Recycling Water To Make Beer
Rainmaker has partnered with local Rotterdam-based brewery Stadshaven Brouwerij to create a circular water management system to be used in the creation of their beer. Brewing 2 million liters of beer each year results in large amounts of wastewater which this system transforms back into fresh water using the residual heat from the brewery as thermal energy. The result is clean, drinkable water that is ready to be used again in the beer production process.
The trial began in July 2021 at the brand new brewery – the 2nd largest craft brewery in the Netherlands – and includes a Water-to-Water (WW) system at the heart of the brewery’s setup. With a ratio of 4 liters of water to make 1 liter of beer1, the unique ability to reclaim the wastewater and recycle it back into the brewing process not only provides cost savings to the brewery but also an incredible amount of water conservation as well.
Dedicated To Sustainability
Stadshaven Browerij is a unique brewery that is completely dedicated to sustainability in every aspect of their business. As such, our WW system fits perfectly into their philosophy of building the circular economy of the future. This project has also drawn the attention of AB Inbev who has shown interest in setting up a pilot project in their brewery in Leuven, Belgium.
