Carba's biochar project validated by Isometric, U.S. Bank purchases carbon credits

Carba's biochar facility at the Burnsville Sanitary Landfill in Minnesota became the first carbon removal project validated under Isometric's methodology for biochar storage in low-oxygen environments. Following this third-party verification, U.S. Bank completed its initial purchase of durable carbon removal credits from Carba. The project converts waste biomass into stable biocarbon using a patent-pending autothermal processing system and anoxic burial, leveraging existing landfill infrastructure. This model aims to provide multi-thousand-year carbon sequestration and additional environmental benefits, establishing a framework for landfill-based biocarbon storage.
