November 17, 2021Together with a team of researchers and designers, Kai Udert has designed a toilet system that makes it possible to recycle nutrients from wastewater on-site. As a result, valuable nutrients can be recovered and used as fertilisers so that they no longer end up in lakes and oceans where they do a lot of damage. Now he wants to make the system ready for market together with industry partners.

September 15, 2021Making decisions about what sanitation infrastructure to implement in emergency and humanitarian crises is challenging. Research on how to support this decision-making has led to the online platform: emersan-compendium.org.

June 1, 2021The Zambezi River Basin in southern Africa is a high-quality waterscape. But current rapid development threatens the waters of the Zambezi, particularly its tributaries. The challenge will be to ensure that mitigation measures keep up with population and economic growth to avoid degradation of water quality degradation.

May 28, 2021Treated wastewater can be continuously monitored online with the use of organisms. This gives operators of wastewater treatment plants and discharging industrial companies the ability to respond to acute pollution quickly.

May 26, 2021The shift from fossil to renewable energy sources is essential for climate mitigation but will also significantly reduce the atmospheric input of the nutrients sulphur and selenium into soils. Sustainable solutions are therefore needed to supply intensively used agricultural soils with sufficient nutrients and to ensure a safe and healthy diet for the world's population.  

May 21, 2021An Eawag researcher has helped to develop a new approach to tracking how river water enters the groundwater. In the test area within the Emmental, the flow time within the aquifer has been shown to be much shorter than previously assumed. This has potential consequences during dry spells.

April 29, 2021Their very small size means that rotaviruses are difficult to filter out of water. But these pathogens are among the leading causes of gastrointestinal infections, especially among children in developing countries. Now, a team of researchers from Empa and Eawag has demonstrated an approach that could make rotaviruses easier to remove in the future.

April 15, 2021Never did Jagannath Biswakarma think that a Tweet about one of his academic articles would receive attention from world-leading media outlets. Yet, that is exactly what happened and how his work was promoted internationally.

March 25, 2021In the latest NEST podcast with Peter Richner, Tove Larsen talks about what we flush down the toilet, why problems should be solved at the source and why wastewater doesn't lie.

March 23, 2021Online biomonitoring systems offer the possibility of real-time monitoring of wastewater with organisms and enable wastewater treatment plant operators to react immediately to acute pollution in wastewater. So far, however, very little information is available on the suitability of online biomonitoring systems for such monitoring. An applied project by Eawag, the University of Applied Sciences Northwestern Switzerland and the Oekotoxzentrum is now set to change this.
