Supported by:

Prof. Dr. Roland Pomberger and Ass.Prof. Dr. Renato Sarc:

Both are from Chair of Waste Processing Technology and Waste Management of the Austrian Montanuniversitaet Leoben. Both are internationally recognized experts in scientific fields of waste treatment & management and energy recovery in cement industry. They are Authors of the “Circularity Position Paper on Manufacturing, Quality, Quality Assurance and Co-processing of SRF in Cement Industry” that will be presented in detail during the event

·        For SRF production in a mechanical multistage processing plant, only non-hazardous mixed wastes from municipal, commercial and industrial sectors are used. Next, non-recyclable residues from sorting and splitting plants for separately collected waste like plastics, paper etc. are used.

·        Term “co-processing” comprises industrial processes that simultaneously enable energy recovery and recycling of the mineral content and thereby allow for the replacement of both mineral resources and fossil fuels.

·        Way of feeding fuel into the kiln is very important, as this can have a direct effect on the resulting emissions. There is a technical reason and a legal restriction that restrains the location of the fuel feeding ports in the kiln system.

·        In the kilns for the production of cement clinker, the gas temperatures are high enough (up to 2,000°C) and retention times long enough to destroy organic compounds and reduce the production of dioxins and furans to the minimum possible, which is within the limits of legal regulations and therefore environmentally acceptable.

·        In countries (Austria, Germany, Switzerland, Poland etc.) where high thermal substitution rates are reached in cement industry there are no harmful effects to people & environment documented that are related to SRF utilization


Abstract Keynote Dipl.-Ing. Monika Denner  Umweltbundesamt (Environment Agency Austria)Role of quality concepts in the context of SRF;

  • Sampling, sample preparation, data evaluation and comparison to limit values.
  • End of waste criteria in the context of the Austrian waste incineration ordinance for solid recovered fuels and SRF products.
  • Outlook regarding new projects at TC 300 level.

Doz. Dr. Hanns Moshammer Head of the Department of Environmental Health, Zentrum für Public Health, Medizinische Universität WienProfessor for Environmental Health (Guest lecturer) at the Karakalpak Medical Institute (Nukus, Uzbekistan)

His research interests are with all possible health effects of environmental exposures with a focus on air pollution, climate change, and occupational settings. These research topics are examined through epidemiological methods.

Who do we bring together?

  • We bring together all key strategy actors (ministers, public officials, municipalities, industry associations, waste collection, recycling/ treatment companies, in Europe with an initial focus on Southeastern Europe and Eastern Europe.

How do we bring together?

  • Through closed groups on the online crowd knowledge platform – weTHINK.eu.
  • Through bi-monthly online working group meetings and two bi-annual online conferences.

Why do we bring them together?

  • To regularly exchange, technical operational and strategic know how and best practices on waste and waste management. 
  • To conduct training for service companies and municipalities on water and waste  management.
  • To develop strategy recommendations and position papers to improve  the legal, political and economic environment for successful waste circularity.
  • To develop projects on waste circularity and to implement them.
  • To improve waste circularity in Europe.
