Biochar is produced by heating biomass in an oxygen-free or low-oxygen environment so that it does not (or only partially does) undergo combustion. In this system, biochar can be produced from green waste, which helps to sequester carbon and improve soil quality. An advantage of this process is that it also produces gases that can be captured as bioenergy and fed back into the energy grid, making it a carbon negative process overall.
