I'm not looking at "I have a waste container full of waste items", sticking a tile accelerator next to it, and letting that waste container clean up faster. I, and I think the others with this concern, are looking at "How do I recover the landscape faster?". Given that it takes many thousands (10's of thousands) of real-life years, I'm pretty sure that Reika's time scale would be in the many months, if not many years, of real time for a constantly loaded area to go clean.
Turning that down, to only several hours of gameplay, instead of several months/years of gameplay, is the goal here. Cleaning up the environment, so that the chunks that are polluted can be reclaimed.
