- Abstract
The utilization of the municipal solid waste (MSW) through conversion via vermicomposting practice was performed with the on-site system operation, using the earthworm Eudrilus eginiae. Here, various co-substrates were investigated for the vermicomposting practice. They were dry cow dung (CD), kitchen waste(KW), sewage sludge(SS) and vegetable-market waste(VW), respectively. The seven different mixture ratios of MSW were investigated in this study; CD as single control (Tr1), CD:KW in 20:80 (Tr2), CD:SS in 20:80 (Tr3), CD:VW in 20:80 (Tr4), CD:KW:SS:VW in 25:25:25:25 (Tr5), CD:KW:VW in 20:40:40 (Tr6), and CD:KW:SS in 20:40:40 (Tr7). Chemical changes of these MSW at different mixture ratios during vermicomposting were analyzed. The C/N ratio of 10.4+0.5 was the most suitable value. Moreover, the number of total earthworm (NTE), the number of adult earthworm (NAE) and Number of cocoon per total weight of earthworm (NoC) also showed highest value as 33,854 ew/m³, 3,255 ew/m³ and 0.22 cocoon/g-TWE, respectively. From overall results, Tr3 and Tr7 appears to be the ideal mixture ratios for enhancing maximum biopotential of earthworms for MSW management as well as for earthworm biomass and vermicompost production.
