    Challenges when including sustainability aspects in product development at two large manufacturing companies in Sweden2019Ingår i: Technologies and Eco-innovation towards Sustainability I: Eco Design of Products and Services / [ed] Allen H. Hu, Mitsutaka Matsumoto, Tsai Chi Kuo, Shana Smith, Singapore: Springer, 2019, Vol. I, s. 229-243Konferensbidrag (Refereegranskat)
    Abstract [en]

    When including sustainability aspects in product development challenges may arise. The aim of this paperis to expand current knowledge about challenges faced by manufacturing companies when includingsustainability aspects in product development. To fulfil the aim, a multiple case study at two largemanufacturing companies was conducted. Data was collected through semi-structured interviews,complemented with data from the companies’ sustainability reports. The novelty of this research is an expansion of the existing knowledge about these types ofchallenges. Additionally, drivers for the companies’ inclusion of sustainability aspects in productdevelopment and meaning of sustainability for the companies, are described. The results show that thechallenges differ to a large extent between the two companies. Despite the differences, challenges causedby a lack of recourses, lack of knowledge and need to fulfil economic goals are the most commonly described challenges at the companies.

    Feedback from Remanufacturing: Its Unexploited Potential to Improve Future Product Design2019Ingår i: Sustainability, ISSN 2071-1050, E-ISSN 2071-1050, Vol. 11, nr 15, s. 1artikel-id 4037Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Company interest and research in the circular economy and remanufacturing have increased as a means of reducing negative environmental impacts. Remanufacturing is an industrial process whereby used products are returned to a state of like-new. However, few products are designed for remanufacturing, and further research and industrial efforts are needed to facilitate more widespread use of design for remanufacturing. One crucial factor facilitating design for remanufacturing is the integration of feedback in the product design process. Thus, the objective of this paper is to analyse feedback flows from remanufacturing to product design. Hence, a literature study and multiple case studies were conducted at three companies that design, manufacture and remanufacture different kinds of products. The cross-case analysis revealed the five barriers of the lack of internal awareness, lack of knowledge, lack of incentives, lack of feedback channels and non-supportive organisational structures, and the five enablers of business opportunities, integrated design processes, customers’ demand, laws, regulations and standards, and new technologies. To establish improved feedback from remanufacturing to product design, the barriers need to be addressed and the enablers explored. Thus, improved feedback from remanufacturing to product design will improve the design of future products suited for a more circular economy.

    How to Improve Remanufacturing?-A Systematic Analysis of Practices and Theories2019Ingår i: Journal of manufacturing science and engineering, ISSN 1087-1357, E-ISSN 1528-8935, Vol. 141, nr 2, artikel-id 021004Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Remanufacturing has gained attention from industry, but the literature lacks the scientific comprehension to realize efficient remanufacturing. This hinders a company from commencing or improving remanufacturing efficiently. To fill this gap, the paper proposes a set of practical success factors for remanufacturing. To do so, it analyzes remanufacturing practices in industry through interviews with staff from remanufacturing companies with long experience. The practical success factors are found to be (1) addressing product and component value, (2) having a customer-oriented operation, (3) having an efficient core acquisition, (4) obtaining the correct information, and (5) having the right staff competence. Next, the paper further analyzes remanufacturing processes theoretically with both cause and effect analysis and means-ends analysis. Since the factors show that, among other things, the product/service system (PSS) is highly relevant to remanufacturing in multiple ways, theories on the PSS are partly utilized. As a result, the distinctive nature of remanufacturing underlying in the processes is found to have high variability, high uncertainty and, thus, also complexity. The obtained insights from practice and theory are found to support each other. In addition, a lishbone diagram for remanufacturing is proposed based on the analysis, including seven ms, adding two new ms (marketing and maintenance) on top of the traditional five ms (measurement, material, human, method, and machine) in order to improve customer value. The major contribution of the paper lies in its insights, which are grounded in both theory and practice.

    Supporting design for remanufacturing: A framework for implementing information feedback from remanufacturing to product design2019Ingår i: Journal of Remanufacturing, ISSN 2210-464X, s. 1-20Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Remanufacturing is an industrial process turning used products into a condition of like new or better. Remanufacturing is also one strategy that salvages the value put into products during manufacturing and thus reduces the environmental impact of products over the life-cycle. However, not many products are designed for remanufacturing, and there is rarely any feedback from remanufacturing to design. Since design for remanufacturing is not applied at most manufacturing companies, there is a need to support companies, for example, by information feedback methods. By implementing feedback transfer from remanufacturing to design and employing design for remanufacturing, the remanufacturing process is more likely to be effective and efficient. The aim of this paper is to present a framework that supports design for remanufacturing by the implementation of structured feedback from remanufacturing to design. The framework aims at strategically outlining and practically implementing information feedback from remanufacturing to design. A case company where the framework has been initialised is also presented.

    11 Rules of Design for Manufacturing CFRP Components2018Ingår i: So You Want to Design Aircraft: Manufacturing with Composites / [ed] Jean Broge, SAE International , 2018, First, s. 29-42Kapitel i bok, del av antologi (Refereegranskat)
    Abstract [en]

    Carbon-fiber-reinforced plastic (CFRP) is one of the most commonly used materials in the aerospace industry today. CFRP in pre-impregnated form is an anisotropic material whose properties can be controlled to a high level by the designer. Sometimes, these properties make the material hard to predict with regards to how the geometry affects manufacturing aspects. This chapter describes 11 design rules that describe geometrical design choices and deals with manufacturability problems that are connected to them, why they are connected, and how they can be minimized or avoided. Examples of design choices dealt with in the rules include double curvature shapes, assembly of uncured CFRP components, and access for nondestructive testing.

    Circular Economy and design for remanufacturing2018Ingår i: Designing for the Circular Economy / [ed] Martin Charter, Oxon: Routledge, 2018, First, s. 186-199Kapitel i bok, del av antologi (Refereegranskat)
    Abstract [en]

    Circular Economy (CE) means that resources should be kept in use when a product reaches its End-of-Use so they can be reused several times to create further value for the product’s next users. An important starting point with CE is the design of products and manufacturing processes. Products can be designed to be used longer, repaired, upgraded, remanufactured or eventually recycled, instead of being thrown away. With product remanufacturing, the geometrical form of the product is retained and its associated economic value is preserved. Having products designed for several use periods including remanufacturing extends the use-time of products.

