• Early Market Demand: Terraset, a nonprofit climate fund, committed to a six-figure carbon credit pre-purchase from Terraton’s Three Mountains Cocoa project in Ghana, signaling strong market interest.

Potential Impact

The funding positions Terraton to meet growing corporate demand for verifiable carbon removal solutions. By leveraging agricultural waste, Terraton not only sequesters carbon but also creates new revenue streams for farmers in emerging markets. The company’s focus on scalability and accessibility could make biochar a cornerstone of global carbon removal efforts, with 2024 data indicating biochar accounted for over 250,000 tonnes of carbon removal, outpacing other methods.

Terraton, headquartered in San Francisco, is a climate technology startup dedicated to scaling carbon dioxide removal (CDR) through biochar production. Biochar is produced via pyrolysis, a process that converts agricultural waste into a stable, carbon-rich material that sequesters CO2 in soil for centuries while enhancing soil fertility. Terraton’s innovative “business-in-a-box” model provides agribusinesses with the tools, financing, and operational know-how to establish biochar production facilities. This approach aims to overcome barriers such as high upfront costs, operational complexity, and limited market access, particularly in emerging markets like Africa.

Terraton has already established two operational facilities: one in Ghana, processing cocoa waste, and another in Kenya, utilizing nut processor residue. These facilities, owned by local businesses, are expected to collectively remove 20,000 metric tons of CO2 annually, demonstrating the practical viability of Terraton’s model. The company also develops a software-as-a-service (SaaS) component to manage plant operations, measure carbon sequestration, and verify carbon credits for sale to corporations seeking to offset emissions.
