Zurich-based climate technology company Cotierra has raised €2.6 million in an early-stage round. PINC, the venture arm of food and beverage group Paulig, and Carbon Removal Partners co-led the round. The sum is roughly $3 million. Cotierra builds decentralised biochar systems for agricultural supply chains.
Biochar is a carbon-rich material made from crop residues. Producers make it by heating biomass with little or no oxygen, a process called pyrolysis. It improves soil health. It also pulls carbon from the atmosphere.
Cotierra pairs reactor technology with a digital platform. The platform operates the systems, monitors them and verifies output. The company converts leftover biomass into biochar close to where residues are generated. Making it near the source avoids moving bulky residues over long distances. This cuts supply-chain emissions. It also returns carbon to the soil.
The funding supports a shift from pilots to multi-year commercial deployments. Coffee is the starting point. Chief executive Thomas Käslin said the goal is technology that is simple, reliable and scalable.
Paulig owns brands including Santa Maria and Paulig. Coffee climate resilience is central to its supply chain. Karl Swensson, investment director at PINC, said the long-term resilience and productivity of agricultural value chains are fundamental. He pointed to Cotierra’s traction with coffee traders.
Several other investors joined the round. They include Zürcher Kantonalbank, Carbon Drawdown Initiative, Better Ventures, GOTA Ventures, Hungry4Impact and Triple Impact Ventures. Climate and impact-focused angel investors also took part.
The round points to growing corporate interest in carbon removal tied to supply chains. Food companies face declining soil health and climate pressure. For some, backing on-farm decarbonisation is becoming a strategic hedge. Cotierra’s approach ties carbon removal to the farms and traders already in the supply chain.
