Scrap Tire Pyrolysis
Thermal conversion of scrap tires into recoverable material and energy streams.
Tire pyrolysis is one pathway within the broader Harborview recycling platform. It must be paired with feedstock control, emissions review, product upgrading, carbon black purification, market qualification, and authority support.
Typical output streams
- Pyrolysis oil
- Syngas
- Recovered steel
- Pyrolytic carbon black
- Heat and internal process energy potential
Commercial reality
- Outputs must meet buyer specifications.
- pCB usually requires upgrading to become higher-value rCB.
- Environmental controls must be project-specific.
- Permits and community acceptance are critical.
- Offtake letters should be secured before financing.
Project development sequence
1. Tire Supply
Secure tire sources, monthly volumes, hauling costs, disposal economics, and generator commitments.
2. Technology Match
Select pyrolysis, shredding, rCB, or asphalt route based on local economics and permits.
3. Product Buyers
Develop offtake for oil, gas, steel, rCB, crumb rubber, and other recovered materials.
4. Authority Support
Obtain LOIs, grant support, public works input, and environmental compliance review.
