ClearExhaust LLC is a startup spun out of Qatar University focused on developing advanced, innovative solutions to eliminate harmful vehicle emissions, especially from diesel engines. The company, led by Prof. Samer Ahmed, partners with institutions and industries to commercialize its technology for trucks, buses, and potentially broader applications, aligning with Qatar’s sustainability goals.
Unlike the existing filters, our patented technology Smokeless Exhaust Tube is capable of eliminating completely (100%) the smoke emissions of diesel engines and reduce other greenhouse gases by about 30%
