• The start-up, Rumin8, has received funding worth $12 million from Breakthrough Energy Ventures, which Gates created in 2015.

How methane is released?

  • The herbivores that chew cud while grazing or browsing are known as ruminant species.
  • Cows, sheep, goats, and buffaloes are examples of ruminants, which have a unique sort of digestive tract that enables them to break down and digest food that other species of animals would not be able to.
  • Ruminant animals have four chambers in their stomachs, one of which, the rumen, allows them to store and ferment partially digested food.
  • Animals vomit this partially digested and fermented food, where they finish the digestive process by chewing it again.

Why is methane a problem?

  • Methane is second only to carbon dioxide in its contribution to global warming since preindustrial times, accounting for 30% of the warming.
  • According to a report by the United Nations Environment Programme, methane has an 80 times more warming potential than carbon dioxide over a 20-year period.
  • Additionally, it is the main cause of the colourless, extremely unpleasant gas known as ground-level ozone, which originates just above the Earth’s surface.
  • A report from 2022 claims that exposure to ground-level ozone may be causing 1 million preventable deaths annually.
