In Space Age, all biochambers need fuel which can spoil, so it's common to make an output inserter that only outputs spoilage to a dedicated belt / chest.

Would that be possible to always suggest the spoilage as filter for output inserters of biochambers?

Hmm... we already have suggestions for spoiled inputs and outputs, but not for spoiled fuel.

Adding spoiled fuel shouldn't be too hard to do, will see about it soonish.

Ah , yeah makes sense. I was thinking on having the spoilage filter even when no recipe is set

Yeah. We had filter suggestions for:

• Spoils of input/output
• Incoming fuel
• Burnt fuel

So now I added "spoiled fuel", as an filter suggestion for output.
