Cotierra Lands $3Mn to Scale Decentralized Biochar Technology
Sep 29, 2026 | By Oliver Bennett

Zurich-based climate technology company Cotierra has raised $3 million to scale its technology from successful field projects to larger commercial operations. The latest funding brings the company’s total funding raised since its founding to $4.75 million.
In tropical farming regions, large amounts of agricultural waste are often left unused. At the same time, farmers are facing declining soil quality and more frequent extreme weather, which can make farming more difficult.
Food and beverage companies are also under pressure to reduce emissions from their supply chains, while climate change is making agricultural production less predictable.
Cotierra is working to address these challenges by developing technology that makes decentralized biochar production easier to deploy and scale across tropical farming communities.

Thomas Käslin, CEO and Co-Founder, Cotierra said: "We have shown that decentralised biochar offers a highly effective pathway to decarbonise and strengthen tropical agricultural value chains where biomass is widely dispersed. Now we are making it simple, reliable and scalable. Our ambition is to make it the standard solution for agricultural companies to strengthen farmer productivity and resilience while reducing emissions and removing carbon across their supply chains."
Karl Swensson, Investment Director, PINC said: “What stood out to us about Cotierra is the strong traction the company has achieved with coffee traders through a solution that delivers value for farmers, traders and coffee companies alike. We believe decentralised biochar can play an important role in reducing emissions and improving resilience in coffee-growing regions.”
