Sustainable biogas: An attempt at blending tradition and innovation for green energy through co-digestion of cow dung and elephant grass
Year: 2025
Type: article
Abstract: Biogas, a product of anaerobic digestion, presents a promising avenue for renewable energy production, offering a sustainable alternative to traditional non-renewable energy sources. This study explores the potential of biogas production through the co-digestion of cow dung and elephant grass, employing a locally fabricated mild steel biodigester. Through comprehensive physiochemical analysis the moisture content (cow dung–49.64%, elephant grass–74.1%), fiber content (cow dung–6.4%, elephant grass–7.12%), nitrogen content (cow dung–2.03%, elephant grass–0.68%), protein content (cow dung–12.69%, elephant grass–4.26%), fat content (cow dung–5.81%, elephant grass–6.89%), and ash content (cow dung–19.72%, elephant grass–0.73%) were ascertained. They affirmed the suitability of the substrates to ensure effective bio digestion, laying a solid foundation for further exploration. Despite meticulous adherence to standard procedures, biogas production failed to meet expectations, revealing inherent limitations within traditional biogas generation methodologies. This underscores and reiterates the urgent need for a more professionalized approach to biogas production, that integrates advanced technologies and expertise to optimize yields. Beyond mere production metrics, the study underscores broader socio-economic and environmental implications, emphasizing the critical importance of addressing inefficiencies to advance sustainability and resilience within local communities. By transcending traditional paradigms, stakeholders can unlock the full potential of biogas as a renewable energy resource, fostering greater accessibility and contributing to a more sustainable energy future.
