  2. 2. DefinitionsDeconstruction•• Carefully dismantling a building and salvaging components for reuse. Results in: – Products for sale (windows, doors, lumber) – Jobs and trained labor force – Improved environmental qualityDemolition•• Destroying a building (or portion), often with heavy machinery, employing very few and resulting in some recycling, and large amounts of landfill waste.
  3. 3. Building Material Reuse Center: ReBuilding Exchange in ChicagoStore open 6 days a week, makingreused materials available to thepublic. Employs 10 FTE’s
  4. 4. 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 capacityDemolition – 250,000 homes demolished annually in the US (2006 EPA figure, before increases due to foreclosure crisis) – Dust from demolition contributes to asthma.
  5. 5. Construction and Demolition WasteReuse potential - fixtures, doors, windows, cabinets, lumber, and brick are some of the materials in a typical home that can be reused. Sample diversion results from pilot Cook County deconstruction, June 2011
