12 PRAJ Technology Advantage Reduced water consumption in distillery (~60%) Improved GHG reduction compared with Molasses-C Up to 2-3% over all plant power reduction in sugar factory. Multi-feed option in distillery depending on feedstock availability Multi-product option depending on market scenario Solution to cyclic sugar cane production cycle. Additional 30% extra production with marginal or no Capex in existing plant Praj Industries Ltd
