Shredding Plant Configuration And Its Performance: Improving The Quality And Quantity Of The Products For Sustainable Development

Abstract:

Sustainable development requires the optimal use and recycling of the natural resources and wastes respectively. Recycling is the final productive use of end-of–life vehicles (ELVs), obsolete appliances, as well as industrial and municipal wastes. Wastes have become an important source for production of iron and steels, aluminium, copper, and other metals, as well as composites. Shredding and recycling plants are built to first shred the obsolete goods in pieces and then process the mixed scrap to recycle different metals and non-metals fractions for metallurgical and other industrial uses. Currently, the rate of recovery for obsolete goods in shredding and recycling plants, around the world, approximates to 75-80% and about 20-25% of the feed to the shredding and recycling plants is land-filled. However, social and economical concerns and new legislations together with the depletion of natural resources dictate for improving the recycling rate in an environmentally sound and economically viable manner. The new legislations for recycling rate of End of Life Vehicles (ELVs) and other obsoletes, especially in Europe, do not allow for such low recycling rate. The shredding plant facilities and their performances and possibilities for improving the quality and quantity of recycled products and protect environment through different scenarios are discussed. Furthermore, a case study for the result of improving the quality of ferrous scrap for metallurgical application in Sweden is presented.
