Abstract

Solid waste management is a huge challenge all over the world. Despite the availability of various methods of waste disposal, enormous problems like soil deterioration, toxic effect and increased pollution on land, air, water and living beings are being encountered. Hence the objective of the study is an eco-friendly one stroke solution for waste disposal, which manages the waste and gives some beneficial end product in addition. A newfangled method of Vermitechnology is considered as an important tool of waste recycling. In this study, efforts were made to scrutinize suitability of the Sewage Sludge , Dairy Sludge, and the mix of these Sludges to Vermicomposting and the potential of epigeic earthworm Eisenia foetida to transform the sludges, spiked with Farmyard Manure to value added product, i.e., vermicompost. During the period of study, physcio-chemical characteristics like pH, EC, Organic matter, organic carbon, nitrogen, phosphorous and potassium were analyzed periodically. Pre decomposition of 15 days and subsequent vermicomposting of 21 days resulted in significant increase in nutrients, weight loss and a decrease was found in pH, Organic matter and Organic Carbon. Earthworm size and reproductive performance, in terms of number of worms were also higher during this period.
