## China’s Chemical Recycling Policy: Pilot Projects, Regulatory Framework, and Commercial Scale-Up Under the 15th FYP
Chemical recycling receives unprecedented policy support under China’s 15th FYP, with targets of 2 million tonnes annual capacity by 2030.
### Policy Support
**National Strategy**:
– Chemical recycling as complementary to mechanical
– Technology neutrality principle
– Pilot project approval fast-track
– Carbon credit eligibility
**Regulatory Framework**:
– Environmental impact assessment guidelines
– Product quality standards for pyrolysis oil
– Safety regulations for chemical processes
– Waste import restrictions (domestic feedstock focus)
### Pilot Projects
**Sinopec (Beijing)**:
– Technology: Pyrolysis
– Capacity: 100,000 tonnes/year

### Economic Analysis
**Capital Costs**:
– Small scale (10,000 t/y): ¥100-200 million
– Medium scale (50,000 t/y): ¥300-500 million
– Large scale (100,000+ t/y): ¥500-1,000 million
**Operating Costs**:
– Feedstock: ¥1,000-3,000/tonne
– Energy: ¥500-1,000/tonne
– Labor and maintenance: ¥300-500/tonne
– Total: ¥2,000-4,500/tonne
**Revenue**:
– Pyrolysis oil: ¥3,000-5,000/tonne
– Chemical products: ¥5,000-10,000/tonne
– Carbon credits: ¥50-100/tonne
**Profitability**:
– Break-even: ¥2,500-3,500/tonne
– Margin: 10-30% at scale
### Challenges
**Technical**:
