A French company specialised in metal recycling, is looking for a technology of valorisation of plastics contained in A.S.R (Automobile Shredder Residues), in light and heavy fractions. The need is to recover plastics compatible with the extrusion process out of a flow of mixed plastics, rubber, wood, foam and textiles. The products to be sorted are at the same time dark and light color. The technology should be available on the market or in a development phase.
