Yesterday, the Ecotox Centre Eawag-EPFL celebrated its tenth anniversary in the City Hall of Berne. Around 80 guests from politics, administration, science, and practice toasted the successful establishment of the Centre and the milestones achieved over the past 10 years. Read more

Even though the water we’ve used for washing our hands is barely contaminated, it usually disappears down the drain, never to be used again. A newly developed system allows handwashing water to be recycled, thus not only saving water, but also helping to prevent infectious diseases in developing countries. Read more

Species-rich ecosystems are more resistant to disturbances such as droughts, heatwaves or pesticide inputs – that, at least, is the view widely held by scientists and non-scientists alike. In fact, the situation is more complex, as ecologists from Eawag and Zurich University have now discovered. Under certain environmental conditions, increased species diversity can also lead to an ecosystem becoming more unstable. Read more

Global trade is saving water on balance. In principle, this is a good thing. However, the water budget has its dark side – a fact which Eawag researchers have now brought to light. Read more

Mountain rivers swollen by heavy rainfall deposit large amounts of sediment in reservoirs. To prevent the loss of storage capacity, some reservoirs are equipped with bypass tunnels which convey sediment-laden waters to downstream reaches. The fact that such tunnels offer ecological benefits as well as economic advantages was shown, for example, by a study carried out on the Solis reservoir in Graubünden. Read more

When does the poisonous blue alga reach its critical point and how does the lake react to heat waves? In the future, satellite pictures will answer these questions in real time. This is demonstrated by an Eawag researcher’s new dataset.  Read more

Research in low- and middle-income countries is an important component of Eawag’s mission. The Eawag Partnership Programme (EPP) was developed to strengthen research and research ties with students and academic institutions in the Global South. 10 years and over 80 fellows from 28 different countries later, EPP celebrates the successful building of bridges and transfer of scientific knowledge.

Dealing with wastewater right where it is being produced, instead of in central treatment plants, can be more flexible and economical depending on the location. In Switzerland, however, there are very few such decentralised wastewater treatment plants – although, as Eawag researchers have established, there is a surprisingly strong market potential for them.  Read more

In the future, astronauts on long missions in space will have to take care of their own farming. But will that even work? An unusual experiment by Eawag researcher was designed to find some of the answers. Read more
