Introduction of HDPE and PP recycling at home and abroad

The recycling of HDPE and PP abroad: mainly introduces the work done by APR (USA) and PRE (Europe) in HDPE and PP recyclability design. Unlike PET, HDPE has many grades and a wide range of applications, which brings certain challenges to recycling. Foreign recycled HDPE is mainly used in pipelines. There is no requirement for appearance, but the quality requirements are very high. Another application area is bottles. The main challenge is color. The color of variegated recycled materials limits its application areas. The recycling rate of PP in North America is not high, because the United States believes that PP recycling has not reached the scale (less than 60%).

Domestic HDPE and PP recycling situation: Domestic HDPE and PP waste sources are mainly domestic and industrial sources. The source of life is through individual picking and collection, through the waste recycling station, manual sorting to the packing station. Garbage classification is mainly based on the "point-station-yard" model, which is still a pilot.
