Ever thought burps and farts of cattle are posing a danger to our planet Earth? These digestive processes expel methane, a colourless and odourless gas which is approximately 84 times more potent than carbon dioxide when it comes to warming the planet.
There are approximately 1.6 billion cattle on Earth. And one of the biggest sources of Methane gas is cattle such as cows that produce it during digestion, according to a source.
But no worries as an innovative solution to tackle this problem has come along. Zelp, a UK based firm has created a face mask which filters burps of the cows. As per the source, the mask is able to reduce the methane emission up to 60 per cent.
Mask is not the only solution which has been created to curb this methane emission from cattle so far. There have been few other solutions, such as 'feed additives' that stop the methane production in the stomach itself. But this practice is not recommended as it may pose health problems in the cattle.
The mask does not pose this challenge. It does not alter any biological process of the cattle, making it environment friendly. It allows the animals to carry on their digestion process normally and traps the methane gas when it comes out of their mouth while breathing or burping.
The mask is also found to be comfortable for the cows, as they can also be adjusted according to the head size. It is applied to them after they are weaned, usually at 6-8 months of age.
At the tip of the mask, a sensor detects the percentage of methane that is expelled when the cow exhales. When methane levels get too high, the mask channels the gas towards an oxidation mechanism inside, which contains a catalyst that converts methane into CO2 and water, and expels it from the device.
"The technology detects, captures and oxidises methane when it is exhaled by the animals," said Francisco Norris, one of the two brothers who founded the firm. "Around 95 per cent of the cattle's methane emissions come from their nostrils and mouths," Norris added.
Zelp has conducted behavioural trials and observations with institutions in the UK and Argentina, including the Royal Veterinary College, which have indicated that the wearable has no impact on the animal's behaviour and feeding.
