Original sentence: Because supramics consume and sequester carbon as stable compounds in useful products, they may serve to reduce carbon that would otherwise be released into the environment.The extraction can be selective to some extent by controlling the density of the medium and the extracted material is easily recovered by simply depressurising, allowing the supercritical fluid to return to gas phase and evaporate leaving no or little solvent residues
