Aimed at delivering reliable investment references for global partners, Beston Group performed dedicated pyrolysis testing on diverse tire samples in 2025. Beyond monitoring oil yields, we systematically gathered data on carbon black recovery rates. All testing followed standardized laboratory procedures to ensure that every metric provides a scientific foundation for our clients’ equipment configuration and financial forecasting.
Methodology during Tests
- Subject each tyre sample to controlled tyre pyrolysis conditions.
- Record the time, flue gas temperature, oil and carbon black production changes for each sample.
- Measure the weight and yield of the pyrolysis products to assess product efficiency.
Conclusion from Tests
Test results indicate:
- Tire oil yield: 37%-45%
- Carbon black yield: 36%-44%
Please note that actual yields vary depending on tire types (e.g., passenger car tires vs. OTR tires).To determine the precise recovery rates for your materials, please reach out to schedule a dedicated lab test.
