With the development of the economic situation and the advancement of science and technology, each market faces different opportunities and challenges. As a polymer compound polymerized by polyaddition or polycondensation, plastic is favored by consumers and merchants because of its various excellent properties and low manufacturing cost. However, due to the inability of plastics to degrade naturally, most of the plastics are discarded after they are used. The problem of white pollution has become a difficult problem that humans have tried for a long time. So far, the academic community believes that ordinary plastic products will not be decomposed due to their stable physical and chemical structure and may be tens to hundreds of years in the natural environment.
Faced with more and more serious environmental pollution, human environmental awareness has gradually deepened, and many places have begun to introduce “plastic limit orders”. People themselves have begun to actively reduce the use of plastic products, which is undoubtedly facing a severe industry for the plastics industry. The test of transformation, coupled with the state's strict control over the import of “foreign garbage” and the adjustment of relevant policies, demonstrate the firm determination of the country to follow the path of sustainable development.
Recycled plastic, broad prospects
In the context of increasingly strict environmental protection, the recycled plastics industry, as a member of plastics, has caught people's attention. The reuse and reprocessing of plastics is undoubtedly an interpretation of the word "environmental protection". The waste plastics are re-formed into plastic raw materials by mechanical blade pulverization, pretreatment, melt granulation, modification, etc., on the one hand, the utilization of limited resources is greatly improved, and on the other hand, the pollution of plastics to the environment is reduced. In addition, the source of waste plastics is wide, the price is low, the price of recycled plastics is high, and the sales are good. The rational application of recycled plastics makes the utilization of resources increase sharply, which can effectively reduce the loss of resources.
Affected by import policies, domestic demand and crude oil prices, large-scale waste plastics recycling enterprises have accelerated their development in recent years. Technology upgrades have promoted the improvement of recycled plastics quality, and industry competition has gradually penetrated into the mid- to high-end areas. It has emerged, which in turn has led to the continuous improvement of the domestic waste plastics recycling system.
Policy support, promote regeneration
The Industrial Green Development Plan (2016-2020) requires that by 2020, the recycling of domestic waste plastics should reach 23 million tons. It is necessary to speed up the efficient use of renewable resources and the development of industrial norms, and accelerate the promotion and application of advanced and applicable recycling technologies and equipment around major renewable resources such as waste plastics. Construct a batch of renewable resource industry clusters, promote the coordinated use of renewable resources across regions, build a regional recycling resource recycling system, and promote the gradual standardization of the industry order.
In May 2017, the National Development and Reform Commission issued the “Circular Development Leading Action”, proposing that by 2020, the recycling rate of major wastes should reach about 54.6%; it is necessary to promote the recycling of industrial waste, promote the recycling of renewable resources, upgrade and support, and then support The production industry is standardized and scaled up, and a regional resource recycling system is constructed. In addition, the producer responsibility extension system was introduced to establish a system for the promotion and use of recycled products and recycled raw materials.
Subdividing plastics to prevent pollution
At present, it is particularly important to carry out classified collection and recycling of waste plastics. In order to increase the value of recycling and utilization of waste plastics and prevent environmental pollution, some environmentalists in China are also actively contributing to the promotion of “turning waste into treasure” to prevent pollution. For example, on the basis of the garbage classification that is currently being implemented, the plastic waste is finely classified and recovered from the source according to the variety. For waste plastics that cannot be sorted and recycled at the source, they are encouraged to be used as raw materials for building materials after recycling, or for making low-grade plastic products; plastics mixed with organic waste, etc., are burned after water removal, and their calorific value is recovered. At the same time, Hu strengthens the publicity and education on the recycling of waste plastics value preservation, requiring units and individuals to carry out preliminary cleaning before discarding plastics, and preliminary classification according to materials, which is convenient for recycling and value preservation.
The industry believes that pollution prevention is a three-dimensional battle. It is necessary to enter the underground river into the sea. At the same time, it is necessary to focus on fulfilling environmental responsibility for enterprises and establish and improve a set of scientific and feasible emission reduction mechanisms and standards. This also gives corresponding instructions and requirements for the environmental protection of enterprises. In the process of reducing emissions and anti-pollution, the recycled plastics industry will also play a certain role in the treatment of waste plastics, while improving the availability of resources and reducing The extent of plastic contamination.
The industry proposes to carry out classified collection and waste value utilization of waste plastics, and “turn waste into treasure” to prevent pollution. In order to increase the value of waste plastic recycling and prevent environmental pollution, on the basis of the waste classification that is currently being implemented, the plastic waste is finely classified and recovered from the source according to the variety. For waste plastics that cannot be sorted and recycled at the source, Hu Wei recommends encouraging recycling as a raw material for building materials, or for making low-grade plastic products; mixed plastics such as organic waste, which are incinerated after water removal and recover their calorific value. At the same time, Hu Wei proposed to strengthen the publicity and education on the recycling of waste plastics value preservation, requiring units and individuals to carry out preliminary cleaning before discarding plastics, and preliminary classification according to materials to facilitate recycling and value preservation.
summary
Increasing the utilization rate of resources has become one of the important environmental protection goals under the current social situation, and recycled plastics have entered the plastics industry as a social undertaking that promotes economic development and protects the ecological environment. Although China's recycling system is still in its infancy, in the long run, recycled plastics with green energy-saving characteristics are bound to become an important part of promoting the development of environmental protection and one of the ways to implement the concept of sustainable development.
Affected by environmental protection and supply-side reforms, the recycling of recycled plastics has declined in the past two years, and some waste plastic recycling sites have been suspended. Despite this, recycled plastics is still a green development industry encouraged by the current national policy, and it is responsible for solving the problem of reducing and recycling a large amount of waste plastic solid waste for the whole society. In the near future, the recycled plastics market will eventually form a waste plastics recycling processing and utilization network system and industrial chain, and the recycling of plastics industrial parks, industrialization and scale construction will be an inevitable trend in the development of the entire industry.
In short, for the maintenance of environmental protection, everyone should keep in mind, not only for the current development of the earth, but also for the future of the global environment to add a touch of tranquility and peace, no one hopes, many years later, gave birth to The earth mother of hundreds of millions of people has become old and ruined.
