Alga Biosciences

Alga Biosciences tackled methane emissions from cattle digestion, which accounts for roughly 14-18% of global greenhouse gas emissions. ​​‌‌‌‌‌‌‌​‌‌​​‌​​​​​​‌‌​‌‌‌​​​‌‌Dairy and beef farmers experienced this problem most acutely—regulatory pressure was mounting while feed costs consumed significant margins, leaving them vulnerable to future carbon pricing. The problem was highly measurable; methane output could be tracked through animal respiration chambers and milk production data, making impact quantifiable. Existing alternatives were limited: farmers could adjust diets marginally or reduce herd sizes, but these approaches sacrificed productivity or profitability. Alga Biosciences proposed adding seaweed-derived compounds to cattle feed to reduce methane production by up to 80%. Early validation came from peer-reviewed research demonstrating methane reduction in controlled trials, combined with immediate interest from major dairy operations facing ESG commitments. Feed companies and agricultural cooperatives began exploring partnerships, signaling genuine market demand beyond environmental enthusiasm—farmers would adopt the solution if it maintained milk yields while reducing costs or meeting sustainability targets.
