In a groundbreaking study published in ‘Discover Materials’, researchers have unveiled a method to optimize the yield of carbon black derived from waste tyre pyrolysis, a process that could significantly impact the construction sector. Lead author Odunayo T. Ore from the Department of Chemistry at Kogi State University has spearheaded this research, which emphasizes the commercial viability of recycling waste materials into high-value products.
The study meticulously examined key parameters—feedstock mass, residence time, and temperature—to maximize carbon black yield. With an impressive R² value of 0.99, the findings demonstrate not only the accuracy of the model but also the potential for large-scale application. “Our analysis shows that feedstock mass plays a pivotal role in determining the yield of carbon black,” Ore stated, highlighting the study’s emphasis on precision in process optimization.
The optimal conditions identified—40 grams of feedstock mass, a temperature of 350 °C, and a residence time of 60 minutes—resulted in a carbon black yield of 25.25 wt.%. This yield closely aligns with experimental results, underscoring the reliability of the response surface methodology used in the study. The implications for the construction industry are substantial, as carbon black is a critical component in producing rubber and composite materials used in various applications, including tires, coatings, and even concrete additives.
Characterization of the carbon black produced revealed a compact structure with minimal porosity, enhancing its thermal stability and resilience against environmental degradation. These attributes make it particularly suitable for long-term applications, which is vital for construction materials that demand durability and reliability. “This research lays the groundwork for further exploration into optimizing the pyrolysis process, suggesting that various conditions can lead to even more efficient production methods,” Ore added.
As the construction industry increasingly seeks sustainable materials, the ability to convert waste tyres into valuable carbon black could revolutionize material sourcing and reduce environmental impact. By turning waste into a resource, this research not only contributes to sustainability efforts but also opens new avenues for economic growth within the sector.
The study’s findings are a testament to the potential of innovative recycling methods in addressing environmental challenges while satisfying industry demands. For further insights into this research, you can visit the Department of Chemistry at Kogi State University.
