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.

Index Terms—Methane production, organic waste, thermophilic digestion, wastewater sludge.
