“…The worm-gut phosphatases and P-solubilizing microbes present in worm casts cause organic waste P mineralization in vermicomposting system. The results of P-mineralization are corroborated by the findings of earlier workers who have observed waste quality dependent mineralization rate in waste mixtures during vermicomposting process (Aira et al, 2006;Gomez-Brandon et al, 2011). The tot Ca content in vermicomposted material ranged from 137.4± 0.25 (T 1 ) to 156.5 ± 0.12 mg kg −1 (T 3 ) that indicates the high mineralization of wastes during vermicomposting process.…”

“…The maximum growth rate was observed in T 5 and T 1 followed by T 4 , T 3 and T 2 . The feed quality (proportion of easily metabolizable organic matter, non-assimilated carbohydrates and microbial richness) directly or indirectly affects the earthworm growth in waste feedstock in vermicomposting system (Flegel and Schreder, 2000;Gomez-Brandon et al, 2011;. Results clearly suggest the suitability of Silver Oak leaf litter as a better feedstuff for earthworms.…”

“…The traditional methods of disposal such as open dumping and land filling practices of industrial wastes are not only expensive, but also environmentally unsafe [3]. The biodegradation of industrial waste prior to its use could reduce the pollution associated with its management [1,4,5]. Vermicomposting by earthworms is a bio oxidative process which is considered as one of the alternative options for converting wastes into nutrient rich vermicompost useful for plants and the soil [6,7].…”

Aims and Objectives:The present study was conducted to utilize the Milk Processing Industry Sludge (MPIS) for the purpose of vermicomposting, in two sets of experimentsviz. with earthworms (ME) and without earthworms (MW).Methods and Materials:Twenty young non-clitellatedEisenia fetidawere released in each tray. The various parameters like growth, clitellum development, biomass, cocoon production and hatchlings ofE. fetidawere observed after every 15 days, during 90 days of vermicomposting.Results:The maximum growth and better responses were observed in ME25mixtures of MPIS which was the minimum ratio of the waste to CD. The physico-chemical analysis (pH, EC, TKN, TOC, C/N ratio, TAP, TK, TNa) and heavy metals (Cr, Cu, Mn, Pb) were also done before and after vermicomposting process. There was a significant increase in TKN (23-46%), and TAP (39-47%), and a decrease in pH (6.2-6.8%), EC (24.6-37.2%), TOC (16.8-37.9%), C/N ratio (23.8-97.9%), TK (26.6-40.6%), and TNa (31.3-53%) and heavy metals (Cr 30.9-40.6%, Cu 32.7-44.6%, Mn 23.9-36.3%, and Pb 32.6-42.9%) from initial to final feed mixtures with earthworms.Conclusion:Thus the final vermicompost had excellent physico-chemical properties with all nutrients in plant available forms. The study further strengthens that the vermicomposting is an efficient technique in converting MPIS into nutrient rich biomanure in a short period of timei.e. 90 days.

“…Although microorganisms participate in decomposition of organic matter, earthworms act as a critical driver of this process by comminuting the organic matter, increasing the area of aerobic microbial activity and triggering the enzymatic activity, thus stimulating the decomposition further 2) . FVWs such as mushroom wastes 3) , pineapple wastes 4) , tomato wastes 5) , grape marc 6) and vegetable mixture [7][8][9] are considered to be important nutrient sources and can be treated by this technology. Since the compositions of FVWs are complex and vary depending on the lifestyle and eating habits of consumers, to determine and elevate the efficiency of vermicomposting for FVWs and clarify the mechanisms involved, systematical and intensive investigations are desired.…”

“…Conventional vermicomposting requires a preliminary treatment to dry fresh FVWs for one to three weeks [3][4][5][6][7][8][9] because earthworms cannot survive in the feed materials with high-content of water. This not only increases the whole time needed for vermicomposting but also requires energy.…”

The aim of this study was to evaluate the feasibility of rapid vermicomposting of different fresh fruit and vegetable wastes (FVWs) including banana peels, cabbage, lettuce, potato and watermelon peels using earthworm Eisenia foetida. For this, the changes of physicochemical properties, microbial profiles and earthworm biology were comprehensively evaluated after vermicomposting for 4 weeks. Compared to controls (without earthworms), vermicomposting caused reductions of the total carbon content by 42.7-52.4% and the carbon to nitrogen ratios by 46.5-61.1%, and increases of the electrical conductivity by 6.7-69.4% and the total phosphorous content by 4.0-52.0%. Vermicomposting revealed a higher microbial activity, density and diversity in end products than controls. The vermicomposting treatment for FVWs allowed a high growth rate of earthworms and an increased number of cocoons. Similar microbial community structures were observed in all vermicomposts, indicating a high degree of bio-stabilization and maturity. The results suggest that rapid vermicomposting is a feasible technology for converting fresh FVWs into valuable products and that the quality of vermicomposts is strongly associated with the properties of initial substrates.
