Singapore brewery makes beer from recycled wastewater... and urine

In Singapore, one brewery is taking a greener approach by using wastewater that, prior to treatment, contained (among other things) the urine of local residents. Cheers!

Hops, malts and yeast are the ingredients you might first think of when it comes to making beer. However, it's impossible to make beer without one essential thing: water. Brewers take care to choose specific waters to obtain their desired result. For example, hard water is preferred for making strong beer.

Beer can be made using processed wastewater.In Singapore, a new and more responsible way to brew beer has been found by filtering wastewater. Since 2003, a program called NEWater has developed a treatment system to renew the water consumed by the population. The liquid, which logically also contains urine, undergoes various purification stages, including microfiltration and ultraviolet disinfection. This process eliminates bacteria, viruses and other particles.