    Inclusion of sustainability aspects in product development – two industrial cases from Sweden2018Ingår i: Proceedings of NordDesign - Design in the era of digitalization, 2018Konferensbidrag (Refereegranskat)
    Abstract [en]

    Knowledge on how to include sustainability aspects in product development has increased during the last 25 years. Research has contributed with literature reviews, case studies, and the development of supporting methods, frameworks and guidelines.

    Despite the large amount of knowledge generated on how to include sustainability aspects in product development, there are few studies that focus on describing how manufacturing companies, in real life, include sustainability aspects in their product development.

    The aim of this paper is to describe how two manufacturing companies include sustainability aspects in their product development, make a comparison between them, and relate findings with prior studies. To fulfil the aim, a multiple case study at two large Swedish manufacturing companies was conducted. Data was collected through semi-structured interviews and by analyzing sustainability reports.This paper provides two novel context-dependent descriptions of how large manufacturing companies include sustainability aspects in their product development. There are several similarities identified between the two companies in this study and descriptions inprior studies of how manufacturing companies include sustainability aspects in their product development. For example, there are manufacturing companies that systematically include sustainability aspects in product development; however, what is systemized differs between thecompanies.This research suggests that the easier an aspect can be related to the design of the product the more likely the aspect will be considered by actors in the product development function, such as design engineers. Additionally, this research indicates that the product owner is animportant internal actor who affects the inclusion of sustainability aspects in product development, and especially the inclusion of sustainability aspects in product requirements. Further studies are suggested on how product owners elicit and prioritize sustainability aspects, how these aspects are formulated in product requirements, as well as how, and how commonly, marketing and sales elicit sustainability aspects from customers.

    Integrated product service offerings: Challenges in setting requirements2018Ingår i: Journal of Cleaner Production, ISSN 0959-6526, E-ISSN 1879-1786, Vol. 201, s. 879-887Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The objective of this paper is to explore what challenges exist when setting requirements for an Integrated Product Service Offering (IPSO). An IPSO, sometimes called Product Service System, is a concept with increased interest from manufacturing companies. It consists of a combination of products and services that, based on a life cycle perspective, have been integrated to fit targeted customer needs. In order to achieve a successful IPSO, it is important to collect aspects from many actors, something which sometimes is challenging for companies moving towards providing IPSOs.

    The four challenges found when setting requirements in IPSO development are; identification and inclusion of relevant aspects from relevant actors throughout the IPSO’s life cycle, understanding of the underlying aspects for all requirements for all elements of the offering, prioritization of requirements, and the difficulty to track how requirements affect each other between different elements in the IPSO.

    The methodology used to find these challenges was a combination of a structured literature review and an interview study at three manufacturing companies moving towards providing IPSOs.

    Remanufacturing challenges and possible lean improvements2018Ingår i: Journal of Cleaner Production, ISSN 0959-6526, E-ISSN 1879-1786, Vol. 172, s. 3225-3236Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Remanufacturing is a viable way to prolong the useful life of an end-of-use product or its parts. Despite its economic, environmental, and social benefits, remanufacturing is associated with many challenges related to core (used product or its part) availability, timing and quality. The aim of this paper is to study how lean production could be used to tackle remanufacturing process challenges and contribute to shorter lead times. To meet this aim, we conducted a literature review and case studies of four remanufacturing companies. The case companies remanufacturing challenges were: (1) a lack of material requirements planning system, (2) poor core information, (3) a lack of core material, (4) poor spare parts information, (5) a lack of spare parts material, (6) insufficient quality management practices, (7) large inventories, (8) stochastic remanufacturing processes, (9) a lack of supply-demand balance, and (10) insufficient automation. These challenges contribute to long and variable remanufacturing process lead times. To tackle remanufacturing challenges, seven lean-based improvements with a major effect on improvements in lead time were suggested: standard operations, continuous flow, Kanban, teamwork, employee cross-training, layout for continuous flow, and supplier partnership. Providing that the suggested improvements are implemented, a possible lead time reduction of 83-99 per cent was projected.

    Reverse Logistic Transportation and Packaging Concepts in Automotive Remanufacturing2018Ingår i: Procedia Manufacturing, E-ISSN 2351-9789, Vol. 25, s. 154-160Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    A key process in a closed-loop supply chain is managing and challenging the transportation and packaging management. Strict environmental regulations in connection with transport of environmentally hazardous substances (e.g. oil) are offering a highcost-saving potential in connection with an optimised transportation and packaging concept. The aim of this case orientated paperis to provide the framework for the management of reverse flow of materials in automotive industry. The emphasis is placed onthe remanufacturing activities. To obtain and verify the necessary information for the above mentioned problems, differentmethods and techniques have been applied: 1) Relevant, available literature in connection with this matter was studied; 2) Dataand documents was requested directly by relevant market actors; 3) The clustered data was analysed and samples werehighlighted; and 4) The data was evaluated and recommended courses of action were given. The results show that the mainproblems appear in the area of forward and reverse logistics: Packaging concepts which do not protect the product in an optimalway (forward / reverse logistics). Moreover, packaging concepts which do not protect the environment against potential negativeinfluence of a used part (reverse logistics) A best practice for the transportation of engine components is given and evaluated: Anengine in a metal frame with oil-pan. Securely attached by bolts. Packed in plastic bag.

    Key success factors for implementing Upgrading Remanufacturing2017Ingår i: Proceedings of International Conference on Remanufacturing (ICoR-17), 2017, s. 33-46Konferensbidrag (Refereegranskat)
    Abstract [en]

    Increasing volume of waste in Europe, reduced availability of critical primary resources and new emerging trends towards “green” products push European manufacturers towards the implementation of ‘circular economy’. Product upgrading, i.e. the process of providing new functionalities to products through collection, disassembly/substitution and remanufacturing, could represent an effective solution to support the transition to circular economy. However, economic and environmental sustainability, legislation boundaries, industrial benefits and social impact of design for upgradability and upgrading remanufacturing are still debated in many sectors, and companies still perceive high risks in this transition.

