The process of composting had been studied using six different types of blends, each simulating different Carbon- Nitrogen (C/N) ratio for the formation of compost. The raw material was a mixture of bio degradable waste (University Mess), bulking agent (saw dust) and cow dung as compost accelerator Six composting bins each of 100 Lcapacity were installed with holes at various depth for probes and leachate collection system. The bins (length 50 cm, width 40 cm, height 50 cm) were placed horizontally with a slight inclination to permit the collection of leachate. The evaluation studies included the operational indices such as temperature, pH, moisture content, compost maturity indices like C/N ratio, elements, bulk density and microbial survival. Blowers of this system were useful in maintaining aerobic condition (aeration at a rate of 2.3 m3/min) in the entire compost bay. Further germination studies were performed to ascertain the compost quality. The final compost having C/N ratio around 20 was satisfactory for its agricultural application based on the results.
