Abstract

Food waste landfilling causes environmental degradation, and this work assesses a sustainable food valorization technique. In this study, food waste is converted into lactic acid in a batch assembly by dark fermentation without pH control and without the addition of external inoculum at 37°C. The effect of total solid (TS), enzymatic, and aeration pretreatment was investigated on liquid product concentration and product yield. The maximum possible TS content was 34% of enzymatic pretreated waste and showed the highest lactic acid concentration of 52 g/L, with a lactic acid selectivity of 0.6 glactic/gtotalacids. The results indicated that aeration pretreatment does not significantly improve product concentration or yield. Non-pretreated waste in a 29% TS system showed a lactic acid concentration of 31 g/L. The results showed that enzymatic pretreated waste at TS of 34% results in the highest production of lactic acid.
