Selection of Convenient Organic Matters for Bioenergy Generation: A Comparative Approach

This paper focuses on selecting the most convenient bioenergy production from four different organic matters: cow dung, food waste, flower waste, and fruit waste. The co-digestion process is used to produce biogas from wastes. Waste decomposes quickly after co-digestion and attains higher methane percentages in a specific time. This paper determines the ability to produce bioenergy considering the attained methane percentage from each waste slurry. A floating drum plant-type portable biogas plant is used in the research work to produce biogas from each waste slurry. A portable biogas analyzer machine is used to measure the percentage of produced methane, carbon dioxide (CO
2
), oxygen (O
2
), and hydrogen sulfide (H2S). The result shows that the highest percentage of methane (65.3%) is obtained from food waste slurry within 20 days, whereas cow dung gets the methane percentage as 54%. The calorific value of food waste and cow dung for producing biogas is 333.57 kWh/m
³
and 275.4 kWh/m
³
, respectively that indicates the food waste as the most convenient source of bioenergy generation than others.
