Biomass is material from vegetation, it can be used as a fuel in various boilers and combustors. Biomass fuels emit carbon dioxide (CO 2) when carbon reacts with oxygen (O 2) during combustion but because the biomass has absorbed the carbon from the CO 2 in the atmosphere during its growth, the combustion of biomass is considered to be CO 2
