You have two fairly simple options here. One is to divert the cobblestone coming from your tesseract before it even reaches your ME system (I see you already have a diamond pipe there which could be used for precisely that purpose, if the tesseract is fairly close to the recyclers); or you could just send everything into the ME system and pull out the cobblestone afterwards.
Should you opt for the latter option (which seems sensible, seeing as you've already got several thousand cobblestone stored), there are a few ways to go about it. The simplest would be to put an ME Export Bus (basic is fine, or precision if the basic one isn't fast enough) on each of your recyclers, configure all of them to export cobblestone, and connect them to your network.
Alternatively, you could place one ME Interface somewhere up near your recyclers, configure it to stock a bunch of cobblestone, and use pipes from another mod to get it into the recyclers. Protip: Buildcraft diamond pipes can act like insertion pipes. If you run a line of diamond pipes across the top of your recyclers, and configure each one to direct cobblestone downward
and leave all the other slots blank, anything that comes through the pipe will go into the recycler if it will fit, or into the next pipe if it won't. You could put another ME Interface at the other end to catch any overflow.
Finally, a bit off topic, are those combustion engines you're using to pull scrap out of the recyclers? You won't need nearly that kind of power unless you've got a ridiculous number of overclocker upgrades. If they're each producing less than one scrap per second, redstone engines will suffice.
actually i might have misunderstood that first picture. Is that glass fiber cable above the recyclers?
I think the recyclers are the ones on top. The machines in the bottom row look like Mass Fabricators, and the cable is an IC2 power cable.
