Abstract:
Press mud, a waste byproduct from sugar mill operations, is often dumped in open pits causing many environmental problems. A design was developed for biogas extraction using the following feedstock: press mud from a sugar factory, cow dung readily available from farms, and a combination of press mud and cow dung. The chemical composition and characteristics of the feedstocks were analyzed to determine carbon and nitrogen contents, moisture, percent volatile solids, and other properties. Three units of biogas equipment were constructed using a floating collection pail design to generate methane gas by biodigestion. Experiments were conducted to determine the impacts of parameters such as C:N ratio and pH. The results showed that when water and press mud was mixed with cow dung at a ratio of 1: 0.148 : 0.15, corresponding to a C:N ratio of 24, the daily biogas yield compared to press mud alone increased from 3.5 to 25 cubic meters per day, equivalent to a 614 percent increase. The gas flame characteristics from the press mud and cow dung experiment corresponded to a flame temperature of around 1900 degrees C, appropriate for use in a gas stove.
