What Is Biochar?

Biochar carbon removal is a science-backed approach to carbon removal and its magic lies in pyrolysis: using high heat in a limited oxygen environment to transform biomass into biochar.

Through photosynthesis, biomass accumulates carbon, which via pyrolysis (heating without oxygen) becomes biochar — a highly porous, stable and durable form of carbon that can effectively store CO2 for extended periods and provide a wide range of co-benefits.
