Although the high fat content can improve the gas production potential of food waste, it can also have an inhibitory effect during the process of anaerobic digestion. Methanol concentration is too high, methanogenic bacteria susceptible to oil and long-chain fatty acids, thereby inhibiting the hydrolysis of food waste, affecting gas production.
