"A chemist finds a way to cut supersalty discharge and CO2 as the Middle East relies ever more on seawater desalination.
Farid Benyahia wants to solve two environmental problems at once: excess carbon dioxide in the atmosphere and excess salt in the Persian Gulf (aka the Arabian Gulf). Oil and natural gas drive the region’s booming economies—hence the excess CO2—and desalination supplies the vast majority of drinking water, a process that creates concentrated brine waste that is usually dumped back into the gulf.
Benyahia, a chemical engineer at Qatar University, thinks he may have hit on a neatly efficient way to address the problem. “The goal is to solve two nasty environmental problems with one smart solution and generate useful, marketable products to offset partially the cost of storing CO2,” he says."
