Optimizing Composting And Soil Fertility: A Sustainable Waste Management Strategy

Abstract

Effective biodegradable waste management is a cornerstone of sustainable urban and peri-urban living. To strengthen this capability at the source, this study emphasizes a strategic modification of conventional pipe composting into a perforated pipe design, aimed at enhancing aeration, accelerating decomposition, and promoting localized nutrient cycling. With enhanced aeration and direct soil contact, the method significantly accelerates the breakdown of organic matter. A comparative longitudinal study over two composting cycles demonstrated that perforated systems achieved up to 92.9% volume reduction within six weeks—nearly three times faster than conventional pipe compost. Additionally, proximity-based nutrient uptake was observed in Lantana camara plants, indicating potential for integrated soil enrichment. The system’s simplicity, low maintenance, and adaptability to household and small-scale agricultural contexts make it a viable solution for sustainable urban and peri-urban waste treatment. These findings highlight the dual advantages of perforated pipe composting—efficient biodegradation and localized nutrient cycling—providing a scalable pathway toward sustainable waste management.
