Abstract
It is feared that lead is released to the environment from shredded residential bulky waste (RBW). To minimize the impact, the dominant source of lead should be identified and controlled. We determined lead leachability and lead content in various kinds of waste products in RBW. Consequently, the following conclusions were obtained. 1) Picture tubes of TV sets and printed circuit boards of home appliances have high lead content. 2) The total lead contents in RBW was estimated to be 2, 048 g/t (dry RBW), in which TV sets made the highest contribution (about 90%). 3) Removing TV sets from RBW stream, about seventy percent of the lead contained in landfilling residues could be reduced.
