China is the second largest plastic product country in the world, and the plastics industry is an important industry for the national economy. Raw materials for plastics mainly come from non-renewable fossil fuels such as petroleum, coal and natural gas. The consumption of petroleum resources in China is very large, and the situation in which plastic materials are heavily dependent on imports has not been fundamentally changed. The recycling and recycling of waste plastics is a major strategic issue for the country to resolve resource shortages. The rich source of recycled plastics and its low cost are short-cuts for solving the shortage of raw materials, and it is an environmental protection industry that benefits the country and the people. It has become an important part of the sustainable development of the plastics industry. After rapid development in recent years, it has shown good development. momentum:
First, more and more plastics manufacturers and modified plastics manufacturers are making heavy use of recycled plastics. The recycling and recycling industry of China's waste plastics has shown rapid development, and the status and role of recycled plastics in the raw material market has become increasingly prominent. Secondly, regional distribution centers for processing transactions have developed toward clusters. The Yangtze River Delta, the Pearl River Delta, and the three major waste plastic recycling areas centered on Hebei have formed a market-oriented and environmentally friendly industrial economy driven by market demand and price. Third, China's global waste plastic procurement system has gradually taken shape. According to customs statistics, in the past five years, the average annual growth rate of China's imports of waste plastics has reached 24.4%, which is far higher than the growth rate of imports of new materials. Last year, the import of waste plastics reached 5.865 million tons, which is the world's largest import volume of waste plastics. Fourth, the waste plastics recycling and recycling industry has made continuous progress in the application direction and key technologies. At present, it has been able to develop polyethylene, polypropylene waste film recycling production equipment, plastic crusher, recycling granulator, pelletizing equipment, etc. The domestic market has formed a certain degree of competitiveness.
However, due to the disordered and low-level processing of China's waste plastics recycling and recycling industry, the “double-edged sword†effect on the environment has emerged in the recycling-recycling transition, that is, the pollution of the environmental protection industry is severe, which restricts the healthy and sustainable development of the industry. . There are three reasons for the secondary pollution of waste plastic recycling:
First, the barriers to entry are low, and some small companies ignore environmental protection driven by interests. They do not process in accordance with environmental protection requirements. They deal with waste plastics with low-cost equipment and cheap labor. They even use industrial alkaline water to clean plastics. Wastewater does not circulate. With or without treatment discharge, waste residue is piled and discarded without treatment. The waste of resources and secondary pollution caused by traditional extensive operations are serious. On the one hand, resources are reclaimed on the one hand and the environment is polluted on the other.
Second, in recent years, China has attached great importance to the development of recycling economy, and has done a lot of work in terms of policies, funds, etc. However, the status quo of the entire weak foundation of waste recycling industry has not been fundamentally changed, and the development of renewable resource recycling technology has been heavily invested. Insufficiency, policy support is not in place, and a reasonable and complete environment-friendly recycling and reuse system has not yet been formed.
Thirdly, China's imported waste materials management system still has flaws, and there are legal gaps in waste utilization, dismantling, etc. Some bad companies in some countries use evasive measures to dump “foreign waste†to China in the name of waste plastics, while in China It seems to the importer that as long as there is a huge profit, the import of waste is also not hesitate, this action not only seriously polluted the domestic environment, but also impacted the processing and application industries of waste plastics, and cast a blind eye on the industries that benefit the country and the people. shadow.
In order to make the waste plastic recycling and recycling industry develop healthily along an environmentally friendly track, the author suggests:
First, we should improve the laws, regulations, and standards for the development of circular economy and resource conservation, establish and promote resource conservation management mechanisms that are in line with China's national conditions, implement price and fiscal policies that are conducive to resource conservation, and extensively carry out resource-saving publicity and education activities.
Secondly, the government should further improve the environmental protection standards and classification technology standards for the recycling and utilization of waste plastics, implement the plastic recycling mark and national standards, strengthen the management of plastic recycling technologies, accelerate the innovation of processing and utilization methods and environmental protection technology, and promote industrial upgrading.
Third, strengthen the supervision of imported plastics, and resolutely resist the import of plastic waste, and through the introduction of relevant laws and regulations, market access conditions and other ways to promote the plastic recycling industry trade classification system.
Fourth, to strengthen the management of the domestic plastic recycling processing industry, gradually cancel the workshop-style factories, achieve intensive, large-scale, and park-based operations in the entire industry, fail to achieve environmental protection standards, and cannot process and utilize renewable resources in an environmentally friendly manner. Prohibit its production, change the situation of the past scattered, chaotic, and poor, to achieve the purpose of comprehensive management.
