Poultry-processing industries generate substantial quantities of waste, posing significant environmental challenges due to the complexity of handling and disposal. This study explores an innovative solution that combines thermochemical treatment of poultry waste with furrow-diking technology to transform non-recyclable feathers and bones into biochar—a nutrient-rich soil amendment. The research identifies optimal pyrolysis conditions for biochar production and evaluates its effects on soil moisture retention, compaction reduction, and erosion control. Experimental trials on sloped terrains reveal that incorporating biochar into compartmentalized furrows enhances water-holding capacity and soil structure, providing a sustainable approach to addressing agricultural challenges. Pyrolyzing poultry waste at 500 °C produced biochar with high nitrogen content and stability, capable of retaining up to 90% of its mass in water and significantly reducing soil compaction. Furthermore, applying 10 metric tons of biochar per hectare can sequester 5–8 metric tons of carbon annually, contributing to long-term carbon mitigation and regenerative agriculture. This integrated methodology combines waste valorization with ecological restoration, unlocking new opportunities for scalable and sustainable soil-management solutions. [ABSTRACT FROM AUTHOR] |
