Abstract
India and many other developing countries are suffering from the disposal of solid wastes due to urbanization and population density. Saw dust is a waste product of timber industries, produced by wood working machinery, portable power tools or by use of hand tools. In some manufacturing industries, it can be a significant fire hazard and source of dust pollution. It is composed of fine particles of wood and is the main component of particleboard. Research on saw dust health hazards comes within the field of occupational health science, and study of saw dust control comes within the field of indoor air quality engineering. Vermicomposting is a simple biotechnological process of composting, in which earthworms are used to enhance the process of waste conversion into useful end product. In this study, the role of earthworm in converting the saw dust into a valuable product is assessed. The saw dust was mixed with cow dung and earthworm Eudrilus 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 methods. The reduction in pH and organic carbon were noticed at 30-day. The result indicated that vermicomposting with Eudrilus eugeniae is better for converting saw dust into nutrient rich vermicasting in a short period of time. Thus, the recycling of wastes through vermitechnology reduces the problem of accumulation of timber industry wastes. Vermicompost slowly releases N, K, Ca, Mg and P to plants.
