We are happy to announce the first conference on "Environmental biofilms and flocs: matrix composition, properties and applications" to be held at Aalborg University, Aalborg, Denmark, Tuesday– Thursday, 14 – 16 April 2026.

Environmental biofilms and flocs can be found everywhere in nature and engineered systems, yet little is known about the microbes involved and their biofilm-forming capabilities. Improved biofilm control could help address many water and environmental challenges. At the same time, the extracellular polymers found in biofilms/flocs produced in wastewater treatment plants represent a valuable resource with promising applications. We aim to bring together researchers and professionals for three days of sharing and discussing cutting-edge science in the field of environmental biofilms and their extracellular matrix constituents.

This conference is organized in the framework of the REThiNk project, in collaboration with partners from Aalborg University (Denmark), Aarhus University (Denmark), and Delft University of Technology (The Netherlands).
