Gypsum is hauled away by sheet rock installers. The service is offered as a package based on the square footage of the structure. Builders like this because the costs can be agreed upon before the job begins. 9-truck crew is trained to separate recyclables, maximizing the quantity of materials recovered. McGregor has had mixed success with convincing contractors to separate the wastes on-site properly.

Approximately 70 percent went to a processor who makes boiler fuel, and the other 30 percent were used for wafer board or paper production. The program saves builders as much as 25 percent in disposal costs. A potential obstacle is waste haulers' franchise claims to construction site waste. Proximity of a processor minimizes transportation costs and makes recycling more cost-effective. Proximity to a strong market is critical to ensuring the recovery of collected materials.
