Potential use of reject brine waste as a sustainable construction material

In countries near the ocean, the majority of the water used for household, agricultural, and industrial purposes is attained through seawater desalination. Desalination produces highly salty water, commonly known as reject brine, which can have many drastic, negative effects on the environment. The waste results in both an environmental challenge and an opportunity for sustainable resource utilization. This research work is a literature study to investigate the feasibility and potential benefits of utilizing reject brine waste as a sustainable construction material. The results revealed that reject brine has a prodigious possibility to be used as a binder, and in place of water in concrete. The use of reject brine in cementitious composites decreases CO2 emissions and makes them economical. Also, reject brine is fruitful in the stabilization of soil by increasing the mechanical properties and enhance the strength of soil. In essence, the use of reject brine from water desalination in construction is a sustainable and environment-friendly approach.
