Treats to concrete: Penn State Bakery to use grad student’s carbon capture tech

Matthew Hollingham, a third-year doctoral student in architectural engineering, has developed a carbon capture system that collects carbon dioxide (CO2) from flue gas — a byproduct of boilers that contains water vapor, CO2, and nitrogen — and converts it into materials that can be used to make concrete. The system is expected to start operating this fall at the Penn State Bakery, helping to pave the way for carbon capture and utilization.
