Method for disposal of refuse and recovery of by-products
Abstract
Abstract REFUSE IS IMMERSED AND AGITATED IN WATER IN A TANK TO SEGREGATE COMPONENTS BY SPECIFIC GRAVITY. LIGHT AND HEAVY COMPONENTS ARE SEPARATELY REMOVED FROM THE TANK AND SEPARATELY PROCESSED. MEDIUM WEIGHT COMPONENTS ARE PRIMARILY PAPER AND FIBER PULP STOCK. SUCH STOCK IS PURIFIED, THEN PROCESSED INTO PULP BOARD IN A MILL. WATER DRAINED FROM THE MILL IS FILTERED AND RECYCLED. COMBUSTIBLE REFUSE IS USED AS FUEL TO BURN CONTAMINATED REFUSE AND TO PRODUCE STEAM FROM SOME OF THE WATER. THE STEAM IS USED TO CLEAN CERTAIN COMPONENTS, TO PURIFY PULP STOCK, AND TO FORM "POTABLE" WATER BY CONDENSATION. SLUDGE SETTLING FROM THE TANK, THE FILTER AND THE BURNER IS USED FOR FERTILIZER. MANY OTHER USEFUL BY-PRODUCTS ARE RECOVERED.
