Waste biomass is typically burned or left to decompose resulting in the already captured CO₂ returning to the atmosphere. However by heating the waste-biomass to high temperatures (>500ºC) without oxygen - a process called "fast pyrolysis" - it is possible to turn it into bio-oil.
Bio-oil is a liquid similar to crude oil but due to certain qualities is a poor fuel substitute. But by pumping it into large, underground wells it can make excellent geological storage keeping the carbon locked away for millennia.
We partner with Charm Industrial to remove CO₂ with bio-oil underground injection.
