Construction and Demolition

Construction and demolition (C&D) debris consists of the waste generated during construction, renovation, and demolition projects. Waste is generated every time a building, road, or bridge is constructed, remodeled, or demolished. C&D waste often contains bulky, heavy materials, including concrete, wood, asphalt, gypsum, metals, bricks and plastics.C&D debris also includes salvaged building components such as doors, windows, and plumbing fixtures. The majority of C&D waste (approximately 92 percent) comes from building demolition and renovation, and the remainder comes from new construction.

There are multiple factors to be aware of before, during, and after C&D:


Commercial Recycling for Construction

Mercury — The EPA has created a fact sheet called Before You Tear it Down, Get the Mercury Out. This collection of information concerns demolition processes and Mercury. It can be very useful when renovating or when demolition plans are ahead of you to ensure that you will be safe and free of potential mercury exposure.

Reclaiming Old Wood — There are a number of businesses in Montana that use wood from C&D for recycling and repurposing.
