Abstract: A method of at least partially breaking down a material or product item or combination of material or product items. The method includes the steps of introducing said material or product item or combination of material or product items into a treatment vessel, introducing at least one working fluid into the treatment vessel, repeatedly increasing pressure on the material or product item or combination of material or product items in said treatment vessel to above atmospheric pressure and then subsequently depressurising the material or product item or combination of material or product items in the treatment vessel to achieve a pressure reduction in the vessel to effect at least partial breakdown of said material or product item or combination of material or product items.

Abstract: An apparatus to effect at least partial breakdown of a discrete material or product item or a combination of discrete material or product items. The apparatus includes a treatment vessel in which the discrete material or product item or combination of discrete material or product items are located for treatment. There is at least one entry for introduction of at least one working fluid, at least one pressurisation arrangement to increase pressure on the material or product item or combination of material or product items within the treatment vessel. At least one decompression arrangement to rapidly reduce the pressure on the material or product item or combination of material or product items within the treatment vessel may also be provided. The at least one pressurisation arrangement and the at least one decompression arrangement are operable to cause repeated pressurisation and rapid decompression on the material or product item or combination of material or product items within the treatment vessel.
