A Taste of a Better Future in Every Bite

August 2025, CH4 Global hosted an unforgettable wagyu dinner at the Coopers Brewery Visitor Centre—featuring the first-ever low-methane Methane Tamer™ Wagyu beef, raised on our asparagopsis-based supplement for 400 days.

The beef, sourced from the Sandalwood Feedlot in Queensland, was fed a daily dose of our methane-reducing additive, cutting emissions by up to 90%, with no impact on taste, performance, or daily operations.

CH4 Global Honored in the 50 SDG Leaders - Harnessing Seaweed to Mitigate Livestock's Climate Impact

The search for an effective livestock methane reduction solution has led to an unexpected source: a remarkable red seaweed known as Asparagopsis. This seaweed grows in temperate and tropical waters and produces compounds that have evolved as a natural defense mechanism in marine environments. When added to cattle feed in small amounts, these same compounds disrupt the methane-producing process in the rumen, the first chamber of a cow's digestive system.

CH4 Global has pioneered a cattle feed additive based on Asparagopsis, which has been formulated to ensure consistent, stable levels of methane-reducing compounds. The product integrates seamlessly with existing feeding systems, allowing farmers to adopt it without significant operational changes.

Production Begins at CH4 Global’s First Full-Scale EcoPark

CH4 Global opened phase one of its first full-scale EcoPark, where it has begun to grow and process Asparagopsis in 10 large-scale cultivation ponds with a combined capacity of 2 million litres - capable of producing 80 metric tonnes of the seaweed each year. Over the next year, the facility will expand to 100 ponds capable of producing enough Asparagopsis to serve 45,000 cattle per day – a significant step toward meeting demand from CH4 Global's existing commercial partners in Australia and beyond. With additional investment, the facility could eventually expand to 500 ponds capable of serving hundreds of thousands of cattle per day.

World Farmers' Organisation & The Future of Food Series

Heath Tiller, a feedlot farmer in South Australia, is faced with how he can leave a legacy to his children through the management of his farm, with climate change as a constant threat. He’s been working with CH4 Global to help optimize farm usage and testing their first feed additive formulation with star ingredient, Asparagopsis seaweed, shown to reduce enteric methane by as much as 90%. The results exceed expectations, with benefits for the health of the animals and an attraction for the customer.

FAQs

Methane and Climate Change

Over the next 20 years, methane will have more than 80 times the climate warming impact of carbon dioxide, according to the 2021 report from the Intergovernmental Panel on Climate Change (IPCC). Methane’s damage is mostly within the 20 years after it has been emitted.

Asparagopsis and Methane Reduction

Asparagopsis seaweed contains bromoform (CHBr3), which is a key “active” ingredient in our formulations. When fed to cattle, bromoform disrupts enzymes of the microbes that live in the animal’s rumen and produce methane gas during digestion. The net result is a reduction of enteric methane emissions of up to 90%.

Asparagopsis and Safety

The results of four peer-reviewed and published studies in dairy cows and beef cattle show that whole, freeze-dried Asparagopsis is safe and effective when used as intended. The studies show animals maintain their health while consuming Asparagopsis. No elevated levels of bromoform are found in meat or milk when Asparagopsis is used as intended and at inclusion levels that deliver the target bromoform amount.

Sustainability of Asparagopsis Production

CH4 Global is working to ensure Asparagopsis aquaculture is sustainable, including tank, and in ground cultivation. The CH4 Global EcoPark™ strategy bases our growth mainly on cultivation in ground, and to a lesser extent in tanks, thereby safely enabling Asparagopsis aquaculture in regions where the seaweed is non-native.
