I've heard that you can convert charcoal into coal by making/disassembling a torch, although this seems like a bug/exploit that may be fixed, and note I haven't tested this yet as I'm not at home.
If this does indeed work, I'd like to automate this if possible, and I was wondering if I could do this with logistic pipes. I was thinking I could set up a crafting pipe to turn sticks and charcoal into torches, and if it's possible uncraft back into coal, so when I request some coal, it would look for sticks and charcoal, create a torch, then disassemble it and give me the coal.
Is it possible to disassemble items with logistics pipes? Or maybe with some other system in FTB?
