The award is made under the aegis of the Swiss Academies of Arts and Sciences “td-net for Transdisciplinary Research”, in recognition of the project managers’ commitment to transdisciplinarity: as well as integrating environmental, engineering and social scientific research, they sought the cooperation of non-academic partners at an early stage.
The basic idea is simple: urine accounts for only 1% of the total volume of wastewater, but it contains up to 80% of all the nutrients. If it is processed separately, wastewater treatment plants can be reduced in size, water protection can be improved, and nutrients can be recycled. Separate treatment of wastewater streams thus opens up new possibilities, and there are many reasons for adopting urine source separation (“NoMix”) technology on a large scale. This applies in particular to emerging countries such as China, where sewerage and wastewater treatment facilities cannot keep up with the rapid pace of urbanization, and water pollution arising from domestic wastewater has reached devastating levels.
While the Eawag researchers’ approach may sound straightforward, there is no guarantee that it can be implemented in practice: infrastructure that is already in place cannot be transformed overnight; the new toilets still have some defects – pipes may be blocked by urine scale; the sanitary industry as yet sees little commercial potential in the NoMix technology, and the fertilizer produced from urine cannot yet compete with low-cost artificial products. So obstacles remain to be overcome. The prize money from the award is therefore to be used to support further research: if urine is to be treated with the aid of decentralized systems, and nutrients are to recovered in a concentrated form for recycling, what options offer the best prospects of implementation and the lowest environmental impact? For Tove Larsen, who received the award, together with Judit Lienert, at the 2008 Transdisciplinary Conference in Zurich, it is quite clear: “It’s standard practice for garden waste to be separately collected. So surely it should also be possible one day for the six kilograms of concentrated phosphorus produced each year by a family of four to be separately processed.”
Once again, the research will involve a transdisciplinary process. According to co-project manager Judit Lienert, this is one of the pillars on which Eawag’s work has always rested: “Problems can only be solved with the involvement of all stakeholders. That includes authorities, engineering consultants, and industrial partners, as well as consumers.”

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.
Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...
Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.
Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...
Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.
As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...
Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.
With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...
