“…Varma et al . investigated the feasibility of utilizing vermicomposting on waste carbide sludge which was collected from an acetylene gas production plant in India . Waste carbide sludge in various proportions was mixed with vegetable waste, cow dung, and sawdust in a ratio of 5:4:1 by using dried leaves as bulking materials.…”

Currently, industrial sludge is generated in large amounts. Industrial sludge is a solid or semi‐solid material consisting of all compounds removed from wastewater, as well as any substances added to the biological and chemical operation units during the treatment process. The composition of sludge may vary considerably. Furthermore, distinctive treatment and disposal methods are necessary as sludge produced from different industries has different characteristics. Therefore, processing and disposing of industrial sludge is a challenging and complex environmental problem. Landfilling, incineration and agricultural land application are the three most commonly employed methods for the disposal of industrial sludge. Among the three methods, the agricultural land application is a convenient and economical disposal alternative for industrial sludge. However, industrial sludge could have high putrescible content and pathogenic hazards. One possible way to ensure that the industrial sludge could be reused on agricultural land is by conditioning and stabilizing the sludge using a pretreatment process. One of the pretreatment processes which could be employed in this context is vermicomposting. Vermicomposting is an alternative for biological stabilization of organic wastes, with the addition of earthworms. Through vermicomposting, industrial sludge could be transformed into matured organic fertilizer or vermicompost in a shorter period. Thus, this work reviewed the recent literature on utilizing the vermicomposting process to manage industrial sludge in order to assess the feasibility of this technology. The present review also provides a brief overview of the production and treatment methods of industrial sludge. © 2017 Society of Chemical Industry

“…Several epigeics (Eisenia fetida, Eisenia andrei, Eudrilus eugeniae, Perionyx excavatus and Perionyx sansibaricus) have been identified as potential candidates to decompose organic waste materials (Suthar, 2007;Varma and Kalamdhad, 2015). Some attempts have been made to biodegrade a variety of materials using vermicomposting (Sangwan et al, 2007).…”

“…Elvira et al (1998) have reported the increase of Zn, Fe, Mn and Ni concentration in the vermicompost of paper-pulp mill sludge. Similarly, Varma et al (2015) have reported increase in heavy metal concentration of waste carbide sludge (WCS) and agricultural waste after vermicomposting.…”

“…This increase in TKN content may be due to the discharge of mucus, nitrogenous substances, hormones, enzymes etc. by the worms (Tripathi and Bhardwaj 2004;Varma et al 2015). Hartenstein and Hartenstein (1981) have reported that pH also plays an important role in retention of TKN by the vermicomposts as at higher pH it may be lost as ammonia.…”

Purpose Parthenium hysterophorus is one among the most troublesome weeds at the global level. It is mainly controlled by chemical methods. The scientific community is in search of new but non-destructive approaches for its management. Vermicomposting is one among the promising technologies for the management of organic fraction of solid wastes. This study was undertaken to assess the vermicomposting of parthenium weed mixed with biogas plant slurry under laboratory conditions. Method Six different combinations of biogas plant slurry and parthenium were fed to worms in vermibins under controlled laboratory conditions for 60 days. Various physico-chemical parameters before and after vermicomposting were evaluated. Worm biomass production was also monitored periodically during the experimentation period. Results The EC, TCa and NPK content increased significantly after vermicomposting, accompanied by substantial reduction in organic carbon content. C: N ratio was reduced to less than 20. Heavy metals (Fe, Zn, Ni, Cu, Cr and Pb) concentration was higher in vermicompost than in initial waste mixtures. Parthenium weed addition to worm feed was not supportive to the worm growth and fecundity.It was inferred from the results that vermicomposting may be an efficient biological approach to convert partheniumspiked biogas plant slurry into nutrient-rich manure.
