Hello!
I am working now on a LCA about the asphalt carbon footprint, inside my assessed activities it is the landfilling. The landfilling is performed if RA it is not recycled and it is considered as a waste. My question is:
Does exist an indicator or a emissions factor that represent the emitted tons of CO2e by each ton of asphalt (or construction demolition waste) disposed or landfilled?

Thanks

Dear RMidence,

There should not be any GHG emissions from landfilled asphalt since the material is inert (no DOC). However, there are emissions when you produce the asphalt.

Please refer to the 2006 IPCC Guidelines volume 5 (Waster) - under industrial waste (e.g. construction and demolition). Industrial solid waste includes waste from construction and demolition, which are mainly inert materials. Only those industrial wastes which contain DOC and fossil carbon should be considered for estimating emissions http://www.ipcc-nggip.iges.or.jp/public/2006gl/vol5.html

For the production part the relevant information is reported under the industrial processes sector, section on asphalt production and use http://www.ipcc-nggip.iges.or.jp/[…]/V3_5_Ch5_Non_Energy_Products.pdf

I hope this is helpful.

Kind regards,
