Impact

Following six years of research and product development, Sea Forest began commercialising SeaFeed in June 2025. By December the same year, more than 110,000 beef cattle were receiving the supplement, delivering a reported annualised abatement of over 210,000 tonnes of carbon dioxide equivalent.

The environmental gain is paired with an economic incentive. Sea Forest estimates that using SeaFeed generates a net benefit of A$0.40 per grain-fed animal each day through better feed conversion and productivity, before potential carbon-credit income.

The product is also moving beyond cattle. By December 2025, more than 10,000 sheep were receiving SeaFeed. Fast Retailing, the parent company of Uniqlo, subsequently launched its first low-carbon wool collection connected to this work in April 2026.

SeaFeed has also been used to reduce emissions from dairy production, with lower-emissions milk and cheese reaching major food retailers. Partnerships and trials involving Woolworths, Myton Food Group, Mitsui & Co. and Mars point to a broader role for the product across food and fashion supply chains.

The effectiveness of SeaFeed proves that farmers do not have to choose between strong animal performance and lowering methane emissions, resulting in a positive feedback loop.

Future outlook

Sea Forest plans to expand across Australian grain-fed and grazing cattle, with a commercial pipeline exceeding 600,000 animals. A large-scale grazing trial is due to begin in 2026, supported by new delivery methods suited to extensive grazing operations.

International expansion is planned for Africa and Brazil, followed by the United Kingdom and Europe. Sea Forest is also targeting commercial water-based delivery by 2027 and regulatory approval in the United States by 2028 or 2029.

The ambition is to make a tiny addition to an animal’s diet produce an outsized result: less methane, more efficient farming and lower-emissions food and fibre.
