Abstract : Plastics are not degradable materials, therefore improper disposal after use constitute environmental problem. The developed plastic recycler was fabricated using 1.5 mm mild metal sheet punched and rolled into cylindrical form. The outer peeling drum was punched inward and fixed to the machine frame while the inner peeling drum was punched outward. The inner drum was constructed using 1.5 mm galvanized metal sheet while the die was constructed using carbon steel. It has an outer diameter of 70 mm and inner diameter of 68 mm. The main frame of the machine was constructed from 50 x 50 mm angle bar to provide support for other units. It has a height of 850 mm, length of 6600 mm and width of 400 mm. A 68 mm diameter and 550 mm length cast iron rod shaft ensures satisfactory rigidity and strength when the shaft transmits power under different operating and loading conditions with the aid of a 3 kW, 3-phase electric motor. The performance valuation of the machine was carried out using polythene bags and polyethylene bottles at speeds 200 and 300 rpm and temperature of 220oC. Results obtained indicated that torque increases for all screw speeds due to a proportional increase in extruder feed rate as screw speed is decreased. The recycling efficiency of the machine is estimated to be 86% while the capacity of the machine is 300 kg/hr. Hence, a cost effective machine for recycling low-density plastic was developed. This will help solve disposal problems of plastics.
