Core Advantages of Pyrolysis Treatment

As a resourceful and volume-reducing solid waste treatment technology, pyrolysis offers significant advantages over traditional methods like incineration and landfilling in terms of resource recovery, environmental benefits, and application scenarios. The key strengths are as follows:

1. Efficient Resource Recovery, Turning Waste into Value

It can simultaneously produce high-value products such as fuel oil, carbon black, and combustible gas from raw materials like waste tires, plastics, and biomass, enabling circular resource utilization.

For example, fuel oil from waste tire pyrolysis can replace fossil fuels, carbon black can be used in rubber production, and the generated gas can be recycled as an on-site energy source, significantly increasing the economic value of solid waste.

2. Significant Volume Reduction, Lowering Disposal Pressure

Pyrolysis reduces solid waste volume by 60%–80% and weight by 50%–70%, drastically decreasing the amount of waste sent to landfills or incinerators and easing the pressure on landfill capacity.

It is particularly suitable for handling non-biodegradable wastes like waste tires and plastics, avoiding long-term pollution to soil and groundwater from stockpiling.

3. Controllable Emissions, Lower Pollution Risks

Conducted in an oxygen-deficient environment, pyrolysis avoids the direct release of large amounts of NOₓ and SO₂ that occur in incineration. With supporting exhaust purification systems, it can efficiently treat pollutants such as HCl, VOCs, and dioxins, making it easier to meet environmental standards.

Unlike incineration, it does not produce hazardous fly ash, and residues (e.g., carbon black) can be recycled, further reducing environmental burdens.

4. Strong Energy Self-Sufficiency, Lower Operational Costs

Combustible gas generated during pyrolysis can be recycled to heat the furnace, achieving energy self-sufficiency, reducing reliance on external energy sources, and lowering project operating costs.

Some large-scale projects can achieve over 80% energy self-sufficiency through energy recycling, further enhancing economic viability.

5. Wide Application Scenarios, Adaptable to Multiple Waste Types

It is applicable not only to waste tires and plastics but also to biomass, oil sludge, and hazardous waste, meeting the solid waste disposal needs of various industries.

The process is flexible: by adjusting parameters like temperature and pressure, product composition can be optimized to meet diverse market demands.
