Scrap recycles into every recipe you currently have unlocked.
Items that have a chance of loss give scrap instead.
No ores, no trees, no rocks, just a recycler and your wits. Good luck!
Had a setup where 4 Recyclers output into the same chest.
Using Even Distribution to start all 4 with the same item at the same time leads to a stack of 4 perishable scrap items being in the same slot. But this still only gives a single scrap result, not 4
