Hot air rises, and for an Australian company aiming to neutralise the burps of billions of livestock across the globe, investors are hoping its share price will too.

Sea Forest, an Australian livestock feed additive manufacturer using seaweed to slash livestock's methane emissions, listed on the Australian Securities Exchange on Wednesday, November 26.

The organisation's SeaFeed supplement, made from the Australian seaweed asparagopsis, has been proven to reduce methane emissions by up to 80 per cent, while recent studies also found the additive helped livestock grow faster.

After securing a European distribution deal and partnerships to help launch in markets in Japan and Brazil, the public offering will fund Sea Forest's path to profitability after years of extensive research investment, founder and managing director Sam Elsom said.