     

    The aim of the paper is to clarify the key success factors for companies that have the willingness to include upgrading remanufacturing in their businesses. An emphasis is placed on how the application of new service-oriented business models for product upgrade and design for remanufacturing can support this implementation and bring high value-added to circular economy businesses.

     

    The methodology used to reach the aim of the paper was to map existing business approaches through a literature review focused on the existing upgrading strategies. Next, a study of real existing case studies of product upgrading was developed. Within this step, the identification of common success factors and a favourable scenario for the implementation of upgrading remanufacturing was conducted.

    Lean improvements in remanufacturing: solving information flow challenges2017Ingår i: QMOD proceedings, 2017Konferensbidrag (Refereegranskat)
    Abstract [en]

    Purpose - One efficient way to prolong the functional life of used products is remanufacturing. Compared to manufacturing, remanufacturing is a complex industrial process due to among other things high product variability, low production volumes and uncertain quality of returned used products. Remanufacturers are dependent on product information from Original Equipment Manufacturers (OEM), but that information is often not shared. Remanufacturers struggle to access or develop lacking product information and need a strategy to address information flow challenges. Lean could be a suitable strategy to improve the information flow. Therefore, the purpose of the paper is to identify and suggest Lean improvements to address remanufacturer’s information flow challenges.

    Methodology/Approach - Based on a case study of a filling machine remanufacturer, this paper discusses the information flow challenges and Lean-based solutions. The data was collected through a three-hour focus group interview combined with a Value Stream Mapping (VSM) method with the participation of seven company employees representing sales, logistics, quality, maintenance and production departments.

    Findings - Two key information flow challenges were identified at the company: a lack of available product data and miscommunication with the OEM, and poor internal information sharing. The analysis of the identified challenges and improvement ideas created a platform for developing Lean-based solutions:1) developing standard operations through instruction checklists and kitting areas;2) boosting supplier and customer relations through six best partnering practices; and3) developing people and teams through teamwork and training.

    Originality/Value of paper – All industries have their own specific challenges and development needs. This paper focuses on information flow challenges in remanufacturing. Original product information is often not shared, even when the remanufacturer has a contract with the OEM. Only few remanufacturers work with Lean today, but Lean could be a strategy to address the information flow challenges. This paper contributes to the knowledge on how Lean could be applied in the remanufacturing context.

    Remanufacturing lead time reduction through a Just-in-time Lean strategy: a case study on Laptops2017Ingår i: Proceedings of 3rd International Conference onRemanufacturing (ICOR17), 2017, s. 47-56Konferensbidrag (Refereegranskat)
    Abstract [en]

    The annual accumulation of electronic equipment waste, including IT, in the European Union reached at least nine million tons in 2015. These products usually have a limited lifespan, and many consumers tend to buy new devices before their old ones stop working.

    Remanufacturing is one of the effective ways to contribute to IT waste reduction. Product life extension through remanufacturing gives the product one or several more users throughout its life cycle. When remanufacturing is applied to laptops, the extraction of virgin materials, the energy consumption for manufacturing and the amount of waste are all reduced. However, today many remanufacturers of IT face challenges associated with inefficient and complex processes due to uncertainties in core timing, volume and quality. Lean remanufacturing is typically treated as an operations improvement strategy that deals with the process challenges. Just-in-time is one of the lean strategies to address inefficient, long and stochastic operations. Therefore, the aim of this paper is to investigate how just-in-time can help to reduce remanufacturing process lead time, and consequently increase process efficiency.

    The data was collected through a focus group interview and a simplified Value Stream Mapping lean method at an IT remanufacturing company. The company’s remanufacturing process is assessed regarding process lead time and efficiency. Based on the case company's process challenges, the following possible just-in-time solutions were developed for remanufacturers: cellular layout, distinct product family flows and Kanban reordering system.

    11 Rules of Design for Manufacturing when Producing Pre-Impregnated Carbon Fiber-Reinforced Plastic Components: an Application at SAAB Aerostructures2016Ingår i: SAE Technical Papers, Society of Automotive Engineers, 2016, s. 1-8, artikel-id 2016-01-2124Konferensbidrag (Refereegranskat)
    Abstract [en]

    Carbon ber-reinforced plastic (CFRP) is one of the most commonly used materials in the aerospace industry today. CFRP in pre- impregnated form is an anisotropic material whose properties can be controlled to a high level by the designer. Sometimes, these properties make the material hard to predict with regards to how the geometry affects manufacturing aspects. This paper describes eleven design rules originating from different guidelines that describe geometrical design choices and deals with manufacturability problems that are connected to them, why they are connected and how they can be minimized or avoided. Examples of design choices dealt with in the rules include double curvature shapes, assembly of uncured CFRP components and access for non-destructive testing (NDT). To verify the technical content and ensure practicability, the rules were developed by, inter alia, studying literature and performing case studies at SAAB Aerostructures. The research was done through a collaboration between Linköping University and SAAB Aerostructures in a state-funded project. This ensured a balanced approach between academic advancement and usefulness in commercial projects.

    A stepwise method towards products adapted for remanufacturing2016Ingår i: DS 84: Proceedings of the DESIGN 2016 14th International Design Conference / [ed] Marjanovic Dorian, Storga Mario, Pavkovic Neven, Bojcetic Nenad, Skec Stanko, The Design Society, 2016, s. 321-330Konferensbidrag (Refereegranskat)
    Abstract [en]

    Remanufacturing is an important component of a resource-efficient manufacturing industry [see e.g. Rose and Ishii 1999; Steinhilper 1998; Sundin and Lee 2011]. By keeping components and their embodied material in use for a longer period of time, significant energy use and emissions to air and water (e.g. CO2 and SO2) can be avoided. According to Sundin and Lee [2011], environmental comparisons of remanufacturing versus new manufacturing and/or material recycling show environmental benefits for remanufacturing. This is due to alleviation of depletion of resources, reduction of global warming potential, and better chances to close the loop for safer handling of toxic materials [Sundin and Lee 2011]. In addition to its environmental benefits, remanufacturing provides opportunities for the creation of highly skilled jobs and economic growth.

