I used to recycle the logs in order to get Scraps to multiply the Fertilizer, but it wasn't reliable enough. It sometimes made 2-3 Scraps and sometimes made 0-1, but it was most likely 1, which wasn't enough to duplicate the Fertilizer every time. I now use an Igneous Extruder to produce cobblestone, which gets recycled. My system works 100% fine now, but it speeds up and slows down according to when Scraps are made.

By the way, can you extract MFR Rubber Wood? I know you can extract the IC2 and RedPower Rubber Wood, but I've never tried MFR. I might go and test that.
