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.

June 18, 2021Bacteria from an Indian landfill could help eliminate contaminated chemicals. The focus is on pesticides such as lindane or brominated flame retardants, which accumulate in nature and in food chains. Researchers at Eawag and Empa used these bacteria to generate enzymes that can break down these dangerous chemicals.

June 1, 2021The Zambezi River Basin in southern Africa is a high-quality waterscape. But current rapid development threatens the waters of the Zambezi, particularly its tributaries. The challenge will be to ensure that mitigation measures keep up with population and economic growth to avoid degradation of water quality degradation.
