other environmental aspects show more clearly the benefits of concrete in long time perspective.

    ByggVesta has also been criticized for their shipments of concrete over the Baltic Sea. However, it has been shown that the transport with a cargo ship corresponds to only 23km by truck. Transport itself is therefore not considered to be a major subject for criticism. Latvian concrete production is of greater interest since the manufacturing process there might differ a lot from Swedish production and have other impact on environment. This issue could not be considered within the scope of this work.

    Shortly, this analysis shows that concrete frames and transportation with cargo ship is preferable if a building like Teodoliten is considered, with its geographical location and if its lifetime will last for 100 years as ByggVesta predicts. However, to be fully sure of the accuracy of these results it might be good to conduct a full comparative LCA on construction materials.
