In the recent times, the industrial pollution has emerged as a major threat to water resources around the world, particularly in the Global South (developing countries) where a scenario prevails that the pollution is a price to pay for progress (Greenpeace, 2011). This view is generally associated with numerous thoughts that the dealing with pollution is too costly, pollution prevention is too difficult and impractical; and that environmental and social impacts can be dealt with in the future. In contrast, the case studies from the Global North (developed countries) have exposed the extent to which persistent and bio-accumulative substances that had contaminated the regions till date, show the immense difficulties and a very high expense of restoration programmes and the impossibility of total decontamination (Greenpeace, 2011). The paper industries are the sixth biggest noxious waste producing industries of the world. Paper manufacturing is an agro-based industry. The fast growth in population and the higher demand for industrial establishment to meet human necessity have produced evils such as overexploitation of obtainable resources and pollution of the land, air and water (Kumar et al., 2017a, b). The effluent generated is characterised by dark colour, foul odor and high organic content and extreme quantities of chemical oxygen demand (COD), biochemical oxygen demand (BOD) and pH (Pokhrel et al., 2004). The dark colour in paper mill effluent is caused due to the presence of organic ligands such as wood extractives, resins, products (Deilek et al., 2001). Industrialization has become an important factor to the development of a country’s economy, through the establishment of plants and factories However, the waste or by-products discharged from them are severely disastrous to the environment consists various kind of contaminant which contaminate the surface water, ground water and soil (Kumar et al., 2016; Kumar and Thakur, 2017). The application of microbial or plant biomass could be an effective, low cost and ecofriendly means for removal and/or recovery of toxic metals from contaminated wastewater and industrial effluents, even at low concentrations.
