Kuala Lumpur: Students Omar bin Issa Al Barmani and Tamim bin Yousef Al Maamari, guided by their supervisor Majid bin Khalfan Al Muqbali, created AEROCARBON—a low-cost, eco-friendly device that filters vehicle exhaust using fragments of barodite (also spelled “braudtite”) rock. The innovative filter works by triggering a chemical reaction between carbon dioxide, humidity, and the rock, converting the harmful gas into calcite, effectively reducing CO₂ emissions at the source.

The invention underwent rigorous testing, including lab experiments at Sultan Qaboos University, which confirmed its effectiveness in significantly cutting exhaust emissions. The compact system includes a car exhaust filter, circular mesh, Arduino board, screen, and CO₂ sensor—making it both practical and scalable.

The project won first place in the environmental category at the 36th International Exhibition of Inventions, Innovation and Technology (IIEIT), held in Kuala Lumpur in 2025. It was also honored with a special award from Saudi Arabia’s Tuwaiq Academy, further cementing its regional significance.

Their journey began with success at the National Olympiad for Innovations, Robotics, and AI, where their idea stood out among entries from across Oman. Supported by the Innovation and Scientific Olympiad Department, the students received expert guidance and technical backing throughout the development process.

With a patent already secured, the team now aims to expand the application of their invention and inspire a wider culture of environmental responsibility and innovation throughout the Sultanate.
