Waste plastic recycling

Relevant experts pointed out that due to the abundance of waste plastics in China and the low cost of recycling, it is a national support project (tax exemption), and the investment in equipment is small, and the production process is simple. Therefore, there is a lot of “money” for the recycling of waste plastics in China.

At present, there are 9 main ways for the comprehensive utilization of waste plastics at home and abroad:

1?Manufacturing 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 plastic , such as food bag waste bag, beverage bottle and plastic. sole? wire and cable Paper? foam lunch boxes? plastic toys, production of high-quality fuel # 90, Sichuan Province and Technical Supervision inspection qualified lead-free high-quality fuel, the company's strength is the use of this fuel, while one ton of waste plastic can About half a ton of oil produced?

According to experts, there is no technical problem in cracking and processing waste plastics into fuel. However, actual production, including Europe, America, Japan, etc., have not been reported or documented. In China, this research can be conducted in the laboratory. In fact, because the production cost is too high and it is difficult to produce economic benefits in practice, large-scale production cannot be carried out. Therefore, the technical achievements born in Chengdu provide an effective and feasible solution to the “white pollution” in China. new technology?

2?Production of waterproof and anti-freeze rubber? With foamed plastic waste as base material, in a special formula and process conditions to produce many varieties? Multi-purpose indoor and outdoor architectural decoration water-resistant adhesive paste glue series products, is a small investment? Fast? Competitive? Energy efficiency The ideal project to eliminate plastic pollution? Each ton of waste can produce several tons of finished rubber, according to the minimum package of 5kg x 200 barrels per ton of plastic. The total production cost is about 3,000 yuan, and the selling price is around 6,000 yuan.

3. Preparation of Aromatic Compounds Japan is currently working on the development of a new technology for the production of chemical raw materials from waste plastics . The method is to heat PE plastics such as PP to 300 °C to decompose them into carbohydrates. After adding a catalyst, aromatic compounds such as benzene, toluene and xylene can be synthesized. When reacted at a temperature of 525°C, 70% of used plastics can be converted into useful aromatic substances. These substances can be used as chemicals and pharmaceuticals. The raw materials and gasoline fuel improver, etc., are widely used? The remaining components can be converted to hydrogen and propane?

4? Preparation of multi-functional resin glue? This product has good adhesion, high gloss, strong impact resistance, acid and alkali resistance, etc., 1 ton per day, 2300 yuan per ton cost, market price of 5,000 yuan? Industrial The production of various glass steel products can greatly reduce the production costs, in addition, can also be made of waterproof paint, anti-rust paint, furniture putty glue and Other Products, can replace a variety of glass glue, wood glue, printing glue used?

5?Automatic aluminum-plastic separating agent? Aluminum-plastic composite packaging is widely used in food and pharmaceutical packaging . With the progress of society, waste increases year by year. Because aluminum-plastic composite together, can not be granulated, recycling is no one cares, can only be carried out Incineration, which not only pollutes the environment but also wastes resources. It adopts aluminum-plastic automatic separating agent, puts the waste aluminum-plastic packaging into the container , and adds water and automatic separating agent. The aluminum-plastic packaging will completely separate the aluminum and plastic in about 20 minutes, each ton of waste. Aluminium-plastic packaging can separate 0.85 tons of recycled plastic and 0.1 tons of waste aluminum ? The daily recycling treatment of waste aluminum-plastic composite material 1 ton, the profit in 1000-2000 yuan?

6? Fireproof decorative board? Widely used in interior decoration? Ceilings? Furniture manufacturing, etc.? This product is not only colorful appearance, but also has a fireproof? Waterproof? Corrosion Insulation? Invariable? Not aging?

7? Recycled Granules? By using special granulation equipment, waste plastics such as polyethylene and polypropylene can be processed through the crushing-cleaning-plus-thermoplastic-extrusion process to produce the market's best-selling recycled pellets. A profit of 1 ton per day can be profitable. 300-500 yuan?

8? Production of grams? It is the upgrading of traditional waterproof material products, used on the surface of the house, just like brushing a layer of glass sodium, fast sealing, strong permeability, fast drying, fast plasticization, leveling performance Good, strong adhesion, acid and alkali resistance, service life of up to 20 years or more, and convenient construction, can be used throughout the year, no heating, no coating, low cost, high profit, cost per ton 2000 -3000 yuan, the market price of 5,000 yuan?

9? Production of plastic woven bags? Sangcai Town, Shanting District, Zaozhuang City, Shandong Province Uses abandoned white plastic products to process and produce plastic woven bags, which not only solves environmental pollution problems, but also increases farmers' income. Currently, plastics have been established in the town. There are 201 grain processing factories, 23 plastic woven bag factories, and 500 million woven bags of Nissan. The acquisition, transportation, processing and printing of scrap plastics have resulted in annual sales of 350 million yuan, and more than 6,000 rural laborers have become The town's farmers make a fortune to become a pillar industry?
