“…The pre-composting because of its thermophilic nature prior to vermicomposting helped in mass reduction and pathogen reduction [27]. It was found that the bulk (dry) mass reduction and stabilization of both the wastes during present study through vermicomposting process were significant [2,27]; the vermicomposting may also be known as vermistabilization [28]. The cow dung used as the inoculant in the vermicomposting process enhanced the quality of feeding resource attracting the earthworms and accelerated the breakdown of wastes resulting in the reduction of C : N ratio by increasing certain nutrients [1,[29][30][31].…”

Major nutrient status of vermicompost of vegetable market waste (MW) and floral waste (FW) processed by three species of earthworms namely,Eudrilus eugeniae, Eisenia fetida, andPerionyx excavatusand its simple compost were assessed across different periods in relation to their respective initiative substrates. Their physical parameters—temperature, moisture, pH, and electrical conductivity—were also recorded. The nutrients—nitrogen, phosphorus, potassium, calcium, and magnesium—increased in the vermicompost and compost while the organic carbon, C/N and C/P ratios decreased as the composting process progressed from 0 to 15, 30, 45, and 60 days. The nutrient statuses of vermicomposts of all earthworm species produced from both the wastes were more than that of the compost and that of their respective substrates. Moreover, the vermicompost produced byE. eugeniaepossessed higher nutrient contents than that ofE. fetida, P. excavatus, and compost. The MW showed higher nutrient contents than the FW. Thus, vermicomposting is the paramount approach of nutrient recovery of urban green waste.

“…This process also results in an excessive increase in the number of earthworms. These earthworms can be used for animal protein supplementation and as a fish bait, but they are always considered as a byproduct of the vermicomposting process, while their castings that enrich vermicompost always remains the principal product (Wang et al, 2007 ).…”

Improved agricultural practices and rapid industrialization have led to huge waste generation, and the management of this waste is becoming a global concern. The process of vermicomposting has emerged as a method of choice for converting waste into useful manure, with evidence of increase in crop productivity. During vermicomposting, the collective activities of decomposing microorganisms and earthworms lead to the humification of organic/inorganic waste, thereby generating the final product called vermicompost. Different types of industrial wastes such as waste from paper industries, tanneries, sugar mills, and pulp and textile industries have been effectively converted to vermicompost and successfully used to improve plant growth. The vermicompost thus formed was also demonstrated to increase the production of pharmaceutically important plant secondary metabolites such as withanolides and polyunsaturated fatty acids. Microbial amendment with different bacterial and fungal strains during vermicomposting further proves to be beneficial by increasing nitrogen content, decomposing organic waste, providing aeration, and stabilizing the vermicompost. These microorganisms after passing through the earthworm's intestine increase in numbers in the vermicast, thus becoming enriched in vermicompost, which is particularly important for their use as biofertilizers. The precise role of different microbial pretreatments in improving the quality of vermicompost generated from industrial and agricultural waste is, however, not completely understood. To fill this gap in knowledge, the present article aims to review published literature to highlight the potential of microbial amendment during vermicomposting for bioremediation of industrial and agricultural waste. Microbial pre-composting followed by vermicomposting emerges as an ecofriendly and economical approach for managing agricultural and industrial waste.

“…Increasing appearance of microorganisms in drinking water or wastewater has raised concerns about systemic effects on human health. Water disinfection is still a scientific and technical challenge since conventional methods used to supply drinking water such as chlorination and ozonation have shown disadvantages related to the formation of potentially hazardous disinfection byproducts (DBPs) [1] . Consequently, specific disinfection steps need to be included in the treatment chains by considering the water quality objectives in terms of technical reliability, economic and environmental criteria [2] .…”

Nanometer photo catalytic-membrane reactor integrated photo catalytic technology with membrane separation technology was applied to remove virus existing in water. Bacteriophage f2 was used as surrogates for human enteric viruses. Two kinds of nanomaterials (TiO2and ZnO) were selected as the catalyst. Three kinds of membranes interception performance for virus, adsorption efficiency of nanomaterial for virus, inactivated effect for virus with photo catalysis, and the comprehensive effect to f2 of photo catalytic-membrane reactor were studied under the transmembrane pressure of 20Kpa, with nanomaterial concentration of 100mg/L, light dose of 20mJ/cm2. It showed that the interception effect of flat membrane with casting was the best. the adsorption efficiency of the two kinds of nanomaterials was different, 1.478 lg and 0.201 lg for TiO2and ZnO, respectively. The removal effect of the photo catalytic oxidation system to f2 was similar, both in 2-3 log. The removal efficiency of the photo catalytic-membrane reactor system has no obvious difference, both in 3-4 log, and it is improved significantly compared to the effect of individual photo catalysis and membrane separation. Further research indicates that: the elimination function of coupling system to f2 includes UV-inactivated, adsorption of nanomaterials, the inactivation of nanomaterials, the effect of oxide moiety which formed after nanomaterials absorbing ultraviolet light and membrane retention.
