    Biogas Research Center, BRC: Slutrapport för etapp 12015Rapport (Annet vitenskapelig)
    Abstract [sv]

    Biogas Research Center (BRC) är ett kompetenscentrum för biogasforskning som finansieras av Energimyndigheten, LiU och ett flertal externa organisationer med en tredjedel vardera. BRC har en mycket bred tvärvetenskaplig inriktning och sammanför biogasrelaterad kompetens från flera olika områden för att skapa interaktion på flera olika plan:

    • mellan näringsliv, akademi och samhälle,
    • mellan olika perspektiv, samt
    • mellan olika discipliner och kompetensområden.

    BRC:s vision är:

    Resurseffektiva biogaslösningar finns genomförda i många nya tillämpningar och bidrar till en mer hållbar energiförsörjning, förbättrat miljötillstånd och goda affärer.

    BRC:s särskilda roll för att uppnå denna vision är att bidra med kunskapsförsörjning och process-/teknikutveckling för att facilitera utveckling, innovation och implementering av biogaslösningar. Resurseffektivitet är ett nyckelord, vilket handlar om att förbättra befintliga processer och system samt utveckla biogaslösningar i nya sektorer och möjliggöra användning av nya substrat.

    For BRC:s etapp 1, den första tvåårsperioden mellan 2012-2014, var forskningsprojekten organiserade enligt tabellen nedan. Den visar viktiga utmaningar för biogasproducenter och andra intressenter, samt hur dessa ”angreps” med åtta forskningsprojekt. Fem av projekten var av explorativ karaktär i bemärkelsen att de var bredare och mer framtidsorienterade - exempelvis utvärderade flera möjliga tekniska utvecklingsmöjligheter (EP1-5). Tre projekt hade ett tydligare fokus på teknik- och processutveckling (DP6-8).

    I den här slutrapporten ges en kortfattad bakgrundsbeskrivning och det finns en introduktion till vad den här typen av kompetenscentrum innebär generellt. Därefter finns mer detaljerad information om BRC, exempelvis gäller det centrumets etablering, relevans, vision, hörnstenar och utveckling. De deltagande organisationerna presenteras, både forskargrupperna vid Linköpings universitet och partners och medlemmar. Vidare finns en mer utförlig introduktion till och beskrivning av utmaningarna i tabellen och kortfattat information om forskningsprojekten, följt av ett kapitel som berör måluppfyllelse och den externa utvärdering som gjorts av BRC:s verksamhet. Detaljerad, listad information finns till stor del i bilagorna.

    Kortfattat kan det konstateras att måluppfyllelsen överlag är god. Det är speciellt positivt att så många vetenskapliga artiklar publicerats (eller är på gång att publiceras) kopplat till forskningsprojekten och även i det vidare centrumperspektivet. Helt klart förekommer en omfattande verksamhet inom och kopplat till BRC. I etapp 2 är det viktigt att öka andelen mycket nöjda partner och medlemmar, där nu hälften är nöjda och hälften mycket nöjda. Det handlar framför allt om stärkt kommunikation, interaktion och projektledning. Under 2015 förväntas åtminstone två doktorsexamina, där avhandlingarna har stor koppling till forskningen inom etapp 1.

    I början på år 2014 skedde en extern utvärdering av verksamheten vid BRC med huvudsyftet att bedöma hur väl centrumet lyckats med etableringen samt att granska om det fanns förutsättningar för framtida framgångsrik verksamhet. Generellt var utfallet mycket positivt och utvärderarna konstaterade att BRC på kort tid lyckats etablera en verksamhet som fungerar väl och engagerar det stora flertalet deltagande aktörer, inom relevanta områden och där de flesta involverade ser BRC som en befogad och väl fungerande satsning, som de har för avsikt att även fortsättningsvis stödja. Utvärderingen bidrog också med flera relevant tips och till att belysa utmaningar.

    Utöver denna slutrapport finns separata publikationer från forskningsprojekten.

    Arbetet som presenteras i rapporten har finansierats av Energimyndigheten och de medverkande organisationerna.

    Industrial ecology looks at landfills from another perspective2011Inngår i: Regional Development Dialogue, ISSN 0250-6505, Vol. 31, nr 2, s. 169-182Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The objective of this article is to go beyond the currently established view on landfills as final deposits for waste and analyse their potential as future resource reservoirs. We analyse whether the application of the industrial ecology concept can contribute in realising the approach of landfill mining as an alternative strategy for extraction of valuable material and energy resources. In doing so, an analytical approach involving three main steps was applied. Firstly, state-of-the-art research on landfill mining is reviewed in order to identify critical barriers for why this promising approach not yet has been fully realised. Then, some of the main constituents of industrial ecology research were briefly summarised with special emphasis on how they relate to landfills. The third and final step involved a synthesis aiming to conclude in what way industrial ecology could contribute in addressing the identified challenges for implementation of landfill mining. We conclude the systems view of industrial ecology provides both a comprehensive view on environmental potential and impacts as well as new public/private partnerships for landfill mining activities for mutual benefits.

    A Critical Review of the Sustainability of Multi-Utility Tunnels for Colocation of Subsurface Infrastructure2022Inngår i: Frontiers in Sustainable Cities, E-ISSN 2624-9634, Vol. 4, artikkel-id 847819Artikkel, forskningsoversikt (Fagfellevurdert)
    Abstract [en]

    Multi-utility tunnel (MUT) have received increasing attention as an alternative method for installing subsurface infrastructure for the distribution of electricity, telecommunications, water, sewage and district heating. MUTs are described as a potentially more sustainable technology than conventional open-cut excavation (OCE), especially if the entire life cycle of these cable and pipe networks is taken into account. Based on an extensive review of the academic literature, this article aims to identify and critically examine claims made about the pros and cons of using MUT for the placement of subsurface infrastructure. Identified claims are mapped, and their validity and applicability assessed. These claims are then analyzed from a sustainability perspective, based on the three sustainability dimensions and a life cycle perspective. The results show that a variety of advantages and disadvantages of using MUTs for subsurface infrastructure are highlighted by the articles, but several of these are without any empirical support. When some form of empirical support is presented, it usually comes from case-specific analyses of MUTs, and the applicability in other MUT projects is seldom discussed. Economic performance is the sustainability dimension that has received the most attention, while environmental performance has not been analyzed in the reviewed literature, which is a major limitation of the current knowledge. In summary, the knowledge about the sustainability performance of using MUTs for subsurface infrastructure is still limited and incoherent. In order to increase the knowledge, this article points out the importance of new case studies, in which the sustainability consequences of using MUTs for subsurface infrastructure are mapped and evaluated by combining both quantitative and qualitative assessment methods.

    What should we do with CO₂ from biogas upgrading?2023Inngår i: Journal of CO2 Utilization, ISSN 2212-9820, E-ISSN 2212-9839, Vol. 77, artikkel-id 102607Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Carbon capture and utilization has been proposed as an essential climate change mitigation strategy, but only a few implemented cases exist. During biomethane production from anaerobic digestion, CO₂ is commonly separated and emitted into the atmosphere, which can be utilized as raw material for various products. This research aims to identify and assess CO₂ utilization alternatives for possible integration with biogas upgrading from anaerobic digestion by developing a soft multi-criteria analysis (MCA). A literature review complemented with stakeholder participation enabled the identification of relevant alternatives and criteria for assessment. Potential alternatives for CO₂ utilization include methane, mineral carbonates, biomass production, fuels, chemicals, pH control, and liquefied CO₂. Results show that although no alternative performs well in all indicators, there is an opportunity for short-term implementation for methane, biomass production, mineral carbonates, liquefied CO₂, and pH control. Moreover, the uncertainty analysis reveals that even though the technologies have a high technological development, more information on critical aspects is still required. The soft MCA provides information to decision-makers, practitioners, and the academic community on learning opportunities of the alternatives and indicators to step from development into implementation. For instance, the method can be used to assess more specific systems with different locations and scales or to direct efforts to ease the implementation of CCU.

