Abstract
Polyaromatic hydrocarbons are highly carcinogenic ubiquitous industrial wastes. In this Invention, concentrations of said wastes are diminished by microwave-assisted pyrolysis. Prior to exposure to microwave radiation, said wastes are covered with a non-combustible material consisting of loose, discrete particles like sand. Susceptors may be added to the waste prior to radiation. Volatiles from the process can be absorbed in a susceptor like granulated activated charcoal. When saturated, this granulated activated charcoal is added to the said wastes in a subsequent treatment.
