PRODUCTION OF BIOGAS VIA ANAEROBIC DIGESTION OF FOOD AND PLANT WASTES

Biogas is a clean energy that can substitute or reduce the usage of
liquid petroleum gas (LPG) and natural gas. However, the
availability of feedstock used for the production is a major
downside. In this study, a small-scale unit of biogas was produced
from food (vegetable and fruit wastes) and plant wastes via
anaerobic digestion (AD) reaction process. The reaction
parameters used in this study were the reaction condition and
retention time. The experiment was conducted for 14 days to test
the influence of reaction parameters towards the yield of biogas.
From the study, it was observed that the yield of biogas was higher
in a light AD condition (0.7470 ml/g) compared to the dark
condition (0.025 ml/g). Furthermore, as the retention time
increases, the yield of biogas also increases slightly. In addition,
the finding affirms the possibility of biogas production using a
mixture of food and plant wastes with further study is needed for
the parameter’s ranges used in the study
