“…1). The reduction of EC values can be considered due to the addition of WCS and uptake of the minerals by earthworms (Singh and Kaur, 2015). The added waste carbide sludge (WCS) is containing 30-40% lime concentration.…”

“…However, these processes are quite expensive and none are considered to be commercially viable (Gutierrez et al, 2006) and still the problem remains unsolved, since lignin undergoes a spatial rather than chemical change and thus persists albeit in a different form (Singh and Kaur, 2015). Primary concerns include the use of chlorine-based bleaches and resultant toxic emission to air, water and soil with global annual growth forecast at 2-5%, the industry and its negative impacts could double by 2025 (Gutierrez et al, 2006;Wang et al, 2011).…”

Presently, 50-60 m 3 of water needed to produce a ton of paper and around 240-250 chemicals have been identified in effluents, which are produced at different stages of paper making in pulp and paper industry. The pulp and paper industry is typically associated with pollution problems related to high BOD, COD, toxicity, AOX, color, suspended solids, lignin and its derivatives and chlorinated compounds. Although numerous studies have looked ways by various researchers to remove COD, BOD, color etc. of pulp and paper effluents, the problem still persists. Number of microorganisms including bacteria, fungi and actinomycetes has been implicated to degrade the xenobiotic compounds present in pulp and paper mill effluent. This article review the origins and effects of major pollutants present in pulp and paper mill effluents and the progress made in their reduction through fungi, bacteria, algae and enzymes as well as further scope is also discussed.

“…Vermiprocesses are emerging techniques used for composting [18][19][20][21][22] and wastewater treatment [23,24]. They have also been studied for the treatment of some industrial effluents such as beverage, distillery or paper mill wastewater [25,26]. These processes are based on the ability of earthworms (Eisenia fetida) to convert organic matter into compost (called vermicompost or vermicast) by transit through their gut.…”

For potential use in air treatment by biofiltration, a new material composed of vermicompost and earthworms (Eisenia fetida) was tested for the removal of a volatile organic compound (VOC), toluene. The removal rate of toluene was measured during batch experiments in presence of vermicompost only, earthworms only and a mixture of both. In the chosen experimental conditions, no mortality of earthworms was recorded and the results showed that the presence of earthworms allowed an increase in toluene removal rate (0.213 mg.h -1 ) compared to vermicompost only (0.084 mg.h -1) and earthworms only (0.136 mg.h -1 ). From the experimental data, mechanisms of toluene transfer and adsorption/biodegradation by microorganisms from vermicompost and/or earthworms were proposed.
