Abstract
Disclosed is a method of fragmenting a discrete waste product item or a combination of discrete waste product items involving introducing the discrete waste product item or combination of discrete waste product items into a pressure vessel, subjecting the item or items to an atmosphere of superheated steam in the vessel of at least 0.5 bar above atmospheric pressure, subsequently decompressing the vessel to achieve a pressure reduction of at least 0.5 bar in at most 5 seconds, and repeating the steps to effect fragmentation of the waste product item or combination of waste product items.
