Like the idea of the intermediate itself, had set up big production chains for it, however when I started building late game upcycling loops, I noticed that Big electric engine units were not given back upon recycling any of the recipes that use it. Is it possible to fix the recycling recipes?

This mod should solve the problem and rebuild recycling recipes as late as possible https://mods.factorio.com/mod/recycler-recipes-fix this is a bit more elegant than every mod that changes recipes adding its own call for it . I will add it as a dependency soon.
