Abstract: An improved method for pyrolyzing waste materials and recovering useful chemical and energy rich materials therefrom. The apparatus of the invention includes a specially designed, rotatable combustion chamber and embodies a highly novel means for withdrawing a portion of the combustion gases generated by the pyrolysis of the waste materials, mixing these gases with preheated air in carefully controlled proportions and then using the highly combustible gaseous mixture thus formed to sustain pyrolysis within the combustion chamber.
