Abstract

Agro-industrial wastes- wastes from agriculture, food processing or any cellulose based industries- remain largely unutilized and often cause environmental problems like dispersing foul odors, occupying vast areas, ground and surface water pollution etc. These wastes could be converted into potential renewable source of energy, if managed sustainably and scientifically. In the last few decades, vermicomposting technology has been arising as a sustainable tool for the efficient utilization of the agro-industrial processing wastes and to convert them into value added products for land restoration practices. The product of the process, i.e., vermicompost is humus like, finely granulated and friable material which can be used as a fertilizer to reintegrate the organic matter to the agricultural soils. The usability of the process depends upon several factors like raw material, various process conditions- pH, temperature, moisture, aeration etc., type of vermicomposting system and earthworm species used. The chapter briefly discusses with the process technology of vermicomposting and the present state of research in the vermicomposting of agro-industrial processing wastes.
