Abstract
The need for an environmentally friendly energy source in the world has led to major diversification in renewable energy. Biogas provides a renewable energy source that will replace fossil fuel inevitably. The experiment was carried out using a self-designed laboratory-scale anaerobic biogas digester. The study was carried out at room temperature from 25 - 31°C for 20 days using corn stalk as the main substrate while Pig manure and eggshell were used as co-substrates. The findings showed that the biogas produced from the sample containing a blend of corn stalk, Pig manure, and eggshell resulted in higher biogas volume than the sample containing corn stalk and eggshell, corn stalk, and pig manure as well as the sample containing only corn stalk. This implies that the use of the corn stalk blend is a source of renewable energy. Thus, ensuring the sustainability of biogas production in the future.
