Assessment of Cocoon Production of Eudrilus eugeniae through Bioconversion of Distillery Solid Waste with Elephant Dung

The dumping of organic wastes from the distillery industries leads serious threats to environment. The organic wastes disposal cause unpleasant odour, soil pollution, and distribution of vector borne diseases in human beings and highly infectious viral diseases which affects different animals. Bioconversion of distillery solid waste with elephant dung has been renowned and efficient technology used for reducing pollutants, making noble fertilizer and maintaining pollution free environment. The present study aimed at the bioconversion of distillery sludge combined with elephant dung using earthworm Eudrilus eugeniae Lin. and assessment the cocoon production. The three treatment combinations (T1-SD, T2- ED and T3-SED) were selected and introduced the earthworm E. eugeniae for bioconversion. The physico-chemical characteristics were subjected for the initial day and final day (60 days).The results showed that the values of pH, electrical conductivity, total nitrogen, total phosphorus, total potassium, total calcium and total magnesium were increased with a declining trend of total organic carbon and C/N ratio from its initial value. From the results it was inferred that the organic wastes were effectively converted into a nutrient loaded vermicompost. The cocoon production of E. eugeniae was observed in all the treatments at different time intervals (0, 15, 30, 45 and 60 days) were the higher level of cocoon production in SED combinations 114+38 to 152±9.2.Vermi- bioconversion is a appropriate method of using worms to transform organic waste into a nutrient-rich fertilizer, a healthy and a soil remediation from the pollution.
