  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.
