Traditional plastic treatment methods primarily include landfilling, incineration, and mechanical recycling, yet each exhibits significant limitations: Landfilling requires vast land resources and risks contaminating soil and groundwater; incineration releases toxic substances such as dioxins while generating substantial carbon emissions; mechanical recycling, though partially effective, involves repeated melting that fractures molecular chains, leading to irreversible degradation in material performance, ultimately resulting in disposal via landfilling or incineration.
Confronting this global challenge, chemical recycling of plastics is rapidly emerging as the core engine to address white pollution. Unlike traditional methods, chemical recycling can convert waste plastics into original monomers or high-value-added chemicals, achieving true circular utilization. In recent years, technological innovations have driven revolutionary progress, with waste pyrolysis technology garnering particular attention for its ability to process mixed and contaminated plastic waste without complex sorting or cleaning processes, significantly enhancing recycling efficiency and economic viability.
Niutech has gained extensive recognition in global high-end markets through its industrial continuous waste plastic pyrolysis technology. On August 20, 2025, the company announced a contract valued at RMB 198 million with a UK client for a 60,000-ton/year industrial continuous waste plastic pyrolysis production line. This collaboration underscores international recognition of and demand for advanced chemical recycling technologies, while demonstrating the technical prowess and leadership of Chinese enterprises in the global environmental protection sector.
The core of chemical recycling technology lies in decomposing plastic polymers into small-molecule compounds through thermochemical processes, which can then be repurposed into various chemical raw materials and fuels. Among the numerous technological pathways, pyrolysis stands out as the most mature and industrially applied. Niutech’s “Industrial Continuous Intelligent Pyrolysis Process” represents the cutting edge in this field, having been awarded the National Science and Technology Progress Award, and enabling deep resource utilization of low-value, mixed plastic waste, including municipal, oceanic, and medical plastic waste.
Niutech’s technological breakthroughs primarily address a series of bottlenecks in pyrolysis industrialization. The “continuous operation” of large-scale pyrolysis equipment is a widely acknowledged challenge in the industry, with most newly built global pyrolysis projects operating below their designed capacity. The root cause lies in the fact that most technology providers remain at the experimental or pilot stages, lacking equipment capable of meeting industrial-scale continuous operation requirements, and offering no mature or effective solutions to industry-wide issues such as system coking, dynamic sealing during feeding and discharge, and product polymerization.
Niutech’s technology and integrated equipment have been exported to dozens of countries worldwide, cumulatively processing tens of millions of tons of organic waste.
In Europe, Niutech boasts highly representative projects, including a contract with Norway’s Quantafuel for waste plastic pyrolysis production lines used in a Danish waste plastic pyrolysis plant, which received investment and high recognition from the international chemical giant BASF.
A waste plastic pyrolysis project invested by South Korea’s Hyundai Group in Southeast Asia has successfully commenced operations and is running stably. Fully equipped with Niutech’s waste plastic pyrolysis technology, the project achieves the transformation from “plastic to oil,” with the resulting pyrolysis oil used as feedstock for chemical recycling in Hyundai’s own chemical plants in South Korea, contributing to carbon emission reduction.
Chemical recycling technology for waste plastics holds profound significance in advancing the circular economy, serving as a critical technical foundation for building “zero-waste cities” and achieving sustainable development. This plastic recycling solution, based on chemical recycling technology, enables plastic waste to once again become raw material for new plastic production, truly realizing the transformation from “waste to resource.”
