<p>PROBLEM TO BE SOLVED: To provide an optimum way of treatment of waste plastics to recycle as a resource in compliance with the quality of the waste plastics such as contamination or degradation and with the demand of the recycled product. SOLUTION: This recycling equipment comprises an extrusion device 1 to extrude a waste plastics by heating and melting, a distributing pipe 2 to transfer the molten plastics extruded by the extrusion device 1, and a cracking device 3 and a pelletizing device 5 each connected to the pipe 2 via valves 4 and 6. Upon recycling, the ratio of recycling by the pelletizing device 5 and by the cracking device is adjusted in compliance with the quality of the waste plastics and the demand of the recycled product.</p> |
