Project Type: Biomass Burial

Graphyte

Memphis, Tennessee, USA

Encases biomass preventing decomposition.

Combining photosynthesis with practical engineering, Graphyte’s Carbon Casting technology provides an immediate pathway for billions of tons of low-cost, permanent carbon removal. With levelized production costs at under $100/ton with minimal energy requirements, we can remove CO2 for 1,000+ years.

Rewind.earth

Black Sea

Sinking agricultural and forest waste.

Rewind uses cranes off of boats to sink agricultural and forest residues to the oxygenless bottom of the Black Sea, the largest anoxic body of water on Earth. Oxygenless water dramatically slows biomass decomposition. The lack of living organisms in the Black Sea limits any potential ecosystem risks. This process allows for affordable and environmentally safe carbon removal.

Vaulted Deep

Hutchinson, Kansas, USA

Buries sludgy organic waste.

Vaulted Deep injects organic waste into durable wells, where the carbon in the waste is sequestered as it decomposes. Using a specialized slurry injection technology, their process can handle a wide range of organic carbon sources with minimal energy and upfront processing. Their system has the potential to be deployed quickly at large scales.

Carboniferous

Gulf of Mexico

Sinks leftover surgar cane and corn fibre into the deep ocean. 

Carboniferous is safely and purposefully replicating the process of anoxic biomass carbon sequestration. We are a BiCRS pathway, storing terrestrial biomass in naturally forming permanent anoxic basins under the ocean.

Carba

Minneapolis, MN, United States

Permanently bury nature-based biomass for thousands of years.

Carba specializes in low energy Carbon Dioxide Removal (CDR) solutions with permanent storage. Through low temperature pyrolysis (torrefaction) we convert nature-based biomass/waste into graphitic carbon and permanently bury/store it for thousands of years.

Inter Earth

Perth WA, Australia

Partners with nature to tackle our biggest environmental challenge.

InterEarth is uses photosynthesis to capture CO2 from the atmosphere. They grow trees, harvest their above ground biomass and put that biomass, and its contained carbon, back underground.

Brilliant Planet

Akhfenir, Morocco

Grows and buries algae biomass in Morocco! 

Brilliant Planet grows algae biomass, then buries it underground where the carbon can remain trapped for thousands of years. Currently operates a pilot site in Morocco and has plans to develop a demonstration site that will be able to remove one million tonnes of carbon dioxide by 2030.
