Abstract
The suitability of biomass system depends on products recovery from the waste. Switchgrass was the most renewable biomass sources and selected as feedstock for the volatile fatty acid production from anaerobic digestion. The five kinds of pretreatments involving physical and chemical treatment such as thermal, hot water, acid, alkaline and organosolv pretreatment were investigated. This study explored the characteristics of Volatile Fatty Acid (VFA) production from pretreated switchgrass compared with raw biomass. The major VFA compounds are acetic acid, propionic acid, butyric acid, iso-butyric acid and iso-valeric acid and hexanoic acid produced during digestion. The result showed that acetic acid concentration yields higher with other compounds of VFA.
