The invention relates to a reactor, a system and a method for treating and recovery of liquid and/or solid waste materials and by-products from industrial manufacturing and production operations, such as volatilizing organic compounds, by converting these materials into valuable materials which could be recycled and re-used, while at the same time minimizing any residue for final disposal to landfill or incineration. The invention includes an insulated, magnetic, electrically conductive reactor vessel [10] for receiving and treating a contaminated load, the reactor being characterized therein that it is operated under pyrolysis conditions and is heated by radio frequency induction of eddy currents into the reactor vessel [10].
