Acidogenic fermentation (AF) of wastes provides a biological route to volatile fatty acids (VFA) production as an alternative fossil hydrocarbons. As VFA are acidic in nature, the pH AF typically drops, affecting performance. The effect different alkaline substances such urea, NaOH, or CaCO3 on organic residual solids (ORS), food waste-rich fraction municipal solid waste (MSW), was studied. Enzymes were used additive simultaneous hydrolysis and (SHF) experiments. Use urea (66 mg Urea g−1 TS) SHF resulted yield 0.14 g VS after 6 days, 177% higher than control (no addition). ammonia concentrations significantly influenced bacterial population distribution. In using NaOH/CaCO3, added alkalinity 11 L−1 did not influence yields with NaOH addition at 7 higher. This study demonstrates that, while increasing up 8.5 improves production, is detrimental due enzyme inhibition. Finally, use source must be considered carefully naturally reached by can inhibit hydrolysis.
