In this episode of the Blue Earth Podcast, Guy Hayler sits down with Mayleah House and Chris De Cuyper from Fremantle Seaweed to explore one of the most promising nature-based climate solutions emerging from Western Australia. Fremantle Seaweed grows asparagopsis offshore and turns it into a cattle feed supplement proven to reduce methane emissions by up to 90%, while improving feed efficiency for farmers. It’s a rare example of science, nature and commercial viability aligning to tackle a major source of global emissions. They discuss the science behind the breakthrough, why growing seaweed in the ocean matters, how supermarkets and food supply chains are driving demand through Scope 3 targets, and what it takes to build an infrastructure-heavy climate startup from the water up.Recorded shortly before Mayleah travelled from Australia to pitch at the Blue Earth Investment Forum, this conversation connects ocean innovation with the capital and partnerships needed to scale it worldwide.
