N2 Applied, a Norwegian technology company based in Oslo, has found a way to stop cow dung from releasing environment-damaging methane gas. It is testing its plasma technology in Europe and on three farms in the UK.
To test the system out, dung from the barn floor was deposited in a pit from where it was moved through the N2 machine. Nitrogen from the air and a blast from a 50-kilowatt plasma torch (similar to lightning) were forced through the dung slurry to lock in both methane and ammonia emissions. This stopped the release of methane into the air. The end product was an odourless brown liquid called NEO or nitrogen enriched organic fertiliser.

Methane is a powerful greenhouse gas. Over a 20-year period, it is 80 times more potent at waring the atmosphere than carbon dioxide.
