Effect of Organic Waste Source on Methane Production during Thermophilic Digestion Process
Rafik M. Hesnawi and Ruqua A. Mohamed
Abstract—This work was conducted to determine the
production of methane from different organic waste substrates.
Laboratory-scale reactors (5.0 L) operated at 55°C was used.
Three different types of organic wastes were used: residential
food waste, chicken manure, and secondary sludge from
wastewater treatment plant. After 90 days of thermophilic
digestion, it was found that the methane content range from 57
to 97.05%. The highest production of methane was obtained
with municipal wastewater sludge while the lowest production
was obtained with food waste. It was also found that methane
production was affected by the ratio of waste to water (w/v).
Wastes dilution ratio of 1:2 showed comparatively higher
methane content than the wastes dilution ratio of 1:1.
