Many believe biochar merely moves carbon from one short-term reservoir (the biosphere) to another (the soil). But this overlooks a key aspect of the carbon cycle: Biochar transforms short-lived carbon into a long-term stable form through pyrolysis, effectively preventing its rapid re-release into the atmosphere .

Studies show that biochar produced at high temperatures (550–600°C) can lock carbon away for hundreds to thousands of years, reducing greenhouse gas emissions and enhancing soil health and agricultural productivity .

This means biochar plays a critical role in carbon sequestration and agricultural sustainability.
