Cattle's Methane Problem Has a Solution Under the Sea, and it's Grown Right Here in Australia, with Chris DeCuyper, Fremantle Seaweed
Jul 09, 2026 Episode 35
The Green Fix Podcast

Chris De Cuyper, managing director of Fremantle Seaweed, joins us to unpack asparagopsis, the red seaweed CSIRO discovered almost by accident, and the six-year journey to actually grow it at scale off the WA coast. We get into the science of how it works, why methane is the "low-hanging fruit" of climate action, and what it takes to turn a lab result into a commercial supply chain cattle farmers can actually use.

Chris also opens up on the funding journey, angel investment, equity crowdfunding, government grants, and where carbon credits fit into scaling a seaweed farm to thousands of hectares.

A great one for anyone who thinks climate solutions have to be complicated. Sometimes it's just seaweed.
