Cotierra raises €2.65M to expand biochar for tropical agriculture

Cotierra, a Zurich-based climate technology firm, has raised €2.65 million to accelerate the commercial scaling of its decentralised biochar production technology for tropical agriculture. The latest funding brings Cotierra's total capital raised to €4.19 million since its founding.

The company specialises in converting agricultural waste into biochar directly near production sites, a strategy designed to improve soil resilience and productivity for farmers in tropical regions while lowering carbon emissions across supply chains. According to Cotierra, decentralised biochar production offers a dual benefit: improving soil health and enabling more sustainable agricultural practices by sequestering carbon.

The funding will support Cotierra's transition from field deployments to a repeatable commercial scale, a step viewed as critical for validating the technology's impact on both farm productivity and environmental outcomes. The company sees significant opportunity in tropical agriculture, where soil degradation and climate pressures have constrained yields and increased risks for producers.

For European stakeholders, Cotierra's model presents a potential blueprint for reducing emissions in food and beverage supply chains that source from Latin America and other tropical regions. Biochar has drawn attention as a climate solution because it locks carbon in soil while enhancing nutrient retention and water holding capacity—key factors for long-term agricultural resilience.

The commercial viability of Cotierra's approach will depend on successful scaling and demonstrated improvements in soil health and productivity. The company has not disclosed its immediate market targets or specific application plans for the new funds. However, the investment signals growing interest in climate technology that addresses both environmental and agricultural challenges at source.

For farmers in tropical regions, the adoption of biochar could mean more robust soils, potentially higher yields, and a pathway to participate in low-emission supply chains—a factor of growing importance for exporters to Europe and other markets with tightening sustainability standards.
