Construction & Demolition Brochure

How Does The C&D Machine Work?

Construction and demolition debris requiring little or no processing is separated by a small front-end loader and placed in individual debris boxes by commodity (i.e., metals, wood waste, and bulky material for disposal).

Large or bulky materials are handled with an excavator and deposited in the appropriate debris boxes. The remaining construction and demolition debris is sorted on a customized, mechanical pick line. Materials are loaded onto a feed conveyor with a front-end loader or a grappler. As the construction and demolition debris proceeds along the conveyor, large or bulky materials (wood, metal, plastics) are manually removed and placed in appropriate debris boxes.

Remaining materials (smaller wood and metal) are manually sorted and placed in individual debris boxes by commodity. Residual, non-recyclable waste is containerized after falling from the end of the conveyor and is transported to a landfill.
