ABSTRACT

The aim of this work was to investigate the effect of urine on the absorption of greenhouse gases such as CO(2). Human urine diluted with olive-oil-mill wastewaters (OMW) could be used to capture CO(2) from flue gas of coal-fired power plant and convert CO(2) emissions into valuable fertilizers (mainly, NH(4)HCO(3)) that can enhance CO(2) sequestration into soil and subsoil layers. Thus, the CO(2) emissions could be reduced between 0.1 and 1%. The proposed strategy requires further research to increase CO(2) absorption and assess the risks associated with wastewater reuse and xenobiotics in the agroecological environment.
