Waste plastic pyrolysis technology, as a core pathway of chemical recycling, is becoming a critical solution for addressing “white pollution,” achieving resource circularity, and supporting “dual-carbon” goals globally. This process converts plastics—a final product of the petrochemical industry—back into initial fuels or chemical feedstocks, realizing a fundamental shift from “waste” to “resource.”
I. Waste Plastic Pyrolysis Technology
The scientific basis of pyrolysis lies in the thermal instability of organic materials. Heating in oxygen-free conditions effectively suppresses the formation of toxic substances such as dioxins, avoiding the environmental risks associated with incineration at the source. Among pyrolysis methods, low-temperature pyrolysis—primarily yielding liquid oil—has become the mainstream industrial approach for plastic resource recovery due to its versatile outputs and lower energy consumption.
1. The significance of this technology extends far beyond simple waste treatment; it represents a revolution in resource recovery and environmental governance. Environmental Impact: It provides an ultimate solution for processing low-value, compositionally complex plastics that are challenging for mechanical recycling—such as flexible packaging and films—reducing plastic pollution at the source while significantly cutting carbon emissions.
2. Resource Value: Converting waste plastics into oil and combustible gas is akin to developing “urban oil fields,” effectively reducing dependence on imported crude oil.
3. Economic Benefits: Pyrolysis products hold high value, with both pyrolysis oil and combustible gas offering substantial economic returns.
II.Global Benchmark Pyrolysis Projects: Niutech’s Technological Contributions and Leading Case Studies
Among numerous enterprises, Jinan Niutech Environmental Technology Co., Ltd. has emerged as a “Chinese hallmark” in the global high-end pyrolysis sector through its deep technical expertise and successful international projects. Its core advantage stems from decades of dedicated R&D, resulting in eight independently developed core technologies, including “thermal dispersion, gas-tight sealing, and anti-polymerization,” which enable safe, stable, and continuous pyrolysis operations with single-startup long-term stability far exceeding industry averages. Its production lines are equipped with intelligent control systems capable of real-time monitoring and adjustment of nearly 20,000 technical parameters, ensuring efficient operation at a 10,000-ton processing scale.
Niutech’s technological capabilities have been rigorously validated in international high-end markets, with its projects serving as industry benchmarks:
1. Vietnam High-End Chemical Recycling Plant Project:
After a global evaluation, an internationally renowned group selected Niutech’s “New Generation • Large-Scale Industrial Continuous Intelligent Waste Plastic Pyrolysis Technology and Integrated Equipment” to build a factory in Vietnam. Using industrial plastic waste as feedstock, the project converts waste plastics into high-quality pyrolysis oil, which is directly supplied to the client’s own chemical plant for further processing, successfully achieving a complete “waste plastic-to-new plastic” chemical recycling closed loop. The project has been commissioned and has operated efficiently and continuously for several months, earning high praise from the client, with expansion and replication plans currently underway.
2. Denmark BASF Chemical Recycling Project:
Niutech’s technology and equipment were earlier applied in a Danish waste plastic pyrolysis project, which received investment and recognition from the international chemical giant BASF—an early standout achievement in Niutech’s deep engagement with international high-end markets.
3. UK Large-Scale Waste Plastic Pyrolysis Resource Recovery Project:
A major UK project employing Niutech’s advanced technology is progressing smoothly, further demonstrating the adaptability and reliability of its solutions across diverse markets and regulatory environments.
Niutech’s technology and equipment have obtained certifications such as EU CE and German TÜV, with project-level ISCC certification, and have been exported to dozens of countries and regions worldwide, including the United States, Germany, the United Kingdom, Denmark, South Korea, and Brazil.
The success of Niutech lies not only in providing advanced equipment but also in delivering verifiable, replicable, and scalable end-to-end green recycling solutions. By overcoming industrialization bottlenecks in continuous operation and successfully integrating pyrolysis oil into downstream chemical production chains, it truly demonstrates the closed-loop value of chemical recycling. As more international benchmarks like Niutech’s projects are implemented and global demand for a low-carbon circular economy grows, waste plastic pyrolysis technology is poised to contribute even more “Chinese wisdom” and “Chinese solutions” to global sustainable development.
