Seaweed to cow feed: Why is Sweden building the world’s largest algae factory?
4 per cent of the world’s methane emissions currently come from cattle, which is two times higher than the whole aviation industry put together.
When fed to cows at a daily dose of just 100 grams, the seaweed feed reduces their enteric methane (gas fermented in the intestines of cows, sheep and goats) emissions by up to 80 per cent.
