Development of innovative shredder residue separation and recycling system

Shredder residue is an unavoidable by-product of the treatment of end of life vehicles and household appliances. NKK has developed a new post-treatment process in which the residue is introduced in a bath of solvent made of hot tar and gives an overflow of plastics and metallic sediments. The recovered plastics can be injected into the blast furnace and the metallic parts recycled in the steel shop. This new process allows a high recycling rate of treated materials.
