In recent years, the harm of plastic products to the environment is more and more serious. It is reported that China's annual plastic waste is more than 3 million tons, and China consumes 15 billion disposable lunch boxes every year. Plastic products in the world increase at the rate of 9% every year. Most of them are difficult to degrade. If discarded at will, it will cause lasting pollution to the environment. According to figures released by the world observation Institute, less than 10% of the world's plastic products are recycled every year. Waste plastic products contain monomer ethylene and volatile toxic substances such as ethylene, cumene, toluene, etc., which cause long-term deep-seated environmental problems due to the difficulty of degradation after entering the environment, forming "white pollution".
