Environmental pollution is an ever found crux with the industrialized world although able to prevent or minimize the environmental pollution through some proper environmental management system. Product life cycle assessment (LCA) is a method of environmental assessment especially for the future plans, products and projects although it is able to assess only the environmental impacts through the product life cycle assessment (LCA). According to the methodology of the implementation of the product life cycle assessment (LCA), it is possible to continue at different stages of the relevant activities as necessary. The implementation of the assessment is done based on four key steps namely as goal and scope definition, inventory analysis, impact assessment and the interpretation. Under this assessment, basically it is expected to prevent the environmental impacts, mitigate the environmental impacts or find a solution for a future problem that relevant with the activity this is proposed.

Abstract The relentless pursuit of lower production costs causes companies to invest in more efficient production systems so that they can remain economically competitive, while the actions focusing on more sustainable operations from an environmental point of view are usually performed to meet the political government regulating environmental control. However, it is common for companies to focus their efforts to minimize the environmental impacts at an early stage of the product life cycle, neglecting sustainability management in the post-use phase. Given the context, this study seeks to develop sustainability indicators that can be used by the electronics industry to assess the level of practice and performance during production that are related to product recovery after the use phase, in order to better understand how companies are acting to reduce the environmental impacts of their products at the end of their life cycle. Initially, critical success factors related to environmental management of the product’s end-of-life are obtained. Then, some of those critical success factors are prioritized, giving rise to the indicators of sustainability used in the benchmarking method. Benchmarking was performed in electronics Brazilian companies, and the data was obtained by means of a questionnaire and interviews. It is concluded from the results that the proposed indicators are suitable for measuring the levels of practices and performance of the participant companies in environmental management at the end of the product life cycle as the indicators were able to portray faithfully the reality of each company.

Carbon Footprint Reduction

Interest in accounting for environmental impacts of products, processes, and systems during the design phase is increasing. Numerous studies have undertaken investigations for reducing environmental impacts across the product life cycle. Efforts have also been launched to quantify such impacts more accurately. Energy consumption and carbon footprint are among the most frequently adopted and investigated environmental performance metrics. The purpose of this paper is to serve two objectives — first, it provides a review of recent developments for carbon footprint reduction in manufacturing processes and supply chain operations. Second, a future vision is shared toward developing a method for reducing carbon footprint through simultaneous consideration of manufacturing processes and supply chain activities. The approach is demonstrated by developing analytical models for alternative manufacturing processes and supply chain networks associated in the manufacture of a bicycle pedal plate to realize its potential in assessing energy and GHG (greenhouse gas) emissions. The sustainable design and manufacturing research community should benefit from the review presented. In addition, a point of departure for concurrent consideration of multiple stages of the product life cycle for environmental performance is established for the research community to move current efforts forward in pursuit of environmental, economic, and social sustainability.

A manufacturer of any kind of product has to be in contrast to competitive to survive on market. A major point to win a customer over is the arrangements of costs. In investment goods industry asset cost are just the tip of the iceberg. Most of their costs accrue by use. Because of that it is important to overview the whole costs of the product life cycle. Product life cycle costs describe the cost of a product over its whole life. This includes all expenses from development, production and use to recycling and refers to manufacturer and customer equally. The majority of costs are determined in the stages of product development. As a manufacturer of complex investment goods (e.g. machine for production) the question of new development investments has to be answered. There are three important dimensions to consider. These dimensions concern the right part of product for improvement, the right kinds of costs and the owner of these costs. In detail they have to decide which part of product should be improved to get the main effect concerning reduction of life cycle costs. But in that case it is also important to know what kinds of costs of the chosen part have to be reduced (for example energy cost, cost for maintenance or repair). The third dimension in case of product life cycle costs aims at the owner of the cost, manufacturer or customer. This is a problem when new developments cause savings on one side but expenses for the other. In that context the best leverage of these combinations is searched for which means that exactly this kind of costs has to be identified, whose savings get the biggest benefit in relation to necessary expenses. This paper presents an approach to address this problem. For the pre-selection of possible functions established methods derived from product development are used in this context. Afterwards a procedure of quantification is presented. Calculation and rating of new defined management ratios provide the biggest leverage in order to reduce the product life cycle costs. This approach represents an instrument for manufacturer’s business of investment goods to make decisions about their future investments in the field of product development.
