News - Current Eawag contributions to the Sustainable Development Goals (SDGs)

August 22, 2024Microorganisms in biofilms in rivers can break down harmful substances. Some are also able to degrade biocides, including the insect repellent diethyltoluamide (DEET) - or so it is thought. Researchers at the aquatic research institute Eawag have now discovered that DEET is degraded better when the proportion of treated wastewater in the water is high. They attribute this to specific enzymes that occur primarily where wastewater treatment plants return the water to the aquatic environment. However, the enzymes involved are not straightforward to predict.

August 13, 2024Cities need to become more sustainable and use their water resources more efficiently. Managing water in small-scale cycles is one possible solution. A new white paper shows how this can be achieved.

June 13, 2024An Eawag project is investigating how borehole thermal energy storage (BTES) affects the surrounding soil, the groundwater and the microorganisms living in it.

September 14, 2023At today's Eawag Info Day, the Aquatic Research Institute outlined the steps that need to be taken to achieve the Sustainable Development Goals (SDGs).

February 27, 2023Where is there still untapped potential in the use of water bodies for energy generation and what are the associated risks for water systems?

November 17, 2022No tiger duck and no football club - the formula "yellow-black-grey" refers to the separation of wastewater streams at their source, i.e. at the toilet, washbasin or shower. This opens up new possibilities and saves resources. On the occasion of World Toilet Day on 19 November, a series of Eawag fact sheets shows how this can be done.

June 16, 2022It is no secret that climate change has a serious impact on the quality and ecology of aquatic environments. Researchers at Eawag have revealed that human responses to climate change are just as impactful on our water systems – for example, in the areas of agriculture and hydropower.

June 9, 2022Eawag’s research is usually reported on in scientific papers and media articles. Rather unusual, however, is the form of a comic. Illustrator Celine Künzle took a close-up look at Eawag’s research with faeces and recorded her impressions in the recently-published comic report.

June 2, 2022Dominik Scheibler has been Eawag’s Environmental representative since 2021. On the occasion of Environmental Day on June 5, he tells us where Eawag stands in the field of the environment and energy, what the coronavirus could change and what the next milestones are, for example in the context of renewable heat supply.

March 29, 2022Artificial floods mimick natural flows to mobilise and transport sediment downstream, reshape the river and reinstate important habitats for native aquatic insects and fish. Improved outcomes can occur when these artificial floods converge with natural flows and sediment delivery from unregulated tributary streams further down the valley.

March 1, 2022The use of lake and river water to generate heat and cold is constantly increasing. The potential is enormous. Nevertheless, negative impacts on aquatic ecosystems must be avoided. A fact sheet from Eawag lists the key points in this regard.

September 30, 2021Although the consequences of climate change are becoming more and more visible and tangible, the transition to climate-friendly energy systems is only proceeding slowly. In a field experiment, Eawag and the University of Groningen (NL) investigated what kind of measures could be used to better promote innovations such as heat pumps.

September 9, 2021An Eawag study has shown that it makes good sense to recover domestic energy, for example from warm shower water. The study refutes concerns that this form of heat utilisation could have a negative impact on waste water treatment plants. In fact, utilising the energy closer to its source reduces energy losses in the waste-water system.

July 8, 2021Eawag’s practice-oriented courses (known as PEAK) provide training for professionals. Isabelle Schläppi of the PEAK Office looks back over a year marked by the COVID-19 pandemic.
