CH4 Global, Inc., has kicked off the first phase of its full-scale EcoPark in Louth Bay, on the Eyre Peninsula, working to grow and process Asparagopsis seaweed and cut cattle methane emissions.
The facility has started with 10 large-scale cultivation ponds having a total capacity of 2 million litres. These are capable of producing 80 metric tonnes of seaweed annually. The Asparagopsis is a native South Australian red seaweed that has been found to reduce methane emissions from cows by up to 90 per cent.
Within the next year, the company aims to expand the facility to include 100 ponds, increasing the production capacity massively. This expansion is designed to produce enough Asparagopsis to feed 45,000 cattle daily, addressing the demand from CH4 Global’s commercial partners both in Australia and internationally. With further investment, the facility’s capacity could reach 500 ponds to support hundreds of thousands of cattle every day.

“I congratulate CH4 global on this significant achievement,” shared South Australian Premier Peter Malinauskas
“South Australia is already a world leader in decarbonisation. Helping the rest of the world achieve this challenge presents an incredible opportunity to deliver a more complex economy and more jobs for South Australians.
“CH4 Global’s EcoPark is a shining example of what we can achieve – using Research and Development to develop new industries.
“Propagating a local seaweed to feed cattle has the potential to drastically reduce methane emissions from agriculture, both here and around the globe.”
The EcoPark incorporates research and development facilities, a seedling hatchery, patented in-land growth ponds, and innovative harvesting and drying technologies. This supports the end-to-end production of CH4 Global’s Methane Tamer products.
“The EcoPark allows us to now grow Asparagopsis at-scale, providing more Methane Tamer to the feedlots and farmers we are already working with, and to meet the needs of the increasing number of organisations contacting us to help them change the feeding habits of their cows as we start bending the climate curve,” said Dr Steve Meller, founder and Chief Executive of CH4 Global.
“We are well and truly working towards eliminating one billion metric tons of carbon dioxide equivalent emissions and reaching 150 million cattle by 2030 through our local and international partnerships with feedlots and farmers, and it’s fantastic to see beef from these cows hitting shelves in Australia and heading overseas.”

Not only is the pond-based system cost-effective, but they also claim it can reduce production costs by up to 90 per cent compared to traditional tank-based methods.
Alongside this, the broader goal for CH4 Global is dramatic – preventing the creation of one gigatonne of CO2 emissions by 2032, targeting 150 million cattle which constitutes 10% of the global cattle population. This initiative matches local and global environmental management strategies.
The team at CH4 are also working alongside farmers and local communities in SA, Queensland and overseas to reach these goals.
“Along with supporting farmers in South Australia, Queensland and overseas to reduce emissions, we’re working closely with the Eyre Peninsula community by having worked with local contractors to build the EcoPark, sourcing local materials and providing regional jobs,” shared Dr Melller.
CH4 Global has also been collaborating with First Nations communities in South Australia, aiding in the planting of native species, developing a land management plan, and providing a communal gathering space.
The environmental impact of the project extends to sustainable site management practices. In remediating the 14ha site, CH4 Global cleared 5,000 tonnes of concrete tanks, recycled 11.76 tonnes of HDPE in Adelaide, reused 10 tonnes of plastic equipment within the community, and recycled five tonnes of steel, highlighting their commitment to a sustainable and environmentally friendly operational framework.
