Redesign of a component based on ecodesign practices: environmental impact and cost reduction achievements

This paper focuses on ecodesign and its application in the footwear industry aiming to identify how the ecodesign can be applied to the redesign of a shoe component in order to minimize the environmental impact and simultaneously reduce costs of production and assembling. The factors that influence the use of ecodesign, the benefits and the difficulties were also investigated. A longitudinal case study was developed in a company that produces shoe stiffeners. The process of ecodesign implementation and the practices of ecodesign considered during the product redesign were analyzed. A cost reduction of about 10% was observed (in relation to the use of natural fibers and polymers in its composition-31% of biomass and 69% of fossil material). Toxic materials were completely eliminated and a reduction of energy consumption was also noticed (during the injection process). The main contributions of this study are: ecodesign constructs to be further researched the conjoint analysis of technological ability and market potential in a redesign project, and the requirements to gain managerial support for a redesign project.     

Integrating carbon footprint into supply chain management: the case of Hyundai Motor Company (HMC) in the automobile industry

The purpose of this paper is to improve our understanding of carbon footprint within the context of automobile supply chain management. The case study approach is employed as a research method. Primary data were collected through site visits and extensive interviews with HMC’s corporate and plant management. First, identification and measurement of direct and indirect carbon footprint is critical for mitigating supply chain risks. Second, setting the system boundary of measurement is another important issue to integrate the issue of carbon footprint into supply chain management. Third, developing a map of product carbon footprint facilitates identification and measurement of carbon emissions across the supply chain. Companies today operate in a carbon-constrained world. In particular, the automobile industry is under pressure to take a close look at its product carbon footprint. Managing the downstream consequences of the use of its products and inputs from upstream suppliers is critical for developing carbon risk-mitigated supply chain management. This paper is of benefit to academics and managers by providing a new way to integrate carbon emissions in supply chain management. Since climate change and carbon footprint present challenges to many industries, increasing our understanding of how to integrate carbon footprint in supply chain management is necessary, but has seen little research in the automobile industry.     

Expert views on environmental impacts and their measurementin the forest industry

The paper argues that corporate environmental management should be based on significant environmental aspects that result in significant environmental impacts. The Finnish forest industry has substantially reduced its emissions but, being heavy industry, it still causes significant environmental impacts. This paper presents expert views on environmental impacts and their measurement. They were gathered through semi-structured theme interviews. The most frequently mentioned environmental impacts and significant environmental impacts related to water, energy and air. Positive environmental impacts resulted from recycling, forest industry products and use of energy. Traditional emission measurement was considered a well-measured issue. The target subjects of the measurement and especially environmental impact measurement require improvement. The contribution of this research is concerned with the development of measurement and two issues arising from the research are emphasised. First, environmental impact measurement should be further developed. Second, the measurement of the production chain that is physically outside the boundaries of forest industry mills should also be developed.     

Emerging design strategies in sustainable production and consumption of textiles and clothing

This study contributes to current knowledge of sustainability in textile and clothing production and consumption. When the textile and clothing industry aims to promote sustainability, the main change factors have been linked to eco-materials and ethical issues in production. At present, however, business models are mainly linked with a large volume of sales and production. Although industrial development has moved toward smaller environmental impact, production as well as consumption has increased to levels where the benefits of technological development are reduced. A change is thus needed to reach a systemic transformation, not only in production but also in consumption. The aim of this paper is to open up the discussion on opportunities for radical change in this industry. The paper presents ways to rethink and redesign business in the textile and clothing field by offering an overview on several design strategies that exist today in niche markets. Furthermore we evaluate how interested consumers are in these design strategies and discuss the opportunities these design approaches offer to sustainable development through new value creation.
