As a key technology for solving plastic pollution and promoting the circular economy, chemical recycling of plastics is facing unprecedented development opportunities. However, in its journey toward large-scale commercialization, this industry still confronts multiple challenges in technology, economics, policy, and industrial chain integration.

I. Core Challenges Facing Chemical Recycling of Plastics
1. Difficulty in Achieving Continuous and Stable Operation
The greatest bottleneck to the industrialization of pyrolysis technology is achieving continuous and stable operation of the equipment. Many pyrolysis projects globally operate below their designed capacity, fundamentally due to unresolved industry-wide challenges such as reactor coking, difficulties in dynamic sealing during feeding and discharge, and product polymerization.
2. Limited Feedstock Adaptability
There are over 200 different types of plastics, ranging from commodity plastics to specialty and engineering plastics. Different plastics exhibit vastly different pyrolysis characteristics, requiring varying process parameters. Moreover, real-world collected waste plastics often contain impurities, additives, colorants, and other contaminants, further increasing the difficulty of processing.
3. Product Quality and Subsequent Processing
The quality of the pyrolysis oil produced directly affects its value for subsequent use. If the impurity content in the pyrolysis oil is too high, it cannot be directly fed into refineries for deep processing without additional purification and upgrading steps, which increases process complexity and cost.
4. Feedstock Cost and Supply Instability
The lack of a stable, standardized upstream plastic waste source is a primary challenge to the industrialization of chemical recycling. In many regions, waste plastic collection suffers from dispersed sources, mixing with other waste, and small-scale, workshop-style operations, making it difficult to coordinate resources and markets across sectors and regions. Collection scale is severely limited, and sorting levels are low, affecting the efficiency and quality of subsequent treatment.
5. Incomplete Policy and Standards
Chemical recycling projects lack clear policy support in areas such as project approval, environmental supervision, and product certification. Relevant tax incentives do not adequately cover the mid- and downstream parts of the industrial chain, and the scope of production and application of recycled plastic products remains unclear.
II. Niutech’s Successful Experience
Through nearly 40 years of technological accumulation, Niutech has independently developed eight core technologies, including “thermal dispersion, gas-tight sealing, and anti-polymerization,” successfully overcoming world-class challenges such as system coking, difficulties in dynamic sealing during feeding/discharge, and product polymerization. Its “Continuous Pyrolysis System,” which has been honored with the National Science and Technology Progress Award, achieves precise temperature-controlled heating and rapid conversion of waste plastics within a fully enclosed production line, producing high-quality pyrolysis products suitable for deep processing.
Niutech’s self-developed “Integrated Low-Temperature Pyrolysis Technology and Equipment for Resource Utilization of Waste Plastics” can process low-value mixed waste plastics, medical waste plastics, marine waste plastics, and other categories that are difficult for mechanical recycling to handle. For low-value waste plastics, which account for 46% of total plastic waste, Niutech’s technology provides an efficient, low-carbon chemical recycling pyrolysis solution.
Niutech has explored and formed an innovative model of “integrating technology and equipment with industrial development synergy.” For example, in a high-end chemical recycling plant project in Vietnam, an internationally renowned group selected Niutech’s “New Generation • Large-Scale Industrial Continuous Intelligent Waste Plastic Pyrolysis Technology and Integrated Equipment” to build a plant in Vietnam. Using industrial plastic waste as feedstock, the project converts waste plastics into high-quality pyrolysis oil, which is directly used in the client’s own chemical plant for subsequent processing, successfully achieving a complete “waste plastic-to-new plastic” chemical recycling closed loop. The pyrolysis oil is directly converted into plastic monomers and then into new plastics within the client’s own facilities, completely eliminating transaction costs and uncertainties from intermediate steps. This approach reduces dependence on fossil energy while significantly cutting carbon emissions.
Niutech’s technology and integrated equipment have obtained seven major international certifications, including EU CE, German TÜV, ATEX explosion-proof, and ISCC International Sustainability and Carbon Certification. Among these, the ISCC certification is particularly critical, as it means that the pyrolysis products manufactured using Niutech’s technology meet the stringent requirements for entering the global high-end green renewable energy market, can participate in international carbon market trading, and can obtain a green premium.
III. Development Prospects: Moving Toward Scale, Efficiency, and Greenness
According to the latest industry data, the market is projected to soar to $17.5 billion by 2032, with a compound annual growth rate of 28%. This significant growth trajectory indicates that chemical recycling is becoming a core pathway for solving global plastic pollution and achieving closed-loop sustainable development.
Globally, over 120 countries have introduced relevant policies and regulations to strengthen plastic recycling. The EU has issued the Packaging and Packaging Waste Directive, requiring that at least 50% of plastic packaging be recycled starting in 2026. In the future, chemical recycling of plastics will move toward larger scale, higher efficiency, and greater environmental sustainability.
Chemical recycling of plastics is now at a critical turning point from “technically feasible” to “economically viable.” Chinese enterprises represented by Niutech, by overcoming the challenge of continuous operation, building full-industry-chain closed loop, and obtaining international certifications, have provided a verifiable, replicable, and scalable solution for industrial development.
