Mantel Analysis: $32M Raised
What is Mantel?
Mantel develops molten-borate materials that capture carbon dioxide at high temperatures inside boilers, kilns, and furnaces. The technology enables efficient carbon capture previously unattainable in industrial heat systems. By reducing energy losses by over 60%, it cuts capture costs in half and supports net-zero emissions across cement, steel, and power generation.
