ABSTRACT:
This Hazardous Waste Reclamation process pyrolyzes hazardous waste such as PCB (polychloro-biphenyl) in a closed system in a molten alloy, containing some aluminum, at a minimum of 800 degrees C. to form activated carbon that is recovered from the circulating exit gas stream and an impure alloy ingot containing unreacted metals and metal salts that are saleable to a metal processor as a high grade ore. The composition of the alloy may be varied to assure maximum reaction to nontoxic alloy salts that remain in the ingot.
