Each day, a large number of pharmaceuticals, their degradation products, and other micropollutants end up in our wastewater. The concentration of heavy metals, hormones, and antibiotics in the groundwater is therefore increasing strongly impacting our environment.
The toilet paper flushed has a mycelial component that is only reactivated during flushing. The hyphal network is able to metabolise pollutants dissolved in the water on its way through the sewage system. Four different methods and material experiments are used to show how living organisms can be integrated into industrial toilet paper production.
