1. People pay more and more attention to the treatment of waste plastics
Plastics are considered one of the greatest inventions of the 20th century, which greatly facilitates people's production and life. However, a large amount of waste plastics are piled up in landfills or discarded into the environment, posing a serious threat to the natural ecosystem. Traditional treatment methods cannot change the status quo of resource waste and environmental pollution. Therefore, exploring environmentally friendly and economical ways to recycle plastic waste and realizing the transformation of plastic consumption from a disposable economy to a circular carbon economy have become hot spots and problems in the field of plastic recycling.
