Abstract: [Object] To use “fibrous dust” or “particulate dust” which were simple wastes in the past as resources. To improve treatment capacity dramatically.[Solving Means] Non-metal dust which is further pulverized into a small particle size in a pulverizing step S10 through a crushing step Si of crushing wastes such as waste automobiles, waste home appliances, and waste office furniture into a predetermined size, an iron component separation and collection step S3 of separating and collecting an iron component, a non-ferrous component separation and collection step S4 of separating and collecting a non-ferrous component, a metal component separation and collection step S5 of sorting a metal component, wind power sorting steps S2, S6, S8, and S9 of sorting floating “fibrous dust” and a settled crushed material by wind power, and a shredding step S7 of shredding the settled crushed material into a predetermined size is separated into metal scraps such as copper, aluminum, and iron, “fibrous dust”, and “particulate dust” in a separating step S11. “Fibrous dust” and “particulate dust” are separately collected and are used as various fuel resources for household, business, and industry.
