Abstract

methane conversion device comprises a reaction chamber; a sensor for detecting the presence of methane; blowing means for directing external gasses into the reaction chamber when the sensor detects the presence of methane above a predetermined threshold; conversion means that are configured to oxidise methane; and positioning means for positioning the device on an animal. The device provides a portable, efficient way to reduce methane emissions directly from livestock.

Claims (20)
