PYROCHAR main objective is to overcome the scientific and technical barriers keeping small municipalities and Wastewater Treatment Plants (WWTPs) from using thermal treatment (pyrolysis) in their municipal sewage sludge management.


  • Drying and pyrolysis treatments are energy demanding
  • Adaptation of the technology to small plants
  • The reuse of the pyrolysis syngas requires efficient clean-up technology
  • Thermal treatment process is too complex and demands high maintenance
  • Lack of scientific understanding of sludge pyrolysis and syngas behaviour in gas turbine/engine (CHP)
