Turning methane into protein — inside the cow

Microbial feed additives designed to reduce methane and improve feed efficiency in dairy production.
Explore our approach Partner with us

Reduce methane

Reduce methane at the source.

Improve feed efficiency

Turn lost feed energy into nutritional value.

Scale through feed industry partners

Designed for integration into existing feed systems.

OUR APPROACH

GreenCow develops microbial biosolutions based on methane-consuming biology.

We convert cow methane into microbial protein directly in the rumen.

One biological process.
Two value streams.

• Reduced methane emissions

• Improved feed efficiency

HOW WE SCALE

Farmers adopt

Driven by performance and ROI.

Dairies and retailers create demand

Scope 3 targets drive market pull.

Feed companies scale

Existing feed systems enable deployment.

We don’t build distribution — we plug into it.

VALIDATION & TRACTION

  • Methane-to-value biology validated in vitro
  • Up to ~70% methane reduction and improved digestibility demonstrated in vitro
  • Controlled in vivo validation underway
  • Developed through the MethaCow Grand Solutions collaboration (Innovation Fund Denmark) – read announcement
  • Supported by academic and industry expertise

Partner with us to bring biological methane conversion to market

Together with feed industry partners, research institutions and investors, we are advancing scalable methane-to-value solutions for dairy production.
