Having recently read biggie's cost optimisation blog, I did the analysis. At minimum cost, the chamber with the input must have a length 1 arm to reach both sides of the debonder. The arm in the chamber with the output has to reach both sides of the bonder. So, no disposal glyph. Well, after trying min cost for a bit I realised that I don't quite have the skill to manage a brick of waste with no track, so I added one. Now I might as well have an arm of length 2 to get more access points. Yay! That solution came in at ~1200 instructions. I named the solution "The waste beckons".

Soon though I was reminded of the existence of the trash glyph. And what do you know, now I can make a solution that loops, and even one that loops twice per product. That is what you see here. I did not try to optimise for instructions much after that, as I'm already happy with it for my first ever tournament submission :D

I am looking forward to seeing some crazy people manage a brick of waste with no track. But if it turns out that it's actually impossible, I am at min cost and am scoring really well!
