(1) PCR plastic is one of the important directions to reduce plastic pollution and help “carbon neutrality” Since the invention of plastic, plastic products have brought great convenience to human living standards, and it has been difficult for human beings to leave plastic products. However, the waste problem brought by plastic products has become one of the development dilemmas of human beings. About 30 million tons of plastic waste are produced every year, of which 14.1 million tons are plastic packaging waste, and only a small portion of plastic waste is properly treated. Source: “Single-use plastics a roadmap for sustainability”), which shows that plastic recycling is still at a relatively low level. Then PCR plastics are mixed with virgin plastics and reused to make plastic products. This approach not only reduces CO2 emissions, but also reduces energy consumption and helps protect the environment. (2) Use of PCR plastics to further promote recycling of waste plastics The more people who use PCR plastics, the greater the demand will be, which will further enhance the recycling of waste plastics and will gradually change the model and business operation of waste plastics recycling, meaning less waste plastics going to landfills, incineration and existing in the natural environment. (3) Promotion of Polices Many countries around the world are now legislating the mandatory use of PCR plastics.
