News Decentralised resource recovery from wastewater

January 12, 2026A new study provides precise data on the origin of plastic in the sea. It could be key to reducing this pollution in a targeted way.

November 18, 2025An Eawag toolbox provides an overview of technologies for decentralised sanitation systems, their respective advantages and examples of built systems.

November 18, 2024During ETH Day on 16 November 2024, environmental engineer Valentin Faust was awarded the Otto-Jaag Water Protection Prize for his doctoral thesis. His work provides important insights about the production of fertiliser from human urine.

October 17, 2024With climate change, hot and dry summers are becoming more frequent, causing water shortages in some regions of Switzerland. Reusing treated wastewater could help to solve this problem. This has been demonstrated by an Eawag team on behalf of the FOEN and some cantons. The researchers also explain what still needs to be done to put the option into practice.

August 13, 2024Cities need to become more sustainable and use their water resources more efficiently. Managing water in small-scale cycles is one possible solution. A new white paper shows how this can be achieved.

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.

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.

April 20, 2023In urban India, rising water scarcity and increasing pressure on water supply utilities have prompted the use of treated wastewater as an alternative source. A study of Eawag together with Indian partners explains how the use of sensors and automated chlorination can improve microbial water quality in on-site water reuse systems for increased user safety.
