Abstract :

The rapid increase in the volume of waste is one of the aspects of the environmental crisis, accompanying recent global development. India produces around 3000 million tons of organic waste annually. This huge volume of waste(s) comes from various activities including domestic. Management of solid waste has become one of the biggest problems we are facing today. Most common practices of waste processing are uncontrolled dumping which causes mainly water and soil pollution. Besides dumping or sanitary land filling, the final disposal of solid waste can be carried out by other methods like incineration and composting. Utilization of this waste material for productivity process is important for both economical and environmental reasons. In the present study an effort has been made to check the efficacy of E. foetida (red tiger worm) in vermicomposting. Vermicomposting is a bio-conversion process which is widely being used for solid waste management. The vermicompost and vermiwash produced were rich in nitrogen, phosphorous and potassium (NPK). The vermicomposting improves the soil structure, enhancing soil fertility, moisture holding capacity and in term increase the crop yield. It becomes an important tool of waste recycling the world over.
