Abstract

Pilot-scale experiments were conducted to study the anaerobic composting of food waste mixed with hay, and organic commingled waste mixed with septage. Location of this study was the Suranaree Military Camp in Nakhon Ratchsima City in northeastern Thailand. Hay was mixed with the food waste in a 1/0.34 ratio by volume (1/4.54 ratio by weight), and septage was mixed with the organic commingled waste in a 1/7.06 ratio by Volume (1/1.58 ratio by weight). Out of a total of four composting runs, the first run was carried out for 90 days, and the other three for 100 days each. Initial C/N ratio was kept at 25-30/1. Maximum temperature during the anaerobic composting process in the four runs ranged between 52-603C and was achieved within three days from the start-up time. C/N ratio of the end product ranged between 13.9-18.5. A total coliform bacteria kill was achieved in the range of 99.81-99.99%.
