  • New perspectives for green and sustainable chemistry and engineering : approaches from sustainable resource and energy use, management, and transformation
  • 2018
  • Ingår i: Journal of Cleaner Production. - : Elsevier. - 0959-6526 .- 1879-1786. ; 172, s. 227-232

    • The special volume on green and sustainable chemistry and engineering has fourteen papers that were considered relevant to the present day issues and discussion, such as adequate use of raw materials and efficient energy, besides considering renewable sources for materials and energy; and changing economical canons towards circular economy. Businesses, governments and Society are facing a number of challenges to tread the sustainability path and provide wellbeing for future generations. This special volume relevance provides discussions and contributions to foster that desirable future. Chemicals are ubiquitous in everyday activities. Their widespread presence provides benefits to societies’ wellbeing, but can have some deleterious effects. To counteract such effect, green engineering and sustainable assessment in industrial processes have been gathering momentum in the last thirty years. Green chemistry, green engineering, eco-efficiency, and sustainability are becoming a necessity for assessing and managing products and processes in the chemical industry. This special volume presents fourteen articles related to sustainable resource and energy use (five articles), circular economy (one article), cleaner production and sustainable process assessment (five article), and innovation in chemical products (three articles). Green and sustainable chemistry, as well as sustainable chemical engineering and renewable energy sources are required to foster and consolidate a transition towards more sustainable societies. This special volume present current trends in chemistry and chemical engineering, such as sustainable resource and energy use, circular economy, cleaner production and sustainable process assessment, and innovation in chemical products. This special volume provides insights in this direction and complementing other efforts towards such transition.

  • What if everyone becomes a sharer? A quantification of the environmental impact of access-based consumption for household laundry activities
  • 2020
  • Ingår i: Resources, Conservation and Recycling. - : Elsevier BV. - 0921-3449 .- 1879-0658. ; 158
  • Tidskriftsartikel (refereegranskat)abstract
    • In order to meet the EU's climate and resource efficiency targets, changes in our daily-life behaviours, as well as business models, are urgently necessary. More insights are needed to make real changes based on research with a systems perspective. We developed a system dynamics model to analyse the environmental benefits of a transition from ownership-based to access-based household laundry activities. The model considers demographic, technological and behavioural aspects and thereby assesses the environmental impact of laundry activities. The model is applied to the Swedish as well as the European context and allows cross-country comparisons. The results indicate a significant potential of the sharing economy. The higher utilisation of shared machines and extended lifespans of the machines can cut greenhouse gas emissions by a third and lower raw material usage overall and lower primary raw material in production due to higher recycling rates. The carbon intensity of the energy mix is a crucial factor for the environmental consequences that arise through changes in energy usage due to sharing economy practices. This case study shows the value of adopting policies that could promote sharing and extended life spans.

  • Failure analysis method for enhancing circularity through systems perspective
  • 2021
  • Ingår i: Journal of Industrial Ecology. - : Wiley. - 1530-9290 .- 1088-1980. ; 25:3, s. 544-562
  • Tidskriftsartikel (refereegranskat)abstract
    • Recently, a circular economy has attracted global attention as an approach for addressing material security and resource-efficiency issues. As our societies shift toward a circular economy, manufacturers need to not only produce environmentally conscious products but to also realize reliable systems that will ensure the closure of the loops of the products, components, and materials. To do so, early-stage design is crucial to effectively and efficiently detect possible failures and then take adequate countermeasures against them. Although a few methods of failure analysis have been proposed to address environmental issues, these methods have failed to consider the cause–effect relationships among failures. This will hinder manufacturers from identifying core problems that should be addressed in a given system. Therefore, this study extends failure mode and effect analysis, which is an engineering technique used to address potential failures, by addressing the entire system reliability in relation to circularity. As a result of a case study of a manufacturer aiming to increase circularity with their products on the market, we revealed that the proposed method is useful in the early stage of design to (a) identify failure modes where effects are largely given to or received from other failures, (b) develop countermeasures effectively by addressing root causes of failures, and (c) find an opportunity to collaborate with external actors.

