True, unless of course each time the pipe is cleaned, the scrapings and screen are saved for later. Probably some waste, but swim has a bowl full of dirty screens and scrapings that'll turn into something.
1) Start with clean pipe and screen (or several pipes and screens)
2) Hit a few times
3) Clean the pipe, save the scrapings and screen
4) Repeat steps 1-3 until fresh rock is gone
5) Expand the dirty screens to remove residue
6) Mix together with scrapings for a pile of residue to be used as desired
Of course it is a lot of work, but probably not much more waste...
