      <Abstract>The production of high-purity Bio-CNG from biogas is a critical step in transitioning to sustainable, renewable energy sources. Biogas, primarily composed of methane and carbon dioxide, requires effective upgradation to remove impurities such as CO?, hydrogen sulfide (H?S), and moisture to meet the quality standards of Bio-CNG. Traditional upgradation methods, including water scrubbing, pressure swing adsorption (PSA), and chemical absorption, have limitations in terms of efficiency and scalability. Recent advancements, such as membrane separation, cryogenic techniques, and hybrid systems, offer promising solutions to enhance methane concentration and reduce energy consumption. This research reviews the latest biogas upgradation technologies, focusing on their technical feasibility, energy efficiency, and economic viability. By exploring these cutting-edge techniques, the study aims to identify the most effective approaches for achieving high-purity Bio-CNG production that can support the growing demand for cleaner energy alternatives and contribute to global carbon reduction efforts.</Abstract>
