The invention relates to a disposing and utilizing method for decoration waste and/or room demolishing waste. The disposing and utilizing method includes the following steps that firstly, the decoration waste and/or the room demolishing waste are/is subjected to breaking and screening pretreatment; secondly, noncombustible goods separated after pretreatment in the first step are conveyed to a gravity separator on the basis of dry method disposing, dust is suppressed through dry fog, and after gravity separation, the noncombustible goods are separated into heavy materials, medium materials, light materials and powder according to the specific gravity of the materials; and thirdly, the second step is cycled, the heavy materials, the medium materials, the light materials and the powder obtained after disposing are used as industrial raw materials according to needs. After above pretreatment and gravity separation, the absorption directions and utilization corresponding to all the classified materials are obtaine
