The contributing effect of carbon dioxide (CO2) emissions from solid-wastes to the increasing global warming was studied. This study assessed CO2 removal by adsorbents in a solid-wastes management facility in Akure, Ondo State, Nigeria. An exploratory study design with an intervention component was adopted. A CO2 extractor utilizing adsorbents consisting mixtures of Sawdust and Potassium Hydroxide (SKH), Sodium Hydroxide (SSH) and Calcium Hydroxide (SCH), all at ratio1:1 was designed and fabricated. Five replicates of adsorbents were integrated into the equipment to capture CO2 from 5kg samples of solid-wastes burnt under controlled conditions. The potential CO2 was determined by ultimate analysis, while the concentration of CO2 adsorbed was obtained by finding the difference between the concentrations of the CO2 at the inlet and outlet chambers of the extractor measured with P-Sense plus CO2 meter AZ-7755. The effectiveness of the extractor combined with adsorbents was determined by comparing adsorbed with potential CO2. Data were analysed using descriptive statistics and ANOVA at �.�. The mean potential CO2 was 160.0+42.0ppm. The mean CO2 adsorbed were 99.0+24.0, 45.0+24.1 and 30.0+13.0 ppm for SKH, SSH and SCHrespectively. The effectiveness of SKH in the capture of CO2 was 61.9% as against 20.8% and 18.8 % obtained from SSH and SCH respectively.
