Development of a Reference Plant for Sewage Sludge Incineration



The EEW Group intends to expand their existing waste-to-energy facilities by adding an incinerator for sewage sludge at several locations. The separate incineration of sewage sludge is a prerequisite for the recovery of phosphor from its ashes, a requirement under the reformed sewage sludge ordinance.

The construction of sludge incinerators at existing waste-to-energy sites allows the harnessing of synergies between both facilities, which makes the operation more economic compared to a green field project.

Engineering services for the technical development of a reference plant for sewage sludge incineration taking into account the plant areas:

  • clarifying sludge receiving department
  • bunker and conveying
  • dryer
  • furnace and boiler
  • flue gas cleaning
  • thermal use
  • installation planning
  • treatment of vapor condensates


  • Selection of available technologies in the field of process engineering
  • Component design calculations
  • Supplier discussions and feasibility studies
  • Creation of value-added analyzes to compare competing methods
  • Compilation of the relevant documents
  • Selection of external speakers
    Documentation and compilation of structural, procedural definition and regulatory strategy
  • Process-related calculations
  • Graphic presentation of the reference plant
  • Documentation of the specifications in report form and in a presentation
  • Cost estimation
  • Compilation of the documents in digital form

Technical Data:

  • 32,500 Mg/a municipal sewage sludge (DM)
