Summary: The research conducted a life-cycle assessment on an optimized solar-driven multi-effect desalination process to investigate the extent to which the environmental impact of conventional thermal desalination processes could be minimized through the integration of concentrated solar power collectors. It was found that most of the life-cycle impact occurred during the operation phase, primarily due to electric pumping energy. The solar-driven process reduced climate change impact by 10 kg-CO2 eq. per 1 m(3) of freshwater compared to conventional methods, with the linear Fresnel collector outperforming the parabolic trough collector in terms of environmental impact.

Summary: Population growth and urbanization drive energy demand, primarily met by fossil fuels, causing adverse effects on human health and the environment. Flue gases from combustion power plants release air pollutants, such as PM, SOx, NOx, and COx, resulting in respiratory damage, acid rain, climate change, and global warming. This review examines various conventional and new technologies for managing and reducing flue gas pollutants in the combustion power plant sector. New advances including novel PM collectors, microwave systems, electrochemical systems, non-thermal plasma processes, microalgae-based methods, and wet scrubbing show potential in addressing the shortcomings of conventional systems. Integration of hybrid methods holds promise for superior control and removal of flue gas pollutants.
