Plastic waste is ravaging the planet with severe “white pollution”. Humanity has developed three recycling paths to combat this crisis:
1. Mechanical Recycling: Melts and re-pellets plastics. Limitation: Only works for pure, single plastics (e.g., PET bottles); fails with mixed/contaminated waste.
2. Energy Recovery: Incineration for power. Drawback: Releases dioxins and heavy metals, causing secondary pollution.
3. Chemical Recycling: Centers on plastic pyrolysis. Breaks mixed waste into molecular components, converting it to fuel/chemical feedstocks. Achieves true “waste-to-resource” circularity. This makes chemical recycling sustainable.
In this plastic rebirth revolution, innovators like China’s Niutech drive chemical recycling from labs to global industry—powered by continuous pyrolysis systems.
I. Chemical Recycling: Pyrolysis Reshapes Plastic’s Lifecycle
Pyrolysis heats plastics to 400–600°C in oxygen-free environments, fracturing polymer chains into small molecules. It overcomes mechanical recycling’s material limits, processing low-value waste like: Medical plastics, Ocean debris, and Mixed packaging.
Core Value of Plastic Pyrolysis:
1. Resource Circularity: Converts waste into: Liquid pyrolysis oil, Solid fuel, and Non-condensable fuel gas.
2. Economic Boost: Pyrolysis oil serves as fuel or chemical feedstock.
Hydrogenation purification significantly increases its value.
3. Carbon Reduction:
Slashes CO₂ emissions vs. incineration.
When oil is produced from recycled plastic, it cuts 2.3 tons of CO₂ per ton beyond virgin plastic savings (Science of the Total Environment).
II. Global Benchmark: Industrializing Chemical Recycling
Niutech’s technology operates commercially worldwide:
Denmark’s Circular Model: 20,000-ton/year plant directly supplies pyrolysis oil to BASF, converting it into recycled plastic monomers—closing the “waste-to-new-plastic” loop.
Medical Waste Valorization: Henan project treats HW01-category hazardous medical waste. Oxygen-free pyrolysis destroys pathogens while yielding high-value oil.
7 International Certifications: the EU CE, German TÜV, ATEX, ISCC, etc. Equipment exported to the USA, Germany, Denmark, and more.
Broader Impact: Plastic recycling isn’t just environmental cleanup—it’s resource reuse and economic value creation.
Scaling recycling in China (60 million tons/year) could replace 100–150 million tons of crude oil.
Global adoption could solve “white pollution” and grant plastics eternal rebirth.
