Recycled plastic is the plastic that has the value of recycling after its service life. Almost all thermoplastics have the function of recycling. However, in the process of processing, the loss of molecular weight makes recycled material can not be applied in the field of high performance requirements. To this end, a simple, effective and low-cost method is needed to reduce molecular weight loss and performance degradation. In the near future, the R & D trend of recycled plastics market will continue to develop. At present, renewable resources have become a very important raw material source for our industrial production. The status and role of this industry in the national economy are also gradually highlighted. The recycled plastics industry has become a new trend in the plastics industry. Plastics are easy to process and are rich in plastic materials, so they are widely used and can even replace some wood products, metal products and so on. However, the biggest problem with plastics after they are heavily used is plastic recycling. It's difficult to recycle and burn. It releases harmful gases, which are extremely difficult to break down and cause soil pollution. Recycled plastics can be recycled and used, which belongs to typical environmental protection materials and conforms to the current trend of low carbon and environmental protection. Experts point out that the recycled plastics industry is also a necessary direction for future industrial development, and is an extremely important component of the manufacturing sector. The state also strictly from the policy level to environmental protection, the import and processing of waste plastics are strictly controlled. Since 2012, the Ministry of environmental protection issued the "waste plastic processing and utilization of pollution prevention and control regulations" and "Regulations" of imported waste plastic environmental protection files, improve the processing of waste plastics market access threshold, strictly prohibited waste irresponsible regeneration process, and to standardize the import of waste plastics processing and utilization of enterprise type, and made specific requirements for the processing and utilization of environmental protection enterprises. Talking about the impact of environmental rectification on the recycled plastics industry, the industry pointed out that the environmental rectification for the recycled plastics industry has a serious impact on small workshops and processing enterprises, and has little impact on Enterprises above designated size. Small workshops as part of the lowest end of the industry chain, itself belongs to backward production capacity, does not meet the development needs of the entire industry. In the process of product processing, rough handling is adopted to find only the profit points in the product, and the parts with low profit points or no processing capacity are discarded at will. Two pollution problems are also appearing in this kind of small enterprises, like those in the industrial park is different, generally by the park is responsible for environmental protection, enterprises allocated to pollution control costs reduced, that's better. All along, the plastics industry is the pillar of the national economy, with the usage of plastic products is increasing, the number of plastic products will increase, so the plastic recycling of plastics industry sustainable development is the only way which must be passed. Nowadays, in China, the recycling of plastics has not been fully implemented. However, in the face of the increasingly heavy burden of the environment and the dwindling resources, the recycling of plastic products has become a pressing problem. Xiao Bian believes that if the country actively introduce relevant policies to restrict the masses, with the media for plastic recycling propaganda, and social morality for plastic recycling supervision, I believe that in the near future there will be universal participation in plastic recycling scene.