  • Interactions of governmental policies and business models for a circular economy: A systematic literature review
  • 2022
  • Ingår i: Journal of Cleaner Production. - : Elsevier BV. - 0959-6526 .- 1879-1786. ; 337
  • Forskningsöversikt (refereegranskat)abstract
    • Governmental policies and business models are considered key elements for a transition to a circular economy. In current literature, there is a lack of understanding on how these two elements interact and how this understanding is used to accelerate the realisation of a circular economy. We shed light on this issue by conducting a systematic review of the literature in combination with a literature synthesis that looked in particular at interactions between governmental policies and business models not limited to a circular economy. We systematised the findings and then applied them to a circular economy context. The results show that there is a multitude of possible interactions between governmental policies and business models. The most commonly studied interaction is between command-and-control regulations and the value proposition element of business models. Soft policy measures like information- or communication-based policies or support mechanisms are less studied. Other findings suggest that there are certain types of dynamics which are useful to understand for policymakers and business model designers alike. A few examples of the synthesised insights are i) entrepreneurs may optimise their circular business models to exploit the policy framework, ii) technologies may lead to circular business model innovation forcing policymakers to adapt, and iii) policymakers may pay special attention to the needs of circular business models and support their competitiveness.

  • A Multi-Criteria Evaluation Method of Product-Level Circularity Strategies
  • 2020
  • Ingår i: Sustainability. - : MDPI. - 2071-1050. ; 12:12
  • Tidskriftsartikel (refereegranskat)abstract
    • The circular economy (CE) can drive sustainability. For companies to select and implement circularity strategies, they need to evaluate and compare the performance of these strategies both in terms of progress towards CE but also based on their feasibility and business outcomes. However, evaluation methods for circularity strategies at the product level are lacking. Therefore, this research proposes a multi-criteria evaluation method of circularity strategies at the product level which can be used by business decision-makers to evaluate and compare the initial business of the company, transformative and future circularity strategies. This multi-criteria evaluation method aims to assist business decision-makers to identify a preferred strategy by linking together a wide variety of criteria, i.e., environmental, economic, social, legislative, technical, and business, as well as by proposing relevant indicators that take into consideration, where possible, the life cycle perspective. It also allows for flexibility so that criteria, sub-criteria, and weighing factors can be altered by the business decision-makers to fit the needs of their specific case or product. Two illustrative examples based on case companies are presented to verify and illustrate the proposed method.

  • Interdisciplinary Insights Found for Product/Service System Design
  • 2016
  • Ingår i: DS 84: PROCEEDINGS OF THE DESIGN 2016 14TH INTERNATIONAL DESIGN CONFERENCE, VOLS 1-4. - : The Design Society. ; , s. 137-144
  • Konferensbidrag (refereegranskat)abstract
    • Product/Service System (PSS) is a different way of fulfilling customer needs by providing a bundle of products and services. PSS is by nature an interdisciplinary field of research that needs collaboration across disciplines. This research paper investigates how much interdisciplinary research has been carried in terms of insights used between two important disciplines, namely, Engineering Design and Industrial Marketing. The results show that few insights have been used across disciplines which shows a gap for further research.

  • State of the Art of Design Methods for Resource Efficient and Effective Solutions : Report from “Product and Service Design Methods for REES” Project of Mistra REES program
  • 2017
  • Rapport (övrigt vetenskapligt/konstnärligt)abstract
    • This document reports on the results of work packages (WPs) 2.1 and 2.2 in Project 2 (Product and Service Design Methods for REES, i.e. resource efficient and effective solutions) of the Mistra REES program (www.mistrarees.se). WP 2.1 and WP 2.2 aim at documenting current use of design methods and deriving requirements for design methods, respectively. The document only covers results from the scientific literature review, while other reports to be developed will cover results, for instance, from the interview study and the design session with industry partners in the Mistra REES consortium. The results of the literature review will be a foundation for WP 2.3, which aims at developing new design methods. Note that methods here include frameworks, tools, and support for designers.The document describes current use (i.e., “as‐is” status) of product and service design methods when designing REES, as well as requirements for product and service design methods for REES (i.e., information soon‐to‐be). Both of these are results of analysis in different phases of an early phase of design for REES. Those phases consist of requirement specification, conceptual design, and analysis and evaluation, which can be ordered temporally along the design process.From the overall analysis, found is a lack of insights about methods for designing REES, although potentially useful methods are available. This means advancement of knowledge is insufficient for industry within the subject, which is relatively new. It may also mean the developed methods are not precisely according to the needs of companies. This shows a high potential of developing new methods in the rest of the project.More specifically, in the requirement specification, the literature shows that potentially useful methods include QFD (Quality Function Deployment), the Taguchi method, the Kano model, and data mining, among others. In the conceptual design, numerous methods exist, and most of them were developed in an older context, where REES was not as relevant as today. Those methods include DfX methods (X denotes cost, assembly, etc.), the functional block diagram, the checklist, morphological analysis, and the Fishbone Diagram. Only a few seem to be used widely in industry today. In the analysis and evaluation, available methods include Lifecycle Simulation, Lifecycle Costing, multi‐criteria decision making, and the Analytical Hierarchy Process. Most of the methods or tools available specialise in one area. This is a problem when developing an integrated offering of products and services, because designers need to have a holistic perspective for that.Regarding requirements for methods to be developed, the authors analysed literature as follows. In the requirement specification, requirements originating from multiple aspects and actors need to be taken into account. Since an enormous amount of data and information can be collected from products and by technologies implemented today, a huge opportunity is presented for enhancing requirement specification. Yet, there seems to be little insights to take this opportunity. In conceptual design, it is important to identify and involve relevant actors as well as their requirements according to a number of scientific reports. Especially, interaction between the relevant actors seems to be critical to be implemented. In analysis and evaluation, various pieces of earlier research works recommend different features to be implemented in methods. These features include visualization of information and information flows, graphical user interface, multiple users’ participation, and ability to handle environmental information, uncertainty and risk.

