Wet waste recycling at generation point will alleviate burden on the overflowing waste dumpsites in developing nations. Drum composting is a potential treatment option for such waste at individual or community level. The present study was aimed to produce compost from wet waste (primarily comprising food waste) in composting drums modified for improved natural air circulation. Effect of microbial inoculum and waste turning on composting process was also studied. The final results showed the production of matured and stable compost in the modified drums. Addition of the microbial inoculum resulted in thermophilic phase within a week time. The self-heating test and germination index (>80%) showed the production of non-phytotoxic and mature compost in the modified drums after 60days. The change in microbial population, humic substances and biological parameters (lignin, cellulose and hemicellulose) during the study is discussed. Moreover, the reduction in waste mass and volume is also reported.
源头湿垃圾回收可减轻发展中国家垃圾填埋场超负荷运转的压力。堆肥是在个人或社区层面处理此类垃圾的一种潜在处理选择。本研究旨在通过改良的堆肥桶从湿垃圾（主要包括食物垃圾）中生产堆肥，以改善自然空气流通。还研究了微生物接种物和废物翻堆对堆肥过程的影响。最终结果表明，改良桶中可生产成熟稳定的堆肥。添加微生物接种物可在一周内进入高温期。在 60 天后，自热试验和发芽指数（>80%）表明改良桶中可生产无植物毒性且成熟的堆肥。研究中还讨论了微生物种群、腐殖质和生物参数（木质素、纤维素和半纤维素）的变化。此外，还报告了废物质量和体积的减少。
