With the surge in plastic usage, plastic pollution has become a prominent environmental issue globally, highlighting the increasing necessity for plastic recycling. The accumulation of discarded plastics affects the quality of soil and water sources. According to statistics, over 300 million tons of plastic waste are generated worldwide annually, with more than 80% not effectively recycled, continuously exacerbating the waste of resources and environmental degradation. Urban waste management costs are also rising, and incineration and landfilling no longer meet future environmental protection requirements. Improving the efficiency of plastic recycling and reducing resource waste has become an urgent issue that needs to be addressed. Most plastic recycling technologies on the market currently face issues such as low efficiency, poor economic viability, and the potential for secondary pollution, which cannot effectively meet the demands for sustainable development and a circular economy. Niutech is a pyrolysis equipment manufacturing company from China. With 40 years of continuous technological accumulation, it has 10,000-ton commercial project cases in more than 50 countries worldwide, becoming an internationally renowned expert in continuous pyrolysis technology. It offers an innovative solution from plastic to oil, converting waste plastic into clean fuel oil through pyrolysis. After further processing, it can be used as a chemical raw material for the production of new plastics, achieving a true closed-loop chemical recycling of waste plastics.
The plastic pyrolysis process is a highly efficient technology for recycling waste plastics. Its principle is to convert the macromolecular polymers of waste plastics into small molecules in an oxygen-free or oxygen-deficient environment at a certain temperature. The pyrolysis products include fuel oil, gas, and monomers, among other intermediate chemicals. These products can not only replace fossil energy sources, which is beneficial for energy conservation and emission reduction, but also effectively address the low-value, mixed, and contaminated waste plastics that traditional mechanical physical recycling finds difficult to handle. This process alleviates the environmental pressure from plastic waste and paves a new path for sustainable development.
Processing waste plastic with pyrolysis technology can reduce carbon emissions per ton of raw material by 76.3% and carbon emissions per unit of output by 93.1%, achieving a significant reduction in carbon emissions. Compared to traditional incineration and landfill equipment, Niutech’s plastic pyrolysis equipment has a lower investment cost and a higher degree of automation, making operations simpler and more efficient. This system can break down the organic polymers in waste plastic into small molecules through precise temperature control heating, forming high-quality fuel oil and solid fuel, thus achieving efficient recycling of waste plastic.
Niutech’s plastic pyrolysis technology is conducted under high-temperature and oxygen-deficient conditions. Through indirect heating, the entire production line is in a closed state throughout the process. It is equipped with eight major systems, including intelligent feeding, intelligent pyrolysis, oil cooling, and flue gas purification, achieving safety and environmental protection in the pyrolysis process. The environmental protection indicators meet the standards of the US EEA and the EU’s EPA. Currently, this technology has successfully implemented 10,000-ton commercial projects in Denmark, Thailand, South Korea, and China. Through actual operation results, Niutech’s technology reliability and stability have reached world-class standards, providing an advanced example for the international pyrolysis chemical recycling field.
With the increasing global focus on sustainable development and dual-carbon goals, the application prospects of Niutech’s waste plastic pyrolysis process and equipment in the field of resource regeneration are broad.
