Abstract
The enhancement of biogas production, specifically methane enrichment is critical for
improving the efficiency and viability of biogas as a renewable energy source. This report
examines the role of activated carbon in increasing methane yield and the quantity of
biogas produced in a digester at NALIRRI by the Direct interspecies electron transfer
Process (DIET). Activated carbon known for its high surface area, electrical conductivity
and porosity provides a conducive environment for the adsorption of inhibitory compounds
and the DIET process. Furthermore, it facilitates a more stable and enhanced microbial
activity leading to increased biodegradation and methane production. Experimental setups
incorporating various concentrations of activated carbon were monitored and analyzed.
Parameters like pH, temperature and organic loading rate were monitored alongside the
addition of activated carbon to maximize methane output. The results indicate a
significant increase in methane production with the addition of activated carbon and it can
contribute to the development of a cost-effective and sustainable method to increase the
quantity of biogas produced in a bio-digester hence a promising approach to enhance biogas
production with implications for renewable energy and waste management practices. This
report concludes with recommendations for further research and application of biogas on
systems.
