Optimizing the Recycling Process of PP Plastics from Waste Washing Machines: Sustainable Strategy for Environmentally Friendly Reutilization

ACS Sustainable Resource Management, Год журнала: 2024, Номер 1(6), С. 1247 - 1255

Опубликована: Май 23, 2024

The resource utilization of waste plastics is an inevitable trend toward achieving sustainable social development. plastic in washing machines a highly potential source recycling. This study developed strategy for effectively regenerating PP from machines. optimal process parameters friction alkali were determined through response surface curve analysis. Under the conditions 280 rpm, 10 min, and pH = 12, proportion black spots impurities decreased to lowest amount 11.69 × 10–3 wt %. Additionally, physical sorting, granulation, regeneration was constructed. Large-scale data statistical analysis indicated that recycled exhibited excellent stability performance impurity content. Meanwhile, different formulations designed modify improve properties PP. achieved provides theoretical practical guidance environmentally friendly reutilization plastics.

The regeneration of plastic components from waste refrigerators is an inevitable trend for sustainable social development. However, the technical process and practical verification industrial recycling plastics are missing undisclosed. In this study, a detailed physical sorting route purification ABS PS in was revealed. residual glass content recycled flakes 0.013 0.019 wt %, metal 0.17 0.21 respectively. Based on large-scale statistical analysis real production line data, feasibility reliability study were verified. average impact values white gray 11.7 12.05 kg/m2, 7.52 7.56 kg/m2. Through bromine typical heavy elements, proven to meet commercial standard requirements RoHS 2.0. Meanwhile, based material flow analysis, suggestions guidance proposed. summary, provides effective inspiration refrigerator plastics.
