It`s expected that biogas power generation by methane fermentation will spread for the purpose of utilizing renewable energy. The biochemical methane potential (BMP) is used as the main indicator for assessing the potential to produce methane of a substrate. Resent studies have reported that components in biomass correlated to methane production. The aim of this study was to investigate the influence of chemical components of food waste on the BMP with a special focus on acid detergent fiber (ADF; indicates lignin and cellulose) and lipid with a high theoretical methane potential. Using the variables, poor regression models was found for food waste. The correlation between lipid and BMP was found, with R2 of 0.73. The best BMP prediction equation (R2 =0.90) was obtained as a result of two-variable regression analyse when ADF and lipids were used as independent variable. The BMP prediction equation is applicable to only a specific food waste, but easy-to-use.
