Relevant experts pointed out that because waste plastics are rich in resources and cheap to recycle, they are supported by the state (tax-free), with less equipment investment and simple production process, so there is a big way to recycle waste plastics in China

at present, there are nine ways to comprehensively utilize waste plastics at home and abroad:

1? Make fuel? In recent years, a new practical technology -- waste plastic recycling fuel technology and process equipment has been successful in Chengdu? This waste plastic recycling factory uses waste plastics, such as food bags? Waste woven bags? Drink bottle? Plastic sole? Wire and cable sheath? Foam lunch box? Plastic toys and other products produce high-quality 90# fuel oil, which is qualified by the Sichuan Provincial Bureau of technical supervision. The company's strength is to use this kind of fuel oil, and one ton of waste plastic can produce about half a ton of oil

according to experts, there is no technical problem in cracking waste plastics into fuel, but in actual production, including Europe? Beauty? Japan and others have not been reported and documented? In China, this research can be done in the laboratory, but in practice, due to the high production cost P) overload protection: when the load exceeds 3 5% of the maximum value of each gear, it is difficult to produce economic benefits, so it is impossible to carry out large-scale production? Therefore, the technological achievement born in Chengdu provides an effective way for China to control white pollution? Feasible new technology

2? Produce waterproof and antifreeze glue? With foamed plastic waste as the base material, produce multiple varieties under special formula and process conditions? Multi purpose indoor and outdoor building decoration water-resistant glue paste glue liquid series products, is it a small investment? Quick effect? Competitive? Energy efficiency is an ideal project to eliminate plastic pollution? Each ton of waste can produce several tons of finished rubber. Based on the minimum package of 5kg and 200 barrels per ton of rubber, the comprehensive production cost is about 3000 yuan, and the selling price is about 6000 yuan

3? Making aromatic compounds? Japan is carrying out practical research and development of new technology for preparing chemical raw materials from waste plastics? The method is to put PE? When PP and other waste plastics are heated to 300 ℃, they are decomposed into carbohydrates, and then catalysts are added to synthesize benzene? Aromatic compounds such as toluene and xylene? When reacting at 525 ℃, 70% of waste plastics can be converted into useful aromatic substances, which can be used as raw materials for chemicals and pharmaceuticals and fuel improvers for gasoline? The rest can be converted to hydrogen and propane

4? Preparation of multifunctional resin adhesive? Does the product have good adhesion? High gloss? Strong impact resistance? Acid and alkali resistance, daily output of 1 ton, cost of 2300 yuan per ton, market price of 5000 yuan? In industry, it is used to produce all kinds of FRP products, which can greatly reduce the production cost. In addition, it can also make waterproof coatings? anticorrosive paint? Furniture putty glue and other products can replace all kinds of glass glue? Wood glue? Use of printing adhesive

5? Aluminum plastic automatic separator? Aluminum plastic composite packaging is widely used in food? Pharmaceutical packaging? With the progress of society, waste is increasing year by year. Due to the combination of aluminum and plastic, it cannot be granulated, and no one cares about recycling. It can only be incinerated, which not only pollutes the environment but also wastes resources? Using aluminum-plastic automatic separating agent, put the waste aluminum-plastic package into the container, add water and automatic separating agent, and the aluminum-plastic package will completely separate the aluminum-plastic in about 20 minutes. 0.85 tons of recycled plastic and 0.1 tons of waste aluminum can be separated from each ton of waste aluminum-plastic package? One ton of waste aluminum plastic composites is recycled every day, and the profit is yuan

6? Fireproof decorative board? Widely used in interior decoration? suspended ceiling? Furniture manufacturing? This product is not only colorful in appearance, but also fireproof? Waterproof? anticorrosive? Insulation? Invariant? Not aging? Can be curled at will

7? Regenerated particles? Using special granulation equipment, waste polyethylene can be recycled? Polypropylene and other plastics are processed and produced into marketable recycled particles through the process of crushing, cleaning, heating, plasticization and extrusion? Can you make a profit of yuan per ton per day

8? Producing king of leaks? It is an upgraded product of traditional waterproof materials. When used on the surface of a house, it is like brushing a layer of sodium glass. Is it fast to close? Highly permeable, with rapid drying? Plasticizing fast? Good leveling performance and strong adhesion? Acid and alkali resistance, with a service life of more than 20 years? Moreover, the construction is convenient. It can be constructed all year round without heating. It can be coated immediately? Low cost, high profit, cost yuan per ton, market price of 5000 yuan

9? Produce plastic woven bags? Sangcai Town, Shanting District, Zaozhuang City, Shandong Province uses waste white plastic products to process? The production of plastic woven bags not only solves the problem of environmental pollution and measures go data, but also increases farmers' income? At present, 201 plastic granule processing plants and 23 plastic woven bag factories have been established in the town, with a daily output of 500million woven bags, forming the acquisition of waste plastics? Transportation? Processing and printing go hand in hand, with an annual sales volume of 350million yuan, absorb more than 6000 rural labor forces, and become the branch of farmers in the town to get rich. This kind of process combines the design flexibility of injection molding and the strength and stiffness of unidirectional thermoplastic composites
