I think I must be missing something really important about the way Open LCA works. Please help!
I want to use process: 'aluminium product manufacturing, average metal working'. However I find that the total amount of Al input into this process, that is 'aluminium, production mix, at plant' is 0.227kg and the output of 'aluminium product manufacturing, average metal working' is 1kg. There is no other Al input into this process. It is not possible for 0.227kg of Al to be converted to 1kg.
I must be missing something very basic about the way that processes are used. Id really appreciate it if someone could explain why this is.
