Carboniferous offers innovative carbon capture and storage by permanently sequestering agricultural waste in deep, oxygen-deprived basins using Anoxic Biological Carbon Sequestration (ABC’S). This scalable, scientifically validated approach aims to remove...
Technology Focus
Carboniferous addresses the problem of excess atmospheric CO₂ by using a solution called Anoxic Biological Carbon Sequestration (ABC’S). This method involves collecting agricultural waste, such as corn stalks, wheat straw, and sugarcane bagasse, and depositing it into deep, hypersaline anoxic basins (naturally oxygen-deprived underwater zones). These conditions significantly slow down decomposition, preventing carbon from returning to the atmosphere as CO₂ or methane. By preserving plant biomass in these “dead zones,” Carboniferous aims to permanently lock away carbon for over 1,000 years, offering a scalable and scientifically validated method of carbon removal.
