Aurin – Fertilisers from urine (Photo: Peter Penicka, Eawag)
June 28, 2018

Aurin 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. Read more

The 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.

Payment 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. Read more

Ultrafiltration is one of the techniques currently used for disinfecting water – viruses and bacteria are reliably retained by a membrane with extremely small pores. For more than ten years, Eawag has successfully been carrying out research to determine how this method can function using the effect of gravity on water instead of high pressure, cleaning and chemicals. These new discoveries are being applied in increasing numbers of ways. In addition to decentralised drinking water purification, Eawag is now researching uses in areas such as greywater recycling and pre-treatment of seawater for desalination. Read more

There is a wealth of energy and nutrients in wastewater. New processes enable the recovery of these resources from wastewater and sewage sludge, with the goal of redefining the function of the wastewater-treatment plants. Formerly energy users, they will become energy producers and the source of valuable fertilizer. This new technology has convinced the Swiss Climate Cent Foundation. It is contributing financial support to the construction of the new installation in the ARA Altenrhein. Read more

This April, Sandec and its partners hosted two national workshops on small-scale sanitation – one in New Delhi, India and one in Kathmandu, Nepal. The aim of the workshops was to discuss the results of two years of field research with participants from government, utilities, academia, donors, the private sector and NGOs. Read more

Monitoring the effects of chemicals on environmental systems with many species has always been a challenge. On behalf of the Federal Office for the Environment (FOEN), Eawag and the Ecotox Centre-EPFL investigated how the regulation of genes in fish and in single fish cells allow scientists to deduce water quality and fish health.

In 2017, 68 cities (mostly in Europe) again took part in a large-scale project measuring drug levels in wastewater. The results for 2017 were published today by the European Monitoring Centre for Drugs and Drug Addiction (EMCDDA).  Read more

Heavy rainfall can cause flash floods in urban areas. While data from flood events is required to model such phenomena, water levels and discharges are not routinely measured above ground. Eawag now plans to make use of widely available images and videos to estimate these values. Read more

When a person wearing a bright-orange protective suit and carrying a laptop climbs out of a sewer shaft, it could well be an employee of the Swiss Federal Institute of Aquatic Science and Technology (Eawag). Especially if this happens in Fehraltorf. Since 2016, Eawag has been constructing an internationally unique net of sensors that document water circulation in residential areas. Read more
