Patent ID: 8030441

Claim:
A method for rendering environmentally inert toxic substances in residual material from a production of agglomerated material, the method comprising the step of: (a) subjecting the residual material to dielectric heating using radiofrequency electromagnetic waves having a frequency of less than 300 MHz; the residual material comprising an uncompacted mixture of aggregates of the agglomerated material, a hardenable resin, and a catalyst; the hardenable resin being mixed with the aggregates and being dissolved in an organic solvent; the toxic substances comprising a resin and a styrene; (b) raising a temperature of the residual material by dielectric heating in step (a) to 100-200 degrees Centigrade; and (c) maintaining the temperature in step (b) between 100-200 degrees Centigrade for 15-20 minutes catalyzing the styrene and the resin to render the toxic substances environmentally inert.
