The “Recommendation on sewage sludge handling” as part of the Helsinki Convention on the Protection of the Marine Environment of the Baltic Sea Area entered into force in March 2017. It defines the principles for the sustainable handling of sewage sludge in the Baltic Sea region.

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.
