Deconstruction
An Introduction for the Cook County Board of Commissioners
March 13, 2012
•Deconstruction • Carefully dismantling a building and salvaging
components for reuse. Results in:– Products for sale (windows, doors, lumber)– Jobs and trained labor force– Improved environmental quality
•Demolition • Destroying a building (or portion), often with
heavy machinery, employing very few and resulting in some recycling, and large amounts of landfill waste.

Construction and Demolition WasteWaste– Construction and demolition material is largest
single category of waste in Cook County– Cook County has 1 remaining landfill – 7 years of
remaining capacity
Demolition– 250,000 homes demolished annually in the US
(2006 EPA figure, before increases due to foreclosure crisis)– Dust from demolition contributes to asthma.
Reuse potential - fixtures, doors, windows, cabinets, lumber, and brick are some of the materials in a typical home that can be reused.
