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 25, 2023At the recent joint 21st AfWASA International Congress and Exhibition and 7th Conference on Faecal Sludge Management (FSM7), Eawag signed a Memorandum of Understanding agreement with the African Water and Sanitation Association. The two conferences took place under one roof in Abidjan, Ivory Coast.

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 25, 2024At night or during cold winter days, lake water cools faster near the shore than in the middle of the lake. This creates a current that connects the shallow shore region with the deeper part of the lake. An international team led by Eawag researchers were able to show for the first time that this horizontal circulation transports gases such as oxygen and methane.

January 22, 2024Empa Director Tanja Zimmermann and Eawag Director Martin Ackermann want to provide answers to the current climate crisis with new initiatives and ambitious goals.

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 12, 2023Field studies by Eawag researcher David Janssen in southern Greenland show that the heavy metals in the rivers are largely of natural origin, and that the influence of mining and agriculture is negligible, at least during the period observed.

December 8, 2023Legionella always interact with other organisms. Eawag researchers have characterised microbial communities and analysed their relationship to Legionella.

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.
