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

October 31, 2024A new publication by Eawag shows that co-cultures of different microalgae are more resistant to pests than monocultures.

February 29, 2024The United Nations Environment Programme (UNEP) is including Eawag as a non-state partner of the Climate and Clean Air Coalition (CCAC).

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.

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 24, 2022New research findings, and a resulting fact sheet, provide insights into the problematic spread of the invasive quagga mussel in Switzerland. The authors of the fact sheet are concerned that the aggressive spread of this mussel species will have a substantial detrimental effect on lake ecosystems.

February 17, 2022Often overlooked until now: symbioses could be a driving force for the emergence of biodiversity. A case where bacteria live in aphids shows that this can even have practical implications for biological pest control.

November 19, 2021Rising temperatures, invasive species and other factors have changed the composition of species in Lake Constance over the last century. Researchers are trying to understand how this could have happened and what it means for the lake.

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.

September 15, 2021Making decisions about what sanitation infrastructure to implement in emergency and humanitarian crises is challenging. Research on how to support this decision-making has led to the online platform: emersan-compendium.org.

June 9, 2021With the latest analytical methods, potentially toxic substances can be detected even at very low concentrations. However, the aim of research is not merely to document such contamination but also to understand how it occurs in streams and groundwater, and to propose mitigation measures.
