May 30, 2023Trainees from Eawag’s analytical and training laboratory assist in the analysis of a wide variety of water samples. A prominent example is the National River Monitoring and Survey Programme (NADUF). In a video, we take a look behind the scenes of the laboratory and show its role for the NADUF programme.

May 23, 2023On Saturday, 20 May, the 18th Biennale of Architecture in Venice opened its doors. In the German pavilion, which focuses on building in existing contexts and the recycling economy, also the Nutrient Harvester developed at Eawag is demonstrated. It processes the urine from two on-site dry separation toilets into fertiliser.

January 18, 2024To coincide with the World Economic Forum (WEF) in Davos, the ETH Domain invited 50 dignitaries from the political, research and business spheres, to Davos and presented highlights from its current research. Eawag demonstrated how its work has successfully paved the way for advanced wastewater treatment.

December 1, 2023A team of seven current and former Eawag researchers will receive the Swiss Chemical Society’s Sandmeyer Prize in 2024 for the development of advanced wastewater treatment for the degradation of micropollutants using ozone. And the most amazing thing is: Just about 15 years have passed between basic research and large-scale technical implementation. This incredible timetable was only possible thanks to the wealth of knowledge already available at Eawag and the fact that interdisciplinary collaboration is a matter of course at the Swiss aquatic research institute.

November 30, 2023This research project explores vermifiltration as an alternative method for wastewater treatment. The aim is to fill knowledge gaps.

Defining and implementing policy measures to improve the condition of bodies of water are challenging tasks. The two platforms help to close gaps in knowledge (Photo: Karin Stäheli, Eawag).

October 19, 2023The mandate for the “Water Quality” and “Process Engineering Micropollutants” platforms supported by Eawag, FOEN and VSA has been extended by an additional four years.

September 14, 2023At today's Eawag Info Day, the Aquatic Research Institute outlined the steps that need to be taken to achieve the Sustainable Development Goals (SDGs).

August 17, 2023The combined sewer system is a great achievement. But the discharge of diluted wastewater into central sewage treatment plants is approaching its limits.

July 14, 2023Barbara Jeanne “BJ” Ward received the ETH Medal for her doctoral thesis on predicting the dewatering capacity of faecal sludge in mid-July. The medal honours excellent master and doctoral theses at ETH Zurich each year.
