[GreenYes] Re: Conversion Factor for Mixed Containers...


Although I hadn't replied on your original post. 200-250 lbs/cu. yd
is what we'd usually use.

You should also look at the source date. I suspect the average
number gets lower over time, as we get better about diverting one of
the heavier streams--paper--leaving higher % of plastic films,
styrofoam, and other lighter streams (although remaining food waste
is literally an 800 lb gorilla 8^) ). At least that's what I'm
seeing happening out here.

I'd also be interested in other's thoughts on the evolution of waste
stream weights.
