To provide a process for treating coating wastes which hampers the increase of industrial wastes and the generation of large amount of CO2 and is inexpensively and economically realized, wherein the wastes are processed into a general purpose matter, application to a wide range of area is permitted, total weight recycling is permitted, emission of substances into the atmosphere is hampered, the degree of curing (gelling) is not changed and the performance of the obtained molded part is stable, and use of this treated product.

In a process for treating coating wastes, an adhesive resin material, preferably a thermosetting resin mold material is applied around a particulate matter obtained by drying, grinding and selecting the coating waste. The treated product of the coating waste is used by introducing the obtained coating particulate matter into a part of a preparation component or a mold and curing it by heat or at a room temperature.
