What Fremantle Seaweed does
Fremantle Seaweed Pty Ltd is an Australian ocean-tech aquaculture company founded in 2020 and headquartered in Fremantle, Western Australia. The company cultivates the native red seaweed Asparagopsis in offshore waters off Western Australia's coast and processes it into Reef4Beef, a cattle feed supplement that reduces ruminant methane emissions by over 80% at a 0.5% feed inclusion rate and improves feed conversion efficiency by 7.4%. Core operations span a 32-hectare approved marine aquaculture lease at Derbal Nara (Cockburn Sound) — with proposed expansion to approximately 160–200 hectares across two sites — and a newly acquired commercial-scale hatchery and processing facility at 20 Mews Road, Fremantle. The company is a cultivation partner with FutureFeed, the global IP holder (originating from CSIRO) for Asparagopsis in livestock feed, and is pursuing a commercial IP license.
The business model centres on selling Reef4Beef to Australian dairy and feedlot cattle producers, but the product is offered at zero direct cost to farmers. Revenue is intended to be captured downstream through Australian Carbon Credit Units (ACCUs) under a methodology submitted to the Emissions Reduction Fund, biodiversity credits generated by the ocean infrastructure, and low-carbon consumer premium pricing for beef and dairy products. The company targets Australian cattle producers under pressure to meet the red meat industry's carbon-neutral-by-2030 target. Distribution is via direct field sales and the FutureFeed licensee network, supported by marketing channels including the corporate website, LinkedIn, Facebook, Instagram, Vimeo, and earned media coverage in outlets such as the Australian Financial Review.
Fremantle Seaweed has raised approximately $7.6 million AUD cumulatively through a mix of government grants ($4M WA Investment Attraction Fund, Blue Gravity grant, $50K WA Nature Tech Accelerator), equity crowdfunding ($1.26M via Birchal in 2024 and ~$2.3M via OnMarket in late 2025), and impact investment from Third Hemisphere's investment arm. The company has been recognised by the World Economic Forum's 1000 Ocean Startups coalition and is undergoing pre-assessment for ASC/MSC Seaweed Standard certification. Its ecosystem includes research collaborations with the University of Western Australia and Murdoch University, partnerships with South Metro TAFE and the South West Aboriginal Land & Sea Council, and membership in the Australian Sustainable Seaweed Alliance. The company operates with 1–10 employees and is in the transition from proof-of-concept to commercial-scale production.

Revenue model
- Asparagopsis Feed Supplement Sales: Sale of Asparagopsis-based cattle feed supplement (Reef4Beef) to dairy and feedlot cattle producers. At full commercial scale, the company plans to supply large-volume methane-reduction seaweed to Australian cattle producers. Product offered at zero cost to farmers with value captured through carbon credit schemes, low-carbon product premiums, and biodiversity credits.
- Carbon Credits: FutureFeed has submitted a methodology with the Emissions Reduction Fund for Asparagopsis feed supplement to be recognised by Australian Carbon Credit Units (ACCU) scheme, enabling revenue generation from carbon credits.
- Consumer Premium Products: Market research shows 1 in 4 consumers willing to pay 15% premium on carbon neutral beef products, and 30% of Australians willing to pay additional $1 for burger from low-emitting cows fed Asparagopsis. This enables premium product pricing for farmers using the supplement.
- Biodiversity Credits: Biodiversity credits emerging as way to offset costs by enhancing local biodiversity via innovative ocean infrastructure, creating additional revenue streams for the company.

Product overview
Fremantle Seaweed is an ocean-tech company cultivating Asparagopsis seaweed in Western Australia's pristine waters for the production of methane-reducing cattle feed supplements. The company's primary product is Reef4Beef, an Asparagopsis-based feed supplement that reduces cattle methane emissions by over 80%. Operating from a 32-hectare pilot farm in Derbal Nara (Cockburn Sound) and developing a commercial-scale hatchery facility, the company is scaling production to meet national demand. Asparagopsis is a native Australian red seaweed discovered by CSIRO to be the most efficient natural methane supplement for ruminant livestock, working through the bioactive compound bromoform that inhibits methane-producing microbes in the cow's gut. Fremantle Seaweed is a cultivation partner with FutureFeed, the global IP holder for Asparagopsis in livestock feed.

Fremantle Seaweed competitors and assessment
Company assessmentEmerging players
- Cascadia Seaweed: British Columbia-based seaweed cultivation company producing multiple native seaweed species for agriculture, food, and biotech applications. Comparable in ocean-based cultivation infrastructure and scaling model, though not focused specifically on the cattle methane end market.
Direct peers
- CH4 Global: New Zealand and Australia-based company developing Asparagopsis-based feed supplements to reduce enteric methane in cattle. Most direct competitor in the Asparagopsis-to-feed value chain targeting Australasian beef and dairy producers with similar zero-cost farmer proposition tied to carbon revenue.
- Sea Forest: Tasmania-based Asparagopsis cultivator producing seaweed-based methane-reducing cattle feed supplements for Australian livestock producers. Directly comparable in core product (Asparagopsis feed), target market (Australian cattle), and business model (cultivation partner in FutureFeed ecosystem).
- Symbrosia: Hawaii-based startup cultivating Asparagopsis for livestock methane reduction, supplying feed supplements to US and Asian markets. Same core technology stack (Asparagopsis + bromoform), same end use case (cattle feed), serving a complementary geographic market.
- Volta Greentech: Sweden-based company developing Asparagopsis-based feed supplements to reduce methane emissions from dairy and beef cattle in European markets. Direct technology peer competing in the same global Asparagopsis-to-feed value chain.
Others
- FutureFeed: CSIRO-established entity holding global IP for Asparagopsis in livestock feed applications. Functions as the licensor and ecosystem orchestrator rather than direct competitor; Fremantle Seaweed is a cultivation partner pursuing a commercial IP license from FutureFeed.
- Australian Sustainable Seaweed Alliance (ASSA): Industry alliance of which Fremantle Seaweed is a member, working to develop the Australian seaweed industry through collaboration and standards. Ecosystem-level peer representing the broader seaweed industry coordination layer rather than a commercial competitor.
Broad incumbents
- DSM-Firmenich: Global animal nutrition and health major that has commercialized Bovaer (3-NOP), a synthetic feed additive delivering comparable methane reductions in cattle. Represents the incumbent, scalable, regulator-approved alternative competing for the same farmer adoption wallet.
- Elanco Animal Health: Large animal health and nutrition company with established feed supplement distribution into global beef and dairy markets. Indirect competitor with distribution scale and farmer relationships that seaweed-based methane solutions must access to scale.
Regional players
- Blue Carbon Yamba: Australian-based company developing offshore seaweed farming primarily for carbon sequestration and ecosystem services rather than cattle feed. Adjacent regional player in Australian ocean-based seaweed cultivation with overlapping infrastructure but different end markets.