    Is enhanced landfill mining profitable?2018Inngår i: ISWA 2018 Book of Proceedings, 2018, s. 240-245Konferansepaper (Annet vitenskapelig)
    Abstract [en]

    The shift from linear to circular economy has steered the change in perception about landfills. From final to temporary waste storage, landfills are considered as technospheric stocks of resources that can be recovered through innovative technologies in the concept of enhanced landfill mining (ELFM). At present, most ELFM projects are in pilot-scale and it remains as a proof of concept. Economic feasibility is one of the primary considerations that must be satisfied prior to its full-scale realization. Several economic assessments were conducted in recent years but there is no systematic synthesis of these studies to date. The aim of this review is to compile various empirical insights of previous economic assessments of ELFM in relation to the employed methodological choices. With pre-defined exclusion criteria, 15 studies were selected in this review. For the empirical part, the identified main economic drivers for costs are separation and sorting, thermal treatment and transportation, while for benefits are material sales, recovered land and energy sales. In more than half of the studies, the costs exceeded the benefits concluding that ELFM is not profitable.  The few potentially profitable cases mainly depend on varying the system conditions defined by market prices and regulations. These require changes that are more radical, if not impossible. For the method part, costs and benefits are accounted at different levels of aggregation, scope and scale—that is from process to sub-process level, from private to societal economics, and from laboratory to pilot scale, respectively. As most studies are based on pilot scale, if not purely conceptual, data estimation mainly depends on extrapolation from these pilot projects or on direct adoption of secondary data. In spite of the expected uncertainties in model, scenario and parameter, less than half of the studies employed sensitivity and uncertainty analyses. With it being neglected, their results can be considered to have a weak reliability for practical use in a full-scale ELFM project implementation. A need for systematic framework for early-stage assessment is highlighted to capture both stochastic and epistemic uncertainties. Process and system upscaling with exploratory scenario development, and participatory data collection in ranges rather than in absolute terms are some of the suggested approaches to generate results with a certain level of confidence. In this way, the future economic assessments of ELFM can veer away from simple profitability assessments. Instead, it focuses on knowledge development despite the limited information that is inherent to emerging concepts. Most importantly, it provides reliable information that can be used as a decision-support for various stakeholders such as project managers, technology developers, and policy makers towards the advancement of ELFM.

    The economic and environmental performance of a landfill mining project from the viewpoint of an industrial landfill owner2018Inngår i: Proceedings of the 4th International Symposium on Enhanced Landfill Mining, 5-6 February, 2018, Mechelen, Belgium / [ed] Peter Tom Jones and Lieven Machiels, Leuven, Belgium: University of Leuven , 2018, s. 389-396Konferansepaper (Fagfellevurdert)
    Abstract [en]

    The EU Commission’s circular economy strategy pushes for a higher recycling rate and a more long-term waste management practice.1 Enhanced Landfill Mining (ELFM) can contribute to this agenda as a better landfill management option, by shifting the landfill paradigm from dumping or as end-storage of waste to resource recovery or as temporary storage of resources.2-4 Through ELFM, landfills becomes a secondary source of both material (Waste-to-Material, WtM) and energy (Waste-to-Energy, WtE) with the use of innovative technologies.3,4

    Several studies explored the environmental and/or economic aspects of ELFM having different scopes and objectives. Some cover the entire process value chain while others additionally focused on comparing technological choices for WtE,5–7 WtM,8,9 and even ELFM waste valorisation.10 Furthermore, for the economic assessment, regulation-related costs and benefits as landfill taxes, gate fees and green certificates5,11,12 are also accounted for. Regarding the identification of economic hotspots, many of these studies concluded similar processes to be important. However, most of these studies were based on either hypothetical cases, or real cases but with small-scale excavation and separation using non-sophisticated set-ups, which are not likely to be used for large-scale processing. Hence, more uncertainty is expected from the lack of actual ELFM demonstration projects.

    The aim of this study is to analyse the main contributing factors that influence environmental and economic performance of ELFM, considering the landfill owner’s viewpoint. The study is based on a real case of excavation and subsequent separation in an existing stationary facility. Specifically, the influence of the prevailing system conditions is investigated as defined by the current legislation and the market situation.

    Life-Cycle Assessment and Uncertainty Analysis of Producing Biogas from Food Waste: A Case-Study of the First Dry-Process Biogas Plant in SwedenManuskript (preprint) (Annet vitenskapelig)
    Abstract [en]

    Anaerobic digestion of source-sorted food waste is increasing in Sweden. Traditionally, all large-scale co-digestion plants in Sweden, including the ones which digest food waste, are based on wet process. In this article life-cycle assessment (LCA) is used in order to investigate the environmental performance of the first dry-process biogas plant based on source-sorted municipal food waste in Sweden. The environmental performance of this plant is compared with existing typical plants which are based on wet process. Biogas production systems are complex, and there are knowledge gaps and large uncertainties regarding some of the processes. Most existing biogas LCA studies do not take into account these uncertainties and use single values in their life-cycle inventories. In this study uncertainty propagation in LCA of biogas production system is performed and the results are discussed in order to gain system-level insights on the main factors that influence the performance of producing biogas from food waste and the key uncertainties. An attributional process-based LCA model is used to study the global warming potential, eutrophication potential, acidification potential, and non-renewable cumulative energy demand of producing biogas from food waste. A reference case is used which is based on an actual biogas plant in Sweden which uses dry process for treating source-sorted food waste. For the wet process, this case is altered using Swedish literature data on wet digestion systems. For uncertainty management, a combination of approaches, including possibility/fuzzy intervals and stochastic distributions are used. Possibility/fuzzy intervals are used for data collection, but they are translated into probability distributions and Monte Carlo simulation. A simple method for quantifying the uncertainties of the LCA results is used, so the critical uncertainties can be assessed, compared, and discussed. In addition, several key performance indicators were introduced to complement the LCA results.The results of the LCA and KPIs show that using dry process for processing of food waste has a better or comparable environmental performance compared to most existing (wet-process) biogas plants in Sweden. When uncertainties are considered, two systems are more comparable. Regardless of the choice of wet or dry process for treatment of food waste, there are large uncertainties in the non-technical parts of the system which are less dependent to the technical choices or scenario assumptions. Decision-makers who are interested in using biogas systems for treatment of source sorted food waste, should take dry process into consideration. From an energy and environmental perspective, dry process can have good or better performance compared to many existing plants which are based on the wet process. This is mainly due to simpler pretreatment and digestate management. Taking into account the uncertainties (knowledge gaps, and variabilities) in assessing and comparing the performance of biogas production from food waste, provides a more realistic picture of their strengths and weaknesses. Since some of the impacts (and benefits such as carbon sequestration) of using food waste for biogas production and its digestate as biofertilizer lies in areas with high uncertainties, communication of these benefits to wider socio-political actors can play an important role for the development of biogas from food waste in Sweden, because many of the benefits of biogas solutions are not visible when analyzed by LCA approaches that do not take into account these uncertainties.

