Abstract: The system for processing waste includes both a fixed bed reactor and a fluidized bed reactor. The fixed bed reactor receives a first waste material and produces a first set of reaction products. The fluidized bed reactor is adapted for receiving a second waste material and producing a second set of reaction products. The first and second sets of reaction products may be selectively and adjustably mixed to produce a mixed set of reaction products. At least one cyclone separator receives the reaction products and separates and collects solids (waxes) from the product stream. At least one condenser receives the product stream and removes a condensable liquids from the product stream. The condensable liquids are collected, and a gas-liquid separator removes any remaining liquid from the gas stream. The remaining gas is then output as gaseous product.
