This model plant, recently constructed for recovering ferrous and non-ferrous metals from waste home appliances, was designed in its main systems by the Association for the Promotion of Recycling of Home Appliances and in its cryogenic systems by the Agency of Industrial Science and Technology. The methods used in the main systems were shredding with ballistic separation, air classification, magnetic separation, screening and comb-type picking, and the methods used in the cryogenic systems were shearing, precooling, dipping in liquid nitrogen, shredding and magnetic separation. Recovery fractions of metals in this plant were projected at 95% for iron and 70% for copper. The economic evaluation of this plant indicated that the running cost, exclusive of capital charges, was almost equal to the revenues from sales of the products in the case of the treatment of three waste home appliances consisting, approximately, of 20 per cent refrigerators, 30 per cent washing machines and 50 per cent television sets.
