Title : Multiple strategies for carbon capture and its utilization from biogas generated by anaerobic digestion in wastewater treatment sectors
Abstract:
It is contradictory to efforts to achieve net zero carbon emissions by 2050 since the wastewater treatment sectors’ energy consumption is leading to a rise in global power consumption and contributing to greenhouse gas emissions. Bacteria in the anaerobic digestor (AD) in wastewater treatment plant decompose organic solid waste and create biogas consisting of approximately 60% methane and 40% carbon dioxide. The biogas that is being produced currently has been let off into the atmosphere. Once carbon capture and utilization (CCU) technology implemented next to an AD plant, it is feasible to simultaneously reduce greenhouse gas emissions and boost profitability. This is performed by turning carbon dioxide into products that have a commercial value, such as concrete construction materials, as well as alternative energy sources derived from biomethane, such as syn gas, fuel cells etc. There are a handful distinct tactics that carbon may be captured, and it all depends on how biogas is utilized. This research demonstrates various techniques for disintegrating biomethane and carbon dioxide from biogas, as well as various strategies for carbon capture from biomethane during pre- and post-combustion, and effective utilization in the production of alternative fuel sources that can be reused to generate electricity and reduce reliance on conventional fossil fuels. This work also provides an overview of the efficient usage of carbon dioxide in a variety of industries, including the wastewater treatment facility. Therefore, effective integration of CCU with AD plant reduces the consumption of conventional fuels, which in turn raises the level of sustainability and helps minimize emissions of greenhouse gases into the atmosphere.
