Trappist Monk Brewers Reduce Water Waste In Beer Production

BERKEL-ENSCHOT

The Cistercian monastery on the Dutch-Belgian border is the first brewery in western Europe to construct a plant-based water filtration system that avoids the current waste of seven liters of water for every liter of beer produced. In a large greenhouse, 70 species, including ferns and other sub-tropical plants, sit above bins of waste water that flows through pipes from the brewery. The interaction of the micro-organisms on the plants’ roots and the bacteria in the water purifies it for reuse.