     

    In order to make remanufacturing businesses more beneficial, product information should be accessible for the remanufacturing personnel and the products should be adapted for the remanufacturing process [Sundin and Bras 2005]. Although previous research identified information that could be fed back to the design phase from remanufacturing [e.g. Lindkvist and Sundin 2012] (see Table 1), such information is not often available in the design phase [Lindkvist and Sundin 2015]. Design for remanufacturing (DfRem) aims at facilitating the remanufacturing process so that e.g. disassembly, cleaning, reprocessing and reassembly are facilitated [Sundin and Bras 2005]. However, products are often not designed for remanufacture [Sundin and Bras 2005; Hatcher et al. 2011], although there do exist guidelines for design for remanufacturing [see e.g. Charter and Gray 2008, Sundin and Bras 2005].

     

    Successful integration of DfRem requires support on a strategic as well a tactical level, i.e. both what to do and how to do it [Yang et al. 2014]. Further, Hatcher et al. [2014] point out a gap in research regarding the operational factors influencing DfRem integration into the design process. In their findings, external factors such as customer demand and internal factors such as the OEM-remanufacturer relationship were identified. This paper addresses the combination of the strategic and tactical approaches, targeting the internal factors affecting DfRem integration into the design process. The proposed method is directed at companies that include both design and remanufacturing in their operations, and specifically supports integration of information from remanufacturing into the design process in order to better adapt products for remanufacturing.

    A STEPWISE METHOD TOWARDS PRODUCTS ADAPTED FOR REMANUFACTURING2016Ingår i: DS 84: PROCEEDINGS OF THE DESIGN 2016 14TH INTERNATIONAL DESIGN CONFERENCE, VOLS 1-4 / [ed] Marjanovic Dorian, Storga Mario, Pavkovic Neven, Bojcetic Nenad, Skec Stanko, DESIGN SOC , 2016, Vol. 1-4, s. 321-330Konferensbidrag (Refereegranskat)
    Abstract [en]

    Currently, products are often not designed for remanufacturing. Further, there is a lack of feedback from remanufacturing to product design. Thus, information from remanufacturing and design for remanufacturing needs to be integrated in a better way into the product development processes.

    In this paper a stepwise method towards products adapted for remanufacturing is described. The method is directed at OEMs that remanufacture, and specifically supports integration of information from remanufacturing into the design process in order to better adapt products for remanufacturing.

    Analysing the service information transfer in the service development process at two automotive companies2016Ingår i: 23RD CIRP CONFERENCE ON LIFE CYCLE ENGINEERING, ELSEVIER SCIENCE BV , 2016, Vol. 48, s. 51-56Konferensbidrag (Refereegranskat)
    Abstract [en]

    As service renders an increasing share of companies revenues and affects a products environmental performance, the effectiveness of the services carried out is important. The aim of this paper is to analyse the service information transfer in the service development process at two automotive companies in order to explore its inefficiencies, and to promote steps to make it more efficient in the future. The work process during service development was mapped, focusing on the information transfer, including databases utilized and types of instructions produced. The studies show that some information provided to the service designers is insufficiently detailed and some databases are incompatible, causing rework in the service development process. Further, the information provided to service technicians comes in multiple formats, causing inefficiency in the service process, and feedback to the service designers is too time consuming.

    Development of a Design for Manufacturing and Assembly (DFM/A) methodology concerning products and components made in composites of Carbon Fiber Reinforced Plastics (CFRP) used in the Aerospace Industry2016Ingår i: Swedish Production Symposium  (SPS-16), 2016Konferensbidrag (Refereegranskat)
    Abstract [en]

    Composites of carbon fiber reinforced plastics (CFRP) are being used to a greater extent in the aerospace industry due to their desired material properties. CFRP are attractive to use since they are light, strong and make it possible to integrate parts in in ways not possible in other materials. However, using CFRP is challenging since they may lead to more problems in final assembly. The aim of this paper is to describe the development of a Design for Manufacturing and Assembly (DFM/A) methodology for manufacturing aircraft structures in CFRP. The research methodology consisted of interviews, observations, workshops and tests at SAAB Aerostructures, but also interviews with other companies regarding their design for manufacturing methods. The result is a methodology that includes an approach that describes when and how the DFM/A work should be conducted and organized, and how it is linked and integrated into the company’s product development process. The DFM/A methodology developed makes it possible to include manufacturing aspects into the existing product development process to ensure that manufacturing is considered in the design phase, with special focus on CFRP.

    Investigating types of information from WEEE take-back systems in order to promote Design for Recovery2016Ingår i: Sustainability through innovation in product life cycle design / [ed] Matsumoto, M., Masui, K., Fukushige, S., Kondoh, S, Springer, 2016Konferensbidrag (Refereegranskat)
    Abstract [en]

    WEEE (Waste Electrical and Electronic Equipment) recovery facilities have been set up for the last decade to promote a circular economy. Their activities focus on the reuse, remanufacturing and/or recycling of products. Currently, little information reaches designers regarding the requirements that these facilities have on product design. Therefore, most products are not designed to be properly recovered. The aim of this paper is to explore the nature of product life-cycle information from recovery organisations that could be shared in order to improve resource efficiency. The focus is on how information exchange can benefit the end-of-life phase of forthcoming designed products. Two levels of information have been identified, macroscopic and microscopic. Our study is illustrated with a detailed analysis of the French WEEE compliance scheme and an in-depth analysis of an IT remanufacturing facility in Sweden.  Based on the cases studies we have identified current and potential information flows between different stakeholders that could benefit design for recovery.

    Perspectives on recycling centres and future developments2016Ingår i: Applied Ergonomics, ISSN 0003-6870, E-ISSN 1872-9126, Vol. 57, s. 17-27Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The overall aim of this paper is to draw combined, all-embracing conclusions based on a long-term multidisciplinary research programme on recycling centres in Sweden, focussing on working conditions, environment and system performance. A second aim is to give recommendations for their development of new and existing recycling centres and to discuss implications for the future design and organisation. Several opportunities for improvement of recycling centres were identified, such as design, layout, ease with which users could sort their waste, the work environment, conflicting needs and goals within the industry, and industrialisation. Combining all results from the research, which consisted of different disciplinary aspects, made it possible to analyse and elucidate their interrelations. Waste sorting quality was recognized as the most prominent improvement field in the recycling centre system. The research identified the importance of involving stakeholders with different perspectives when planning a recycling centre in order to get functionality and high performance. Practical proposals of how to plan and build recycling centres are given in a detailed checklist. (C) 2016 Elsevier Ltd. All rights reserved.

