Water is a completely essential ingredient for beer production.
However, in Singapore, one brewery is taking a greener approach to sourcing the ingredient, using wastewater that, before being treated, contained (amongst other things) the urine of local residents – and now the ingredient may be enjoyed in a can of NEWBrew. This greener approach to sourcing this ingredient is being pioneered in Singapore.
How is recycled wastewater utilized in beer production?
When it involves the beer brewing process, the ingredients that first come to mind are malt, hops and yeast. However, beer production just isn’t possible without one essential ingredient: water. Brewers must fastidiously select the suitable waters to attain the specified yield. For example, to provide strong beer, it is suggested to make use of water with a high mineral content.
Thanks to the treatment of Singapore’s sewage, a brand new, more environmentally friendly approach to brewing beer has been discovered. Since 2003, the NEWater project has been developing a treatment system aimed toward regenerating drinking water for most of the people. The fluid, which in fact also comprises urine, is subjected to a series of purification steps, including microfiltration and ultraviolet disinfection, respectively. In this process, bacteria, viruses and other particles are eliminated.
