CH4 Global's seaweed feed additive earns AgTech Startup of the Year title 

CH4 Global, the maker of an innovative seaweed-based feed additive based in Australia that reduces methane emissions in cattle, announced it has been awarded "AgTech Startup of the Year" in the 5th annual AgTech Breakthrough Awards programme.

The award is being conducted by AgTech Breakthrough, a leading market intelligence organisation that recognises the top companies, technologies and products in the global agricultural and food technology markets today.

The company's flagship solution is Methane Tamer, a feed additive derived from Asparagopsis, a red seaweed, that has been shown to reduce methane emissions from cattle by up to 90% when added at just .5 % of their daily diet. When consumed, the seaweed disrupts an enzymatic process in a cattle's digestive system. Developed through a proprietary cultivation and processing method, the solution is scientifically validated and safe.

Methane Tamer™ Beef Feedlot is the company's targeted formulation designed specifically for beef cattle in feedlot operations. It delivers a standardised 75% reduction in feedlot enteric emissions throughout its shelf life, and additional formulations are in the pipeline, including Dairy Feedlot, Grazing Dairy, Grazing Beef, Sheep, and Goats.

In addition, CH4 Global's pond-based EcoPark is the world's first commercial-scale Asparagopsis production facility in South Australia. The facility's production model slashes operational costs by up to 90 per cent versus conventional seaweed farming. CH4 Global has also forged strategic partnerships with major organisations to help fast-track adoption across diverse supply chains and markets.