    The role of Product-Service Systems regarding information feedback transfer in the product life-cycle including remanufacturing2016Ingår i: PRODUCT-SERVICE SYSTEMS ACROSS LIFE CYCLE, ELSEVIER SCIENCE BV , 2016, Vol. 47, s. 311-316Konferensbidrag (Refereegranskat)
    Abstract [en]

    With a Product-Service System (PSS), the producer often has control of its products during multiple life-cycles, and thus there are more incentives for design for service and remanufacturing in comparison to traditional sales. The aim of this paper is to explore the role of PSS regarding information feedback transfer in the product life-cycle including remanufacturing. The paper explores two industrial cases where PSS does not yet act as a facilitator for transferring information feedback from remanufacturing to product designers. However, the full potential of PSS is not yet utilized at the companies, and their products are neither designed for PSS nor remanufacturing. (C) 2016 The Authors. Published by Elsevier B.V.

    Assessing barriers for available life-cycle information feedback transfer to product design2015Ingår i: ICoR- 2nd International Conference on Remanufacturing, 2015Konferensbidrag (Refereegranskat)
    Abstract [en]

    The design of products greatly influences the performance of the product in the rest of the product’s life-cycle phases, e.g. manufacturing, use/maintenance and end-of-life processes. In order to design more sustainable products, information from all life-cycle phases should be implemented in structured ways via e.g. eco-design tools in the design process. Remanufacturing is one viable end-of-life strategy that is environmentally beneficial as it will preserve most of the material and energy put into the initial product and/or its components. Although the product design determines a large portion of the remanufacturability of a product, few companies apply design for remanufacturing on their products.The aim of this paper is to show what type of feedback is available at remanufacturers, and to explore the barriers that prevent that feedback from reaching product development. Using the case study methodology, data have been collected through semi-structured interviews with four remanufacturing companies focusing on the information exchange between the departments of remanufacturing and product development.The case study results show that there is feedback from the remanufacturers concerning a wide variety of design aspects. Furthermore, the remanufacturers have feedback about information they lack from design and the use phase including service. At present, however, there is no feedback provided from remanufacturing to design in the cases studied. Thus, the barriers for providing available life-cycle information feedback are assessed. There are both internal and external barriers. Between design and remanufacturing the barriers include e.g. lack of knowledge and organisational aspects. Further influencing the lack of feedback are managerial aspects such as the business case and specifications lacking remanufacturing aspects and thus not supporting design for remanufacturing. However, design changes such as different joining methods, a higher degree of standardization and different material selections could be very beneficial for remanufacturing and thus the environment.

    Challenges and trends within eco-design2015Ingår i: EcoDesign 2015 International Symposium, 2015Konferensbidrag (Övrigt vetenskapligt)
    Abstract [en]

    Despite years of research and other activities in society the anthropogenic impact on nature still increase. Eco-design has a potential to reduce this impact, but yet a minority of companies practice it. The aim of this paper is to identify current challenges and trends within eco-design. In addition, the paper further aims to disclose important eco-design related research gaps. Eco-design challenges and trends have been studied in 22 selected papers, out of 52, found in ScienceDirect during April 2015. In addition, four snowballed papers from the same database and one standard were included. Challenges and trends are revealed and structured into four categories; 1) system and success level; 2) strategy level; 3) action level; and 4) tools level. Most challenges and least trends are found within the first category: systems and success level. An implication from the result is that research and other activities should more than today be supported by a system and success level. Future research should focus on understanding the industry’s perspective, help set requirements in product specifications, create low economic risk implementation roadmaps, understanding how to map knowledge and information to aid eco-design implementation. It is also preferable to facilitate an efficient inclusion of social and economic aspects when practicing eco-design.

    Core (product) Acquisition Management for remanufacturing: a review2015Ingår i: Journal of Remanufacturing, ISSN 2210-4690, nr 4Artikel, forskningsöversikt (Refereegranskat)
    Abstract [en]

    Core acquisition is essential for the success of remanufacturing business. To describe the current status of the quantitative research in Core Acquisition Management and to indicate possible future research directions, a literature review is conducted in this paper about the quantitative modeling in Core Acquisition Management research area. The activities included in Core Acquisition Management are categorized into topics such as acquisition control, forecasting return, return strategies, quality classification and reverse channel design. While most of the studies focus on acquisition control, studies on return strategies and return forecast are relatively limited. Furthermore, this paper analyzes the research papers according to the key assumptions such as, hybrid/non-hybrid remanufacturing systems, acquisition functions, quality classification methods and perfect/imperfect substitutions. In conclusion, studies based on the assumptions of non-hybrid remanufacturing systems and imperfect substitution should gain more attentions, since these situations frequently occur in practice but are less investigated in the existing literature. In addition, empirical validation of the various forms of the acquisition function (relations between acquisition incentives and acquisition volume) should be important for further investigations.

    Essence of remanufacturing derived from analysis of practices and theories2015Konferensbidrag (Övrigt vetenskapligt)
    Abstract [en]

    Remanufacturing has gained attention from the manufacturing industry, but still lacks scientific insights in the literature for remanufacturers’ success. The paper proposes a set of key factors that are important for successful remanufacturing. To do so, it first analyses remanufacturing practices in industry through the authors’ own interviews with practitioners, and derives key factors for successful remanufacturing. They are: 1) product and component value; 2) customer-oriented operation; 3) collection of cores; 4) correct information; and 5) personnel competence. The first two factors show Product/Service System theory is highly relevant to remanufacturing. Then, having those factors in mind, it analyses remanufacturing processes theoretically. The distinctive nature of remanufacturing underlying in the processes is found to have high variability, high uncertainty and, thus, high complexity. The obtained insights are eventually represented with a Fishbone diagram. The value of the paper lies in its insights, grounded in both practice and scientific theory.

