Chemical and allied industries in India are poised for higher growth in the coming decade. Due to stringent environmental regulations, the market for technologies related to treatment of industrial waste and its utilization is expected to grow further. Appropriate technologies, specifically the ones that recover value added products, shall find market without much difficulty. A sustainable hybrid waste/wastewater treatment methodology, capable of removing multiple pollutants along with renewable energy generation is another area that has immense potential. Conventional treatment processes often fail due to varied characteristics of the waste water. Anaerobic dark fermentation treatment produces methane, which is again a greenhouse gas. Hence, a novel approach has been made to produce hydrogen using pre-treated mixed culture. An effort also has been made to produce bio-plastic and bio-electric from the anaerobically treated waste water. By integrating these process steps COD, BOD and TDS could be reduced to acceptable limits besides producing energy by these dual approach. More details will be presented during the talk.
