Vegetable wastes have high carbohydrate and high moisture
content and thus are a good substrate for the production of
biogas through biomethanation process. Several researchers
have studied biogas production from mixture of vegetable
waste. Biogas yield reported by researchers is in the range of
0.360 L/g of VS to 0.9 L/g VS added. The temperature, pH and
organic loading rates have a pronounced effect of vegetable
waste biomethanation. The reactors of different designs also
influence on the biogas yield. The use of appropriate catalysts is
found to increase the biogas yield from anaerobic digestion of
vegetable waste. Biomethanation process also reduces the load
of organic pollutants in terms of reduction of TS, VS, BOD and
COD. Thus, biomethanation appears to be an eco-friendly
technology for the treatment of vegetable waste
