     this study was carried out to assess the impact of organic loading rate (olr) on the performance of mesophilic anaerobic baffled reactor (abr) for h2 production from a co-digestion of municipal food waste and kitchen wastewater. the reactor was operated at different organic loading rates (olrs) of 29, 36 and 47 g codtotal/l d. the hydraulic retention time (hrt) was kept constant at 1.6 d. the results showed that increasing the olr from 29 to 36 g codtotal/l d, leads to a significant (p □ 0.01) drop in the h2production from 6.0 ± 0.5 to 5.4 ± 1.04 l h2/d, respectively. however, the h2 production remained at the same level of 5.3 ± 1.04 l h2/d at increasing the olr from 36 to 47 g codtotal/l d. the h2 generation was mainly due to conversion of cod (57%) and carbohydrate (81%). protein and lipids conversion represents only 23.3% and 4.1% respectively for h2 production.
