December 15, 2022Work is currently underway in Montreal at the UN Biodiversity Conference (COP 15) to negotiate a framework agreement to preserve biodiversity. In addition to pesticides, nutrients and plastic waste, certain other chemicals ought to be restricted in their production and use, or replaced by less problematic substances, according to a recommendation by a group of scientists, including an environmental toxicologist from Eawag.

December 6, 2022Currently, the first Swiss wastewater treatment plants are being upgraded with an additional treatment stage for the removal of micropollutants using granulated activated carbon (GAC), including the WWTP at Muri. Eawag provided technical support for the design of the installation and is also investigating unresolved issues.
