India produces huge volume of organic waste annually. This waste comes from agriculture, urban and industrial sources and also from domestic activities. Utilization of this waste material for productivity process is important for both economical and environmental reasons. In the present study an attempt was made to convert the biodegradable green wastes into value added compost using an exotic earthworm, Lumbricus rubellus. The experiments were carried out in a plastic tray at 50% concentrations of green waste for a period of 60 days. Chemical analysis of worked substrates indicated step-wise increase of nitrogen and phosphorus. The increase of phosphorus and nitrogen were found to be high for green waste undergoing vermicomposting. During the composting period the organic carbon decreased from its initial value 7.12% to 5.09%. The results indicate that 50% concentration of waste mixed with bedding material was ideal for the vermicomposting.
