N2 - The utilization of the recycling of biomass waste for carbon dioxide (CO2) adsorption in biogas is still rare. Even though the experiments on the biogas purification still using synthetic biogas. This paper investigated the recycling of biomass waste, sugarcane bagasse for biogas purification. The conversion of biomass into biochar was claimed to expand the surface area of its pores for capturing CO2 in biogas. Five treatments of adsorbents used in this study, 100% volume of zeolite or biochar, 75% volume of zeolite and 25% biochar, 50% volume of zeolite and biochar, 25% volume of zeolite and 25% volume of zeolite, and 25% volume of biochar. The difference of volume treatment in adsorbents affected methane (CH4) and CO2 composition of biogas. Biogas purification by adsorption was conducted at 5-7 bar pressure range and room temperature. Biogas before and after purification were tested of CH4 and CO2 composition by gas chromatography. A significant reduction in CO2 was shown when 50% volume of zeolite was replaced by biochar. The highest in CO2 reduction showed by the composition of 50% sugarcane bagasse-based biochar and 50% natural zeolite. The CO2 decreases did not accompany by the CH4 increases because mesopore-sized still dominated the adsorbents' pore size.
