About Circlair

Air purification for sustainable agriculture and industry

Our origins

Circlair grew out of research at KU Leuven, where a doctoral project laid the foundation for developing technology to efficiently capture ammonia, odor, and fine particulate matter — and, where possible, recover them as valuable resources.

Our mission

Our mission is straightforward: reduce emissions and close material cycles. With our circular solutions, we convert ammonia, odor, and fine particulate matter into valuable resources. In doing so, we aim to provide businesses with a sustainable, reliable, and practical solution for emission management and the circular use of nitrogen.

Our core values

  • Innovative: We develop technology on the basis of thorough research and new insights.
  • Circular: Nitrogen is reused as a valuable raw material.
  • Science-based: All solutions are grounded in proven processes and protocols.
  • Reliable: From lab demonstration to full-scale installation, quality and consistency are at the heart of everything we do.
