NOVELTY - A resin foam ground product (2) is obtained by spraying the mixture of high pressure water of more than normal pressure, high pressure air or water and air to a resin foam.    USE - For regeneration of cushion material used as material for vehicle, furniture, bedding, daily necessaries and sound insulating material, and for solid fuel (all claimed).    ADVANTAGE - The resin foam ground product is rapidly recycled.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following:    (1) grinding of resin foam, which involves spraying the mixture of high pressure water of more than normal pressure, high pressure air or water and air to a resin foam;    (2) classification and disassembly of resin foam composite (1), which involves disassembling resin foam composite into resin foam ground product and auxiliary component (3) by spraying the mixture of high pressure water of more than normal pressure, high pressure air or water and air to the resin foam composite;    (3) classification and disassembling apparatus of resin foam composite, which has a disassembling apparatus, dismantling unit (4) to dismantle the resin foam ground product and auxiliary component by spraying the mixture of high pressure water of more than normal pressure, high pressure air or water and air and classification unit (5) to classify the resin foam ground product and auxiliary component;    (4) regenerated cushion material, which is obtained by using the resin foam ground product or auxiliary component; and    (5) solid fuel, which is produced by using the resin foam ground product.
