January 18, 2022Eawag researchers investigated this question in two extensive pilot studies at the Furt-Bülach and Glarus wastewater treatment plants. The findings: Granular activated carbon filtration efficiently removes micropollutants, is technically feasible and is an equal alternative to other processes.

January 14, 2022Moritz Gold and Aryeh Feinberg have been awarded the 2021 ETH medals for their outstanding doctoral theses. The topics of the two dissertations were the utilization of organic waste for breeding the larvae of the black soldier fly, and the modelling of atmospheric sulphur and selenium cycles.

January 12, 2022All living organisms that respire have to get rid of electrons. In oxygen-free environments, microorganisms deploy special molecules which act as extracellular electron shuttles to transfer the electrons from cells to minerals. A group of researchers has now discovered what determines the electron transfer efficiency of these “taxi” cars: the energy differences of the transported electrons.

January 4, 2022The honourable Natural Research Society of Zurich has just published its 224th New Year's Bulletin. It is devoted entirely to the eight square kilometre Greifensee, which Eawag is also researching intensively.

December 9, 2021In the "Projet Lac" research project, 35 lakes in the Alpine region were systematically examined for their fish populations for the first time: In Switzerland alone, 106 fish species were detected. With almost 20 percent of all known fish species in Europe, Switzerland is one of the hotspots for fish species diversity. The results are now the basis for measures for sustainable fishing and the protection of this still preserved diversity.

December 8, 2021It makes sense to study land and water habitats together, according to the initial findings of the Blue-Green Biodiversity initiative.

December 7, 2021With around 200 pictures and texts, the new Water Timeline takes you through 200 years of the eventful history of Swiss water protection. It aims to show how shifts towards more sustainable management of natural resources can be shaped. 

December 2, 2021Researchers from 90 scientific institutions worldwide have stated that freshwater biodiversity research and conservation lag far behind the efforts carried out in terrestrial and marine environments. In a new publication in Ecology Letters, they propose a research agenda with 15 priorities aimed at improving research on biodiversity in lakes, rivers, ponds and wetlands. This is urgently needed, as biodiversity loss is taking place much faster in inland waters than on land or in the oceans.

November 29, 2021Eawag scientist Christopher Robinson is one of the main editors of this book on the biological and hydrological characteristics of more than 180 of the highest profile rivers in Europe.

November 26, 2021In the latest episode of the Papers to Practice Podcast, Dorothee Spuhler talks with Charles Niwagaba about his published article on the microbe-associated health risks involved in using faecal sludge in Ugandan agriculture. This is the second part of the podcast series, which she started with Laura Kohler.
