High-molecular polymers form the chemical essence of materials such as plastics, rubber, and synthetic fibers. With over 400 million tons of polymer raw materials consumed each year globally, traditional mechanical recycling methods face fundamental bottlenecks when processing mixed, contaminated, and low-value polymer waste, including poor feedstock adaptability, product degradation, and untreatable residues.
Pyrolysis technology, represented by equipment manufacturers like Niutech, breaks high-polymer molecular chains into small-molecule products through thermal decomposition, and is emerging as a core pathway to solving polymer recycling challenges. For example, waste plastics can be converted through pyrolysis into oil—realizing a "plastic-to-oil" transformation—and can be further processed for deeper and broader applications based on demand.
In contrast to mechanical recycling, which is limited to single, clean plastic feedstocks and results in downgraded product quality with residual waste that cannot be fully treated, pyrolysis technology can handle mixed, contaminated, and low-value plastics, produces products with quality equivalent to virgin materials, achieves complete resource circularity without residual waste, and is theoretically applicable for infinite cycles. This technology is suitable for a wide range of polymers, including PE, PP, PS, ABS, nylon, and rubber.
Niutech is a technology-focused listed enterprise in China that has specialized in pyrolysis technology for over 30 years and stands as a leader in the field with core technological expertise. The company's self-developed "Industrial Continuous Organic Waste Pyrolysis Production Line" has been honored with the National Science and Technology Progress Award. The equipment achieves fully automated continuous operation—including continuous feeding, continuous pyrolysis, and continuous discharge—representing the most advanced technological pathway available and enabling industrial continuous operation of pyrolysis equipment under safe and environmentally compliant conditions. Building on this core, Niutech has developed comprehensive plastic recycling solutions. As of 2026, Niutech has successfully provided pyrolysis technology and equipment to dozens of countries and regions worldwide.
Niutech's pyrolysis technology and equipment not only achieve continuous feeding, pyrolysis, and discharge but also offer a single-unit annual processing capacity exceeding 10,000 tons, meeting the demands of large-scale production in market environments. The system utilizes the non-condensable combustible gas generated during pyrolysis as a heat source, achieving energy self-sufficiency and significantly reducing operational costs. Equipped with comprehensive exhaust gas purification systems, it complies with the most stringent environmental emission standards of the EU, the United States, and China.
Pyrolysis technology converts waste polymers into high-energy-density energy products such as pyrolysis oil and combustible gas, serving as an important component of waste-to-energy systems. The pyrolysis products achieve high yields and quality, and can be further refined into gasoline and diesel fractions or chemical feedstocks; solid residues can be refined and processed for use in the chemical industry.
A 10,000-ton-scale chemical recycling project invested in by the global chemical giant BASF employs Niutech's technology and integrated equipment. The project processes mixed waste plastics from a self-built waste treatment station and surrounding recycling facilities, producing high-quality pyrolysis oil through a continuous pyrolysis production line, which is subsequently used through deep processing to produce new plastics. This achieves a complete chemical recycling closed loop of "waste plastic → pyrolysis oil → chemical feedstock → new plastic."
As global policies continue to strengthen and industrial chain collaboration accelerates, pyrolysis technology and equipment will play an increasingly important role in polymer recycling, truly realizing the sustainable development goals of "waste-to-energy and resource circularity."
