Carbon dioxide removal that is permanent, affordable, and immediately scalable.
Carbon Casting is a new approach to carbon removal that leverages readily available biomass, such as residues from timber and farming operations. We dry and compress it into dense carbon blocks protected by an environmentally-safe, impermeable barrier, and then store these blocks in underground sites with state-of-the-art monitoring. Carbon Casting preserves nearly all the carbon captured in the biomass and consumes very little energy in the process. Combining photosynthesis with practical engineering, Graphyte’s Carbon Casting technology provides an immediate pathway for billions of tons of low-cost, permanent carbon removal.
