I am doing a system expansion of my LCA and one of the products of it is biowaste. I would like to model the following:
biowaste -> compost -> nitrogen fertiliser
I found the following processes in Ecoinvent:
treatment of biowaste, industrial composting | biowaste
nutrient supply from compost | nitrogen fertiliser, as N
However I am struggling to connect these processes to obtain my final product nitrogen fertiliser as there are only elementary flows in the treatment of biowaste, so I don't know how much compost is actually produced with the process. Is there a way to find out?
