The raw materials for recycled PET mainly refer to discarded PET bottles in various forms and waste generated during the production of a small amount of PET. The physical recycling of PET bottles is relatively simple, mainly the drying and granulation of the washed PET bottles. The physical treatment method of PET plastic bottles is closely related to the sorting process. There are two kinds of physical recycling methods. First, the waste PET bottles are shredded into pieces, and HDPE, aluminum, paper and adhesives are separated from PET. The PET chips are then washed, dried and pelletized; secondly, non-PET caps, bottoms, labels and other impurities on waste PET plastic bottles are mechanically separated, washed, broken, and granulated. Social development and people’s daily consumption have increased concerns about environmental impact, and China’s strong demand for resource demand has led to increasing demand for foreign recycled PET raw materials in China. However, after China introduced a 'ban on order' in 2017, a lot of ' Foreign garbage was rejected outside the country, and the amount of recycled PET imports was also quietly changing.
In February 2018, the amount of recycled PET imports was 0.015 million tons, which was a decrease of 93.78% from the previous month; it was down 99.94% year-on-year (246,700 tons), which was a significant drop. This was mainly due to the domestic customs’ Conducting comprehensive inspections has made imported products subject to greater limitations. In addition, during the Spring Festival holiday in February, imports have fallen significantly. Affected by the domestic ban on the use of waste, large quantities of raw materials for recycled plastic products have been restricted, and imported pellets have been re- In the future, the market will occupy a large share. Domestic chemical fiber plant of renewable PET currently has high in-store inventory, coupled with weak fluctuations in prices of upstream PTA and MEG products, bottle-grade and fiber-grade PET prices are low, forcing prices of recycled PET products to fall more than once, In the short term, the recovery trend is not strong. However, the amount of recycled PET imported in the later period is not much changed compared to January-February, and the low import volume has become a trend in the latter period.
