The issue of automobile recyclability is a problem with complex ramifications for car makers world-wide. Confronted with increasingly stringent fuel economy, emissions, and safety standards, recyclability is an attribute which can limit the ability of the automaker to meet these other goals economically. Nevertheless, social and political pressures upon the industry require that it responds to ...

level, the primary decisions for a remelter involve composing alloy batches by carefully selecting and mixing various amounts of scrap and primary materials. Sorting provides added flexibility as well as complexity to these decisions by affording the secondary processor the opportunity to upgrade the materials which they have at hand. With sorting, the set of operational decisions include what ...

This paper describes the characterization and leaching behaviour of precious metal present from electronics scrap to obtain liquor which can be treated through hydrometallurgical techniques to purify the metals. The results of this study points out the technical feasibility of the recovery of the metals. The blank sample was characterized by X-ray florescence. This paper will also present the r...

The “zipper” data type provides the ability for editing tree shaped data in a pure functional setting and has found many uses and applications. However the traditional zipper has two major limitations. First, requires a significant amount of boilerplate code to implement. Second, it can only operate on homogeneous data types. Data structures where there are multiple node types are beyond the ra...

Keeping materials in use for a long time is key to reducing primary material demand and environmental impacts of resource use. Recycling yields metals should only be limited by thermodynamically unavoidable losses the remelting processes well-defined scraps. In practice, however, additional dissipative occur due incomplete collection end-of-life products, insufficient waste sorting, contaminate...

Advanced digital solutions are increasingly introduced into manufacturing systems to make them more intelligent. Intelligent Waste Management Systems in industries allow for data collection and analysis better-informed decisions, monitor manage processes remotely, improve waste management. In many industries, scrap is collected large containers located on the factory floor, usually close its so...

Recycling metal scrap is an effort to save The earth from pollution, meanwhile in the process of recycling usually it took a lot water cooling such high temperature. purpose this study was identified quality reservoir and river that indicated receiving overflow when rainy season. conducted October November 2020 at Melting Scrap Factory around industrial zone. by taking sample for analysis spot ...

Platinum Group Metals have become indispensable in modern industrial society and the demand for PGMs has greatly increased. An in-depth quantitative analysis of PGM applications, lifecycle structure, deficits and optimisation potential in Germany has been carried out by Umicore Precious Metals Refining and ÖkoInstitute. Besides detailed insights into one of the more opaque metal markets, the st...
