FIELD: chemical recycling, particularly toxic material utilization.
SUBSTANCE: method involves passing materials through pyrolysis reactor for at least partial recovery of toxic chemicals at increased temperature in inert environment, which results in part of solid pyrolysus product precipitation on scrap metal particle surfaces. Flowable powder material is added to material to be recovered during material passage through pyrolisis reactor. The flowable powder material includes fine bodies with large summary areas. Major part of solid pyrolysus product precipitates on the fine bodies.
EFFECT: simplified scrap metal remelting, increased completeness of solid pyrolysus product utilization for repeatedly usage thereof.
