What is the best way of recycling plastic?

Nowadays, there are three main ways to recycle waste plastics: thermal pyrolysis recycling, melt recycling, and composite recycling. For investors, the most profitable and simple operation is the recycling method is thermal pyrolysis.

The following is an introduction and analysis of the three plastic recycling methods and video：

1. Thermal pyrolysis recycling
In this method, waste plastics are heated and decomposed into oil or gas, or used as energy or separated into petrochemical products by chemical methods. The working principle of waste plastic thermal pyrolysis plant is: the polymer is depolymerized at high temperature, and the molecular chain is broken and decomposed into smaller molecules and monomers, namely fuel oil and carbon black. For waste plastic raw materials, you hardly need to spend any manpower and material resources for processing.

The Plastic Fuel oil is the hottest alternative to petroleum in the market today. It is an industrial fuel with high calorific value and can be further refined into diesel by refining plant.

1) It can directly replace fuel oil for industrial or boiler heating, such as cement plants, steel plants, glass plants, stone brick plants, etc.;
2) Can be refined into diesel for diesel fuel and power plants, agricultural machinery, etc.

The obtained carbon black can be used for industrial heating by briquetting, and its combustion calorific value is equivalent to that of coal, and can be directly used instead of coal; in addition, it can be further ground and refined, and used as additives for paints, pigments, rubber products, etc.

2. Melt recycling
In this method, waste plastics are sorted, crushed, cleaned, and processed into plastic products by melting and plasticizing. For the waste products and scraps from resin production plants and plastic processing plants, various products with better quality can be produced by this method. The sorting and cleaning of waste plastics used in the society is more troublesome and the cost is higher. It is generally used to make coarse and low-grade products.

3. Composite reuse
This method is to crush waste plastics, such as PS foam products, PU foam, etc. into pieces of a certain size, and then mix them with solvents, adhesives, etc. to make lightweight boards and gaskets.

Combined with the current market environment, the national oil price is soaring, and the method of cracking plastic into fuel oil is not only profitable, but also easy to operate, safe and environmentally friendly. At present, it is the best choice for many investors to recycle waste plastics.