  • Support for Designing Resource Efficient and Effective Solutions: Current Use and Requirements by Swedish Industry : Report from “Product and Service Design Support for REES” Project of Mistra REES program
  • 2017
  • Rapport (övrigt vetenskapligt/konstnärligt)abstract
    • This document reports on the results of work packages (WPs) 2.1 and 2.2 in Project 2 (Product and Service Design Support for REES, i.e. resource efficient and effective solutions) of the Mistra REES program (www.mistrarees.se). WP 2.1 and WP 2.2 aim at documenting current use of design support and deriving requirements for design support, respectively. The document only covers results from interviews with companies, while the other reports will cover results, for instance, from scientific literature review (ISRN: LIU‐IEI‐RR‐‐17/00264—SE) and the design session with industry partners in the Mistra REES consortium. The results of this research into industrial practice will be a foundation for WP 2.3, which aims at developing new design support for designers.The document describes current use (i.e., “as‐is” status) of product and service design support when designing REES, as well as requirements for product and service design support for REES (i.e., information soon‐to‐be). Both of these are results of analysis in different phases of an early phase of design for REES. Those phases consist of requirement specification, conceptual design, and analysis and evaluation, which can be ordered temporally along the design process.Eight Sweden‐based companies that provide products and services in different sectors and work on resource efficiency participated in the interviews. They vary in terms of the size: from small to large. 24 individual interviews were conducted in total with the length being between 54 and 117 minutes (with two additional shorter follow up interviews via phone/skype). The 24 interviews were carried out all with face to face between May and July, 2016. The result from each company is described per section in this report, while cross‐company analysis will be made in a separate document.

  • Analysis and evaluation in the early stages of designing resource efficient offerings : A comparison among large companies and small and medium enterprises
  • 2019
  • Ingår i: Proceedings of the Design Society. - Cambridge University Press : Cambridge University Press (CUP). ; , s. 3161-3170
  • Konferensbidrag (refereegranskat)abstract
    • In Europe there is a common vision to transform the economy into a sustainable one by 2050 which among other changes, calls for companies to address their offerings in a more resource-efficient manner. Therefore, efforts to provide design support namely, methods, guidelines and tools to specifically address natural resources and impact of products and services have been increasing. Moreover, companies of all sizes should integrate environmental concerns as early as possible to select profitable and environmentally sound offerings. However, knowledge of the analysis and evaluation of resourceefficient offerings seems currently insufficient especially with regards to similarities and differences among different company sizes. In this paper, the study of eight case companies: 3 large companies and 5 SMEs, shows how industry addresses the analysis and evaluation of their offerings. Commonalities among SMEs and large companies include decisions made by strategic or managerial boards, the use of mock-ups and project management skills, among others. These findings could help academics in providing relevant, useful and usable support to industry.

  • Requirements for REES design support : a survey among large companies and SMEs
  • 2018
  • Rapport (övrigt vetenskapligt/konstnärligt)abstract
    • This report presents the results of a survey carried out during 2017-2018 among 11 different companies as part of the REES programme (www.mistrarees.se) work package (WP) 2.2 of Project 2 (the project concerning design in the programme). The objective of the survey was to identify the most important requirements for design support that is being developed for REES designers in the manufacturing industry. The survey comprises results from a total of 25 participants from 5 SMEs and 6 large companies, which included 8 participants from SMEs and 17 from large companies. This classification was made according to the EU commission (2015) definition of SMEs (< 250 employees and ≤ EUR 50 million in annual turnover). The results presented are divided into Section 1 where an overview of the survey and the method is presented and section 2 results, where consolidated data and comparison between large companies and SMES is provided.