    Integrating remediation and resource recovery: On the economic conditions of landfill mining2015Inngår i: Waste Management, ISSN 0956-053X, E-ISSN 1879-2456, Vol. 42, s. 137-147Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    This article analyzes the economic potential of integrating material separation and resource recovery into a landfill remediation project, and discusses the result and the largest impact factors. The analysis is done using a direct costs/revenues approach and the stochastic uncertainties are handled using Monte Carlo simulation.

    Two remediation scenarios are applied to a hypothetical landfill. One scenario includes only remediation, while the second scenario adds resource recovery to the remediation project. Moreover, the second scenario is divided into two cases, case A and B. In case A, the landfill tax needs to be paid for re-deposited material and the landfill holder does not own a combined heat and power plant (CHP), which leads to disposal costs in the form of gate fees. In case B, the landfill tax is waived on the re-deposited material and the landfill holder owns its own CHP.

    Results show that the remediation project in the first scenario costs about €23/ton. Adding resource recovery as in case A worsens the result to −€36/ton, while for case B the result improves to −€14/ton. This shows the importance of landfill tax and the access to a CHP. Other important factors for the result are the material composition in the landfill, the efficiency of the separation technology used, and the price of the saleable material.

    A novel approach for environmental evaluation of landfill mining2013Inngår i: Journal of Cleaner Production, ISSN 0959-6526, E-ISSN 1879-1786, Vol. 55, s. 24-34Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Studies concerning landfill mining have historically focused on reclamation of land space and landfill remediation. A limited number of studies, however, have evaluated landfill mining combined with resource recovery, most of them being pilot studies or projects with little emphasis on resource extraction. This implies that many uncertainties remain related to landfill mining. With a growing interest in environmental concerns around the globe, the environmental evaluation of large-scale projects has become an increasingly important issue. A common way of conducting such an evaluation is to use Life Cycle Assessment (LCA). However, LCA by itself might not take into account all the inherent uncertainties in landfill mining. This article describes an approach for environmental evaluation of landfill mining that combines the principles of Life Cycle Assessment and Monte Carlo Simulation. In order to demonstrate its usability for planning and evaluation purposes, the approach is also applied to a hypothetical landfill mining case by presenting examples of the types of results it can produce. Results from this approach are presented as cumulative probability distributions, rather than a single result figure. By presenting results in this way, the landfill mining practitioner will get a more complete view of the processes involved and will have a better decision base.

    Resource and Climate Implications of Landfill Mining A Case Study of Sweden2013Inngår i: Journal of Industrial Ecology, ISSN 1088-1980, E-ISSN 1530-9290, Vol. 17, nr 5, s. 742-755Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    This study analyzes the amount of material deposited in Swedish municipal solid waste landfills, how much is extractable and recyclable, and what the resource and climate implications are if landfill mining coupled with resource recovery were to be implemented in Sweden. The analysis is based on two scenarios with different conventional separation technologies, one scenario using a mobile separation plant and the other using a more advanced stationary separation plant. Further, the approach uses Monte Carlo simulation to address the uncertainties attached to each of the different processes in the scenarios. Results show that Swedens several thousand municipal landfills contain more than 350 million tonnes (t) of material. If landfill mining combined with resource recovery is implemented using a contemporary stationary separation plant, it would be possible to extract about 7 million t of ferrous metals and 2 million t of nonferrous metals, enough to meet the demand of Swedish industry for ferrous and nonferrous metals for three and eight years, respectively. This study further shows that landfill mining could potentially lead to the equivalent of a one-time reduction of about 50 million t of greenhouse gas emissions (carbon-dioxide equivalents), corresponding to 75% of Swedens annual emissions.

    Scenarios for upgrading and distribution of compressed and liquefied biogas: Energy, environmental, and economic analysis2020Inngår i: Journal of Cleaner Production, ISSN 0959-6526, E-ISSN 1879-1786, Vol. 256, artikkel-id 120473Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    In the transition towards fossil-free transports, there is an increasing interest in upgraded biogas, or biomethane, as a vehicle fuel. Liquefied biogas has more than twice as high energy density as compressed biogas, which opens up the opportunity for use in heavy transports and shipping and for more efficient distribution. There are several ways to produce and distribute compressed and liquefied biogas, but very few studies comparing them and providing an overview. This paper investigates the energy balance, environmental impact and economic aspects of different technologies for upgrading, liquefaction and distribution of biogas for use as a vehicle fuel. Furthermore, liquefaction is studied as a method for efficient long-distance distribution.

    The results show that the differences between existing technologies for upgrading and liquefaction are small in a well-to-tank perspective, especially if the gas is transported over a long distance before use. Regarding distribution, liquefaction can pay back economically after 25–250 km compared to steel container trailers with compressed gas, and reduce the climate change impact after 10–30 km. Distribution in gas grid is better in all aspects, given that it is available and no addition of propane is required. Liquefaction can potentially expand the geographical boundaries of the market for biogas as a vehicle fuel, and cost reductions resulting from technology maturity allow cost-effective liquefaction even at small production capacities.

    Technologies for production of liquefied biogas for heavy transports: Energy, environmental, and economic analysis2019Konferansepaper (Fagfellevurdert)
    Abstract [en]

    The heavy transport sector is facing a growth within technology and infrastructure for use of natural gas. This opens an opportunity for the biogas market to grow as well, especially in the form of liquefied biogas (LBG). This study presents an investigation of the energy balance, environmental impact and economic aspects of current technologies for production of LBG: mixed refrigerant cycle, nitrogen cycle, pressure reduction and cryogenic liquefaction. Calculations are based on a review of recent literature and data from the biogas industry. The results show that mixed refrigerant cycle is the most economic and energy efficient technology for liquefaction of upgraded biogas, followed by nitrogen cycle. The lowest electricity use and environmental impact is achieved if the liquefaction process is preceded by amine scrubber upgrading. Pressure reduction liquefaction is inexpensive and can be an alternative in areas connected to a high-pressure gas grid, but as a method for liquefaction it is not very efficient as only about 10% of the incoming gas is liquefied and the rest remains in its gaseous form. Moreover, addition of propane for distribution in the natural gas grid increases the environmental impact compared to other distribution pathways. The cryogenic technology has a higher energy use than other liquefaction technologies but compensates by also including CO₂ separation, which could make it suitable if there is no existing upgrading facility in place. However, there are technical difficulties to overcome and it is not widely implemented.

    Cleaner heavy transports: Environmental and economic analysis of liquefied natural gas and biomethane2021Inngår i: Journal of Cleaner Production, ISSN 0959-6526, E-ISSN 1879-1786, Vol. 278, artikkel-id 123535Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Looking to reduce climate change impact and particle emissions, the heavy-duty transport sector is moving towards a growth within technology and infrastructure for use of liquefied natural gas (LNG). This opens an opportunity for the biogas market to grow as well, especially in the form of liquefied biomethane (LBM). However, there is a need to investigate the economic conditions and the possible environmental benefits of using LBM rather than LNG or diesel in heavy transports. This study presents a comparison of well-to-wheel scenarios for production, distribution and use of LBM, LNG and diesel, assessing both environmental and economic aspects in a life cycle perspective. The results show that while LNG can increase the climate change impact compared to diesel by up to 10%, LBM can greatly reduce the environmental impact compared to both LNG and diesel. With a German electricity mix, the climate change impact can be reduced by 45 – 70% compared to diesel with LBM from manure, and by 50 – 75% with LBM from food waste. If digestate is used to replace mineral fertilizer, the impact of LBM can even be less than 0. However, the results vary a lot depending on the type of feedstock, the electricity system and whether the calculations are done according to RED or ISO guidelines. Economically, it can be hard for LBM to compete with LNG, due to relatively high production costs, and some form of economic incentives are likely required.

