You could look into Seablock and some of the related mods (iirc Angels and Bob's mod packs) which add some of those sorts of complexities. IIRC some things can require charcoal filters, in which case you have to build the filter frame and filter, get it to the machine that needs it, then recover, replace and regenerate the used filter. Another fun challenge is "feedback", where a later step in a production line produces as waste something you can consume at an earlier stage.
