Cattle produce a massive amount of methane, accounting for about a third of New Zealand's greenhouse gasses, and 10% of Australia's. 10% is similar to the impact of personal transport!


Meanwhile, consumers are increasingly wanting eco-friendly options, and farmers and brands are looking for cost-effective and easy ways to improve their environmental sustainability.


Sway Aquaculture's methane-reducing seaweed allows farmers to future-proof their operations by meeting evolving consumer demands.

3 Step Solution


Methane-Reducing Seaweed for Cows


We are undergoing pilot trials for mass-scale farming of Asparagopsis Taxiformis on the shores of the Philippines.


The Philippines has a rich history of seaweed farming and has excellent growing conditions. It allows us to achieve the scale required to feed a meaningful amount of cows.

The Science

Asparagopsis Taxiformis is a species of red seaweed found worldwide in warm waters.


Studies have been conducted which demonstrate up to 99% effectiveness at preventing methane production in cattle.


Asparagopsis contains chemicals such as bromoform which are released in digestion, able to interact with stomach micro-organisms to prevent energy wastefully becoming methane.


Let's talk

We Farm Seaweed


We farm a special seaweed at mass-scale to feed the hungry appetites of cows.

Dairy cows are fed seaweed


A small amount of dried seaweed is included in the cow's diet to prevent methane production.

Dairy brands become methane-Free


Dairy brands may market themselves as methane-free, allowing them to further differentiate their product to dairy consumers.
