Against the backdrop of escalating global plastic pollution, the chemical recycling of waste plastics has emerged as a critical solution to address the challenge of “white pollution.” Niutech Environment Technology Corporation has achieved groundbreaking progress through its self-developed industrial continuous waste plastic pyrolysis technology. By converting waste plastics into sustainable energy and chemical raw materials, the company has established a closed-loop circular economy model of “resources-products-renewable resources” in fields such as plastic-to-oil machinery, waste-to-energy systems, and high-value utilization of pyrolysis products.

I. Principles of Plastic Pyrolysis and Niutech Technological Innovations
Plastic pyrolysis is a technology that decomposes high-molecular polymers into small-molecular products under high-temperature anaerobic or oxygen-deficient conditions. By precisely controlling key parameters such as heating temperature, heat transfer area, and residence time, components like PP, PE, and PS in waste plastics are cracked into pyrolysis oil, non-condensable gas, and solid fuels, enabling molecular-level resource regeneration.

Niutech industrial continuous waste plastic pyrolysis production line incorporates multiple innovations over traditional pyrolysis technologies:
1. Continuous Process: A dynamic sealed feeding system and continuous discharge design resolve the inefficiencies of intermittent equipment, reducing energy consumption and coking risks while improving overall efficiency by over 30%.
2. Precision Temperature Control: Proprietary technology ensures uniform heating of materials, prevents secondary cracking, and significantly increases pyrolysis oil yield.
3. Eco-Safe Design: Fully enclosed production processes eliminate dust and VOC emissions, with discharge metrics meeting international standards and carbon emissions reduced by 50% compared to incineration.

II. High-Value Applications of Pyrolysis Products
Niutech pyrolysis outputs—pyrolysis oil, solid fuels, and non-condensable gas—serve diverse applications:
Pyrolysis Oil: Further processed into ethylene, propylene, and other chemical raw materials or blended into gasoline/diesel. For instance, a Thailand project directly uses pyrolysis oil as vehicle fuel, achieving energy self-sufficiency.
Solid Fuels: Utilized as industrial boiler fuel or backfill materials. For example, reduced soil from Xinjiang’s oil-sludge project is applied in road construction.
Non-Condensable Gas: Powers self-sustained heating for production lines, minimizing external energy dependence through internal recycling.

Studies indicate that each ton of chemically recycled plastic reduces carbon emissions by 2.3 tons compared to virgin materials, delivering dual economic and environmental benefits.

III. Global Benchmark Projects: From Technical Validation to Commercialization
Niutech waste plastic pyrolysis technology has been successfully implemented in domestic and international projects, demonstrating technical prowess and commercialization capabilities:
1. Denmark Chemical Recycling Project
Funded by global chemical giant BASF, this project uses Niutech pyrolysis equipment to process mixed waste plastics. The resulting pyrolysis oil feeds new plastic production, forming a closed-loop cycle recognized internationally as a model for chemical recycling.

2. Thailand Plastic-to-Fuel Project
Pyrolysis oil is refined into gasoline and diesel fractions to fuel corporate vehicle fleets, validating its viability as an alternative fuel.

3. Industrial Applications in China
Multiple 10,000-ton scale projects in China address mixed contaminated plastics in municipal waste, medical waste plastics, and industrial plastic residues.

Niutech continues to expand pyrolysis applications from waste plastics to tires, biomass, medical waste, and other domains while advancing intelligent upgrades in waste-to-energy systems. As global emphasis on plastic circular economy grows, this technology holds promise as a key solution for marine plastic pollution and urban solid waste management.

Through innovations in plastic-to-oil machinery and waste-to-energy systems, Niutech transforms waste plastics from environmental burdens into “urban oil fields,” showcasing technology’s potential to empower sustainability. Its global project portfolio and robust technical expertise not only set industry benchmarks but also provide replicable Chinese solutions for achieving “zero-waste cities” and carbon neutrality goals.
