Rising global energy demands necessitate cleaner, more sustainable sources. Biogas produced through anaerobic digestion, offers a renewable solution for household fuel, vehicle systems, and electricity generation applications. However, raw biogas contains impurities that must be removed to enhance its quality calorific value. This paper comprehensively reviews upgrading including cryogenic separation, membrane technology, adsorption, scrubbing, focusing on their economic viability problem-solving potential. Among these, chemical scrubbing is highlighted high efficiency, excellent mass-transfer efficiencies, reasonable setup operation costs, making it the most frequently employed technique producing high-purity methane. study underscores importance of selecting appropriate technologies improve utility sustainability.

The increasing concern over greenhouse gas emissions, particularly CO2, has emphasized the urgency for practical solutions to mitigate environmental impacts of climate change. This study assessed technical, economic, and feasibility producing dimethyl carbonate (DMC) through an integrated route using methanol derived from biomass gasification in sugarcane-based industries. Unlike previous studies that analyzed isolated aspects DMC production, this research was conducted process modeling simulation Aspen Plus® V12.1, evaluating key performance indicators such as conversion rates, product purity, capital operating expenses, CO2 emissions. A rate 78.06% a purity level 96.80% were achieved. However, integration production increased both CAPEX OPEX, leading net present value (NPV) R$ 36.7 million 10 years, lower than alternative routes commercially available methanol. Additionally, resulted emission 3.41 kg per DMC, exceeding conventional methods. These findings suggest under evaluated conditions, did not offer economic advantages, despite many advantages