    Motives and barriers of the remanufacturing industry in China2015Ingår i: Journal of Cleaner Production, ISSN 0959-6526, E-ISSN 1879-1786, ISSN 0959-6526, Vol. 94, s. 340-351Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Realizing the importance of remanufacturing for sustainable development due to the large scale of the economy and its increasing pressure on the environment, the Chinese government has been strongly promoting its remanufacturing industry since 2008. The objective of this paper is to identify the motives and barriers for remanufacturing in China. According to the survey conducted among remanufacturers in China, environmental and ethical responsibility, customer orientation and strategic advantage are the three most important motives, while customer recognition is the most serious barrier at present. This survey also shows that there are many differences between car part and machinery remanufacturers in China. For example, car part remanufacturers are more motivated by subsidies, at the same time, they are also more restricted by legislation, while lack of sales channels is a more serious barrier for the machinery remanufacturers. The differences exist partly due to the Chinese remanufacturing environment, for example the policies from different government departments that regulate the related industries. Suggestions for improving the remanufacturing industry, in particular from the policy makers’ perspective, are provided according to the survey results.

    Sustainability indicators for Small and Medium-sized Enterprises (SMEs) in the transition to provide Product-Service Systems (PSS)2015Ingår i: Procedia CIRP, ISSN 2212-8271, E-ISSN 2212-8271, Vol. 30, s. 149-154Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Product-Service Systems (PSS) were developed as more sustainable alternatives to traditional product sales, especially through better and more intensive use of materials. Some companies currently use this business model successfully, while others are still in the process of transforming to PSS. The change from providing a product to providing a service has proved to be rather difficult and actual sustainable benefits have been questioned.

    The research described in this paper was part of the ServINNOV project. The initial idea was to find out if, and how, indicators could help in the move to PSS. Indicators could give a clearer picture of the situation and monitor progress during the transition period. Indicators could also help companies focus on their core activities, and determine whether a PSS offering really helps them to become more sustainable. The study covers an overall view of sustainable indicators, with a focus on environmental issues.

    The research for this paper was carried out through both theoretical and empirical studies. Empirical findings were obtained from interviews with three companies, all of them working with PSS on different levels. The results will guide transition to provide more sustainable PSS.

    Toward Pull Remanufacturing: A Case Study on Material and Information Flow Uncertainties at a German Engine Remanufacturer2015Ingår i: Procedia CIRP, ISSN 2212-8271, E-ISSN 2212-8271, Vol. 26, s. 270-275Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Abstract Together with reuse and material recycling, remanufacturing has emerged as a sustainable approach for used products. Remanufacturing is more complex than manufacturing, due to the uncertainties in material and information flows inside the remanufacturing facility and along the product life-cycle. Therefore, some remanufacturers intend to use lean production principles and philosophies to deal with this complexity and to improve their operations. The aim of this paper is to identify reasons for possible material and information flow uncertainties and develop lean-inspired solution at a German engine remanufacturer. The empirical data were collected via a Material and Information Flow Analysis workshop. The reasons for missing, late, defective and non-available spare parts as well as disrupted, uneven, chaotic and inaccessible information flows are identified. Finally, a lean pull Kanban reordering system is suggested and recognized to be a proper solution to remanufacturing complexity.

    Towards facilitating circular product life-cycle information flow via remanufacturing2015Ingår i: Procedia CIRP, ISSN 2212-8271, E-ISSN 2212-8271, Vol. 29, s. 780-785Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    In order to achieve a sustainable development, circular economy approaches and circular material flows are explored in industry. However, circular information flows remain essentially unestablished. The aim of this paper is to: 1) explore categories and types of product life-cycle information available for remanufacturing; 2) identify constraints for efficient product life-cycle information flow via remanufacturing; and 3) propose initiatives to facilitate product life-cycle information flow via remanufacturing.

    Data was collected through workshops and interviews at five remanufacturing companies. An accumulated Sankey diagram illustrates product life-cycle information flow, losses and bottleneck. Based on the analysis, possible initiatives to facilitate efficient product life-cycle information flow via remanufacturing are presented.

    Automatic Dismantling Challenges in the Structural Design of LCD TVs2014Ingår i: Procedia CIRP, ISSN 2212-8271, E-ISSN 2212-8271, Vol. 15, s. 251-256Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Many liquid crystal display television sets (LCD TVs) end up in the waste stream today. The combination of hazardous materials such as mercury and liquid crystal, and the labor-intensive disassembly of LCD TVs, make the recycling process interesting to automate. However, since there are so many manufacturers the variation of LCD TVs is high, making automation a challenge. Todays most common automatic process utilizes shredders, resulting in degradation of recycled material and possible decontamination of machine equipment. This paper aims to investigate the challenges related to the structural design of LCD TVs for an automatic dismantling process for the recycling of LCD TVs. The challenges identified during the empirical study were related to the mixture of materials, inhomogeneous materials, thin design, separation of the different components and finding a suitable dismantling sequence without unnecessary removal of components.

    Challenges and Opportunities of Lean Remanufacturing2014Ingår i: International Journal of Automation Technology, ISSN 1881-7629, E-ISSN 1883-8022, Vol. 8, nr 5, s. 644-652Artikel, forskningsöversikt (Refereegranskat)
    Abstract [en]

    Lean philosophy, which promotes business excellence through continuous improvement, originates from the Japanese car manufacturer, Toyota’s Production System (TPS). An area where lean has not been fully explored is remanufacturing, a process that brings used products back to useful life. Remanufacturing is often a more complex process than manufacturing due to the uncertainty of process steps/time and part quality/quantity. This study explored remanufacturing by identifying its challenges and opportunities in becoming lean. The challenges of a lean remanufacturing system do not exceed its advantages. Although some researchers state that it is difficult or even impossible to apply lean principles to remanufacturing, this research utilizes lean as a continuous improvement philosophy that focuses on improving the remanufactured products’ quality, process lead times, and inventory levels.

    Environmental and economic benefits of Integrated Product Service Offerings quantified with real business cases2014Ingår i: Journal of Cleaner Production, ISSN 0959-6526, E-ISSN 1879-1786, Vol. 64, nr 1, s. 288-296Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    This paper quantifies environmental and economic benefits of the Integrated Product Service Offering (IPSO) in real practice from a life cycle perspective, in comparison with its corresponding product-sales type business as a reference. The paper also discusses the engineering activities contributing to those effects, as well as their enablers. To reach this goal, the paper investigates three IPSOs as real-life business cases in industry. Those cases are selected from different sectors and have different characteristics. In addition, the paper calculates and compares environmental impacts and economic costs of different offerings in each case through the use of Life Cycle Assessment and Life Cycle Costing, respectively. In all three cases, IPSOs had environmental and economic advantages in comparison with the product-sales type business. The engineering activities contributing to those advantages under IPSOs were recycling, remanufacturing, reuse, maintenance, and holistic planning and operation. The enablers were found to be high flexibility for realizing products and services and close relationships with relevant actors.

