- 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.

Material Efficiency Measurement: Empirical Investigation of Manufacturing Industry

- Improving material efficiency contributes to reduce the volume of industrial waste as well as resource consumption. However, less has been published addressing on what to measure for material efficiency in a manufacturing company. This paper presents the current practice of material efficiency performance indicators in a manufacturing context through a bottom-up approach. In addition to literature review, the empirical data was collected via a multiple case study at seven global manufacturing companies located in Sweden. The results show that existing material efficiency indicators are limited and are mainly measured as a cost or quality parameter rather than environment. The limited number of measurements relates to the fact that material efficiency is not considered as a central business in manufacturing companies and is managed by environmental department with limited correlation to operation. Additionally, these measurements do not aim to reduce waste volume or improve homogeneity of generated waste.

Present state analysis of business performance measurement systems in large manufacturing companies
- 2016

-
Conference paper (peer-reviewed)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.

Comparison of Four Environmental Assessment Tools in Swedish Manufacturing: A Case Study
- 2019

Journal article (peer-reviewed)abstract
- To achieve sustainable development goals, it is essential to include the industrial system. There are sufficient numbers of tools and methods for measuring, assessing and improving the quality, productivity and efficiency of production, but the number of tools and methods for environmental initiatives on the shop floor is rather low. Incorporating environmental considerations into production and performance management systems still generally involves a top-down approach aggregated for an entire manufacturing plant. Green lean studies have been attempting to fill this gap to some extent, but the lack of detailed methodologies and practical tools for environmental manufacturing improvement on the shop floor is still evident. This paper reports on the application of four environmental assessment tools commonly used among Swedish manufacturing companies—Green Performance Map (GPM), Environmental Value Stream Mapping (EVSM), Waste Flow Mapping (WFM), and Life Cycle Assessment (LCA)—to help practitioners and scholars to understand the different features of each tool, so in turn the right tool(s) can be selected according to particular questions and the industrial settings. Because there are some overlap and differences between the tools and a given tool may be more appropriate to a situation depending on the question posed, a combination of tools is suggested to embrace different types of data collection and analysis to include different environmental impacts for better prioritization and decision-making.

Material efficiency in manufacturing: swedish evidence on potential, barriers and strategies
- 2016
-
In: Journal of Cleaner Production. - : Elsevier BV. - 0959-6526 .- 1879-1786. ; 127, s. 438-450

Journal article (peer-reviewed)abstract
- Improved material efficiency is a key to improve the circular economy and capturing value in industry. Material efficiency reduces the generation of industrial waste, the extraction and consumption of resources, and energy demands and carbon emissions. However, material efficiency in the manufacturing sector, as a means of improving the recyclability, reusability, reduction and prevention of industrial waste, is little understood. This study aims to investigate, on a micro-level, further material efficiency improvement opportunities, barriers and strategies in selected manufacturing companies in Sweden, focusing on increasing waste segregation into high quality circulated raw material. Improvement opportunities at large global manufacturing companies are investigated; barriers hindering material efficiency improvement are identified and categorized at two levels; and strategies that have been deployed at manufacturing companies are reviewed. Empirical findings reveal (1) further potential for improving material efficiency through higher segregation of residual material from mixed and low quality fractions (on average, 26% of the content of combustible waste, in weight, was plastics; 8% and 6% were paper and cardboard, respectively); (2) the most influential barriers are within budgetary, information, management, employee, engineering, and communication clusters; (3) a lack of actual material efficiency strategy implementation in the manufacturing companies. According to our analysis, the majority of barriers are internal and originate within the manufacturing companies, therefore they can be managed (and eradicated if possible) with sufficient resources in terms of man hours, education and investment, better operational and environmental (waste) management, better internal communication and information sharing, and deployment of material efficiency strategies.

Material efficiency in manufacturing
- 2014
-
Conference paper (peer-reviewed)abstract
- Developments, industrialization and mass production have triggered rapid increase of raw material consumption and great volumes of industrial waste, while industrial waste management infrastructure has not been developed with the same pace. One mean in striving for industrial waste management is the management of process materials. This paper introduces the performance measure sorting rate for each segment of waste material, along with a method for sorting analysis to help improving overall material efficiency and industrial waste management. The results revealed that more than 50% of combustible bins’ content could be separately segregated as plastic, wood, paper, cardboard and bio-degradable.
