Summary

Kisiwa Farming and atmosfair run a pyrolysis plant on Mafia Island in Tanzania, producing biochar from surplus coconut biomass. The biochar is used to store carbon, improve soil quality and increase crop yields, as well as replacing conventional fertilisers on the organic farm. The project aims to create a sustainable circular economy on the island that benefits all stakeholders.

How carbon is being removed

Biomass Carbon Removal and Storage (BiCRS) involves storing the carbon contained in waste biomass—organic material from living or recently living organisms. BiCRS works by halting or slowing the decomposition of biomass, enabling the carbon it contains to be stored long-term. This can be achieved by converting biomass into materials that decompose more slowly—such as biochar or bio-oil—or by storing it in environments where decomposition is slowed. For BiCRS to count as carbon removal, the biomass must be replenished to ensure additional carbon dioxide is drawn from the atmosphere.
