Waste plastic resources are very rich, recycling is also very cheap, and equipment investment is small, the production process is very simple, so waste plastic recycling is a huge potential project.
Comprehensive utilization way:
First: recycled particles; using special shredder equipment, pelletizing equipment, etc., waste polyethylene, polypropylene and other plastics can be processed and produced by crushing, cleaning, heating, plasticizing and extrusion molding process to produce the best-selling recycled particles in the market. The daily profit of 1 ton is 300-500 (different prices in different regions)
Second: production of plastic woven bags;
Third: production of waterproof and antifreeze adhesive; based on foamed plastic waste, under special formula and process conditions, production of multi variety and multi-purpose indoor and outdoor building decoration water-resistant adhesive paste series products is an ideal project with less investment, quick effect, competitiveness and energy efficiency to eliminate plastic pollution. Each ton of waste material can produce several tons of finished rubber. Based on 5kg × 200 barrels per ton of small rubber packaging, the comprehensive production cost is about 3000 yuan, and the selling price is about 6000 yuan.
Fourth: preparation of multifunctional resin adhesive. The product has the characteristics of good adhesion, high gloss, strong impact resistance, acid and alkali resistance, with a daily output of 1 ton, a cost of 2300 yuan per ton and a market price of 5000 yuan. In industry, it can be used to produce various FRP products, which can greatly reduce the production cost. In addition, it can also be used to produce waterproof coating, antirust paint, home putty glue and other products, which can replace various glass glue, wood glue and printing glue.
Fifth: the production of aromatic compounds. Japan is developing a new technology of making chemical raw materials from waste plastics. Its award is to heat waste plastics such as PE and PP to 300 ℃, decompose them into carbohydrates, and then add catalysts to synthesize aromatic compounds such as benzene, 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, fuel improvers for gasoline, etc., and are widely used. The rest can be converted to hydrogen and propane.
