Since plastic itself cannot degrade under natural conditions, the accumulation of waste plastic can also cause "white pollution". At the same time, waste plastics still contain huge renewable resources, and the existence of "white pollution" is a huge waste of limited earth resources. Therefore, recycling of waste plastics is not only the key to sustainable development of the plastics industry in this century, but also an important measure to solve environmental pollution, and environmental protection departments and manufacturers have joined this research.

Therefore, the recycling of waste plastics is not only the key to the sustainable development of the plastics industry in this century, but also an important measure to solve environmental pollution. "White pollution" has attracted widespread attention from citizens, governments, manufacturers and academia, and great progress has been made. In China, waste plastics recycling technology started late, but is progressing rapidly. Many universities, chemical institutes, environmental departments and manufacturers have joined this research.
Waste plastic recycling technology is the direct processing and molding of recycled plastic products by identifying, sorting, cleaning, shredding or dissolving, melting, or by mechanical mixing or chemical modification, followed by processing and molding. Recycled plastics are different forms of plastics that still have recycling value at the end of their useful life. Almost all thermoplastics have recycled value. Recycled plastics will be produced according to these processes, such as synthetic resin production processes, production and processing of plastic products and semi-finished products, plastic logistics processes, and post-consumer use. For example, synthetic and processed factory waste plastics are referred to as pre-consumer plastics; some materials, such as supermarket shopping bags, food packaging, beverage bottles and other waste plastics, are produced after distribution, consumption and use and are referred to as post-consumer plastics. Pre-consumer produced plastics are small in size, consistent in quality and have a high recycling value. They are properly handled during the manufacturing process and can be fully reused. When we refer to recycled plastics, we are usually referring to recyclable plastic products that have lost their use value after consumption and can be recycled. Plastics can be recycled, concentrated, sorted, and scientifically and rationally processed for recovery value and recycling.
Plastics are recovered, concentrated, sorted and scientifically and rationally processed to obtain recovery value and achieve recycling.
