Submission + - Australian 'super seaweed' supplement to reduce cattle gas emissions (abc.net.au)
SpamSlapper writes: A company commercialising a CSIRO-developed, seaweed feed product, which slashes the amount of greenhouse gases cattle burp and fart into the atmosphere, has won a $1 million international prize for its work reshaping the food system.
Methane emissions from livestock make up around 15 per cent of global greenhouse gas emissions, and one cow produces on average as much gas emission as one car.
"As a greenhouse gas, methane is about 28 times more potent in terms of global warming potential than carbon dioxide and lasts much longer in the atmosphere," the CSIRO said on its website.
Future Feed director and CSIRO scientist Michael Battaglia said that when added to cattle feed, the product, which contains Australian 'super seaweed' Asparagopsis, virtually eliminated methane from the animals' bodily emissions.
"We know that just a handful [of the product] per animal per day, or 0.2 per cent of their diet can virtually eliminate 99.9 per cent of methane," Dr Battaglia said.
