The Indian Pharmaceutical Industry :: Environment, Toxic Waste Affluents

The Indian pharmaceutical industry has fast growing at the rate of 14 percent per year [Indian brand equality foundation, 2009] and its ranks is very high in the third world, in terms of technology, quality and range of medicines manufactured. A rapid expansion and sophistication of chemical and pharmaceutical industries has increased the amount and complexity of toxic waste effluents. The effective removal of substances included in pharmaceutical effluents is a challenging task due to the wide variety of Chemicals produced biological products ,medicinal chemicals , botanical products in drug manufacturing plants such as analgesic, antibiotics, antidepressants, antidiabetics, contracepes, growth regulators, drugs, painkillers, and tranuilizers (Robinson et al., 2007; Ghauch et al., 2009) which lead to wastewaters of variable compositions into natural systems and consequent degradation of the environment (Mehta, G at al.1995). The effluent generated from these industries is typi cally toxics, colored, organic and turbid with high suspended solids. This in turn has led to an increase in various kinds of diseases. For example many organic compounds that are recalcitrant in nature are produced while manufacturing pharmaceutical products, while most of them that are poorly degradable are released in effluent. And sometimes formation of N-nitrosamines, a possible carcinogen in stomach another issue of ecological concern is causing of algal blooms or eutrophication in water bodies (Chih-Hsiang Liao et al., 2003). The pharmaceutical effluents were treated by traditional techniques such as ï ¬â€šocculation, coagulation, conventional biological treatment, ï ¬ ltration, reverse osmosis, precipitation ,incineration, and triple effect evaporator because of high TDS. In these approaches, the pollutants are transferred from a liquid phase to a solid phase (Takaoka et al., 2007), and also facing corrosion problems. A biological treatment is highly effective for the re moval of most contaminants, however biodegradation processes are inherently slow and do not allow for high degrees of removal. The sludge formed during biological treatment has to be disposed either by land filling or burning, which increases considerably the running costs. In addition, sludge disposal may pose further environmental problems.( Noelia Barrabes et al., 2011) In this sense, catalytic process appears as the most promising technology. Current pharmaceutical industry were practicing triple effect evaporate for treatment of high dissolved solids, in these route high amount of sludge is generated and also high amount of steam required. Now a day the researchers are mainly focus on the eco-friendly and economically viable technologies are much desirable in these days.
