Over 500 million tons of plastic waste are generated globally each year, among which low-value, mixed, and contaminated plastics account for 40% to 70%, and there has long been a lack of effective treatment methods. The chemical recycling technology for waste plastics refers to breaking down the high molecular polymers in waste plastics into small molecules through chemical methods to produce high-value chemical products, which can then be further processed into recycled plastics for commercial products, forming a complete circular closed-loop. It not only effectively supplements traditional physical recycling technologies but also avoids the downgrading of materials, holding enormous value potential in terms of the circular economy and carbon emission reduction. According to research and analysis by foreign professional institutions, it is conservatively estimated that the global market scale of chemical recycling for waste plastics could reach trillions of yuan in the future.
Niutech’s industrial continuous pyrolysis technology for waste plastics decomposes the high molecular polymers in waste plastics into small molecular products such as pyrolysis oil, solid fuels, and non-condensable combustible gases by precisely controlling temperature and reaction conditions. This technology solves the industry-wide problems existing in traditional pyrolysis technologies, such as coking in the pyrolysis system, difficulty in sealing for feeding and discharging, and polymerization of products, realizing safe, environmentally friendly, continuous, and stable industrial operation. The characteristics of this complete production line are as follows:
01 Continuous and efficient processing: It can handle various low-value, mixed, and contaminated waste plastics on a large scale and continuously, with large processing capacity and high production efficiency.
02 Compliance with European and American emission standards: The exhaust gas undergoes strict purification treatment, and all emission indicators are better than international standards, achieving harmless emissions.
03 Reliable and safe operation: The adoption of proprietary hot gas-tight technology, non-coking technology, etc., ensures safe and reliable operation of the equipment and prolongs its service life.
04 High-quality output: The produced pyrolysis oil, solid fuels, and other products have stable quality and can be used as chemical raw materials for producing new plastics, realizing peer-level and high-value utilization.
05 Low operating cost: The waste heat recycling technology is adopted to reduce energy consumption; the equipment has a high degree of automation, requiring fewer personnel and resulting in low labor intensity.
At present, Niutech’s comprehensive solution for waste plastics has been successfully applied in industrialization in many countries such as the UK, South Korea, Denmark, Thailand, Vietnam, as well as in China, creating benchmark projects including “European Waste Plastic Pyrolysis Chemical Recycling Demonstration Project”, “Asian Waste Plastic Pyrolysis Chemical Recycling Demonstration Project”, and “China’s first large-scale continuous medical waste plastic pyrolysis project”. The reason why Niutech’s technology has repeatedly gained customer recognition is that the chemical recycling technology for waste plastics is an industry with extremely high technical thresholds. When customers choose technical equipment suppliers, they need to conduct comprehensive, systematic, and multi-level considerations. However, what Niutech provides to customers is not only large-scale continuous production lines but also a set of comprehensive solutions that have been repeatedly tested in domestic and foreign markets, certified by international authoritative institutions, and have significant economic and environmental benefits.
