Charm Industrial removes atmospheric carbon dioxide by converting waste biomass into bio-oil and injecting it underground for permanent storage. The high carbon and low energy bio-oil they create is produced via fast pyrolysis, a process during which biomass feedstock is heated to a high temperature in the absence of oxygen, causing the chemical structure of the biomass to change so that the carbon is stabilized and resistant to decay.
The credits for this project are generated by injecting a substance that shares similarities with bio-oil, a byproduct of biodiesel production that would otherwise have been used in cattle feed. The injectant was transported to the partner’s injection site in the Midwest, where it was injected into a deep injection well permitted under the EPA’s Underground Injection Control program.
