Relevant experts pointed out that because waste plastics are rich in resources in China, low in recycling, it is a national support project (tax-free), and equipment investment is small, production process is simple, so China's waste plastic recycling has a lot of "money" way
At present, there are 9 ways to comprehensively utilize waste plastics at home and abroad:
1In the past few years, a new practical technology--waste plastic recycling fuel technology and process equipment has been successfully used in Chengdu. This waste plastic recycling factory uses waste plastics, such as food bags, waste woven bags, beverage bottles, plastic soles, wire and cable, foam, lunch boxes. Plastic toys, etc. produce high-quality 90# fuel, which has been tested by Sichuan Technical Supervision Bureau as qualified lead-free high-quality fuel. The company's strength is to use this oil, and 1 ton of waste plastic can produce about half a ton of oil.
According to experts, the cracking of discarded plastic into fuel oil has no technical problems, but in actual production, including Europe, America, Japan, etc., there are no reports and data recorded in China. This research can be done in the laboratory, but In practice, because the production cost is too high, it is difficult to produce economic benefits, so the large-scale production cannot be carried out, so the technical result born in Chengdu provides an effective and feasible new technology for the governance of “white pollution†in China.
2 Production of waterproof and anti-freezing adhesives Based on foamed plastic waste, special varieties and multi-purpose indoor and outdoor building decoration water-resistant adhesive glue series products are produced under special formula and process conditions, which is an investment with less effective and competitive. The ideal project for energy efficiency to eliminate plastic pollution can produce several tons of finished glue per ton of waste. According to the minimum package of 5kg×200 barrels per ton of glue, the comprehensive production cost is about 3,000 yuan, and the price is about 6000 yuan.
3 Preparation of aromatic compounds Japan is developing a new technology for the production of chemical raw materials using waste plastics as raw materials. The method is to heat waste plastics such as PEPP to 300 ° C, decompose them into carbohydrates, and then add catalysts. When aromatic compounds such as benzene toluene and xylene can be synthesized and reacted at a temperature of 525 ° C, 70% of waste plastics can be converted into useful aromatic substances, which can be used as raw materials for chemicals and pharmaceuticals and as fuel for gasoline. Agent, etc., the use of a wide range of other components can be converted to hydrogen and propane
4 Preparation of multifunctional resin glue This product has the characteristics of good adhesion, high gloss, high impact resistance, acid and alkali resistance, daily production of 1 ton, cost of 2,300 yuan per ton, market price of 5,000 yuan, industrial use in the production of various FRP products, It can greatly reduce the production cost. In addition, it can also produce waterproof paint anti-rust paint furniture putty glue and other products, which can replace various glass glue wood glue printing glue.
5 Aluminum-plastic automatic separating agent Aluminum-plastic composite packaging is widely used in food and pharmaceutical packaging. With the progress of society, waste is increasing year by year. Because of the combination of aluminum and plastic, it can not be granulated, and no one can recycle it. It can only be incinerated and polluted. The environment wastes resources by using aluminum-plastic automatic separating agent. The waste aluminum-plastic packaging is put into the container, water and automatic separating agent are added. The aluminum-plastic packaging will completely separate the aluminum-plastic in about 20 minutes, and the detachable aluminum-plastic packaging can be separated. Out of 0.85 tons of recycled plastic and 0.1 tons of waste aluminum, 1 ton of waste aluminum-plastic composite material is recycled and processed daily, and the profit is 1000-2000 yuan.
6 fireproof decorative panels are widely used in interior decoration ceiling furniture manufacturing, etc. This product not only has a bright and colorful appearance, but also has the characteristics of fireproof, waterproof, anticorrosive insulation, non-aging, and optional curling.
7 Recycled granules can use special granulation equipment to pass the waste polyethylene-polypropylene and other plastics through the crushing-cleaning-heating plasticizing-extrusion molding process to produce the market-selling recycled granules with a daily yield of 1 ton and a profit of 300-500 yuan.
8 Production of Keshiwang It is an upgraded product of traditional waterproof material. It is used on the surface of the house, just like applying a layer of glass sodium. It has strong sealing and high permeability. It has the characteristics of dry, rapid plasticization and fast leveling, and strong adhesion. It has the characteristics of acid and alkali resistance, service life of more than 20 years and convenient construction. It can be constructed all year round without heating. The cost of one coating is low, the profit is high, the cost per ton is 2000-3000 yuan, and the market price is 5000. yuan
9 Production of plastic woven bags Sangye Town, Shanting District, Zaozhuang City, Shandong Province uses discarded white plastic products to process and produce plastic woven bags, which not only solves environmental pollution problems, but also increases farmers' income. At present, the town has established plastic pellet processing factory 201 Home, plastic woven bag factory 23, Nissan woven bag 500 million, formed a waste plastics acquisition of transportation processing and printing one-stop, annual sales of 350 million yuan, absorbing more than 6,000 rural labor, become the town's farmers get rich Pillar industry
