Acidogenic fermentation of vegetable based market waste to harness biohydrogen with simultaneous stabilization
چکیده انگلیسی

Vegetable based market waste was evaluated as a fermentable substrate for hydrogen (H2) production with simultaneous stabilization by dark-fermentation process using selectively enriched acidogenic mixed consortia under acidophilic microenvironment. Experiments were performed at different substrate/organic loading conditions in concurrence with two types of feed compositions (with and without pulp). Study depicted the feasibility of H2 production from vegetable waste stabilization process. H2 production was found to be dependent on the concentration of the substrate and composition. Higher H2 production and substrate degradation were observed in experiments performed without pulp (23.96 mmol/day (30.0 kg COD/m3); 13.96 mol/kg CODR (4.8 kg COD/m3)) than with pulp (22.46 mmol/day (32.0 kg COD/m3); 12.24 mol/kg CODR (4.4 kg COD/m3)). Generation of higher concentrations of acetic acid and butyric acid was observed in experiments performed without pulp. Data enveloping analysis (DEA) was employed to study the combined process efficiency of system by integrating H2 production and substrate degradation.
