Abstract: This study proposes the optimum synthesized of pure MgO from MgO precursor, MgC2O4. PC production contributes 5 to 10 % of anthropogenic CO2 emission worldwide, mainly due to high calcination temperature, approximately (~1450 °C) and energy required for power generation, significantly contributing to global warning. As the environmental impacts of construction materials are becoming a critical concern, the development of novel alternatives with lower energy requirements and associated CO2 emissions is more crucial than ever. As a result, one of the sustainability initiatives in the cement industry is to develop sustainable cements alternatives. Reactive MgO cements recently attracted great attentions due to significantly lower calcination temperature (~700 °C) greatly reducing the energy usage and CO2 emissions. However, traditional MgO production ways involve more energy consumption because more raw materials are required despite lower calcination temperature, how to sustainably produce MgO becomes our main target in this project. This project proposes a novel method to synthesize MgO from reject brine through precipitation process by C2H2O,
