use of sewage sludge

Two English-language technical guides are now available to countries where modernisation of facilities for waste water treatment and sewage sludge management is imminent, e.g. to comply with EU requirements.

What can be done with the sewage sludge which is generated during waste water treatment? How can valuable materials be recovered and pollutants prevented from entering the environment? The German Federal Environment Ministry (BMUB) invited a Polish delegation on a study tour to promote exchange between the two countries. The group visited exemplary sewage sludge utilisation plants in Germany.
