Train comes in, dumps its load. That heads to main recyclers which sort into storage and excess is dumped onto quality line. Quality line is up north, next pic.
Line 1 is the next recycling loop I set up early. It was originally overflow for the main one, but then I converted it to quality. The * section is a "just in case" storage line. It holds another chest's worth of whatever of the main recycled materials.
Line 2 is the overflow from line 1 and also the overflow from main storage. There are requesters that only work over 10k of an item. This is also where I can dump custom items.
Line 3 is trash. It's intent is to void things, but I'll take any quality items I get.
