6-10% of typical construction waste is gypsum wallboard. When gypsum is not separated it becomes added volume and contamination in the fines which are used for Alternative Daily Cover (ADC) or land filled along with other trash.
Separating wallboard from mixed construction waste requires different procedures than waste that can be successfully recovered from the pick lines. Construction & Demolition waste processing systems typically push up large piles with wheel loaders and load systems with grapples. As a result, boards become crushed and mostly lost to the fines screens. Pre-crushers further reduce recoverable-sized particles from sort lines. Due to construction procedures, loads consisting primarily of wallboard with incidental installation waste such as buckets, caulk tubes and metal studding often arrive in close proximity.
Construction & Demolition Processors, who successfully reclaim high percentages of gypsum board, dump these loads in a separate spot on the tip floor. The processors conduct a manual positive floor sort to recover the wallboard. They then stage it in a bunk or in roll off containers until a tractor trailer load is accumulated.
