Praj is one of the few companies in the world to successfully develop and demonstrate second generation ethanol production using agri-residue. Dr. Mahesh stressed on the various factors which necessitate the need for sustainability such as growing volatility in the feedstock and ethanol prices, Rising energy and water cost, stringent pollution control norms and uncertainty in government policies. Sustainability requires reduced effluent generation at the source itself, recycle and reuse of water and integration of effluent treatment systems with the main process plant.
