Abstract of the Disclosure, Waste such as combustible trash and prime garbage is mixed with rubber tires and shredded together to produce a compacted and combustible output product which can be used as a fuel or incinerated for further compacting. The process involves interengaging rotary feeder-cutter wheels mounted on counterrotating shafts to pull materials through a feed path while shredding with the aid of shredder blades interspersed between the wheels. Feeding mixing and conveying techniques through one or more shredder stages provide for attainment of high speed feed rates and handling of some degree solid debris such as steel belts in tires.
