Before 2017, waste plastics were mainly transferred from developed countries to developing countries, but due to doping restriction and chemical residues, waste residue, waste water and other harmful substances in waste plastics, processing countries need to pay the environmental cost. Since last year, China has issued a ban on waste, since then several countries began to strengthen the control of waste plastics. In addition, the current marine litter on marine life, and water resources caused serious pollution, caused by the attention of countries to increase control.
At present, the control of waste plastics has been extended to the world wide.
First, the waste plastics industry has long been in extensive development, the environment has a multi-pollution China's waste plastics industry originated in the last century in the 80 's, driven by the growing demand, the industry experienced a rapid development cycle. However, the industry has long been in an extensive state of development, subject to the technical backwardness of the industry and the limited cultural level of employees. Domestic waste plastics to small and medium-sized enterprises mainly processing and utilization, but due to the industry supply volume, products, technical backwardness and other practical problems, resulting in low recovery utilization.
In addition, as a policy-oriented industry, policy dredging and guidance have a certain lag and continuity, enterprises run difficult, and restrict the formation of recycling industry chain. Under the extensive development background, the waste plastics industry has caused many pollution to the environment. Single waste plastic sources, there are restrictions such as solid waste, chemical residues, waste residue, waste water and other harmful substances, the ecological environment, water resources, soil and human health will cause a certain harm.
Processing and utilization, will produce waste water, waste gas, pollution of the air, soil, and indirectly threaten people's physical health.
Second, the world-wide control of waste plastics processing industry, the industry has far-reaching impact
Some time ago, Norway suggested that the waste plastics industry should be included in the Basel Convention, and that if the waste plastics were controlled, the import and export trade between the countries would be reduced, but the waste plastics would be processed into recycled plastic granules in the country after import and export transactions. For China, the import of waste plastics has been substantially reduced since the ban was introduced in 2017. 2017 before the annual import volume of 6.008 billion tons, but before September 2018, the total amount of waste plastics audit only 66,700 tons, reduce the range of more than 99%.
At present, China has been increasing the operation mode of the park, strengthening the local recycling, so the short-term will have a certain impact, but the medium and long-term impact on China is small.
Third, the current domestic waste plastics processing industry is facing transformation and upgrading, the main aspects of Which? At present, the import requirements of comprehensive prohibition of waste, the domestic market environmental protection high-pressure form continuation, transformation and upgrading is imperative.
Mode of the main is the park to concentrate on production, or have the strength of the enterprises themselves to handle the EIA and other relevant procedures to go green production mode. For the local recycling industry, the most important thing is to strengthen the source recovery.
At present, domestic waste disposal in the relevant regulations, the need to classify the waste from the source, the use of existing manufacturing capacity, recycling recycled products, including material use and energy utilization.
Iv. what else can the parties do to transform the transition?
Plastic Products Enterprises can implement the producer responsibility system, plastic products after the end of the service life is still recycled by the enterprise, of course, this model is suitable for large-scale electronic appliances and other industries.
Can reduce the amount of plastic at the source, but plastic as a life must be indispensable materials, the annual demand is rising, later may consider the development of plastic-related alternative materials
Domestic to strengthen the source of recovery, and at the source of a good classification, the domestic can form a policy-oriented, based on the recovery site, the establishment of sorting, processing centers, clustered sorting centers and processing centers for the node, the formation of waste plastic recycling network and industrial chain.
Waste plastics enterprises to use color sorting machine, the color separation machine will be separated, can increase the utilization of waste plastics Water-free cleaning can improve product quality and material yield. The energy required for extrusion is reduced due to the drying of the clean material after recovery.
