Biogas production using waste water: Methodologies and applications

Biogas is competitive, viable, and generally a sustainable energy resource due to abundant supply of cheap feedstock's and availability of a wide range of biogas applications in heating, power generation, fuel, and raw materials for further processing and production of sustainable chemicals including hydrogen, and carbon dioxide and biofuels. Biogas can also be used in fuel cells for direct conversion to electricity and raw material for hydrogen and transport fuel production which is a significant pathway to sustainable energy development. Enriched biogas or biomethane can be containerized or injected to gas supply mains for use as renewable natural gas. Biogas digesters provide an opportunity for integrated waste management systems that combine waste treatment, energy generation, and resource recovery. By integrating biogas digesters into waste management infrastructure, it becomes possible to create closed-loop systems that maximize the potential of organic waste while minimizing environmental impacts. This holistic approach promotes sustainable practices, reduces reliance on conventional waste treatment methods, and creates a more circular and resource-efficient economy.
