Workshop: How to achieve climate neutrality in landfilling
Chair / Presidente: Marco Ritzkowski (DE)
Landfills are major contributors of greenhouse gas (GHG) emissions. Diffuse emissions of methane gases are making a contribution to climate change. Moreover, waste handling (collection, transport, placement and compaction) and operation of the equipment for gas and leachate collection and treatment are causing further GHG emissions, whereas further indirect emissions are caused by the transport of construction materials. Minimizing these emissions is an important task which should be amended by additional efforts to substitute CO2 emissions by the generation of renewable energy from and on the landfill sites. The aim is to achieve climate neutral landfills over their entire lifetimes.
The intention of the workshop is to demonstrate and discuss options for GHG emissions reduction in (all) different phases of the landfill lifetime and to evaluate the possibility of achieving a concept for climate neutral landfills in future.
Introductory lectures:
M. Ritzkowski (DE)
Demonstration of possibilities for GHG emissions reduction in connection with landfills
R. Stegmann (DE)
Examples of specific GHG emission reductions, both direct and indirect, during the landfill lifetime
Discussion (main topics):
Climate neutrality in landfilling: What are the main requirements and what are the biggest challenges?
Could a new IWWG TG on “Climate neutrality in landfilling” come up with a substantial contribution and eventually contribute towards the ongoing regulatory process on European level?
