Total recovery of residue from auto shredders

Research and development of a process for recovering and recycling materials coming from end-of-life car shredding residue that nowadays go to landfill, against the background of eu directive 2000/53/ce and the kyoto agreement.

Vehicles and cars are basically an integrated junction of metal parts, approximately 71% of the weight of the car, where 66% is iron and 5% non-ferrous; the rest is plastics, rubber, glass, paint and others. Referring back to the total amount of plastic present in car manufacturing, approximately 29% of the weight, we should mention that several studies (APME) are projecting that only 50% of the car scrapped in 2015 will see proper recycling. Something to be highlighted is the presence of stones, rocks and dirty sand in car wrecks. With all this, it seems that the end-of-life vehicle Directive (2000/53/CE) recycling targets are very ambitious, 85% for 2006 and 95% for 2015. Nowadays, end-of-life vehicle recycling goes from depollution and reuse of old spare parts to final shredding of car wrecks in a hammer mill, where shredded iron and other non-ferrous metal are recovered by means of different equipment in several processes. The rest, i.e. mixed plastics, rubber, rocks and a small fraction of metals, are not properly recovered or go to landfill. In spite of the history in metal recycling, real industrial experience is showing that recent new developments based on metal detection sensors, X-ray and other systems are improving possibilities in metal recovery rates, much more than few years ago. With all this, the main purpose of this project is to define a process, combining several different technologies, linked in an industrial layout, in order to drive end-of-life car shredder residue to total material recovery based on: a. Maximising metal recovery rates to 99% of the total amount. b. Obtaining an 'organic fraction', selected mixed plastics, rubber and textile, a reduced size and ready to be used as a substitution fuel in big industrial combustion lines (cement kilns, etc.); getting characteristics similar to 'regular fuels' currently used, for instance coke. c. Concentrating a mineral fraction, from rocks etc., with a high silica and calcium concentration, able to be used in the ceramic industry and other similar industries. Keywords: car residue recycling.
