Agriculture giant Cargill will start selling the masks, putting support behind experimental technology that could help industry cut greenhouse gas emissions
Tackling methane emissions from livestock is one of the most critical — and most difficult — climate issues for meat and dairy companies that are under increasing pressure to clean up their supply chains.

Some 95 per cent of methane released by cows comes out as burps and through the nose. The gas traps 80 times more heat than carbon dioxide in its first 25 years in the atmosphere. Zelp’s wearables, placed above cows’ mouths, act a bit like the catalytic converter on a car. A set of fans powered by solar-charged batteries sucks up the burps and traps them in a chamber with a methane-absorbing filter.
