Presented is a method and apparatus for converting both organic and inorganic materials into more desirable products by the expedient of breaking down these materials into their stable molecular constituents and reforming them into more desirable substances. The process involves the use of two chambers. Blended solid and fluid wastes are augered into the first chamber and agitated, preferably by rotating the chamber so that the waste tumbles over internal fins, while a heat gradient is applied. Carbon and inorganic solid wastes are removed from the system and fluid wastes passed to a second chamber where they are again subjected to a heat gradient. Effluents are recovered and condensed. Electromagnetic radiation, preferably from microwaves, and/or lasers, masers or ultrasonic energy is applied to the wastes in both chambers. Liberal use of catalysts is made in the chambers. In addition, the augering system is based on the use of two, counter-rotating, inter-lapped, symmetric augers for positive feed of materials.
