Method for preparing biogenic waste for composting by shredding and heating in batches in container with a screw drive shredding blade

摘要

A method for preparing biogenic waste for composting has the waste fed into a container (1) from a storage bunker and shredded by a rotating screw type blade (3) to increase the surface area. Heat is applied before, during or after the shredding to heat the waste to about 36 deg. C. Heat is supplied by a heating element and by waste heat from the shredder motor. The prepared batch of waste is discharged via a port.
