Related to the issue discussed here: https://mods.factorio.com/mod/quality-lib/discussion/68105588dad1696fdf737391
The items added by Quality Lib do not have a recipe associated with them, so the game does not generate a recycling recipe for them. An update for Quality Lib is in the works with a bunch of fixes, and fixing this specific shouldn't be too difficult. I just need to manually create the recycling recipes myself instead of leaving it up to the game to auto-generate them.
If you want to avoid this issue for now, make sure that quality items stay within their logistics chains and never enter your inventory. It's when they enter your inventory that they are converted into the modded items.
