Kurzbeschreibung (Abstract)
The purpose of this investigation is to study the effect of 1) leachate recirculation (LR) and dilution (LD), 2) the increment of the waste ratio, and 3) co-digestion using poultry waste as co-substrate for enhancing the acidogenesis process of the organic municipal solid waste (OMSW), thereby increasing the medium chain fatty acids (MCFAs) production. The results of the experiment carried in a batch pilot reactor show that LR increases hydrolysis as well as the OMSW conversion efficiency. Meanwhile, the highest total MCFA production of around 62,000 mg/L is shown for LR with a high OMSW ratio. Thus, a high concentration of hexanoic acid is shown in LR lysimeters (5475 mg/L, 6627 mg/L, and 10,889 mg/L respectively). However, a metabolic shift toward the production of heptanoic and octanoic acids is reported for LD samples. Nonetheless, the use of poultry waste as co-substrate in the co-digestion process multiplied the concentration of the produced MCFAs.
