News Decentralised resource recovery from wastewater

December 1, 2023

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.

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.

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.

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.

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 17, 2022No tiger duck and no football club - the formula "yellow-black-grey" refers to the separation of wastewater streams at their source, i.e. at the toilet, washbasin or shower. This opens up new possibilities and saves resources. On the occasion of World Toilet Day on 19 November, a series of Eawag fact sheets shows how this can be done.

September 16, 2022The “Water Wall” developed by Eawag researchers recycles handwashing and toilet flushing water in a closed cycle and can therefore be used in regions with scarce water resources or those without water and wastewater networks. Now the project has been awarded the Mülheim Water Award.

August 4, 202225 years ago, urine-diverting toilets were no more than an idea, challenging the central paradigm of wastewater treatment plants. Since then, however, modular water technologies have become increasingly important. Using a new method, scientists at Eawag have mapped the dynamics of this transition.
