## About

Baseternad in West Australia, and founded by Stewart Washer, David Messina (CEO), Elaine Darby, Cameron Scadding, and Matt Callahan, Rumin8 Ltd is a climate technology company that offers dietary supplements to help reduce methane emissions in livestock. In March 2026, Rumin8 Pty Ltd raised AUD 4.3 million in venture funding from AgriZeroNZ. The company’s research partners include The University of Western Australia, The University of Melbourne, Q University Australia, and the Government of Western Australia.

The company creates livestock feed supplements in liquid, oil, and solid formulations by artificially replicating the methane reductions of the red seaweed Asparagopsis and seaweed to help reduce the carbon footprint caused by animal farming. 

The company will use the March 2026 funding to expand its operations in New Zealand and progress final trials for commercial registration of its methane-abating cattle feed additives.
