Requirements for Annual Processing Capacity of Tire Pyrolysis Oil Refining

Requirements for Annual Processing Capacity of Tire Pyrolysis Oil Refining

The annual processing capacity requirements for tire pyrolysis oil refining projects are mainly governed by national industrial policies, environmental protection standards, and local access conditions, as detailed below:

1. National Policy Requirements

Industrial Structure Adjustment Guidance Catalog: Encourages large-scale, intensive tire pyrolysis projects, typically requiring an annual processing capacity of no less than 10,000 tons of waste tires. In some regions, this threshold is raised to 20,000 tons to avoid environmental risks and resource waste from small-scale projects.

Environmental Compliance Threshold: The Ministry of Ecology and Environment imposes strict restrictions on small, scattered pyrolysis projects. Those with an annual processing capacity of less than 10,000 tons usually struggle to pass environmental impact assessments, as they must demonstrate robust waste gas, wastewater, and residue treatment capabilities.

2. Regional Variations in Local Access Conditions

Eastern Coastal Areas: Economically developed regions such as Shandong and Jiangsu generally set higher capacity requirements, often ≥20,000 tons/year. Some industrial parks even mandate ≥30,000 tons/year to enable centralized management and control.

Central and Western Regions: Access thresholds are more flexible, aligned with local industrial foundations, but most provinces still require ≥10,000 tons/year to ensure sufficient environmental investment and technical standards.

3. Technical and Economic Matching Requirements

Projects with an annual capacity of less than 10,000 tons face higher unit-capacity environmental costs and operational expenses, making stable profitability difficult. Large-scale projects (≥20,000 tons/year) can reduce costs and improve economic efficiency through equipment integration and energy recycling.

Mainstream commercial equipment is typically designed for capacities of 10,000–50,000 tons/year, with 20,000–30,000 tons/year being the most balanced in terms of technical maturity and investment payback period.