    Energy performance indicators as policy support for public bus transport: The case of Sweden2018Inngår i: Transportation Research Part D: Transport and Environment, ISSN 1361-9209, E-ISSN 1879-2340, Vol. 65, s. 697-709Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The share of renewable fuels in Swedish public transport is steadily increasing, in line with European energy and climate goals as well as a national goal of a fossil-free vehicle fleet by 2030. However, the progression towards this goal is quite different among the Swedish regions, and efforts have been made on a national level to compare the public bus transport systems and provide a foundation for policymaking. This paper investigates different ways of assessing and presenting the energy performance of public bus transport systems. The analysis includes use of renewable and fossil fuels as well as energy efficiency and its underlying factors. Various energy performance indicators are presented and discussed with regards to practical implications and applicability for policy support.

    A life cycle perspective on fuels (“well-to-wheel”) is found to have clear advantages when it comes to global reductions of fossil energy use and emissions. This requires detailed information about the fuel use, which is not always the case with the existing reporting system. Setting the energy use in relation to number of passengers transported rather than just the distance covered would better reflect the function of the transport system, but is also more uncertain with the current data available.

    Well-to-wheel greenhouse gas emissions of heavy-duty transports: Influence of electricity carbon intensity2021Inngår i: Transportation Research Part D: Transport and Environment, ISSN 1361-9209, E-ISSN 1879-2340, Vol. 93Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    There are several alternatives for how to phase out diesel in heavy-duty transports, thereby reducing the sector’s climate change impact. This paper assesses the well-to-wheel (WTW) greenhouse gas (GHG) emissions of energy carriers for heavy-duty vehicles, analyzing the effect of the carbon intensity of the electricity used in production. The results show that energy carriers with high electricity dependence are not necessarily better than diesel from a WTW perspective. In particular, fuels produced through electrolysis are not well suited in carbon-intense electricity systems. Conversely, waste-based biofuels have low GHG emissions regardless of the electricity system. Battery-electric buses show a large reduction of GHG emissions compared to diesel buses and many other alternatives, while battery-electric trucks have higher GHG emissions than diesel in carbon intense electricity systems. Thus, electrifying transports or switching to renewable fuels will not suffice if the electricity system is not made renewable first.

    Well-to-wheel climate performance of gas and electric vehicles in Europe2021Inngår i: Transportation Research Part D: Transport and Environment, ISSN 1361-9209, E-ISSN 1879-2340, Vol. 97, artikkel-id 102911Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Focusing on tailpipe emissions, current EU policies do not favor the use of biofuels in transports. This paper analyzes the well-to-wheel climate performance of gas and electric vehicles in Europe, taking into account the share of biomethane in vehicle gas as well as the production systems for biomethane and electricity in different countries. The results show that both gas and electric vehicles can significantly reduce the climate change impact of transports compared to diesel. In an average European electricity system, electricity has around 30% lower climate impact than diesel for a heavy truck, and 65-70% lower for a passenger car or city bus. Average European vehicle gas reduces the climate impact by up to 28% compared to diesel, or 11% compared to fossil natural gas, and in some countries vehicle gas has lower climate impact than electricity. This demonstrates the importance of not limiting analysis and policy to tailpipe emissions.

    The role of biogas solutions in sustainable biorefineries2018Inngår i: Journal of Cleaner Production, ISSN 0959-6526, E-ISSN 1879-1786, Vol. 172, s. 3982-3989Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Biorefineries strive to maximise product mix and value while contributing to the bioeconomy. Circularityand waste valorisation are some important but often neglected concepts in this context. As such, biogassolutions in biorefineries could be a key technology to improve sustainability. This study has, through aliterature review and investigation into three Swedish case studies, analysed this relationship betweenbiogas solutions and biorefineries by assessing the added value and development potential to whichbiogas solutions may contribute. This analysis across agricultural, forest, and marine sectors indicatesthat biogas solutions contribute with several added values, including through making the biorefinerymore sustainable and competitive. The study also shows that biogas solutions can be an enabler ofbiorefinery development through making the system more resilient and versatile, as well as throughimproving the value of the product portfolio.

    Assessment of By-product Valorisation in a Swedish Wheat-Based Biorefinery2020Inngår i: Waste and Biomass Valorization, ISSN 1877-2641, E-ISSN 1877-265X, Vol. 11, nr 7, s. 3567-3577Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Biorefineries are examples of industries striving towards a circular and bio-based economy through valorising natural raw materials to a spectrum of products. This is a resource-efficient process which also decreases overall environmental impact, as the products from a biorefinery can replace fossil-based products such as plastics or fuels. To become even more resource efficient, an optimisation of the by-product use can increase the performance. This study will evaluate different scenarios for the valorisation of stillage coming from a wheat-based biorefinery. The alternatives range from the direct use of the stillage for fodder, fertiliser or incineration to three different biogas production-based scenarios. The biogas scenarios are divided into the production of fuel at a local or distant plant and the alternative of creating heat and power at the local plant. The results show how locally produced biogas for vehicle fuel and fodder usage are the better alternatives regarding greenhouse gas emissions, the finances of the biorefinery, energy balance and nutrient recycling. The results also indicate that biorefineries with several high-value products may receive lower quality by-product flows, and to these, the biogas solutions become more relevant for valorising stillage while improving value and performance for the biorefinery.

    Integration of resource recovery into current waste management through (enhanced) landfill mining2019Inngår i: Detritus, ISSN 2611-4135, Vol. 08, s. 141-156Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Europe has somewhere between 150,000 and 500,000 landfill sites, with an estimated 90% of them being “non-sanitary” landfills, predating the EU Landfill Directive of1999/31/EC. These older landfills tend to be filled with municipal solid waste andoften lack any environmental protection technology. “Doing nothing”, state-of-theart aftercare or remediating them depends largely on technical, societal and economic conditions which vary between countries. Beside “doing nothing” and landfill aftercare, there are different scenarios in landfill mining, from re-landfilling thewaste into “sanitary landfills” to seizing the opportunity for a combined resource-recovery and remediation strategy. This review article addresses present and futureissues and potential opportunities for landfill mining as an embedded strategy incurrent waste management systems through a multi-disciplinary approach. In particular, three general landfill mining strategies are addressed with varying extentsof resource recovery. These are discussed in relation to the main targets of landfill mining: (i) reduction of the landfill volume (technical), (ii) reduction of risks andimpacts (environmental) and (iii) increase in resource recovery and overall profitability (economic). Geophysical methods could be used to determine the characteristics of the landfilled waste and subsurface structures without the need of aninvasive exploration, which could greatly reduce exploration costs and time, aswell as be useful to develop a procedure to either discard or select the most appropriate sites for (E)LFM. Material and energy recovery from landfilled waste canbe achieved through mechanical processing coupled with thermochemical valorization technologies and residues upcycling techniques. Gasification could enablethe upcycling of residues after thermal treatment into a new range of eco-friendlyconstruction materials based on inorganic polymers and glass-ceramics. The multi-criteria assessment is directly influenced by waste- and technology related factors, which together with site-specific conditions, market and regulatory aspects,influence the environmental, economic and societal impacts of (E)LFM projects.

