The EPFL has launched a new Massive Open Online Course (MOOC) in collaboration with Eawag’s Sandec department and the International Committee of the Red Cross (ICRC). The course is designed to shed light on the important role played by Public Health Engineers at times of humanitarian crisis, and how health risks can be mitigated. Read more

A study just published by Eawag scientists shows that gold and silver each amounting to around CHF 1.5 million a year are lost via effluents and sludge from wastewater treatment plants in Switzerland. The concentrations measured do not pose risks to the environment – and recycling would not be economically worthwhile. However, the study also produced surprising findings on other trace elements in wastewater, including rare earth metals such as gadolinium and the heavy metal niobium. Read more

August 25, 2017

Eawag researchers working on the research project “VUNA” have developed a new recycling process with which nutrients in urine can be harvested and used as fertilizer. In order to further their ideology of sustainable handling of water and wastewater and to work out and implement innovative concepts of water and wastewater treatment, the researchers have founded the Spin-off Vuna GmbH.  Read more

July 24, 2017

It has been a year since the research building NEST was inaugurated by Empa and Eawag. Since then, scientists working in the research platform Water Hub have investigated new models and methods to recycle waste water. Experiments for processing and reusing grey water started in June.  Read more
