Abstract
Anaerobic digestion (AD) is a sustainable ways in managing the fruit and vegetables waste (FVW) as due to its suitable properties. However, study of AD on these waste are less reported in Malaysia. FVW was characterized and used as substrate for biochemical methane potential (BMP) test. A batch BMP test using Automatic Methane Potential Test System (AMPTS II), was carried out under mesophilic temperature. The result showed that FVW contained complex organic compounds in particulate and soluble forms. The organic compounds were existed mostly in form of particulate matter, indicates by lower concentration of soluble form. Overall, the anaerobic process of FVW was stable throughout the study and completed in a shorter period. Results shows that the AD of FVW reveals ultimate methane yield of 294ml CH4/g VS. In addition, the kinetics parameter observed from modified Gompertz modelling analysis was fitted well to the laboratory data.
