One way to recover and revalue a product is by remanufacturing, which is defined as the process of recovering a product to its original specifications, promoting the reuse of materials and improving its quality and functionality. However, the context of the remanufacturing industry faces difficulties and is considered unstable and inefficient if compared to manufacturing. In this sense, this paper aims to propose a cell layout based on lean concepts and adapted to the context of remanufacturing, aiming to minimize waste, reduce variability and thereby increase efficiency. The cell layout proposal was based on a literature review and researchers' practical experience in the area. This layout can provide the flexibility to handle the variations inherent in the context of remanufacturing, boosting product recovery and related environmental issues.展开更多

At present, making copper rod directly from recovered scrap copper and saving copper with aluminum have become topics of general interests in the Chinese cable industry. The quality of the copper conductors in the industry is declining, resulting in sharp decrease in the rate of qualified wire and cable products. More and more copper wires are drawn from the rods made directly from scrap copper. The manufacturers know well some of the wires or rods are unqualified products though, they continue to use or produce products not complying with standards in order to make profits. Now the consumption of copper-clad-aluminum and copper-clad-steel is growing gradually. In 2006, the consumption of copper-clad-aluminum in China amounted to ca. 5×104 t. But in some applications, neither the common understanding between buyer and supplier nor the results of feasibility study are achieved in the product orientation and technical/economic feasibility in terms of saving copper with aluminum. This paper presents the status-quo, problems arisen and suggestions in terms of making copper rod directly from recovered scrap copper and saving copper with aluminum, in a view to promote these two topics of general interests to go toward a virtuous circle.展开更多

And performance measurement is the key to implementing the supply chain. So it is necessary to evaluate the environmental performance of supply chain .According to the connotation of green supply chain and the standards of environmental management, this paper designs green performance measurement systems which is composed of four main factors such as waste emissions and exposure hazard, resource utilization, product recovery, and environmental reputation. And the authors delve deeply these factors so that it forms a two-level measurement system. Then the effect on the traditional performance measurement of supply chain is studied after taking greening to the supply chain leveL At last the authors apply the method of multi-level fuzzy judgment to the environmental performance measurement system. An example is given to show the judgment process.展开更多
