Natural carbon cycle

CO2 is taken up by Nature’s own carbon dioxide removal factories – plants – via photosynthesis. When the biomass eventually decomposes, the stored carbon (99%) is released back into the atmosphere, closing the natural carbon cycle.
Biochar carbon cycle

Biochar effectivly hacks into this cycle by stabilising carbon within biochar. When applied to soil, this carbon will be (almost completely) removed from the atmosphere for centuries. The other product fractions of pyrolysis (biooil and pyrogas) are commonly burned on-site to heat the pyrolysis reactor and therefore end up back in the atmosphere.
