Question about input and output flow in Technosphere flows and Biosphere flows.

[OliverLyon]

In terms of the input and output flow in the LCI I constructed. How do I transform that to Technosphere flows and Biosphere flows. Do I keep input as positive values and output as negative values or is there any other way to do it? Can anyone briefly explain this. Thanks a lot.

I also have a question about multiple products and by products in one process. Is there any way I can add an own defined product in the activity?

Hi @OliverLyon I am not sure what exactly you are asking. But you can find the Technosphere and Biosphere flows of an LCA calculation in the LCA results tab. Perhaps it would help you to follow the tutorial first?
