I am working on the process, treatment of used Li-ion battery, hydrometallurgical treatment, in Ecoinvent 3.7.1 and in OpenLCA 1.10.3. I want to assess the global warming potential (GWP) contribution of all the flows in this process.
I have created the product system for the process above and want to conduct the LCIA (Life Cycle Impact Assessment) using ReCiPe 2016 Midpoint (H) to obtain the GWP. After obtaining the LCIA result, how do I aggregate all the GWP contributions from all the upstream processes related to a specific flow?
I performed the LCIA for a similar process, but I copied all the process contributions to GWP from the LCIA result and pasted it in Excel. I am checking the model graph from the product system and in Excel I am using the filter function to search for those processes. It would be more convenient to obtain an aggregate of all the GWP contributions from all the upstream processes related to a specific flow from OpenLCA as there are so many links between the processes in the product system.
Thanks for your help in advance.
