Biochemical Methane Production Potential of Soluble Leachate from Biological Solid State Fermentation with Batch Jar Tests

Biochemical methane potential (BMP) was evaluated for biogas production with different substrate and different seeding sources. Biological solid state fermentation (SSF) on organic waste was done in our Lab. With the purpose to evaluate an efficiency of SSF biodegradation processes about jar tests of farm waste and biological pretreatment of Napier grass mixed kitchen waste. In this study, a soluble leachate from aerobic SSF processes and a liquid substrate from biodegradation farm waste (anaerobic SSF) were investigated for biogas production. A difference of COD concentration and seeding sources were conducted. Our results revealed that, with a substrate from kitchen waste achieved highest CH4 production. Efficiency of biodegradation was demonstrated by biogas production rate, removal efficiency of chemical oxygen demand (COD). It was found that the highest soluble COD removal was 86%. In the experimental studies, two different seeding sources were used and compared through biogas fermentation.
