Numerous reusable materials flow into wastewater from our households, industry and businesses to water-treatment plants. Wastewater can yield energy and fresh water use can be reduced by the utilization of treated grey water. As part of a recycling economy it is also desirable to recover nutrients that can be reutilized. At this year’s Eawag Info Day, established and promising technologies for extracting and recycling energy and reusable materials from wastewater in water-treatment plants and households will be discussed. These processes will not only protect natural resources in the future, but also reduce negative effects on people and the environment.
