Carbon Dioxide Removal
Biochar
Biochar is a substance created when organic material like agricultural waste is burned in the absence of oxygen. That process, called pyrolysis, creates a carbon-rich product that is stable or biologically recalcitrant. By transforming biomass into biochar, the carbon in the plant material is locked up instead of being released into the atmosphere when the biomass is burned or biodegraded in soil. Biochar is added to soil to sequester carbon dioxide in the soil.
