Prospects of plastic recycling industry

Plastic is a widely used material not only in everyday life but also in industrial production. However, the extensive use of plastic products has also brought some environmental problems, such as plastic pollution. In order to solve these environmental problems, plastic recycling has become one of the important environmental protection actions. Plastic recycling can be divided into physical recycling and chemical recycling. Physical recycling refers to processing waste plastic products into reusable pellets by means of classification, washing, crushing, etc., and making new plastic products in industrial production. Chemical recycling refers to recycling waste plastics through special processing methods, decomposing plastics into molecules or compounds, and reproducing new plastics. Through the recycling and reuse of plastics, the effective use of waste plastic resources can be realized and the pollution to the environment can be reduced. At the same time, since plastic is a very durable material, recycling can also help save resources and energy, reduce the production cost of enterprises, and improve economic benefits. When it comes to recycling, plastics can be used to make a myriad of items, including bags, bottles, pipes, tubing, and more. Discarded plastics can be recycled into various plastic products and put into use again, so as to reduce waste of resources, reduce environmental pollution, and reduce logistics costs. In general, plastic recycling is a very important environmental protection action. It can not only effectively reduce plastic pollution, but also drive economic development and consumption to reduce waste and promote sustainable development. Therefore, we should increase investment in plastic recycling, promote the use of environmentally friendly plastic products, and jointly contribute to a better environment and society.

The first step: waste plastic classification collection.

The waste plastics in the plastic production and processing process have a single variety, no pollution and aging, and can be collected and processed separately. Waste plastic mineral water bottles, Coke bottles, agricultural PVC films, PE films, PP woven bags, packaging bags, PVC cable sheathing materials, etc. can also be collected and processed separately.

Most of the waste plastics are mixed wastes. In addition to the complex types of plastics, they are also mixed with various pollutants, labels and various composite materials. The specific classification method can be seen in the following introduction

Step 2: Crushing and sorting.

According to its nature, the appropriate crusher is selected, using electrostatic method, magnetic method, screening method, wind method, specific gravity method, floating beneficiation method, color separation method, X-ray separation method, near infrared separation method and other methods to break and separate waste plastics.

Further treatment methods include crushing, washing, separation and drying. Further processing is done by shredding the material into small pieces. These fragments still contain little residue of the original material, such as shredded paper labels and plastic covers. When these are removed by different methods, they become pure PET fragments or PET flakes. PET flakes are used as raw materials in some products made from polyester, examples include polyester fibers for the production of clothing, pillows, carpets, etc., as a base material, polyester sheets, strapping straps, or new bottles.

PET polymers are very sensitive to hydrolytic degradation after melting, resulting in a severe reduction in their molecular weight. Therefore, PET flakes or particles must be dried to very low moisture content before melting extrusion. PET must be dried to <100 parts per million (ppm) of moisture and kept at that level to minimize hydrolysis during melt processing, so dehumidifying dryers are very important, these dryers circulate hot and dehumidified dry air to the material, draw the air back and then dry it again, pumping it again in a closed loop operation. This method reduces the water content in PET to less than 50ppm. The dehumidification effect depends on the air humidity, if the air humidity is not good, there will be some moisture residue during the processing, resulting in loss of yield. [4] In recent years, infrared drying (IRD) technology has been used to invent a new type of dryer, because the infrared heating energy transfer rate is high, the specific wavelength used makes the energy cost greatly reduced, amorphous sheets crystallize and dry in about 15 minutes, reaching a humidity level of about 300ppm, and then drop to <50ppm using a buffer hopper. Drying is completed within 1 hour, so most manufacturers use infrared dryers.

These fragments next go into the furnace, and melt filters are usually used to remove debris from the polymer melt during the outflow process. The mechanical separation mechanism of contaminants exists in machines called "filters". Typical systems use a steel body housing, and the heat-resistant filter is contained in a removable piston or slide, allowing the processor to replace the screen from the extruder process without stopping production. Contaminants typically collect in heat-resistant filtration nets, which are supported on stainless steel plates called "fracture plates," which are large round steel plates with large holes drilled to allow the polymer melt to flow. After the PET recycling begins, usually the entire filter is in a product line, and the resulting melt is directly shot into the new product forming machine without cooling, such as granulation, sheet extrusion, strapping tape, etc.

The third step: recycling resources.

1. Make fuel oil. The use of such as food bags, waste woven bags, beverage bottles, plastic soles, wire and cable leather, foam lunch boxes, plastic toys, etc., to produce high-quality 90 # fuel, 1 ton of waste plastic can produce about half a ton of oil.

2, the production of waterproof and antifreeze glue. With foam plastic waste as the base material, under special formula and technological conditions to produce multi-variety, multi-purpose indoor and outdoor building decoration water-resistant adhesive liquid series products, each ton of waste can produce several tons of finished adhesive

3. Prepare aromatic compounds. The method is to heat the waste plastic such as PE and PP to 300 ° C, decompose it into carbohydrates, and then add a catalyst to synthesize benzene, toluene and xylene and other aromatic compounds. When reacting 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 fuel improvers for gasoline, etc., and have a wide range of uses. The remaining components can be converted to hydrogen and propane.

4, prepare multi-functional resin adhesive.

5, for aluminum-plastic composite materials using aluminum-plastic automatic separation agent, aluminum-plastic packaging will be completely separated in about 20 minutes, each ton of waste aluminum-plastic packaging can be separated from 0.85 tons of recycled plastic and 0.1 tons of waste aluminum.

6, fire decorative board.

7, the use of special granulation equipment, waste polyethylene, polypropylene and other plastics through the crushing - cleaning - heating plasticization - extrusion molding process, processing and production of market-selling recycled particles.

8, the production of the leakage king for the surface of the house, the anti-leakage performance is very strong.

9, production of plastic woven bags.

10, plastic bottles can be turned into chemical fiber material, this material can replace cotton, as a quilt pillow and other fillers, can also be processed into a kind of clothing raw materials, some foreign countries in this area of technology is very strong, so they often need to import plastic bottles to make clothes.

11, composite materials, plastic bottles only need to go through a few processes, can become a wood-plastic composite material, this material can be effectively used in some construction industries, as well as the transportation industry, very wide range of uses.
