STUDY ON POTENTIAL OF BIOGAS PRODUCTION FROM ANAEROBIC DIGESTION OF FOOD WASTE IN HANOI

Abstract

Anaerobic digestion of food waste is an important approaching method for waste reduction, energy
recovery, and fertilizer production. This paper forcused on study on potention of biogas recovery from
anaerobic digestion of glocery moring and mustard under different experimental conditions of
temperature, pH, and methane producing bacteria. Experimental results show that, volume of biogas
from anaerobic digestion of glocery morning in 19 days was about 80 mL biogas/g VS under conditions
of temperature of 37oC, pH of = 7 ~ 8 and methane producing bacteria. The volume of biogas
production in this case was higher from 1.6 ~ 2 times in comparision with that of biogas production
under experimental conditions of room temperature, without pH stabilizing, or without added methane
producing bacteria. Volume of biogas production in the case of green carbage was about 224 mL
biogas/g VS under anaerobic digestion time of 60 days. This intial experimental results showed the
biogas recovery potential from anaerobic digestion of vergestabe waste under the suitable experimental
conditions and the posiblility in application for other types of food waste.
