How does biochar remove carbon?

Biochar is another way of getting carbon into soils. Biochar is a kind of charcoal created when biomass from crop residues, grass, trees, or other plants is combusted at tempera- tures of 300–600°C without oxygen. This process, known as pyrolysis, enables the carbon in the biomass to resist decay.

Why is biochar an efficient way to store carbon?

The first is the ability of biochar to store carbon in a stable form, preventing the CO2 from organic matter from leaking into the atmosphere, where it contributes to climate change. Biochar also enriches soil, which improves food security in developing countries and crop production almost anywhere.
