I'm relatively new to LCA and ecoinvent so it could be that I put this question wrong.
Anyhow, I'm interested in the LCIA from waste treatment operations. Take for example the dataset:
"treatment of aluminium scrap, new, at refiner"Reference product: aluminium, cast alloy [kg]Location: RERSystem model: Allocation, cut-off by classification
If I look at the LCIA information - do I get the environmental impact of this dataset alone, i.e. the impact from the process from "aluminium scrap, post-consumer, prepared for melting" to "aluminium, cast alloy"? And if I want to find the environmental impact from the sorting process, then I have to look at the LCIA from that dataset? Have I understood it corect?
One of the reasons why I am asking is because I have thought that the LCIA represents the cumulative effects, i.e. account for all the upstreams processes as well. I know that a "zero burden" aproach is used for waste in ecoinvent but I'm wondering if the LCIA of the dataset described above - "treatment of aluminium scrap" also accounts for upstream processes such as sorting and collection of the aluminium waste?
