This study investigated the effects of polyurethane foam on continuous hydrogen production from mixed wastes. Molasses was co-fermented with non-pretreated sewage sludge in a sequencing batch reactor. The results indicated that the addition of polyurethane foams as a microbial carrier in the reactor mitigated biomass loss at HRT 12 h, while most of the biomass was washed out during the operation period with no carrier. There was a stable hydrogen production rate of 0.4L?H©� /l/d in the carrier-sequencing batch reactor. Suspended biomass in the carrier-reactor indicated it possessed the highest specific hydrogen production rate ( 241¡¾4ml?H©� /gVSS/d ) when compared to that of biomass on the surface ( 133¡¾10ml?H ©�/gVSS/d ) or inner carrier ( 95¡¾14ml?H©�/gVSS/d ).
