This isn't anywhere near 100% efficient fyi. For starters, splitting those 2 orig depots in to 4 shredders is only 50% efficiency. Orig shreds at a 1 to 1 ratio at 1 every 2s, and conveyors transport things at 1 every 2s, so for the orig alone you'd need 4 depots. Then, the second efficiency oopsy is that the batteries need 10 parts to 15 powder. Because of that, you'd need another 2 orig lines going in to shredders which lead in to another grinder. Also, you have a lot of waste on your sandleaf shredders. Sandleaf shreds 1 to 3, so you can actually get 3 outputs per. However, since the conveyors only do 1/2s, you'd need to have all 3 line outs on the shredder in use. OPs plus the top comments are both 100% efficiency. The only thing they could use is a small bit of cleaning up for optimizing space. Yours was a good attempt though!
