The current plastic pollution problem is becoming increasingly serious, causing great pressure on the global environment. Plastics belong to artificially manufactured polymer compounds with strong chemical stability and impact resistance, which makes the environmental treatment of waste plastics a difficult problem. Currently, the United States generates over 32 million tons of plastic waste annually, and Europe also has 25 million tons each year. In addition to the types of plastics suitable for physical recycling, there is still a large amount of low-value, mixed, and contaminated plastics that cannot be effectively treated. In this context, how to convert plastic waste to energy through pyrolysis technology has become a key issue in the field of environmental protection. Pyrolysis technology is an effective technology for chemical recycling. Through pyrolysis conversion, plastic wastes can be turned into high-value-added fuel oils or chemical raw materials, which helps plastic recycling and realizes the application of high-value-added resources. The principle of plastics recycling pyrolysis technology is the process of decomposing plastic waste by heating it under oxygen-deficient or oxygen-poor conditions to obtain products such as liquid fuel, gas fuel, and solid carbon residue. In this process, high molecular weight plastics are converted into low molecular weight hydrocarbons through pyrolysis reaction to realize 100% resource utilization.

For the practical application of plastic pyrolysis technology, the level and capability of equipment design are crucial. Traditional batch pyrolysis equipment has issues such as discontinuous feeding, difficulty in controlling the reaction time, and inadequate safety and environmental protection, which are significant reasons why it is difficult to achieve large-scale operation. Niutech from China is a global expert in continuous pyrolysis technology. As a professional pyrolysis equipment manufacturer and an integrated solution provider, Niutech has independently developed the “Industrial Continuous Waste Plastic Pyrolysis Production Line”, which has won the highest award in China’s environmental protection technology – the State Scientific and Technological Progress Award. It adopts a spiral sealing feeding method, achieving dynamic sealing of feed and discharge, greatly improving the stability of large-scale pyrolysis projects and product quality. At the same time, the entire set of equipment significantly improves the pyrolysis efficiency by precisely controlling dozens of parameters such as reaction temperature and residence time. It can flexibly adjust the structure of product output to meet the needs of different customers.Through Niutech’s waste plastic recycling equipment, all kinds of mixed waste plastics can be converted into high-quality fuel oil. Subsequently, through the company’s abundant high-value application solutions, high-quality fuel oil can be further refined into naphtha, which becomes the chemical raw material for the production of new plastics. This continuous pyrolysis technology not only improves operational efficiency but also facilitates the realization of fully automated control, which significantly reduces labor costs. At present, the continuous waste plastic production line of Niutech has realized 10,000-ton projects in Denmark, Thailand, South Korea, and other countries. Compared with the traditional incineration or landfill method, using continuous pyrolysis technology to treat waste plastics not only greatly reduces the operation cost, but also realizes the high-value utilization of resources, creating considerable economic benefits for the project.

In the future, with the continuous promotion of Niutech’s pyrolysis technology, it will become the key support in the field of global chemical recycling of plastics. It will help realize the transformation of waste plastics into high-value-added products and drive the upgrading of the whole industry value chain. It is believed that in the near future, this green, efficient, recycling and environmentally friendly technology will contribute more to the utilization of global plastic resources and the realization of carbon-neutral goals.
