We have had great success with use of a comingled service on our project in the Austin, TX region. It especially helped that there was a recycling option for clean (new) drywall scraps and lumber/pallets. That detail enabled us to divert 5 material types in all. The project CWM efforts ultimately exceeded the 75% threshold on a tonnage basis, which was predominately associated with the heavier concrete and wood based recycled materials.
