The project im working on has a "unicycling" bin in which both garbage and recyclables all go into one dumpster to be sorted off site. The cleaning staff come in once a week and bag up the garbage and recycling seperately and throw it all into the one commingled bin. Any ideas on how to measure volume of recyclables vs trash? Also, does all of the waste leaving the building need to be quantified or can we sample something like twice a month? This is my first LEED project and any help would be appreciated.

Cheers
Ryan
