Hi, I am very new to conducting LCAs and I would very much appreciate your help! My study looks into biowaste management options (incineration, anaerobic codigestion), and I am using the latest Ecoinvent (v 3.5) dataset in openLCA 1.7.
1. As I am looking purely at the incineration/burning process' impact categories only, is it correct to use Cut-off, and not APOS or consequential modelling?
2. When I click 'create product system' out of the dataset "treatment of biowaste, municipal incineration|biowaste|Cutoff, U", my impact categories do not seem right. For instance, under CML 2001 methods, the global warming impact (GWP 100a) is very slight for large amount of 1kg of biowaste. Am I doing it correctly or should there be other inputs that I missed out?
3. Referring to the same image above, the other bars that are not red indicate the GWP from other processes like quicklime production etc. If I want only the GWP from burning the biowaste, can I ignore these other bars (i.e. only use the red bar)?
Thank you very much!
