The Michigan State University has developed a technology which separates the elements in cow manure to make water and fertiliser.
The technology, which has been under development for ten years, can currently convert 378 litres of manure into 189 litres of water safe enough to feed livestock, and could greatly help farmers cope with drought.
It is also able to extract ammonia and carbon to be made into fertilisers, and can capture the harmful methane gasses found in manure.
The technology will be commercially available to farmers later this year.
