Abstract: Apparatus and method for reprocessing crushed organic waste products, such as rubber waste from worn car tires, by pyrolysis, the method including pyrolytically decomposing the crushed waste products in a pyrolysis bath which is one of a bed or a bath, and which has a temperature ranging from 450.degree. to 550.degree. C., into a mixture including volatilized constituents, liquid constituents, and solid constituents; collecting at least a part of the volatilized constituents from a gas space above the pyrolysis bath and transporting the collected volatilized constituents away from the pyrolysis bath for further utilization; and introducing a gas intermittently or continuously into the gas space above the pyrolysis bath.
