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

November 22, 2022

November 22, 2022New technologies in the water sector can contribute to the flexible and sustainable development of urban water management and the sustainable utilisation of water as a resource. In a recent article in the journal Aqua & Gas, a team of researchers from the aquatic research institute Eawag shows what opportunities and risks are associated with this.

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.

August 24, 2022Of over a thousand lakes studied worldwide, about one in ten shows strange behaviour. In general, there is an increasing tendency for aquatic ecosystems to tip over. The ecological stability of lakes is decreasing, especially in regions with low GDP and large human populations.

August 4, 202225 years ago, urine-diverting toilets were no more than an idea, challenging the central paradigm of wastewater treatment plants. Since then, however, modular water technologies have become increasingly important. Using a new method, scientists at Eawag have mapped the dynamics of this transition.

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.

May 5, 2022Eawag researchers Sabine Hoffmann, Kai Udert and Lisa Deutsch are committed to a sanitation and nutrient transformation. They use an example to explain why a transformation is needed and why collaboration with politicians in particular is a challenge.

May 4, 2022What has been a purification process in wastewater treatment plants for decades can also be used decentrally or semi-centrally as a recycling process for nutrients. Early separation of "solid and liquid" plays a key role here. It allows for flexible solutions in terms of process technology, especially in the treatment of urine. New studies also show that the processes can be used not only for human urine, but also for that of cows or pigs.

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.

January 20, 2022Switzerland has around 800 municipal wastewater treatment plants. A recent study by Eawag researchers reveals the burden these plants place on the climate, and explores how emissions of climate-damaging nitrous oxide can be reduced.

November 17, 2021The separation toilet save! has won the Design Award Switzerland 2021. This is also a milestone for Tove Larsen. She is a member of the Eawag Directorate and has been researching for almost 30 years how the nutrients in wastewater can be recovered in a useful way. In this interview on the occasion of World Toilet Day 2021, she explains how crucial our handling of wastewater is for climate change and for achieving the SDGs sustainability goals.

November 17, 2021Together with a team of researchers and designers, Kai Udert has designed a toilet system that makes it possible to recycle nutrients from wastewater on-site. As a result, valuable nutrients can be recovered and used as fertilisers so that they no longer end up in lakes and oceans where they do a lot of damage. Now he wants to make the system ready for market together with industry partners.

October 14, 2021Heatwaves and heavy local rainfall will increase with climate change, pushing traditional urban drainage systems to their limits. These problems can be addressed using the blue-green infrastructure approach. With careful planning, solutions of this kind can also increase biodiversity and improve the quality of urban life.

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.

May 21, 2021An Eawag researcher has helped to develop a new approach to tracking how river water enters the groundwater. In the test area within the Emmental, the flow time within the aquifer has been shown to be much shorter than previously assumed. This has potential consequences during dry spells.
