Conversion of organic waste into valuable products is becoming more widespread, particularly in low- and middle-income countries. The treatment of waste by larvae of the black soldier fly (BSF) has especially raised much attention in recent years.  Despite these advances, a significant need existed for guidelines on how to set up and operate a commercially viable treatment facility. The Black Soldier Fly Biowaste Processing: A Step-by-Step Guide published in July 2017 summarises the results of ten years of research and development in this field at Eawag and imparts valuable know-how through practical advice and instructions.

Will global warming force a shift in Biel’s drinking water intake? What caused the sudden turbidity of the water supply in the winter of 2009? Eawag has come up with answers to these and other questions for Energy Service Biel, and in the process, new questions have also emerged. Read more

Bastian Etter checks the quality of the stabilised urine, from which fertilizer will be made.
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

Arsenic-contaminated groundwater used as drinking water or for irrigation may threaten the health of 50 to 60 million people in Pakistan. This is shown by an Eawag-led study – co-financed by SDC – in which data from 1200 groundwater samples was analysed and combined with geological and hydrological parameters to generate a hazard map.

The emergence of new technologies requires conditions tailored to specific industrial sectors. Social scientists at Eawag have developed a conceptual framework describing the relevant innovation drivers. This should make it possible to identify factors hindering innovation and to design industry‑specific support programmes.  Read more

Central Switzerland is shaped by Lake Lucerne, which offers not only rich landscape diversity but also habitats for numerous animal species. As part of the Swiss-wide “Projet Lac” study, the lake’s fish fauna was surveyed for the first time using standardized quantitative methods – producing some surprising findings. Read more

Surface temperatures in Lake Geneva on 1.7.2017: while in Geneva and on the southwest shore near Nyon, temperatures below 10 degrees were recorded, in Évian swimmers were enjoying 22 to 23-degree waters. (Source:
July 13, 2017

If the wind blows away the warm surface waters of a lake, cold water flows in from the depths. As a result of this effect the temperature in Lake Geneva recently sank to 8 degrees. A project led by Eawag and EPFL had predicted this cooling event. Read more
