Abstract: India is the largest producer and consumer of sugar in the world. Among the several industries, sugar industry is the most important industry. Bagasse is the name for the residual fibers that remain after the squeezing of sugarcanes at the sugar production. Usually, they consist of 40 – 60% cellulose, 20 – 30% hemicellulose, and about 20% lignin. Vermicomposting is a simple biotechnological process of composting, in which earthworms are used for recycling of organic waste into ecofriendly end product. In this study, the role of earthworm in converting sugarcane bagasse into a valuable product is assessed. The sugarcane bagasse was mixed with cow dung and earthworm Eudrillus eugeniae and left for vermicomposting for 30 days. After 30 days, the vermicompost was collected and the physico-chemical parameters were analyzed by using the standard protocols. Organic carbon and the pH were reduced dramatically at 30-day of vermicomposting. Eudrillus eugeniae is found to be the best candidate, for converting sugarcane bagasse into nutrient rich vermicasting in a short period of time (30-day). Thus, the recycling of wastes through vermitechnology reduces the problem of accumulation of sugar industry wastes effectively. Vermicastings are found to be rich in nutrients like N, K, Ca, Mg and P.
