July 5, 2018Small hydropower plants are often constructed on alpine streams, where they may have adverse impacts on sensitive ecosystems. Little is known, however, about the particular effects of individual plants, or the cumulative effects of multiple plants within the same river system. The current state of knowledge has now been reviewed in a study by Eawag researchers. 

July 4, 2018Janet Hering will take up her fourth term as Director of Eawag in 2019. Today, the Federal Council re-elected her based on the recommendation of the ETH Board. One of Janet Hering's important goals is that Eawag can integrate and synthesize knowledge from a wide variety of areas and thus make it useful in practice. 

June 28, 2018Aurin is now authorized by the Federal Office for Agriculture to be used as a fertiliser for every type of plant. Valuable nutrients from human urine are processed into high-quality liquid fertiliser — the upshot of Eawag’s “VUNA” research project. The Eawag spinoff of the same name as the project is now forging ahead with its urine recycling model.

June 20, 2018Antibiotic resistance is widespread in bacteria spores and preserved for years, as shown by experiments at Eawag and the University of Neuchâtel.

June 19, 2018Nanomaterials consist of tiny particles of different composition. They are used, for example, in textiles and can enter aquatic systems directly from the factory, while being worn or disposed of. For years, research groups at Eawag have been investigating the effects of artificially manufactured nanoparticles on human beings and the environment. Their preliminary conclusion: nanoparticles have a reputation worse than they deserve.

June 15, 2018The CENTAUR sewer control system has been recognized as the ‘Most Innovative New Technology of the Year’ at the 2018 Water Industry Awards in England. CENTAUR stands for ‘Cost Effective Neural Technique for Alleviation of Urban Flood Risk’ and is funded by the European Union’s Horizon 2020 programme. Eawag researchers were part of this project.

June 5, 2018Biological processes in rivers and brooks emit CO2, partly as a result of decaying plant litter that is deposited in the watercourses from surrounding land. Flowing water thus contributes more to the natural carbon cycle than would a terrestrial ecosystem covering the same area. Up until now, global carbon measures have only taken account of rivers that flow continuously. But about half of the world’s river networks consist of streams that are only periodically flooded. Their CO2 turnover has now been examined for the first time by 94 research institutes from all over the world, among them Eawag and the University of Zurich.

June 1, 2018Southerly countries are rich in genetic resources. The companies that exploit this natural treasure commercially are very often from the northern, developed world, however. The Nagoya Protocol was created in order to ensure fair use of genetic resources and appropriate compensation. 

May 28, 2018Microorganisms that live in symbiosis can sabotage biological methods of pest control by protecting their host from attackers, and host organisms can even pass on these beneficial “passengers” to their offspring. This phenomenon is one which has been paid little attention to date, but thanks to new research findings measures can now be taken to counteract it.

May 24, 2018Payment via mobile, replacement parts made on a 3D-printer, error messages via NFC-tag – Eawag doctoral student Caroline Saul has found some remarkable innovations in companies that market container toilets in developing countries. She sees great potential in making such technologies more widely available.
