Terra Carbon is a portable, self-sustaining carbon capture system that converts atmospheric CO₂ into building materials. Using a humidity-swing resin, it passively absorbs and releases CO₂, which is then mineralized with silicate rocks. The resulting carbon-rich base supports mycelium growth, forming biodegradable bricks and pavers. Powered by solar and wind energy, Terra Carbon operates off-grid and adapts to diverse environments—offering a scalable solution that unites carbon capture with sustainable construction.
