Fremantle Seaweed is growing the seaweed Asparagopsis that has been proven by the CSIRO led team at FutureFeed to reduce cattle methane emissions by up to 90% when added as a 2% feed additive. Methane is a potent greenhouse gas (28 x more powerful than CO2) with livestock producing 14.5% of global greenhouse gas emissions. Asparagopsis feed supplement is a technology we have available to us right now in the fight against climate change. Further to the reduction of greenhouse gasses is the ability for seaweed to act as a biofilter and clean up our oceans by removing nutrients and preventing ocean acidification.
The challenge will be to grow Asparagopsis seaweed at the scale required to reach the 1.5 billion cows on the planet and currently there is no commercial production. Fortunately, both Asparagopsis species (armata and taxiformus) are endemic to Western Australia and Fremantle Seaweed is undertaking a project to produce a trial crop at our aquaculture lease. We are a company owned and operated by seafarers and our goal is to scale up operations from 100 tonnes to 1 million tonnes over the next 5 years. We have the ability to make a significant impact in the reduction of greenhouse gasses whilst simultaneously cleaning up our oceans.
