Waste plastic recycling

 As the consumption of plastic products continues to increase, the amount of waste plastics continues to increase. At present, China's waste plastics are mainly plastic film, plastic wire and woven goods, foam plastics, plastic packaging boxes and containers, daily-use plastic products, plastic bags and agricultural mulch films. In addition, the annual consumption of plastics for automobiles in China has reached 400,000 tons, and the annual consumption of plastics for electronic appliances and home appliances has reached more than 1 million tons. These products have become one of the important sources of waste plastics after being scrapped. It is understood that in 2011, the amount of waste plastics produced in China was about 28 million tons, and in 2012 it was 34.13 million tons. The storage, transportation and processing of these waste plastics, pending the application and post-treatment of the discarded plastic raw materials, will inevitably damage the environment and endanger the health of the people.

To facilitate the recycling of plastics, The Society of the Plastics Industry, Inc., USA proposes a labeling system that uses plastic types to classify: Resin Identification Code. Recyclable plastic containers are accompanied by a triangular label surrounded by three arrows that indicate the type of plastic.

With the large-scale application of plastics, since the beginning of the 21st century, China's plastics recycling industry has become increasingly prosperous, and small and medium-sized enterprises such as Yongquan have emerged with active investment. From the previous family workshop recycling plastics model, the pure business model is driven by market demand. The transformation is developing into an environmentally-friendly industrial economy that is clustered in recycling and processing, intensive in market transactions, and driven by market demand and price.
