Abstract

Urban domestic solid waste in India contains 75-85 % organic substances. The uncontrolled dumping of this waste is a significant health concern. To solve this issue, degradation of organic waste by using microbial consortium is safe, efficient, and economical. Therefore, this study is done to recycle the domestic, green solid waste into active compost using a microbial consortium. Antagonism assay is used to develop Bacterial consortia, thereby determining the concomitant enzyme production. A suitable consortium is further used to degrade 2 kg of organic solid waste producing compost. Analysis of the compost, showed: C-22.1%, N-0.78%, K-0.62ppm, P-0.51ppm, and S-0.24ppm. The proposed consortia had the highest decomposing capability compared to other consortia. Compost so produced, was reduced to 86% in mass, dark colored, with grainy texture lacking foul smell. It was observed that the C: N::21:1;and increased percentage of K, P, S, thereby contributing to enhance soil fertility. The bacterial consortium so prepared serves as a vital tool in removing organic solid waste from environment. Further the compost produced can be used to increase fertility of soil.
