Africa’s Waste Management Problem

West Africa’s biomass waste—including cashew shells and palm residues—is burned or discarded, missing a gigaton-scale opportunity for energy, carbon capture, and growth.

Building a Circular Economy for the Poorest Farmers by returning biochar in Cashew Fields, improving soil health & yield

Crop Residue

300 million metric tonnes per year (2024).

CO₂ Emissions

500 million metric tonnes per year.

Economic Value

$10 billion potential if 50% of biomass is converted to biochar.

The Valency Project

Transforming Cashew Shell Waste in Partnership with Valency International 

Revāta Carbon, in partnership with Valency International, is transforming cashew shell waste in West Africa into biochar and renewable energy. Using Valency’s facilities in Nigeria and Ivory Coast, the project processes 35,000 tonnes of waste annually, cutting 6 million tonnes of CO₂ emissions.

Powered by RevPyro technology, it tackles emissions, waste mismanagement, and soil degradation while creating income opportunities for farmers.

Over the next 2-3 years, the initiative will expand to other biomass value chains, scaling sustainable impact.
