Sewage Sludge Treatment - Conference

The conference "Sewage Sludge Treatment" provides you with an overview of the current methods as well as future strategies and markets. Learn about innovative methods of sewage sludge treatment as well as the recovery of phosphorus and other resources. The conference also addresses the role of sewage sludge treatment in a Circular Economy.

Sewage sludge - recycling instead of expensive disposal

In light of increasing disposal and transport costs as well as the demand for resource preservation, the treatment of sewage sludge is becoming increasingly important. Next to thermal and agricultural sewage sludge treatment, innovative methods for the recovery of phosphorus are becoming major topics. This development is driven by political decisions which include a foreseeable prohibition of sewage sludge application on EU fields and the classification of phosphorus as limited raw material by the European Commission.

The international conference "Sewage Sludge Treatment" therefore focuses on the following topics:

  • Thermal treatment of sewage sludge
  • Phosphorus recovery with sewage sludge treatment
  • Political developments and the current EU legislation
  • Methods for the (energetic) recovery of sewage sludge
  • Developments of the international markets
