Abstract

An apparatus and method of waste treatment, particularly for the treatment of medical waste which is contained in plastic containers known as sharp safes. The apparatus has an inner cavity in which the waste is placeable and means for purging the cavity with stream before applying at least one form of electromagnetic radiation to the material within the cavity. The electromagnetic radiation can be infrared radiation and/or microwave radiation. The result of the waste treatment is a block of plastic encapsulating the medical waste which has been sterilised by the treatment.
