Garbage and waste of all types that includes or comprises organic matter, particularly including medical waste, plastics, paper, food waste, animal by-products, and the like, can be economically recycled into petroleum products, including oil. Machinery performs a method that mimics natural processes but accomplishes the task in minutes, at rates of about 15 tons per day in a typical processing machine, rather than taking hundreds of thousands of years in nature. The process and apparatus of the invention may chop the waste into small pieces, under negative pressure if appropriate, and then pass the waste into first and then second augers for compression and heating. Destructive distillation occurs, in which large molecular weight hydrocarbons and petrochemicals are heated by hot oil passing through the hollow shaft and by circulating hot, dense, hard material, such as steel balls or fragments or hard rock pieces and such, under pressure with steam, to produce low molecular weight hydrocarbons. The volatile hydrocarbons are released through a pressure relief valve, into a column of catalyst material, and then to a heat exchanger, which cools the gases to condensation temperatures of water and oil. Gases remaining, such as methane, are passed to a furnace or other use, and the water and oil are separated. The hot items used to put heat into the compressed material in the first stage auger are retrieved after processing is completed and then reheated and cycled back into the first stage auger.
