I was using another recycler before modmash. Interestingly, now it's outputting sludge. I could've been wrong. I do know not all the ingredients were coming out (not 100% of ingredients), which is one reason I wasn't using it.
Your recycler recycles fewer things, the most obvious being the transport boxes. It's not exactly an issue, because another mod is where they're coming from.
Completely unrelated, your mod and another one, don't limit loot to unlocked objects as far as I know (I didn't try the limit loot checkbox - there's no description and I assume it limits it to one stack). I like getting some things like logistic items, but then it's like "oh here's all the post-space-science god stuff..." or items that aren't enabled because they come from a mod that isn't completely active, but they're still in the item list
Edit: I remember something else after checking: there's no module slots, and I don't know if it can be sped up by beacons. The other recyclers have 1 or 2-6 module slots.
