PURPOSE:To select surely and efficiently each recyclable item by a simple procedure by a method wherein magnetic metals are extracted from a refuse and aluminums are extracted from the refuse after extraction and round objects are extracted from the refuse after extraction and the extracted round objects are selected into bottles and lightweight resin bottles. CONSTITUTION:From a collected refuse wherein recyclable items are mixed, long and large items such as carpets and blinds are at first selected and removed in a long and large items-selecting process 1. Next, bags and refuses being come out from bags and loose in bulk are selected in a bags-selecting process 2 and the bags are broken to take out refuses in the bags in the bag- breaking process 3. Then, the procedure is shifted to a magnetic items-selecting process 4, where magnetic metals such as iron are selected. Thereafter, aluminums such as aluminum cans are selected in an aluminum-selecting process 5 and the procedure is shifted to a round items-selecting process 6, where round items such as bottles, PET bottles and other lightweight resin bottles are selected. Finally, in a lightweight items-selecting process 7, the bottles and the lightweight resin bottles among round items are selected. |
