Producing biochar from waste biomass in Wales
Climate Solution #15
Biochar is a carbon-rich, highly stable soil amendment produced as a by-product of pyrolysis, which generates energy from biomass in the absence of oxygen. When biomass decomposes, carbon and methane escape into the atmosphere. Biochar retains most of the carbon. If we bury it, that carbon can be held for centuries in the soil.
This process can produce energy, improve soils, and store carbon. This solution provides an alternative to disposing of unused biomass through burning or decomposition.
