Abstract
A method and apparatus for use in processing waste materials of various kinds and for reclaiming useable by-product materials from the pyrolized waste materials. The waste materials to be pyrolized are efficiently dehydrated prior to their introduction into the pyrolysis retort using microwaves generated by a large microwave generator. After the waste material is dried, initial ignition is accomplished using a very high intensity laser beam. Laser ignition is continued until sufficient methane and other volatile gases are produced for burning in a burner unit to sustain the pyrolysis reaction.
