Modern day life is much dependent on fossil fuel which has various environment constraints and its resource is also limited. Hydrogen is an important renewable and sustainable energy source with high energy value and no adverse effect on environment. Different carbohydrate rich waste materials have been used for bio-hydrogen production by dark fermentation process using anaerobic bacteria. In this context, integration of ceramic catalytic membrane in membrane bioreactor can be an attractive option to enhance the production of bio-hydrogen. The present study is focused on design of an innovative fermentative bioreactor process for bio-hydrogen production by dark fermentation process utilizing molasses waste and anaerobic bacteria Clostridium sp. (MTCC 11078). Dark fermentation experiment for bio-hydrogen production was carried out in 7 L bioreactor in batch mode initially with synthetic molasses having initial pH 7 and glucose conc. 5g/L at 450C with continuous stirring at 300 rpm for 7 days. Initial result showed that after 48 h of fermentation process bio-hydrogen production was started and highest production (0.2 mol H2/mol of carbohydrate) was achieved after 120 h and COD of synthetic molasses was decreased by 25%. The ceramic based catalytic membranes indigenously prepared on clay-alumina support would be used in future for treatment of molasses wastewater with catalytic activity to increase the rate of bio-hydrogen production. Overall, the present study proposes a novel ceramic catalytic membrane based bioreactor process that integrates wastewater treatment and catalysis functions to enhance bio-hydrogen production from industrial waste. This innovation has the potential to address the existing challenges in bio-hydrogen production and significant improvement in the efficiency, providing a sustainable and efficient solution for renewable energy applications.