    Exploring inter-organizational relationships in automotive component remanufacturing2014Ingår i: Journal of Remanufacturing, ISSN 2210-4690, Vol. 4, nr 5Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    One of the industry sectors with the longest history in remanufacturing is the automotive industry. Remanufactured parts include brake calipers, engines, servo pumps and alternators. A big challenge for automotive component remanufacturers is to achieve a steady flow of cores (parts that are used for remanufacturing). This flow could be secured by making agreements with core suppliers, such as an original equipment manufacturer (OEM), a core broker or another actor in the market. The remanufacturer can also choose to collect the cores without closer collaboration with the core suppliers. One crucial aspect in choosing how to collect the cores is that it has to be lucrative.

    The aim of this paper is to explore how remanufacturers manage their inter-organizational relationships in the closed-loop supply chain. A case study was conducted within the European research project ‘CAN-REMAN’, and empirical data was collected from six participating companies within the project, all European small and medium-sized (SME) remanufacturers of automotive components. These companies were investigated, and their relationships, defined in earlier research with core suppliers, were evaluated.

    A key finding of the research is that the most problematic parameter with supplier relationships is to receive the ordered quantity of cores from the supplier. This parameter is continually ranked as one of the most important, and the participating companies also claim to have problems with it. A successful relationship and take-back system was pointed out by one of the companies to never be the owner of the actual cores, and only perform the remanufacturing activity (service) for an OEM. This new relationship, called reman-contract, is where the OEM owns the core and the remanufacturer just performs remanufacturing including some sorting and storing. It was found that with this kind of relationship, the ordered quantity of cores was fulfilled to a higher degree, and thus the challenge of achieving a steady flow of cores was met.

    Lean and green product development: two sides of the same coin?2014Ingår i: Journal of Cleaner Production, ISSN 0959-6526, E-ISSN 1879-1786, Vol. 85, s. 104-121Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    This paper compares and contrasts the lean product development (LPD) and green product development (GPD) concepts through a systematic literature review including 102 journal publications. The review resulted in 14 findings that were organised according to four dimensions: general, process, people and tools/techniques. A number of similarities between the concepts were found. For example, implementation of both concepts calls for a systems perspective where the dimensions of process-people-tools/techniques are linked holistically. Differences between the LPD and GPD concepts lie in: their goal and focus, value construct, process structure, performance metrics, and tools/techniques used. The findings do not unambiguously support that "green thinking is thinking lean" and consequently it cannot be argued that LPD and GPD are two sides of the same coin, meaning that LPD automatically leads to greener products or that GPD ensures improvements and efficiency in the product development process. However, it is reasonable to conclude that LPD and GPD belong to the same "currency". That is, the concepts share a number of similarities that indicate a synergistic relationship. This synergistic relationship has been accentuated by a nine propositions where the potential for cross-field learning is shown.

    Minimum Time for Material and Information Flows Analysis at a Forklift Truck Remanufacturer2014Ingår i: Proceedings of Sixth Swedish Production Symposium (SPS14), 2014Konferensbidrag (Övrigt vetenskapligt)
    Abstract [en]

    Material and information flows are often complex at remanufacturing companies. Minimum time for Material and Information Flows Analysis (MiniMifa) is a data collection workshop in which material and information flows’ challenges and improvement opportunities are investigated. By carrying the idea of Value Stream Mapping (VSM), MiniMifa turns to an act of cartography of industrial processes. After the workshop, companies have a holistic view of their processes, the current “pains” - challenges, and possible “painkillers” – improvement ideas, including lean-inspired solutions.

    This paper demonstrates a pilot MiniMifa at a forklift truck remanufacturer where a potential improvement in e.g. lead time reduction by 93% was discovered.

    Process concepts for semi-automatic dismantling of LCD televisions2014Ingår i: Procedia CIRP, ISSN 2212-8271, E-ISSN 2212-8271, Vol. 23, nr 2014, s. 270-275Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    There is a large variety of electrical and electronic equipment products, for example liquid crystal display television sets (LCD TVs), in the waste stream today. Many LCD TVs contain mercury, which is a challenge to treat at the recycling plants. Two current used processes to recycle LCD TVs are automated shredding and manual disassembly. This paper aims to present concepts for semi-automated dismantling processes for LCD TVs in order to achieve higher productivity and flexibility, and in turn increase the value of the recycled materials, improve the work environment for operators and remove mercury from the recycled materials. A literature review and two empirical studies were performed to be able to present a concept for dismantling direct illuminated LCD TVs. The process used a circular saw and/or a band saw to machine two cuts in LCD TVs to gain access to the mercury-containing cold cathode fluorescent lamps inside. This conceptual process is compared to the other processes found in the literature.

    Evaporation of Mercury from CCFLs during Recycling of LCD Television Sets2013Ingår i: Proceedings of EcoDesign 2013 International Symposium, 2013Konferensbidrag (Övrigt vetenskapligt)
    Abstract [en]

    The element mercury is one of the most hazardous substances known. Still, it is common in the air, water, soil and products we use in our daily life. LCD TVs is one of these products. To prevent the mercury in the LCD TVs from polluting the environment, the LCD TVs are recycled. This is done through automatic shredding or manual disassembly where the mercury can spread in the work environment, the process equipment or to the recycled material. This is due to broken CCFLs in the LCD TVs which contain the mercury. The aim of this paper is to investigate, through a literature review and an empirical study, the amount of mercury released into the work environment due to broken CCFLs from LCD TVs. In the literature review there were found the amount of mercury other researchers has found in CCFLs from LCD TVs, and also where the mercury was found. In the empirical study, the amount of mercury in a LCD due to broken CCFLs were measured and validates the results from other researcher and states that the mercury is difficult to predict.

