Hydrogen production from the organic fraction of municipal solid waste in anaerobic thermophilic acidogenesis: Influence of organic loading rate and microbial content of the solid waste

► We studied the hydrogen production from municipal solid waste. ► Different operating conditions were assayed in this study. ► Increasing organic loading rates resulted in an increase in hydrogen production. ► It is possible to treat solid waste within an optimal range for a liquid substrate. ► Microbial concentration in the reactor is influenced by the microbial content of the waste.
