Abstract (en)

[origin: CA2095979A1] SYSTEM AND METHOD FOR RECYCLING MATERIALS First and second washing machines (13, 15) are utilized to clean plastic (87) and cellulose (53) from disposed diapers (49) for recycling. The disposed diapers (49) are loaded into the first washing machine (13) and, while being agitated by rotation of a basket (37) and by air supplied by a blower (23), are washed in water, alkali and soap. During washing, the cellulose becomes separated from the plastic. The cellulose is drained out of the first washing machine with the water, leaving the plastic in the first washing machine. The plastic is then cleaned in the first washing machine. A pump (17) transfers the cellulose and water to the second washing machine (15). In the second washing machine, the cellulose is washed in alkali and soap while being agitated. The second washing machine has a screen (48) for retaining the cellulose therein, while passing the water and waste material. Wood pulp goods, rubber, glass and plastic are other materials that can be processed and cleaned for recycling purposes.
