Apple pomace and vegetable waste (radish leaves, cauliflower leaves' and stalk and rotten cabbage) were subjected independently and also in succession to anaerobic digestion inoculated with cattle dung, on a laboratory scale. Each kilogram (dry weight) of apple pomace fed could generate 275 1 of biogas (57% Cttu), fresh vegetable waste generated 210 l ofbiogas (72% CH4) and rotten cabbage led to the generation of 5'20 l of biogas (68% CH4). Adaptation of methanogens to changing feed material was also observed.
This study was on municipal vegetable market waste, where the nature of the material changes with the season. As these materials do not carry any methanogens, the possibility of developing a bacterial culture which could adjust itself to regularly changing feed material was investigated. The biomethanation in two different reactor setups which were fed initially with fruit waste up to 113 and 122 days followed by vegetable wastes for 60 and 30 days, respectively, is reported. We also report here the direct biomethanation of vegetable wastes under different culture conditions in two separate set-ups.
