Subject: [GreenYes] Construction Demolition Waste


Good afternoon.
I'm attempting to calculate, based on the EPA estimate of 3.89 pounds of
waste per square foot, the volume of waste generated from the construction
of projects we designed in the year 2001.  Can someone share a standard
weight to volume ratio applicable to construction demolition waste?
Thanks in advance.
