Reducing cattle emissions up to 90 per cent through a feed additive

 

Livestock contribute as much to global greenhouse gas (GHG) emissions as the entire global transportation sector. As a byproduct of their digestion, cattle belch methane, which is 25 times more potent as a heat trapping gas than is carbon dioxide. One cow emits approximately 1 tonne of CO₂-equivalent every year. Synergraze Inc. is developing a feed additive for cattle that is capable of reducing methane emissions from cattle by up to 90 per cent. They are developing a land-based tank facility to produce and process a strain of red algae into a cattle feed additive that nearly eliminates methane emissions from cattle. The project is forecasted to reduce 68,400 tonnes of GHG’s per year. ERA committed $5 million to the $15 million project through its Food, Farming and Forestry Challenge, a $33 million funding competition that supported 17 projects worth a combined value of $107 million.
