The governance of white pollution has become one of the core challenges in global ecological protection. A report by the United Nations Environment Programme shows that the global cumulative amount of plastic waste has exceeded 1 billion tons, with annual climbing to 350 million tons, posing a severe ecological threat. Plastic waste takes hundreds of years to degrade in the natural environment, not only causing soil compaction and microplastic pollution in water bodies, but also threatening human health through the food chain. Against this backdrop, pyrolysis technology, as a key technical path for “reduction, recycling, and harmlessness,” is becoming the core means to solve the problem.

As a leading Chinese enterprise in pyrolysis, Jinan Niutech Environmental Protection Technology Co., Ltd. has been deeply engaged in pyrolysis technology for organic waste for more than 30 years. Its independently developed continuous plastic waste pyrolysis equipment has won the highest award in China’s environmental protection science and technology — the National Science and Technology Progress Award — for its innovation and practicality, becoming a benchmark product in the global pyrolysis equipment field. Based on the principle of thermal instability of plastic macromolecules, the technology realizes the cleavage and conversion of macromolecules through precise temperature-controlled heating in an oxygen-free/anaerobic closed environment, converting plastic waste into high-value-added products such as pyrolysis oil and solid fuels. Through Niutech’s proprietary high-value application scheme, these products can be transformed into chemical raw materials for the production of new plastics, practicing the concept of circular economy of “turning waste into treasure” throughout the process.

Compared with traditional disposal processes, Niutech’s continuous pyrolysis equipment for environmental protection demonstrates three core advantages: In terms of environmental performance, as a representative equipment for chemical recycling, it adopts a fully enclosed micro-pressure system, achieving no dust release, no coking, and no dioxin generation. The emitted gas can meet the standards of the European Environment Agency (EEA) and the U.S. Environmental Protection Agency (EPA) after multi-stage purification. In terms of energy utilization, the original thermal dispersion and flue gas waste heat recycling technology converts non-condensable combustible gas and high-temperature flue gas system into heat sources, improving heating efficiency by more than 30% and significantly reducing energy consumption per unit of treatment. In terms of intelligent control, the entire system is equipped with a PLC/DCS intelligent platform, which monitors nearly 10,000 core parameters such as pyrolysis temperature and pressure in real time, and realizes adaptive adjustment combined with intelligent algorithms to ensure the stability of large-scale pyrolysis equipment operation.

As an upgraded product of pyrolysis equipment, Niutech’s continuous environmental protection system has completely solved the bottlenecks of productivity, energy consumption, and product stability of intermittent equipment. It realizes continuous feeding, discharging, and slag discharge through modularization, and the treatment efficiency is more than 5 times that of traditional equipment. This scale advantage has enabled Niutech to take the lead in completing the industrialization of large-scale projects in the United States, the United Kingdom, South Korea, and Germany, which have been listed as circular economy demonstration projects by local governments.

With the advancement of the global “Plastic Convention,” cross-border governance of plastic waste ushered in new opportunities. Niutech Environmental Protection is using technology output as a link to promote advanced pyrolysis technology from the laboratory to industrial application. Niutech’s continuous pyrolysis equipment not only sets a benchmark for Chinese environmental protection enterprises to “go global,” but also takes practical actions to promote the integration of plastic waste pyrolysis technology into the global ecological governance system, practicing the global concept of pollution governance of “harmonious coexistence between man and nature.” Looking forward, Niutech Environmental Protection will focus on the dual-carbon goals, continue to tackle key technologies such as low-consumption green pyrolysis and high-value conversion, and further improve resource recovery efficiency and commercial added value. Chinese equipment is reshaping the new pattern of global plastic waste governance with the power of innovation.
