China’s Chemical Recycling Policy: Pilot Projects, Regulatory Framework, and Commercial Scale-Up Under the 15th FYP

## 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
– Feedstock: Mixed plastic waste
– Status: Under construction

**Brightmark Energy (Zhejiang)**:
– Technology: Plastics renewal
– Capacity: 50,000 tonnes/year
– Feedstock: Film and flexible packaging
– Status: Operational

**Carbios (Joint Venture)**:
– Technology: Enzymatic PET recycling
– Capacity: 10,000 tonnes/year (pilot)
– Feedstock: Colored and complex PET
– Status: Demonstration phase

**Eastman Chemical (Jiangsu)**:
– Technology: Polyester renewal
– Capacity: 50,000 tonnes/year
– Feedstock: Mixed polyester waste
– Status: Engineering phase

### Technology Pathways

**Pyrolysis**:
– Temperature: 400-600°C

### 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**:
– Feedstock quality consistency
– Product quality standardization
– Catalyst development
– Energy efficiency improvement

**Economic**:
– High capital requirements
– Feedstock competition
– Product market development
– Subsidy dependence

**Regulatory**:
– Emission standards
– Safety requirements
– Product certification
– Waste classification