    Exploring the Use of Product Life-Cycle Information in Two Value Chains Including Remanufacturing2013Konferensbidrag (Övrigt vetenskapligt)
    Abstract [en]

    Not many products are designed for remanufacturing. One of the reasons may be that the information flows to and from remanufacturers are not in level with the other information flows in the product life-cycle. In this paper, the information flows within two value chains including remanufacturing and PSS are investigated. The case studies show that the remanufacturing part of the value chain is not strongly included in the information flows in the product life-cycle. This means that valuable feedback about the product design and condition at end-of-life is neglected. Further, information feed forward, which could potentially make the remanufacturing process more efficient, is not satisfactorily implemented.

    Industrial cleaning with Qlean Water: a case study of printed circuit boards2013Ingår i: Journal of Cleaner Production, ISSN 0959-6526, E-ISSN 1879-1786, Vol. 47, s. 19-25Artikel i tidskrift (Refereegranskat)
    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.

    Remanufacturing: Challenges and Opportunities to be Lean2013Ingår i: Proceedings of EcoDesign 2013 International Symposium, 2013Konferensbidrag (Övrigt vetenskapligt)
    Abstract [en]

    The lean philosophy, which denotes business excellence through continuous improvement, originates from Japanese car manufacturer Toyota’s Production System (TPS). An area where lean is not fully explored is remanufacturing, a business that brings used products back to useful life. Remanufacturing is often a more complex process than manufacturing due to uncertainty of process steps/time and part quality/quantity.This paper has explored remanufacturing by revealing its challenges and opportunities to be lean. The identified challenges to work with lean do not overcome the advantages of a lean remanufacturing system. Even though some researches state that it is difficult or even impossible to apply lean to remanufacturing, this research recovers lean as a continuous improvement philosophy that not only works for manufacturing but also for remanufacturing.

    Reverse logistics challenges in remanufacturing of automotive mechatronics and electronic systems2013Ingår i: Journal of Remanufacturing, ISSN 2210-4690, Vol. 3, nr 2Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The remanufacturing industry as a whole and the automotive sector in particular have, over the years, proven to be beneficial to the environment and economically lucrative to the companies involved as well as to their customers. However, remanufacturing is associated with complicating characteristics, not least to mention the process of core acquisition.

    The automotive industry is one of the earliest adapters of remanufacturing. Parts like engines, brake calipers and servo pumps are common targets for remanufacturing. Modern cars also have several embedded computers, often referred to as electronic control units that communicate, share information and verify each other over a Controller Area Network (CAN) bus. Due to their high value and an increasing trend in the amount of CAN bus mechatronic devices, interest in their remanufacture is growing.

    Previous research has shown that it is preferable that the remanufacturer is an original equipment manufacturer (OEM), or has a close relation to the OEM, in order to achieve a well-performing remanufacturing business. In the automotive industry, there are many small and medium-sized enterprises (SMEs) that perform remanufacturing; for these enterprises, the challenges to have a profitable business are even harder. This is because the OEMs will not release any information on the communication parameters and therefore will not support the independent remanufacturing business. As a consequence, the independent remanufacturers, often SMEs, have to perform substantial reverse engineering.

    This paper presents a qualitative research study, based on interviews at SMEs regarding challenges linked to the reverse logistics of SMEs remanufacturing and trading used automotive mechatronic devices, to identify specific challenges concerning the collection phase of automotive mechatronic remanufacturing. Challenges previously identified by researchers are confirmed, additional challenges within the collection phase are recognized, and challenges expected to arise when remanufacturing and trading automotive electronic CAN bus mechatronic devices are identified. The major concern for the involved companies when commencing future challenges is the handling, transportation and storing of cores. Even though the cores today mainly consist of mechanical devices, these challenges are still present; they are expected, however, to become even more crucial when cores contain a higher degree of mechatronic devices.

    Product life-cycle information is used to improve a product’s performance over its life-cycle. The objective of this paper is to describe how information from the product life-cycle phases of design, manufacturing, use, service and end-of-life are used and handled in a value chain comprised of an international original equipment manufacturer with its suppliers and contracted remanufacturers. A case study of a value chain was conducted. The paper concludes that the information flows within the value chain studied are well-functioning; however the organizational structure seems to be a hindrance for full information exchange within the value chain.

    Design for automatic end-of-life processes2012Ingår i: Assembly Automation, ISSN 0144-5154, E-ISSN 1758-4078, Vol. 32, nr 4, s. 389-398Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Purpose – The purpose of this paper is to explore how manufacturers can develop automatic end-of-life processes facilitated by product design methods, e.g. design for disassembly, recycling and remanufacturing. Also to illustrate this kind of product and end-of-life process development while maintaining economic and environmental values. Here, the cases of toner cartridges and liquid crystal displays are the focus.

    Design/methodology/approach – The research methodology for this paper began with a literature study within the fields of design for automatic recycling and remanufacturing. It also includes the research performed at two different industrial companies using automation in their end-of-life processes. These companies were visited and interviewed several times, in order to understand their processes and what current problems they have in automation and product design.

    Findings – Design implications on the end-of-life have been explored, and in particular, three general product trends are in conflict with automatic disassembly: products are getting more complex and more heterogeneous; products are getting sleeker; and products are using more proprietary joints. In addition, the three industrial cases describe different problems in industry and how they can be tackled. Although many manufacturers have adapted the design principles of DFM and DFE, there is still much to improve when it comes to designing for the product's end-of-life processes. These kinds of adaptations should increase in importance over time as more and more products and components are remanufactured and/or material recycled. These kinds of adaptations will also encourage an increase of products passing through more resource efficient end-of-life options.

    Practical implications – Manufacturers reading what design problems other companies are experiencing and what solutions can be found would facilitate their own businesses and willingness to start their own and/or improve their existing manufacturing business. This could then be in shape developing products for end-of-life processes which also would encourage them to start their own end-of-life process facilities.

    Social implications – From a societal perspective, an increase in remanufactured products being placed on the market can increase the awareness and confidence of the consumers in non-new products made from non-virgin materials. This will increase the market for second-life products and bring about economics of scale, which in turn will alleviate the problem of depletion of resources.

    Originality/value – Most previous research in this area treats the different end-of-life processes separately; material recycling and product remanufacturing are but two examples. However, in this paper the focus is more on the overall view of end-of-life processes, along with examples of more specific and detailed end-of-life processes, such as disassembly and cleaning.
