February 21, 2023Wastewater treatment plants can do more than just wastewater treatment. In the future, they should also recover resources. One approach that researchers at Eawag are pursuing is the conversion of the organic carbon contained in wastewater into bioplastics with the help of bacteria.

February 16, 2023A new “Theory of Change” shows which psychological factors influence the use of decentralised water treatment technologies and which measures can support their introduction.

January 26, 2023Where do the toxic metals come from at the bottom of Lake Zurich near Horn Richterswil? With analyses of sediment cores, researchers at Eawag were able to solve the mystery.

January 23, 2023Too much nitrogen enters many water bodies. The anammox process co-developed by Eawag can contribute to reducing outputs from wastewater treatment plants.

January 10, 2023Eawag researcher and EPFL professor, Urs von Gunten has been awarded a prize for outstanding services by the journal Environmental Science and Technology (ES&T).

December 13, 2022The Aqua Urbanica symposium, co-organised by Eawag, explored the question of what is needed to implement the sponge city concept. With the help of this concept, cities should be able to mitigate the consequences of climate change.

December 6, 2022Currently, the first Swiss wastewater treatment plants are being upgraded with an additional treatment stage for the removal of micropollutants using granulated activated carbon (GAC), including the WWTP at Muri. Eawag provided technical support for the design of the installation and is also investigating unresolved issues.

November 24, 2022Together with the Canton of St. Gallen, Eawag has been investigating the impact of the expansion of the wastewater treatment plant at Flawil to include a stage for the removal of micropollutants on water quality in the River Glatt. Initial results now show a very positive picture.

November 22, 2022New technologies in the water sector can contribute to the flexible and sustainable development of urban water management and the sustainable utilisation of water as a resource. In a recent article in the journal Aqua & Gas, a team of researchers from the aquatic research institute Eawag shows what opportunities and risks are associated with this.

November 21, 2022Eawag researchers Wenzel Gruber and Urs Schönenberger have won this year's Otto Jaag Water Protection Prize for their dissertations. Reducing emissions of the climate-damaging nitrous oxide from wastewater treatment plants and reducing the leaching of pesticides from drainage systems are the topics.