    Urban mining - Prospecting for metals in the invisible city2010Inngår i: Knowledge Collaboration & Learning for Sustainable Innovation, ERSCP-EMSU conference, Delft, The Netherlands, October 25-29, 2010, 2010Konferansepaper (Fagfellevurdert)
    Abstract [en]

    In theory, ‘urban mining’ has a huge potential for enabling more efficient resource use and offering new business opportunities for the cleantech and recycling industries. This concept involves recovering technospheric stocks of previously employed natural resources that have been taken out of use without being collected for waste management. Such hibernating material stocks can be found in old water supply, sewage and power distribution networks – urban structures rich in for example iron and copper. This paper aims to analyze the potential for urban mining of the metals copper and aluminum from hibernating power and communication cables in Sweden. Emphasis is on the economic feasibility of two different approaches for realizing such initiatives. The results indicate that separate extraction of obsolete cables situated below ground in a city is not yet likely to be economically justified for power grid managers. Even in case of integrated recovery during other maintenance work on the grids, additional project costs often exceed potential revenues for the cables. In rural areas, however, both separate and integrated recovery of hibernating cables seem straightforwardly profitable, especially for obsolete copper cables belonging to the regional communication network. It is concluded however that the viability of urban mining is not only a matter of economics. Research aiming to analyze technical, economic, environmental and other institutional conditions for realization of urban mining is therefore strongly encouraged.

    Urban mining: hibernating copper stocks in local power grids2011Inngår i: Journal of Cleaner Production, ISSN 0959-6526, E-ISSN 1879-1786, Vol. 19, nr 9-10, s. 1052-1056Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Large technical systems serving the everyday needs of people, such as water supply systems, power gridsor communication networks, are rich in accumulated metals. Over time, parts of these systems have beentaken out of use without the system infrastructure being removed from its original location. Such metalstocks in hibernation thus constitute potential resource reservoirs accessible for recovery. In this paper,obsolete stocks of copper situated in the local power grids of two Swedish cities are quantified. Emphasisis also on economic conditions for extracting such “hibernating” cables. The results show that on a percustomer basis, the two power grids contain similar amounts of copper, i.e. 0.04e0.05 tonnes persubscriber. However, the share of the copper stock that is in hibernation differs between the grids. In thelarger grid of Gothenburg, almost 20% of the copper accumulated in the grid is no longer in use, while theobsolete share does not exceed 5% in the city of Linköping. For managers of local power grids, recovery ofhibernating cables could be beneficial if integrated with other maintenance work on the grid. At thepresent price of copper, however, separate recovery of obsolete cables is not economically justified.

    Environmental and economic conditions for landfill mining2009Inngår i: 2009 ISIE Conference: 5th International Conference on Industrial Ecology: Transition Towards Sustainability, 2009, s. 189-Konferansepaper (Annet vitenskapelig)
    Abstract [en]

    "At the conference we would like to present selected results from an ongoing research project

    aiming to address the environmental and economic potentials of landfill mining (LFM) in Sweden. LFM means the excavation processing treatment or recycling of waste that over the years have been dumped in waste deposits. In the first part of the presentation the environmental potential of LFM on the national scale of Sweden will be quantified in terms of selected impact categories (global warming potential material and energy resource flows etc.). Preliminary results show that this overall potential is huge and could for instance lead to avoided climate gas emissions corresponding to 4–5 times the annual Swedish emissions. Critical factors (efficiency of waste technology transportation distances etc.) determining to what extent such potentials can be realised in practice i.e. in specific LFM–projects will then be discussed. The second and final part of the presentation will solely focus on conditions for realisation. Here we will discuss under what circumstances LFM is profitable and contributes to economic growth. Our ongoing research show that only the raw material value of Swedish waste deposits is beyond 10 billion Euros (€). However no matter how large the economic potential appears on the national scale the realisation of LFM will always be done by actors on the project level. For these individual companies benefits must simply outweigh the costs. There are however many factors that may influence the profitability of specific projects such as revenues for recovered materials efficiency of technology environmental taxes and waste disposal fees labour regulatory compliance expenses and so on. We will categorise such factors into a few critical drivers enablers and barriers for implementation of LFM and discuss them in terms of technology legislation and market interactions."

    Landfill mining: A critical review of two decades of research2012Inngår i: Waste Management, ISSN 0956-053X, E-ISSN 1879-2456, Vol. 32, nr 3, s. 513-520Artikkel, forskningsoversikt (Fagfellevurdert)
    Abstract [en]

    Landfills have historically been seen as the ultimate solution for storing waste at minimum cost. It is nowa well-known fact that such deposits have related implications such as long-term methane emissions,local pollution concerns, settling issues and limitations on urban development. Landfill mining has beensuggested as a strategy to address such problems, and in principle means the excavation, processing,treatment and/or recycling of deposited materials. This study involves a literature review on landfill miningcovering a meta-analysis of the main trends, objectives, topics and findings in 39 research paperspublished during the period 1988–2008. The results show that, so far, landfill mining has primarily beenseen as a way to solve traditional management issues related to landfills such as lack of landfill space andlocal pollution concerns. Although most initiatives have involved some recovery of deposited resources,mainly cover soil and in some cases waste fuel, recycling efforts have often been largely secondary.

    Landfill mining: a review of three decades of research2010Inngår i: Knowledge Collaboration & Learning for Sustainable Innovation, ERSCP-EMSU conference, Delft, The Netherlands, October 25-29, 2010, 2010Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Landfills have historically been seen as the ultimate solution for storing waste at minimum cost. It is now a well-established fact however that such deposits have related implications such as long-term methane emissions, local pollution concerns and limitations on urban development. Landfill mining has been suggested as a strategy to address such resource and pollution problems and in principle means the excavation, processing, treatment and/or recycling of deposited materials. This study involves a literature review on landfill mining covering an analysis of trends, objectives and research topics in 39 papers published during the period 1988–2008. The results show that so far landfill mining has primarily been seen as a way to solve traditional waste management issues such as lack of landfill space or facilitation of final closure and remediation of waste deposits. Although most initiatives also have involved some effort to recover deposited resources (primarily cover soil material), such constituents have been largely secondary. Typically, simple soil excavation and screening equipment have therefore been applied, often demonstrating moderate performance in obtaining marketable recyclables. Several worldwide changes and recent research findings however indicate the emergence of a new perspective on landfills as future reservoirs for resource extraction. Although the potential of this approach appears gigantic, it is argued that facilitating implementation also involves a number of challenges in terms of technology innovation, concepts for realization and frameworks for evaluating economic and environmental performance.

    Potential metal resources in waste incineration ash deposits2012Inngår i: SUM 2012 Symposium on Urban Mining, 2012Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Incineration of waste has always been connected to large metal flows, and it has long been a concern from an environmental point of view, with special focus given to high metal concentrations in the flue gas. However, these metal flows could have also been seen as a potential resource stock available for extraction. This study aims to assess the potential of Swedish waste incineration ash deposits as sources for metal extraction. A second, and equally important aim, is to contribute knowledge for priority-setting of future research on metal extraction methods from such residues.

     

    The results from this study indicate that the metal flows are still considerable. The total amounts of scrap metal in these deposits are significant, and nearly amount to the annual collection of both ferrous and non-ferrous scrap in Sweden. Furthermore, for some of the metals studied the annual flows in Sweden seem to be higher than the metal flows in slag from the copper and steel industries. The main research regarding the extraction of metals from MSWI ash has focused on fly ash. However, by looking at the total potential amounts in different deposits, the results in this study suggest that, from an environmental and economic point of view, the highest potential seems to be for metal stocks in the bottom ash. One metal that has not been high on the research agenda is Titanium, which, due to a high raw material value combined with large amounts in deposits, is ranked at the top from both the economic and environmental perspectives. The results also show that there currently seems to be less incentive to extract the scarcer metals both from an economic and an environmental point of view.

