According to the data provided by the Department of Resources Conservation and Comprehensive Utilization of the former State Economic and Trade Commission, during the â€œNinth Five-Year Planâ€ period, Chinaâ€™s cumulative use of over 10 million tons of waste plastics was recycled. About 14 million tons of waste plastics are not recycled every year. Only 25%. The State Economic and Trade Commission clearly stated in the â€œTenth Five-Year Plan for the Recycling of Renewable Resourcesâ€ that by 2005, Chinaâ€™s annual recycling of waste plastics will reach 5 to 6 million tons.
Plastics have excellent chemical stability, corrosion resistance, electrical insulation, thermal insulation, excellent shock absorption and noise reduction, and good elasticity, and can be well bonded with other materials such as metal, glass, wood, etc. , easy processing and forming. Among the four major industrial materials, the number, role, and scope of applications of plastics have expanded dramatically, leading to steadily increasing numbers, replacing metal, wood, and paper, and are widely used in various fields of the national economy. At the end of the 1960s, ferrous metals accounted for 60% of the total consumption of structural materials; in the 1990s, synthetic plastics accounted for 78% and ferrous metals accounted for 19%. It can be said that no material has such a wide range of uses as plastics. Therefore, scientists have declared that "Mankind has entered the age of polymer synthesis materials!".
However, it is precisely due to certain excellent properties of plastic that it will not be able to rot after use or consumption, and it will affect the ecological environment of the earth. It has aroused great concern in the world. In 1997, the worldâ€™s total plastic output exceeded 14,000 tons, its volume was equivalent to 1 billion tons of steel; in 1995, Chinaâ€™s plastic products industry sales reached 110 billion yuan; in 2000, Chinaâ€™s annual output of plastic products has exceeded 12 million. Tons, and with a 13% annual growth rate, the total amount of waste plastics will also grow sharply, and the contradiction between environment and development will become increasingly prominent. Therefore, the management of waste plastics has become an urgent matter.
According to statistics from relevant departments, the plastic waste generated in a medium-sized city can satisfy the raw material needs of 20 small and medium-sized plastics enterprises. The waste plastic resources are called by modern economists as "human second-mineral deposits" and "in cities." "The treasures"! Development and utilization of waste plastic resources can effectively control pollution and create huge economic and environmental benefits. It is a green environmental protection industry that benefits the country and the people.
Waste plastics have enormous wealth and unlimited business opportunities. Therefore, when China and the United States negotiated about Chinaâ€™s accession to the WTO, the United States proposed the reciprocal conditionâ€”that is, it requires China to open the environmental protection market to the United States, which includes the recycling of waste plastics. Japan's export of waste plastics to China in 2002 increased by 40% year-on-year to approximately 549,000 tons, an increase of approximately 8.1 times in 10 years. At present, Japan's domestic waste raw material collection operators concentrate on exporting to China after stocking. In recent years, China has become the largest importer of waste plastics in the United States, Japan, and South Korea.
Waste plastics distribution and sources
As long as there are people, there will be plastic waste. All kinds of plastic packaging, shopping bags, agricultural film, woven bags, beverage bottles, plastic pots, plastic pots, plastic buckets, toys, stationery, plastic shoes, vehicle bumpers, household appliances shells, computer shells, waste polychlorinated pipe, Industrial waste plastic products, plastic doors and windows, polyester products (polyester film, mineral water bottles, coke bottles, etc.) and waste materials in the plastic molding process, etc., are everywhere, endless, and never exhausted.
Since the 1950s, China has begun to establish a unique waste recycling system. At present, there are more than 5,000 kinds of waste material recycling enterprises in the country, with 160,000 recycling outlets, and it covers almost every township, town, and large, medium, and small cities. There are a large number of waste plastics of all types, suitable for batch production. buy. Corresponding to this is that there is an extremely large number of waste materials purchased by the army in various parts of the country, and they will purchase the waste plastics in their hands, which will reduce the procurement costs of raw materials. According to reports, about 9% of the 1.32 million tons of garbage produced in Changchun each year are waste plastics. Only this one, Changchun is buried every year worth more than 10 million yuan of wealth.
The leftovers produced during the production and processing of plastic products factories are not classified and cleaned, and are good raw materials for processing and recycling of particles. Establish business contacts with the plastics factory, process the purchased scraps into pellets and return them to the plastics factory, or charge a certain processing fee. In this way, it not only solves the recycling problem for the plastic factory, but also is an effective way to generate income. It is a win-win solution.
The mulch used extensively in the rural areas of northeast, northwest, and north China is a one-time use of agricultural materials, and is huge in quantity and low in price. The vast numbers of rural people are adequate. If the organization staff collects or purchases on their own, they can not only solve the problem of soil pollution caused by the plastic film, but also eliminate intermediate links. While ensuring the source of raw materials, they can also significantly reduce the cost of raw materials and increase profits. .
In summary, low-cost, readily available waste plastics are everywhere, providing unique conditions for us to set up a recycling plant for waste plastics. Realize the acquisition, processing and sales of used plastic on the spot, with favorable conditions and advantages.
