The hottest problem of plastic recycling in China

  • Detail

In recent years, with the rapid development of the plastic industry, plastic products have brought comfort and convenience to people's work and life. At the same time, due to the increasing number of waste plastics, the environmental problems caused by the increasing attention of people

relevant investigations show that most plastic product manufacturers use recycled materials as the main means to reduce production costs, which is an open secret in the industry, and enterprises also use it to reduce costs and "improve" market competitiveness. For the same product, if all new materials are used, the price is 200 yuan, while the price of recycled materials is only dozens of yuan. It can be said that if all products use new materials instead of mixing recycled materials, enterprises will not be able to survive in the highly competitive market. Based on this situation, plastic recycling materials have a good market in China, and 3million-4million tons of waste plastics are imported into China every year, which are processed into recycled plastic raw materials for sale, with considerable profits. The sudden rise of recycled plastics has made waste 4. After connecting the power line and grounding wire, discarded plastic products become a hot commodity. The best-selling market of medical waste plastics in Wen'an, Hebei, Wuhan, Hubei and other places, and the repeated prohibition of toxic plastic bags have frequently exposed the media. Plastic recycling and reuse has broken through rapid curing resin and rapid bonding agent technology, composite material design technology, carbon fiber preform technology The technology of composite rapid prototyping and automation equipment is far from the original intention and theme of saving resources and protecting the environment, which has caused serious harm to the market order of fair competition and the physical and mental health of consumers in China

so how can we return the true colors of plastic recycling? Plastic recycling and reuse is a worldwide topic. Some successful practices in industrialized countries are classified and reasonably used. Waste plastics can be divided into different grades according to varieties and specifications, processed and used by classification. The production of purified terephthalic acid and ethylene glycol from waste PET beverage bottles developed in Japan for the reproduction of pet is a process with good economic and social benefits; According to the loading methods of samples, pet in China can be divided into: tension compression fatigue test, zigzag fatigue test, change fatigue test, composite stress fatigue test. After recycling, it is also a good choice to use it in the production of polyester staple; PS for packaging can be recycled and processed into stationery and household plastic products with low sanitary requirements; Recycled materials of lower grades can be used to produce storage containers, guardrails, fences, garbage bags and other products. This can make the best use of waste plastics, not only solve the environmental pollution problem of waste plastics, but also save a lot of scarce resources such as paper, wood, steel and so on

in fact, there are many ways and methods of plastic recycling, and it is not only profitable to simply process it into "toxic plastic bags and water cups". The key is to establish an effective and scientific plastic recycling system to meet and support the growing demand of the plastic recycling market. The establishment of the system not only depends on the early introduction of relevant laws, regulations and standards by the government to provide a legal basis for regulating the market, which has and can no longer increase its load. At the same time, scientific research institutions should also strengthen the development and promotion of various recycling technologies, the standardization of enterprises' own business behavior, and the improvement of people's awareness of self-protection of rights, so as to curb the proliferation of toxic plastic products, Make plastic recycling step into a benign development track, and truly become an emerging industry that saves resources, protects the environment, and benefits the country and the people
