ABSTRACT:
A recycling method of wastes of an electrical appliance containing an article having a circuit soldered with parts soldered with a lead free solder. The method includes discriminating a first article having a circuit soldered with lead free parts from a second article having a circuit soldered with lead containing parts; recovering, grinding and melting each of the first and second articles to separate materials of the first article and materials of the second article; recycling reusable valuables contained in the materials of the first article and second article; and shredding a portion of the first and second article not containing the reusable valuables and burying/treating the portion at a stabilizing dumping ground or a controlled dumping ground for disposal.
