- Product design and development are essential for a circular transition. Circularity decisions, such as those concerning the type of material, assembly method, and expected lifespan, made during the early design stages will significantly influence a product’s quality, cost, esthetics, sustainability, and circularity performance over the product lifecycle. However, circularity is not often considered in the early stages of product design and development. This paper presents the development of the concept circularity evaluation tool (CCET), which aims to support the evaluation of alternative product concepts in terms of their circularity potential in the early stages of product design and development. The CCET was iteratively developed based on an extensive literature review of the success criteria for tool development, guidelines, and existing tools for circular product design and development and strong collaboration with manufacturing companies. The tool was tested and verified at four manufacturing companies in Nordic countries. The tool has been proven useful for evaluating the circularity of products and supportive in the decision-making process in the early stages of product design and development. © 2020 by the authors.

- Manufacturing Industry as an important part of European and Swedish economy faces new challenges with the daily growing global competition. An enabler of overcoming these challenges is a rapid transforming to a value-based focus. Investment in innovation tools for production system development is a crucial part of that focus which helps the companies to rapidly adapt their production systems to new changes. Those changes can be categorized to incremental and radical ones. In this research we studied the Obeya concept as a supporting tool for production system development with both of those approaches. It came from Toyota production system and is a big meeting space which facilitates communication and data visualization for a project team. Four lean companies have been studied to find the role of such spaces in production development. Results indicate a great opportunity for improving those spaces and their application to radical changes in production development projects.

Waste flow mapping to improve sustainability of waste management : A case study approach
- 2015

Tidskriftsartikel (refereegranskat)abstract
- Innovative, resource-efficient solutions and effective waste management systems capture value in business and contribute to sustainability. However, due to scattered waste management responsibilities in the vehicle industry and the orientation of operations management and lean tools, which mostly focus on lead-time and labour-time improvements, the requirement of a collaborative method to include material waste efficiency in operational development is identified. The main purpose of this research is to study how operations management and environmental management can be integrated on an operational level and include the waste management supply chain. Based on a literature review of environmental and operational improvement tools and principles, the gaps and needs in current practice were identified. A large case study implementing a waste flow mapping (WFM) method on a set of manufacturing sites revealed potentials in terms of reducing material losses and inefficiencies in the handling of materials and waste. Finally, the integrated WFM method was analysed with respect to the gaps and needs identified in the existing body of tools for operational and environmental improvement. The method combines lean manufacturing tools, such as value stream mapping with cleaner production and material flow cost accounting strategies. The empirical data showed that the WFM method is adequate for current state analysis of waste material efficiency potentials, especially when multiple organisations are involved. However, further development and specific methods are needed such as, for example, logistics inefficiencies, root cause analysis, implementation guidelines for best practice and systems for performance monitoring of actors.

Present state analysis of business performance measurement systems in large manufacturing companies

-
Konferensbidrag (refereegranskat)abstract
- The purpose of this article is to empirically investigate the present state of the performance measurement systems (PMS) at 7 sites of 6 different large Swedish manufacturing companies. The methodology has both a bottom-up and a top-down perspective. Important findings are that the PMSs are very similar in how they function but differ a lot in what is measured.

Individuals’ perception of which materials are most important to recycle

- In this study, we have asked respondents to rank ten different waste fractions that are both common in manufacturing industry and easily recognizable. The purpose of the study has been to clarify to what extent individuals are able to identify the waste fractions that are most important to recycle from an environmental perspective. The individuals’ perception has then been correlated with a life cycle assessment of the ten materials. In addition, the respondents were also asked to rank the fractions according to cost. The results show that metals are consistently considered most important to recycle, and plastics are commonly among the top five amongst the ten waste fractions together with glass. The cellulose based fractions, cotton, and compost are commonly rated low. In addition, there is a perceived correlation between the environmental and economic impact.

Critical Factors in Designing of Lean and Green Equipment
- 2014
-
Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- Designing production equipment considering lean and related sustainability requirements may be a major factor in achieving productiveness through lean implementation. The objective of the study is to investigate the impact of lean production requirements on equipment design and how the lean requirements affects early design phases and global footprint. Data collection method includes literature review and in depth interviews with equipment users. The results provide support to importance of considering green and lean requirements in designing of production equipment by introducing important lean design factors for production equipment. These factors are designing simple equipment, error-proofing, being portable and flexible, supporting one piece flow, supporting short setup time, easy and reliable maintenance, supporting the operator interface with machine, safety of the operator, supporting production processes and layouts, energy efficiency, easy to operate, minimum cost, visualization, straight flows, teamwork, standardization, quality assurance, using pervious experiences, easy to clean, and easy to control.

Tidskriftsartikel (refereegranskat)abstract
- This paper addresses the controversial gap between the environmental perspective and the cost perspective in a manufacturing context. The results of an empirical study on the heat treatment and phosphating processes performed by a manufacturing company indicate that implementing condition-based maintenance contributes not only to cost savings by preventing production losses and reducing equipment downtime but also to a more efficient use of resources by avoiding the generation of scraps and material wastage.

Tidskriftsartikel (refereegranskat)abstract
- Industry is a key player in the transition to a more sustainable society. Nevertheless, even though several efforts have been made in practice and in academia, more research is needed in relation to implementing sustainable solutions. Accordingly, the aim of the paper is to understand how manufacturing organisations can develop their operations to improve their way to respond to and manage change projects driven by environmental requirements. A multiple international case study is conducted, including nine case companies. The paper explores how the key factors for managing environmentally driven change can be integrated in the organisation, from the project – the core process – and the cultural perspective. A model is developed that can be used for operations managers to support their strategic planning of environmental change projects.