    The article gives suggestions for future research. For example, how much of the metals in the deposits are in a chemical form, making them suitable for extraction? Which challenges arise if the focus of extraction is turned towards the bottom ashes, with their lower concentrations but higher total amounts? Furthermore, research is needed on how accessible different types of deposits are, and what type of institutional and technological challenges and possibilities would arise in a real-world extraction activity.

    How to evaluate (enhanced) landfill mining: A critical review of recent environmental and economic assessments2018Inngår i: Proceedings of the 4th International Symposium on Enhanced Landfill Mining, 2018 / [ed] Peter Tom Jones and Lieven Machiels, Leuven: KU Leuven , 2018, s. 317-332Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Landfill mining has been proclaimed as an alternative strategy to address unwanted impacts of waste deposits. In real-life projects, such excavation and processing of deposited waste has mainly been used to facilitate traditional objectives such as remediation, land reclamation or creation of landfill airspace. A key target of recent landfill mining research is, however, to go beyond this type of local motives and enhance the recovery of materials and energy resources by developing advanced processing technologies. Although such an ambitiousapproach clearly displays a wider societal potential, it also adds complexity to the implementation and assessment of pros and cons of landfill mining.

    Urban infrastructure mines: on the economic and environmental motives of cable recovery from subsurface power grids2015Inngår i: Journal of Cleaner Production, ISSN 0959-6526, E-ISSN 1879-1786, Vol. 104, s. 353-363Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Subsurface power grids constitute one of the largest copper stocks in many industrialized cities. Over time, parts and zones of these systems have been continuously disconnected and abandoned, resulting in the emergence of urban infrastructure ores. This study aims to assess how current conditions and practices influence economic and environmental motives of cable recovery from such power grids. By applying an infrastructure managers perspective and evaluating 16 scenarios involving different extraction technologies and procedures, surface materials, urban locations and types of cables, we identify key areas where solutions or changes to increase incentives for cable recovery are needed. The assessed scenarios display significantly different cable extraction costs, where excavation in city centers with asphalt or cobblestone pavements generates the highest costs while greenbelts offer the best conditions. In most cases, cable revenues are not even close to outweighing the extraction costs. This is especially true for paper-coated cables or cables with aluminum conductors, for which the revenues are much lower than for plastic-insulated copper cables. Although economic conditions could be improved by integrating cable recovery to regular system upgrade projects or by applying non-digging technologies, clear incentives rely on the cable in question being especially valuable. Most of the cable recovery scenarios display environmental motives in terms of net savings in GHG emissions due to metal recycling. In contrast to the economic results, recycling of aluminum power cables is here more awarding than that of corresponding copper cables. We conclude that under current conditions urban mining does not make economic sense to infrastructure managers unless it is integrated as an added value to system upgrade projects. Apart from such re-arrangements in infrastructure provision, several other practice-related changes to cut cable extraction costs are possibly within reach for the managers. Still, an economically motivated practice relies on several external performance drivers such as market diffusion of non-digging technologies, improved cable recycling processes, and increased scrap metal prices. Our conclusion that the arguments for urban mining are currently more environmental than financial, points towards changed perspectives where such activities are seen as a way for infrastructure managers to contribute to societal goals such as climate change mitigation and reduced mineral resource dependence.

    Quantitative Analysis of Critical Factors for the Climate Impact of Landfill Mining2016Inngår i: Environmental Science and Technology, ISSN 0013-936X, E-ISSN 1520-5851, Vol. 50, nr 13, s. 6882-6891Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Landfill mining has been proposed as an innovative strategy to mitigate environmental risks associated with landfills, to recover secondary raw materials and energy from the deposited waste, and to enable high-valued land uses at the site. The present study quantitatively assesses the importance of specific factors and conditions for the net contribution of landfill mining to global warming using a novel, set-based modeling approach and provides policy recommendations for facilitating the development of projects contributing to global warming mitigation. Building on life-cycle assessment, scenario modeling and sensitivity analysis methods are used to identify critical factors for the climate impact of landfill mining. The net contributions to global warming of the scenarios range from -1550 (saving) to 640 (burden) kg CO(2)e per Mg of excavated waste. Nearly 90% of the results total variation can be explained by changes in four factors, namely the landfill gas management in the reference case (i.e., alternative to mining the landfill), the background energy system, the composition of the excavated waste, and the applied waste-to-energy technology. Based on the analyses, circumstances under which landfill mining should be prioritized or not are identified and sensitive parameters for the climate impact assessment of landfill mining are highlighted.

    Life cycle assessment of floor care: A comparative study of the Twister™ method and floor care methods using polish and wax2009Rapport (Annet vitenskapelig)
    Abstract [en]

    In Today’s society there are a wide variety of floor and floor materials. An extensive range of products and methods are also used to ensure that these floors remain functional. All floor types and products create environmental impact of various kinds and magnitudes.

    This study was initiated by the authors in order to evaluate the Twister™- method’s environmental pros and cons in relation to other traditional floor care methods. This has been ascertained through a Life Cycle Assessment which was conducted within the study. The study has been in co-operation with HTC Sweden AB, the developer of the Twister™- method.

    A Life Cycle Assessment helps to identify and quantify the environmental impact of a product or a service, from a holistic perspective, which incorporates extraction of materials, their manufacture, use and waste management. The software application SimaPRo 7.0 has been used in this study, from which the Eco-indicator 99 method has been selected.

    In the study, the Twister™ method is compared with other floor care methods using polish and wax. The analysis also includes a breakdown of the Twister™ method, as well as a breakdown of the Twister™ pad manufactured by HTC Sweden AB.

    The results show that the elements of the Twister™ method with the greatest environmental impact are the scrubbing machine that is used and the energy consumption that the Twister™ method requires. The results also show that the Twister™ method has a significantly lower environmental impact than floor care methods using polish or wax. The parts of the Twister™ pad that have the greatest environmental impact are the industrial diamonds and the  material that makes up the pad.

    Livscykelanalys av golvvård: En jämförande studie av Twister™-metoden och golvvårdsmetoder med polish och vax2009Rapport (Annet vitenskapelig)
    Abstract [sv]

    I dagens samhälle finns det en stor variation på golv och golvmaterial. Till dessa finns det en stor variation av de produkter och metoder som används för att hålla dessa golv funktionsdugliga. Samtliga golv och produkter ger upphov till miljöpåverkan av olika storlek och sort.

    Denna studie är initierad av författarna för att utvärdera hur Twister™- metoden står sig miljömässigt, jämfört med andra traditionella golvvårdsmetoder. Detta sker genom en livscykelanalys. Arbetet har skett i samarbete med företaget HTC Sweden AB som har utvecklat Twister™-metoden.

    En livscykelanalys ställer en produkt eller tjänst miljöpåverkan utifrån helhetsperspektiv innefattande materialframställning, tillverkning, användning och resthantering. Som hjälp i denna studie har programvaran SimaPro 7.0 använts vari metoden Eco-indikator 99 valts.

    I studien ställs Twister™-metoden mot golvvårdsmetoder innefattande polish och vax. I analysen sker även en nedbrytning av Twister™-metoden likväl en nedbrytning av den Twister™-rondell som HTC Sweden AB tillverkar.

    Resultatet visar att den del av Twister™-metoden som har störst miljöpåverkan är den skurmaskin som används och den energianvändning som Twister™-metoden kräver. Resultatet visar även att Twister™-metoden har signifikant lägre miljöpåverkan än golvvårdsmetoderna polish och vax. De delar av Twister™-rondellen som har störst miljöpåverkan är de industridiamanter och den rondell, som Twister™-rondellen består av.

