In a world threatened by water shortages, there are technologies for transforming wastewater into drinking water. The resulting water is at least as pure as normal tap water. In order to challenge producers and consumers preconceived notions about wastewater, and to acknowledge that wastewater can be part of the solution in the future, Nya Carnegiebryggeriet joined forced with IVL, Swedish Environmental Research Institute, and developed PU:REST – Sweden’s first beer brewed with purified wastewater.
The water used in PU:REST comes from Hammarby Sjöstadsverk, where the water has passed through a long chain of purification stations. After thorough lab testing, the water was delivered to Nya Carnegiebryggeriet in Hammarby Sjöstad, Stockholm, and the brewing team took over. Four weeks later, PU:REST – Sweden’s first beer brewed on wastewater, saw the light of day.
