Public opinion polls consistently show a high percentage of the U.S. population, typically more than 75 percent, consider themselves to be environmentalists. One of the issues that environmentalists feel most strongly about is recycling. In many communities there is an almost religious fervor surrounding recycling. Unfortunately, there also appears to be widespread misunderstanding regarding th...

sciencemag.org SCIENCE to access higher-purity polymer feedstocks will be required to minimize the dependence on consumer separation of materials manually during disposal for collection. Strategies for recycling mixed or contaminated feedstocks are also needed. Current compatibilizers must be customized for a given waste composition, which is not going to be practical on the large scale. More v...

Improved recycling of end-of-life vehicles (ELVs) may serve as an important strategy to address resource security risks related to increased global demand for scarce metals. However, in-depth knowledge of the magnitude and fate of such metals entering ELV recycling is lacking. This paper quantifies input of 25 scarce metals to Swedish ELV recycling, and estimates the extent to which they are re...

Materials are a strategic resource and the increasing prices for metals call for an optimized materials use. The prices for materials due to demands, growing faster than the production of virgin material, have put recycling in focus. The mindset “material hygiene” is a pedagogical concept aimed at managing compromises necessary to optimize materials use in products. Consideration to the entire ...

At the present, auto part industries have become higher challenge in strategy market. As this consequence, manufacturers need to have better response to customers in terms of quality, cost, and delivery time. Moreover, they need to have a good management in factory to comply with international standard maximum capacity and lower cost. This would lead companies to have to order standard part fro...

In order to fulfill the objectives of environmental protection, today's focus on quantitative recycling rates must be amended by a more qualitative approach. Because modern products represent a mix of numerous and sometimes hazardous substances, ways must be explored to remove detrimental substances during recycling and to establish "clean cycles". On the one hand, such a "clean cycle" strategy...
