Zusammenfassung:	System and method for low temperature treatment of organic wastes containing potentially toxic concentrations of metals is described which comprises forming the waste material into pellets of preselected size, mixing the pellets with inert material, incrementally heating the mixture in air from about 200 DEG C. to about 600 DEG C. in order to oxidize the pellets to the corresponding ash containing the metals, collecting the ash, and combining the ash with inert material and binder to form a solidified compact for disposal.
