The mask-like accessory was developed by U.K. startup Zelp Ltd., which claims it can reduce methane emissions by more than half. Cargill said Tuesday it expects to start offering the devices to European dairy farmers in 2022. The companies haven't set a price yet, but Zelp says an annual subscription fee may start at about $80 a cow.
