Unit processes and cumulative results LCI
Posted: 16 Jul 2012 08:56
Hello,
I have developed a rough LCA model with openLCA and have a few questions. I'm still a bit confused between unit processes and cumulative results. Unit processes are used for developing a model. However, after in the inventory of product system only cumulative results are seen (as elementary flows). For example, if I want to know the raw materials composition of my system, are these represented by elementary flows (e.g. resource/ in ground) or...?
Another question, when I develop my own process (inputs represented by various product flows) and I don't create extra cumulative results LCI. Is it OK to do this way?
I hope I was clear enough to explain my issue.
Thanks
