Abstract
Extraction of the organic content from vegetable market waste and tea waste was carried out in a packed digester for 24 and 300 h respectively. The sequence of appearance of volatile fatty acids during digestion of both the substrates was found to be different. The sequence was (Acetic, Propionic) > (Isobutyric, Butyric) > Valeric for digestion of vegetable market waste while it was Isovaleric > (Isobutyric, Acetic) > Propionic during digestion of tea waste. During the course of digestion, the early appearance of an acid did not relate to its high concentration. The rate of production of acetic acid and propionic acid was found to be higher than other volatile acids during digestion of both the substrates, although it was approximately ten times higher for vegetable market waste compared to tea waste. The acids can be arranged in four groups according to their rate of production as Acetic > Propionic > Butyric > (Valeric, Isobutyric) for vegetable market waste and Acetic > Isobutyric > Isovaleric > Propionic for tea waste.
