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

[David Jaber <djaber@no.address>]

Christine,

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.
