With the increasing awareness of environmental protection and the emphasis on resource recycling, the treatment of waste tires has become an important challenge in global environmental protection and resource management. In order to meet these challenges, a waste recycling company in Nigeria sought a reliable, efficient and scalable waste tire treatment solution. Through cooperation with Beston Group, the company successfully implemented pyrolysis treatment technology to convert waste tires into high value-added resources.
1. Background & Challenges
A Nigerian waste‑recovery company faced large stockpiles of end‑of‑life tires. These tires resist natural breakdown and occupy scarce land. Moreover, they pose severe fire risks and attract disease vectors. Traditional disposal methods such as landfilling and open burning release toxic fumes. Consequently, local communities suffer air and soil pollution. Therefore, the client urgently needed a scalable, turnkey solution. It had to process at least 4,000 tonnes per year. Furthermore, it needed to produce valuable outputs and ensure environmental compliance.
2. Actions & Solution
According to the needs of Nigerian customers, Beston technical team provides BLJ-16 tyre pyrolysis plant, the configuration includes:
- Manifold+Catalytic Tower: Dual system is for future treatment of plastic/oil sludge, which increases the richness of raw material processing.
- Hydraulic Feeding:PLC‑controlled hydraulic ram ensures continuous, safe tire loading, reduces manual handling, and minimizes downtime.
- Vertical Condensation: This condensation effectively improves oil-gas separation efficiency and ensures oil product quality.
3. Achieved Results
After the pyrolysis equipment was debugged and the operators were trained, the system ran smoothly and achieved the recycling goals:
- Pyrolysis oil: The oil yield of a single batch operation reached about 40%. The oil quality meets the local boiler fuel requirements.
- Carbon black: Produces about 30% tire pyrolysis carbon black by weight, which is suitable for the rubber and coating industries. It can also be refined into rCB.
- Steel wire: Separate and recycle the steel wire in waste tires to achieve near-zero solid waste emissions.
4. Future Outlook
Building on this success, the customers plans to expand its operations. Next steps include plastic and oily‑sludge pyrolysis. Moreover, they will activate the catalytic tower upgrade. In addition, they will test new catalysts for higher gas yields. Furthermore, they will install a modular heat‑recovery unit. Therefore, energy consumption will decrease significantly. Ultimately, expanded products will include syngas for power, refined oils for chemical feedstocks, and engineered carbon materials. Consequently, the project will boost regional circular economy goals. It will also create new revenue streams. Finally, it will serve as a model for sustainable waste valorization in West Africa.