    Industrial cleaning with Qlean Water: a case study of printed circuit boards2013Inngår i: Journal of Cleaner Production, ISSN 0959-6526, E-ISSN 1879-1786, Vol. 47, s. 19-25Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Many manufacturing companies are looking for ways to substitute environmentally problematic cleaning methods for surface treatments with more environmentally friendly ones. In this paper, one potential solution is described. The Qlean method, based on cleaning with highly pure water (in this paper defined as Qlean Water), is a novel cleaning method. This method, now utilized at one plant at a leading major international electronic company, has substituted previous chemical-based methods for cleaning printed circuit boards prior to lacquering. This paper presents, based on that company's primary data, a comparative study using environmental analysis and economic life cycle cost review between cleaning with Qlean Water and conventional cleaning. The focus is on the environmental and economic performance of the two alternatives. The conclusion is that Qlean Water offers both a significant economic and environmental cost reduction and a better product. This is the case even though all identified economic benefits derived from using Qlean Water, e.g. that the quality and technical lifetime have been extended for the printed circuit boards with the Qlean Water cleaning method, are not considered in the economic analysis.

    Funktionsupphandling av järnvägsinfrastruktur2012Rapport (Annet vitenskapelig)
    Abstract [sv]

    Vid byggnation och underhåll av infrastruktur för järnväg används stora mängder av olika material, vilket medför stor miljöpåverkan från de tidiga produktionsstegen, till exempel råvaruutvinning. Hittills har Trafikverket inte haft något uttalad livscykeltänkande i sitt arbete med upphandlingar. Trafikverket behöver arbeta med miljöledning av nya produkter och välja de mest resurssnåla produkterna i ett livscykelperspektiv. En bättre planerad och förebyggande verksamhet för drift och underhåll skulle möjliggöra förlängd livslängd för järnvägsprodukter.

    Integrerade produkt‐ och tjänsteerbjudanden (till exempel funktions‐ eller resultatorienterade kontrakt) är en affärsmodell som används av allt fler företag. Affärsmodelltypen benämns ofta även som funktionsförsäljning och kan beskrivas som ett livscykelkontrakt med funktionsåtagande. Tidigare forskning har visat att denna typ av affärsmodell, ofta ökar drivkrafterna för förändring och därmed ökad kosteffektivitet och kvalitet ur ett livscykelperspektiv.

    Det övergripande syftet med det här projektet är att;

    ta fram metoder, som stödjer Trafikverket, att utveckla sina sätt att utformaupphandlingsspecifikationer.

    Mer specifikt så har det undersöks om integrerade produkt‐ och tjänsteerbjudande kan förbättra förvaltningen av järnvägsinfrastruktur, och vad skulle i sådant fall en implementering innebära för riskfaktorer samt hur kan kontrakten utvärderas ekonomiskt‐ och miljömässigt?

    Abstract [en]

    The productivity development for rail and road infrastructure has been weak a long time; and explanation can be found in the traditional contracts used, with little room for incentives for innovation. This literature study investigates the use of the few realized PSS contracts within the rail and road infrastructure. The descriptions and the scientific reports are on a synoptic level and a majority of the reports are funded by the involved actors, showing that there is an interest for PSS contracts in the industry and indicating significant potential for further research in the area.

    Scenarios for Resource Efficient Rail Infrastructure: Applying Integrated Product Service Offerings2014Inngår i: PRODUCT SERVICES SYSTEMS AND VALUE CREATION: PROCEEDINGS OF THE 6TH CIRP CONFERENCE ON INDUSTRIAL PRODUCT-SERVICE SYSTEMS, Elsevier, 2014, Vol. 16, s. 13-139Konferansepaper (Fagfellevurdert)
    Abstract [en]

    The rail infrastructure in Sweden, with its long lifetime, large amounts of materials used and traditional procurement, has escalating maintenance costs. What would occur if the infrastructure is instead procured as an Integrated Product Service Offering (IPSO)? This paper discusses scenarios for increased resource efficiency and more value for the money spent by applying an IPSO perspective to rail infrastructure. The best option depends on the conditions at the construction site as well as how much the availability of the tracks is valued.

    Socio-technical scenarios and local practice: Assessing the future use of fossil-free alternatives in a regional energy and transport system2020Inngår i: Transportation Research Interdisciplinary Perspectives, ISSN 2590-1982, Vol. 5Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    This article presents results from a project involving local practitioners in the construction of scenarios for a regional energy and transport system. The purpose is to demonstrate how sustainability transitions research can interact with local practice by means of socio-technical scenarios. Combining quantitative data with qualitative storylines, the article presents four scenarios, which describe different ways of using biogas, biodiesel and electricity in four different applications: city buses, inter-city buses, heavy-duty trucks and industrial processes. The article compares the four scenarios in terms of realization possibilities, energy efficiency and greenhouse gas reduction. Focusing on nearterm realization on a commercial basis, the research findings suggest that collaborative scenario construction can be a useful strategy to manage conflicting agendas and engage key stakeholders in dialogues on transition pathways. The article concludes by presenting policy lessons for practice-oriented transition management. The lessons point to the importance of flexibility in system delineations, the critical timing of near-term scenarios, and the use of scenarios to outline local practitioners' agency.

    Classification of Industrial Symbiosis Synergies: Application in the Biofuels IndustryManuskript (preprint) (Annet vitenskapelig)
    Abstract [en]

    Much of the current literature available in the field of industrial symbiosis aims at providing a review of the symbiotic intensity, institutional and environmental contexts and assessments of the activities involved in a synoptic manner. However, literature regarding classification methods for individual material and energy exchanges is limited. In order to obtain better resolution of the characteristics of exchanges and interactions, i.e. synergies, a classification method is produced and tested in this paper. The classification method maps the interactions between different industries as well as the flows of products and utilities through origindestination classifications. Synergies between a core industry and external industries are examined in this paper, with the core industry represented by the biofuels industry, and without geographical boundaries. The classification method can be employed in other research projects and it is hoped that it will provide the background for further studies into conditions necessary for synergy implementation. Furthermore the classification method will provide subsequent details for research into economic and environmental benefits provided by synergies between industries.

    Biofuel Synergy Development: Classification and Identification of Synergies Using Industrial Symbiosis2009Rapport (Annet vitenskapelig)
    Abstract [en]

    Many critics argue that biofuel production worldwide account for huge losses in energy and materials. Moreover, a large portion of studies around biofuel production are concentrated on stand-alone plants, particularly ethanol production. However, by including by-products and making use of excess energy and material streams, industrial symbiosis methods can be applied to biofuel industries to improve both environmental and economical performance. The following report outlines an approach to apply industrial symbiosis to several biofuel industry actors through synergy development. Synergies were produced during a brainstorming session in order to bring forward innovative and technically feasible ideas toward partnership. From those synergies developed, the report outlines a method to classify synergies and cooperation between biofuel and external industries in order to ease implementation and understanding of possible symbiosis options for industry and academia.

    Classification of Industrial Symbiosis Synergies:: Application in the Biofuels Industry2009Inngår i: Industrial Symbiosis and Eco-Industrial Parks, Aalborg: GIN 2009 , 2009, s. 2394-Konferansepaper (Annet vitenskapelig)
    Abstract [en]

    In the production of biofuels for transportation, i.e. biodiesel, bioethanol and biogas, a vast range of unique resource flows, surpluses and by-products exist in each respective process. The current research project aims to find synergies, demands and surplus material and energy flows which will thereafter be applied to the biofuel industry and external industries in a collaborative effort to increase energy efficiencies and environmental performance through the use of synergies and industrial symbiosis. This is being conducted in order to determine conditions for implementation, why some processes and synergies exist, how the processes can be made better and to identify new material flows between industries.

