The United States is the world's largest producer of plastics. According to statistics, by the year 2000, the United States produced more than 34 million tons of plastics and more than 16 million tons of used plastics.

As early as the 1960s, the United States began extensive research on the recycling of waste plastics. However, if the pace of recycling waste plastics is not accelerated, it will not be able to withstand the environmental pollution caused by the growing waste plastics and the economic losses. The proportion of recycled plastics in the United States is 50% for packaging products, 18% for building materials, 11% for consumer goods, 5% for auto parts, 3% for electrical and electronic products, and the proportion of plastics is 61% for polyolefins. %, polyvinyl chloride accounts for 13%, polystyrene accounts for 10%, polyesters account for 11%, and others account for 5%.

In the late 1980s, the recycling rate of waste plastics in the United States was nearly 10%. According to statistics, the recycling rate of waste plastics in the United States at the end of the 20th century reached more than 35%. Among them, the recycling energy of burning waste plastics increased from 3% in the 1980s to 18%; the buried rate of waste products dropped from 96% to 37%. The United States has done a lot of work in the combustion of [url]waste plastics[/url]http://www.recycle-plant.com/pp-pe-flake-products-recycling-and-pelletizing-machine using thermal energy, thermal decomposition and extraction of chemical raw materials, and has achieved some results. In addition, the US states have adopted tough measures such as legislation to solve the problem of plastic waste.
