Cement production is one of the largest sources of global CO2 emissions and with demand growing worldwide, there is enormous pressure to address these emissions. Inevitable process emissions can be captured and the CO2 can then be used as a feedstock for carbon-based products. This study was carried out toward fuel production with microalgae (Chlorella Vulgaris ISC-23) as an approach for bio-stabilization of CO2 in the cement industry. A life cycle assessment model (LCA) of CO2 biofixation was developed using SimaPro 8.3 in two different scenarios (see Figure 1) for experimental data from the literature on simulated cement kiln emissions, including dust. The results show that, for each ton of cement produced, algae can capture 185 kg of CO2 and convert it to fuel, which leads to at least 25% of GHG emissions saving
