In today’s world faced with increasingly severe plastic waste pollution, how to effectively recycle and utilize waste plastics has become a critical issue. Pyrolysis technology, as an emerging waste plastic recycling method, has garnered significant attention. I will take DOING pyrolysis technology as an example to show you how pyrolysis technology can improve the recycling value of waste plastics.

The Principle of Pyrolysis Technology

Pyrolysis refers to the process of decomposing waste plastics into smaller molecules under high temperatures (typically between 300°C and 600°C) in an oxygen-free environment. During this process, waste plastics undergo thermal cracking, transforming into high-value products such as fuel oil, carbon black, and non-condensable gases similar to natural gas. Unlike traditional waste plastic recycling methods like landfilling and incineration, pyrolysis not only effectively addresses waste plastic issues but also generates economically valuable products, offering dual benefits for environmental protection and the economy.

The Value of Pyrolysis in Waste Plastic Recycling

High Efficiency Conversion

DOING’s pyrolysis technology excels in its high-efficiency conversion of waste plastics. The equipment operates under anaerobic conditions at high temperatures to decompose waste plastics into fuel oil and other chemicals. It effectively handles various types of waste, including plastics, municipal solid waste, tire rubber, and biomass materials.

For high-quality plastics such as PP, PE, and PS, DOING pyrolysis equipment achieves exceptionally high conversion rates, with oil yields exceeding 80%. Even when processing mixed plastic materials, the oil yield remains at least 50%, along with approximately 20% to 30% carbon black powder. This high conversion rate significantly enhances the recycling efficiency of waste plastics, enabling the production of more valuable products from the same amount of waste.

Valuable Products

By adjusting the pyrolysis temperature gradient of DOING’s pyrolysis equipment, plastic waste can be efficiently converted into high α-olefin content oil (HFO), which holds high economic value. Plastic pyrolysis oil serves as a high-quality industrial heating fuel, widely used in boilers, glass factories, steel mills, cement plants, and other industries. Carbon black, another byproduct, is a key material in the rubber industry, particularly in tire manufacturing. It also finds applications in the plastics, ink, coatings, and other sectors as a reinforcing agent, coloring agent, or conductive material. With the development of the new energy industry, its use in lithium batteries and other fields is becoming increasingly prominent.

Moreover, pyrolysis oil can be further refined into high-quality diesel using DOING waste oil distillation equipment. This diesel can be utilized in power generation, mining machinery, agricultural equipment, and more, further expanding the application scope and economic value of pyrolysis products.
