I am a new user of openLCA and I need help with the modelling of my analysis. I am also a beginner of LCA, and I'm learning to use the tool.
I don't understand how to outline the system that I have to study, especially how to separate flows and processes.
In my attempt I indicated as reference flow 1 ton of product, while production process I created a process where I indicated all inputs and outputs. And the problem is here... How do I do now to join the second part of the system, namely the use of the product? And then how I insert the part of recycling of the used product (waste)? (the system becomes a closed recycling)
Below you can see a rough outline of my system, I apologize for its simplicity but I write from a phone and I haven't with me the file of my flowchart.
I hope you can help me. Thanks to anyone who answer me.
Have a nice day,
Eli
