Abstract
Waste generation by society is increasing, alongside a growing demand for fuels and other commodity chemicals which rely on fossil resources, that contribute significantly to global warming and air pollution. Organic residual streams, like wastewater sludge, which contains 30% to 70% of amino acids, have great potential to be an alternative for that. The anaerobic digestion of these streams produces volatile fatty acids (VFAs), that can be utilized to produce chemicals, such as bioplastics and biofuels. Microorganisms can produce VFAs under certain range of pHs. This study showed that when pH was dropped to 5.5 VFAs production was twice as higher as when the pH was uncontrolled.
