A beer from wastewater is produced in Germany to counteract climate change

This beer project undertaken by two Berlin-based water supply companies and the local brewery Herforder was presented within the framework of the International Water Recovery and Recycling Convention.


Berlin is known as a great innovation center, and Germany, with its great beer production culture joins environmental purposes in the face of climate change through innovative methods in the city. Concerned about the importance of this element, the water technology company Xylem together with the Herforder brewery created this wastewater beer called Reuse Brew.

The project consists of producing beer with purified wastewater, as well as simple and clean ingredients such as hops and barley malt. Jan Karl Nielebock, an expert brewer from Xylem, says: “Our Reuse Brew is created according to all the rules of the German brewing art, and contains, in addition to recycled water, the best ingredients that a craft beer needs.”

Premiered at the beginning of June, Reuse Brew was only presented at the Water Recovery and Recycling Conference in Berlin. Its commercialization is not planned and only 1000 bottles – four hectoliters – were produced for promotional purposes. The creation of this beer entails the awareness of the use of water and the importance of recycling it.

Xylem had previously worked on projects to create beer from wastewater in the United States. On the other hand, last summer a Stockholm brewery supported by Carlesberg launched a beer made from recycled sewage water called PU:REST.


Other Recycling Methods for Producing Beer

Not only water, which counts as a vital ingredient and whose estimated use is around 3 liters of water per liter of beer can be reused or recycled. Yeast is a highly recycled element, specifically by commercial breweries.

Unlike artisanal breweries who comparatively produce in small quantities. Mainly this practice is used because they can get vigorous fermentations over and over again, and because it would be prohibitively expensive to buy enough yeast to ferment every batch of commercial size. For their part, artisanal breweries benefit from better production with each yeast transfer after each production.


The German Brewers’ Association’s Opinion

For its part, the German brewers’ association expressed itself through its spokesman Holger Eichele over this subject, who explains that the association is committed to protecting existing resources for brewing. He adds, however, that “the best water is that which does not ask to be cleaned or conditioned, because it is sufficient and of the best natural quality“.
