18° SIMPOSIO INTERNAZIONALE SULLA GESTIONE DEI RIFIUTI
E SULLA DISCARICA SOSTENIBILE / 11-15 OTTOBRE 2021

Anaerobic waste treatment in the Circular Economy:
basics and technical implementation

THURSDAY 27 MAY 2021 / 10:00 - 13:00 (GMT+2)
Michael Nelles, University of Rostock (DE)





The biogenic share of Municipal Solid Waste (MSW) worldwide is over 50 % and most of it is still landfilled without further pre-treatment. This leads to climate-damaging landfill gas emissions and the polluted leachates result in soil and groundwater contamination. Therefore, the separate collection and recycling of biowaste or at least the treatment of MSW before landfilling are central measures in progressive waste management concepts. Of course, biological processes are also used, whereby the possibilities of anaerobic waste treatment (biogas technology) are increasingly used in addition to composting.




TOPICS THAT WILL BE COVERED:

  • The role of biomass and biowaste in the circular economy, bioeconomy and energy system

  • Quantities and composition of biogenic waste streams
  • Basics of aerobic and anaerobic biological waste treatment
  • Basics of biogas technology
  • Biogas plants in practice
  • Ecological and economic aspects
  • Summary

 


 

Michael Nelles is full professor of Waste Management and Material Flow at the faculty of Agricultural and Environmental Science, University of Rostock, Germany. He is the Scientific Director of the German Biomass Research Centre (DBFZ) in Leipzig and Member of Scientific Advisory Boards for different national and international conferences and journals. He is author of over 300 articles, chapters in books and journals. His research activity is oriented to: fundamental and applied aspects of waste management, with focus on technological, environmental and economic aspects to mechanical, biological and thermal treatment systems of waste and biomass in different recycling and recovery routes.