    During an investigation of synergies apparent in the regional biofuel industries, many synergies were discussed during a brainstorming session with industrial actors and researchers. These synergies were recorded and classified in terms of their interaction with other biofuel and external industries. Using the theories of industrial symbiosis, a classification method was developed based upon these interactions as well as the origin and destination of their resources. Previous terms from the theories of synergies research were used as background material. Thereafter symbols and classifications were based on the interactions of the synergy, i.e. between biofuel industries and external synergies. Furthermore the origins/destinations were also classified as either a product/process or as a utility but with expanded and refined boundaries.

    Example: 2UP (A synergy of Class 2, i.e. biofuel to external industry synergy, which originates as a utility and is destined as a product/process for the external industry.)

    Thus far the project has produced a classification scheme for biofuel synergy projects and research. Using the classification method, synergies produced at future brainstorming sessions and discussions with industry will alleviate the reproduction, recording and organization of synergies for upcoming interaction with biofuel industries worldwide.

    Who gets the benefits? An approach for assessing the environmental performance of industrial symbiosis2015Inngår i: Journal of Cleaner Production, ISSN 0959-6526, E-ISSN 1879-1786, Vol. 98, s. 263-271Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Industrial symbiosis networks are generally assumed to provide economic and environmental benefits for all firms involved, though few quantifications have been produced in the literature, and the methods for these quantifications have varied. This paper provides an approach to quantify the environmental performance of industrial symbiosis networks using guidance from the literature of life cycle assessment. Additionally, an approach to distribute credits due to exchanges for firms in the industrial symbiosis network is outlined. From the approach, influential methodological considerations used for the quantifications are discussed, including e.g. the production of reference systems, allocation methods, system boundaries and functional unit. The implications of such an approach may be beneficial for the industrial symbiosis community and provide information crucial for taxes, subsidies, business relations, expansion possibilities for the network, marketing and other issues related to the environmental performance of firms in the industrial symbiosis network.

    Assessing the Environmental Performance of Integrated Ethanol and Biogas Production:: Quantifying Industrial Symbiosis in the Biofuel Industry2011Rapport (Annet vitenskapelig)
    Abstract [en]

    As the production of biofuels continues to expand worldwide, criticism about many issues, including the energy output versus input and the competition with food, has been raised andthe sustainability of biofuels in recent years has been constantly debated. However, the current biofuel systems may be optimized to increase the energy efficiency and environmentalperformance. By using concepts from industrial symbiosis, the material and energy exchangesmay be optimized to result in these performance improvements. This paper offers aquantification of the environmental performance of industrial symbiosis in the biofuelindustry through integration of biogas and ethanol processes using a life cycle approach.Results show that although increasing integration between the biogas and ethanol plants isassumed to produce environmental benefits, not all impact categories have achieved this andthe results depend upon the allocation methods chosen. Thus the increasing integration alsobrings about increased complexity for the system.

    As the production of biofuels continues to expand worldwide, criticism about, e.g. the energy output versus input and the competition with food has been questioned. However, biofuels have the possibility to be optimized in order to improve the environmental performance. This could be accomplished through the use of concepts from industrial symbiosis. This paper provides a quantification of the environmental performance of industrial symbiosis in the biofuel industry through integration of biogas and ethanol processes using a life cycle approach. Results show that although increasing integration is assumed to produce environmental benefits, not all impact categories have achieved this and the results depend upon the allocation methods, energy system and assumptions chosen.

    It is generally assumed that industrial symbiosis creates economic and environmental benefits for all firmsinvolved, though only a few quantifications have been produced in the literature. An approach to quantifyenvironmental performance of industrial symbiosis using life cycle assessment has been provided,outlining the choice of functional unit, system boundaries, impact assessment and allocation as well as thedistribution of benefits among firms in the symbiotic activity. The implications of such an approach maybe beneficial for the industrial symbiosis and life cycle assessment communities and provide informationcrucial for taxes, subsidies, business relations, marketing and other issues related to the environmentalperformance of firms in the industrial symbiosis network.

    Integrated early-stage environmental and economic assessment of emerging technologies and its applicability to the case of plasma gasification2023Inngår i: Journal of Cleaner Production, ISSN 0959-6526, E-ISSN 1879-1786, Vol. 382, artikkel-id 134684Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Economic and environmental impact assessments are increasingly being adopted in the design and implementation of emerging systems. However, their emerging nature leads to several assessment challenges that need to be addressed to ensure the validity and usefulness of results in understanding their potential performance and supporting their development. There is the need to (i) account for spatial and temporal variability to allow a broader perspective at an early stage of development; (ii) handle uncertainties to systematically identify the critical factors and their interrelations that drive the results; (iii) integrate environmental and economic results to support sound decision-making based on two sustainability aspects. To address these assessment challenges, this study presents an alternative approach with the following corresponding features: (i) multiple scenario development to conduct an exploratory assessment of the systems under varying conditions and settings, (ii) global sensitivity analysis to identify the main critical factors and their interrelations, and (iii) trade-off and eco-efficiency analysis to integrate the economic and environmental results. The integrated approach is applied to a case study on plasma gasification for solid waste management. The results of the study highlight how the approach allows the identification of the dynamic relations between project settings and surrounding conditions. For example, the choice of gasifying agent largely depends on the background energy system, which dictates the impacts of the process energy requirement and the savings from the substituted energy of the syngas output. Based on these findings, the usefulness and validity of the proposed integrated approach are discussed in terms of how the key assessment challenges are addressed and how it can provide guidance for the development of emerging systems.

    Innovation Potentials of Using Solvent-free Industrial Cleaning in Swedish Manufacturing Industry2008Inngår i: Proceedings of Sustainable Innovation 08 - Future products, technologies and industries: 13th International Conference part of the ‘Towards Sustainable Product Design’ series of conferences, 27-28 October 2008, Malmö, Sweden, 2008Konferansepaper (Fagfellevurdert)
    Abstract [en]

    In this research collaboration project between SMEs and academia a new way of cleaning machine parts have been developed. The cleaning company Servicestaden and researchers at Linköping University have discovered new ways of cleaning without the use of solvents. In the research project called ‘Solvent-Free Industrial Cleaning’ (SOFIQ) it has been found that cleaning with the SOFIQ-technology is more environmentally sound than with traditional cleaning techniques. However, there is a major challenge to keep up the pace of cleaning within manufacturing since it often have high demands of short lead times. This is a challenge that will be constraining the use of the method.

    Solvent-free Industrial Cleaning of Printed Circuit Boards2009Inngår i: Proceedings of EcoDesign 2009, Sapporo, Japan, 2009, s. 823-828Konferansepaper (Fagfellevurdert)
    Abstract [en]

    The manufacturing industry today uses different kinds of chemicals in its cleaning processes. The industrial cleaners often contain some sort of degreasing chemical to clean parts and components before for instance sur-face treatment processes. These types of cleaning meth-ods imply expensive and dangerous handling of chemi-cals in the manufacturing process, as well as in the transportation of hazardous waste. Furthermore, the cleaning processes also use a substantial amount of en-ergy for cleaning.The aim of this paper is to explore the potential of how ultra-clean water cleaning can be used in the manufac-turing industry. In order to meet the aim, a case study was conducted at a electronic manufacturer. The data for this research was collected mainly through interviews, but also by industrial study visits.The results from this research show that using solvent-free industrial cleaning with ultra-clean water is benefi-cial from the perspectives of quality, environment and business. The quality improvement is the most important benefit that the electronic manufacturer can see by using solvent-free industrial cleaning for their printed circuit boards.
