Fremantle Seaweed lands WA’s first commercial Asparagopsis hatchery site

By AI, Created 4:19 PM UTC, May 18, 2026, /AGP/ – Fremantle Seaweed will build Western Australia’s first commercial-scale Asparagopsis hatchery and processing facility in Fremantle, backed by a $4 million state grant. The project is designed to expand local seaweed supply for methane-reducing cattle feed, support WA jobs and cut emissions across the state’s beef sector.

Why it matters: - Western Australia’s first commercial-scale Asparagopsis facility could help local producers access a steady supply of methane-reducing cattle feed. - The project is designed to support WA’s beef industry, lower emissions and reduce dependence on interstate supply. - At full capacity, the facility is projected to meet all dairy and feedlot demand across WA’s $1 billion beef industry.

What happened: - Fremantle Seaweed will establish a commercial-scale Asparagopsis hatchery and processing facility at 20 Mews Road on the Fremantle waterfront. - The project is supported by a $4,000,000 grant from the WA Government’s Investment Attraction Fund. - The announcement positions Fremantle Seaweed’s site as a hub for the company’s planned production expansion.

The details: - The facility is expected to cover the full lifecycle of production for native red seaweed, from propagation and seeding through processing. - Modelling indicates the site could meet more than 20% of national demand for Asparagopsis. - Asparagopsis has been proven to reduce methane emissions from cattle by more than 80% when included in cattle feed. - The facility is expected to produce enough seeded material to supply Fremantle Seaweed’s 32-hectare pilot farm in Debral Nara, Cockburn Sound, and a proposed 160-hectare marine lease. - Those two planned ocean leases could generate up to 576 tonnes a year of Fremantle Seaweed’s feed supplement, Reef4Beef. - That initial production could reduce methane across about 25,059 head of cattle a year and abate an estimated 56,109 tonnes of CO₂-equivalent emissions annually. - Fremantle Seaweed says the site could also support future commercial pathways for Asparagopsis and align with efforts led by groups such as FutureFeed. - The company says the facility could strengthen WA’s livestock supply chain, reduce reliance on interstate supply and support lower-emissions livestock production. - Fremantle Seaweed also sees 20 Mews Road as a potential center of WA’s emerging blue economy, with other ocean innovators exploring co-location. - Ironstate Capital Partners, a Western Australian private credit firm, supported Fremantle Seaweed’s acquisition of the property. - Fremantle Seaweed’s website is here.

Between the lines: - The project is less about proving Asparagopsis works and more about proving it can be produced reliably at scale. - That shift matters because supply constraints have limited broader adoption even as interest in emissions-cutting feed ingredients grows. - Western Australia appears to be trying to build a local production base around a climate solution that also has industrial and regional development upside. - FutureFeed’s comments suggest the market opportunity is still expanding, but manufacturing capacity remains the bottleneck.

What’s next: - Fremantle Seaweed is expected to move ahead with development of the Fremantle facility. - The company’s pilot farm and proposed marine lease will depend on the new site for seeded material. - Wider industry uptake will likely depend on whether the facility can deliver consistent output at commercial scale. - The project may also draw additional ocean-based businesses to the Fremantle waterfront site.

The bottom line: - Fremantle Seaweed is trying to turn Asparagopsis from a promising climate tool into a dependable commercial supply chain in Western Australia.
