Organic Wastes to Increase CO2 Absorption

Abstract

The objective of the study was actually the investigation of the effect of various organic wastes on the ability of urine in absorbing CO 2 . Urine alone or mixed with olive-oil-mill waste waters (O), poultry litter (P) or meat bone meal (M) was used on the absorption of CO 2 from a gas bottle. The absorption capacity (1.35 - 2.85 gCO 2 /gNH 4 ) was bigger than other solvents such as ammonia and amines. The range of CO2 absorption was significantly bigger for the organic mixtures P and PM with urine (9.1 - 11.8) g/L than urine alone 6.5 g/L. These organic wastes could be used to increase CO 2 absorption in urine and reduce gas emissions.
