It appears it's not possible to see the resulting quantities of disconnected co-products when calculating a product system. So for example, if you have a process for gasoline combustion that you connect to an upstream refinery, you'll get the emissions from the refinery but not the amount of diesel that's co-produced with the gasoline. A result that's perhaps useful if you're just looking at system expansion. Or perhaps you might want to know the quantities to allocate at the system level rather than at the process.
Another use case would be a waste-to-product process, where a waste treatment process has a waste input flow and a product flow output.
As of now, it seems the only way you could get those co-product quantities is to convert them all into waste flows, so that they show up in the Outputs of an inventory result.
A colleague swears that this wasn't always the case - that the quantities for disconnected co-products in the system were shown in inventory results. Was there a change to this at some point?
