A nascent biochar industry is emerging in connection with biomass power technologies that coproduce electricity and char via gasification and pyrolysis.
A single source of biomass could ostensibly create multiple revenue streams, with systems calibrated to produce more electricity, biochar or bio-oil when one is more profitable than the other.
Research shows biochar improves soil fertility, decreases water pollution and even mitigates heavy metals. The charcoal-like substance has enthusiastic support from researchers and the sustainability movement, but it has been slow to commercialize.
