Not bad! What power source are you using to run the recyclers? As far as I can tell from the screenshots this seems to be underground, so it's probably not solar or wind power. Does it use overclocking?
I'm also curious how fast the transport is through the RP2 tubes. I have been using BC pipes and redpower engines to move items in my own factory and it took some tinkering to make the system just barely fast enough to keep up with the BC engines.
RP2 pneumatic tubes are kinda slow. Try Magtubes from RP2 item speed is 20 blocks per second (but requires blutricity).,
Probably he is using geothermal or watermills.
There are many better systems to make a scrap factory. [Lag-free tutorial has a clockless cobblegenerator designed by me]
