Technology

Virtually all life has emerged from the transformation of carbon dioxide and water. Fermentation is nature’s manufacturing process.

Circe’s unique process combines the best of biology and chemistry to transform CO₂ into high-quality products. Biological methods offer precision and variety but often struggle to be price competitive. Chemical methods scale more predictably but are limited to making simpler, lower value products. Circe eliminates this tradeoff by delivering both precision and scalability—creating complex, tailored products at scale, directly from CO₂.

Made from carbon dioxide

Using CO₂ as an input gives us a major advantage in cost and scalability. Unlike traditional methods that rely on carbon-intensive, expensive raw materials, CO₂ is abundant and readily available. This approach enables us to achieve competitive costs and scale production anywhere.

Hydrogen drives our process, turning CO₂ into high-performance products. It gives us the flexibility to adapt to a rapidly evolving energy landscape, allowing us to continually optimize efficiency without changing our technology.

Built with nature

Our biosphere is the original circular process. With it as our guide, we ensure efficiency and minimal waste. Our primary byproduct is water, keeping our impact low and embodying the circular economy principles essential for sustainable growth.
