Advantages of Pyrolysis Oil Refining Technology for Treating Rubber-Based Solid Wastes

Pyrolysis technology is a mainstream resource recycling solution for rubber-based solid wastes (especially waste tires). Compared with traditional methods such as landfilling and incineration, it has the following core advantages:

1. Efficient Resource Recovery, Turning Waste into Valuable Products

Rubber-based solid wastes can be converted into fuel oil (≈40%), carbon black (≈30%), steel wire (≈15%), and combustible gas (≈15%) through pyrolysis, with all products having commercial value.

Fuel oil can be directly used as industrial boiler fuel or further refined into diesel; carbon black can be applied in tire recycling and plastic production; steel wire can be recycled for steelmaking, achieving 100% resource utilization.

2. Significant Environmental Benefits, Avoiding Secondary Pollution

The entire process is carried out in an oxygen-free or low-oxygen environment, eliminating the release of highly toxic pollutants such as dioxins and sulfur oxides from incineration. Exhaust gas can meet emission standards after purification treatment.

It eliminates the need for landfilling, solving the problems of long-term land occupation, soil pollution, and groundwater contamination caused by leachate from rubber waste.

3. Flexible Processing Scale, Adapting to Different Scenarios

Equipment can be scaled from small batch-type units to large industrial production lines with daily processing capacities of dozens of tons, meeting the needs of waste disposal projects of various sizes.

It has strong raw material adaptability, capable of processing various rubber products such as conveyor belts and hoses in addition to waste tires, without requiring complex sorting.

4. Stable Economic Returns with Clear Commercial Value

The products have stable market demand: fuel oil and carbon black are essential industrial products with relatively stable price fluctuations, ensuring strong project profitability.

In some regions, projects can benefit from environmental subsidies and tax incentives, further enhancing economic viability.

5. Mature and Reliable Technology with Controllable Operational Risks

Multiple processes, including batch-type and continuous-type systems, have been commercially applied, with high equipment automation and simple operation and maintenance.

Supporting technologies such as exhaust gas purification and oil refining are increasingly sophisticated, effectively controlling pollutant emissions and ensuring oil quality compliance with environmental and industrial policies.
