10 June 2021, Hessen, Darmstadt: Susanne Lackner, Professor of Wastewater Management at TU Darmstadt and head of the "Abwa-SARS" project, takes part in a photo session in her office. In wastewater, the development of the Corona pandemic can be reliably predicted. The TU Darmstadt is one of only two reference laboratories for the sequencing of wastewater samples in Europe. The laboratory has analysed samples from about 50 wastewater treatment plants from all over Europe and coordinates the two Hessian pilot projects in Frankfurt and Wiesbaden.
