  of C & D debris
   – 48% (65 million tons / year) from demolition
   – 44% (60 million tons / year) from renovation
   – 8% (11 million tons / year) from construction
• 3500 facilities in the U.S. that process C&D materials
• Metals are most easily recyclable, steel recycling rate is
  about 85% (18.2 million tons out of 21.4 tons recovered)
Cost Comparison Case Study – Riverdale
Village Housing Development, Maryland
• Deconstruction of 2,000 sq. ft. homes
• Estimated Demolition Costs averaged $3.50 –
  5.00 per square foot (total cost $7,000 –
  10,000)
• Final deconstruction cost $13,500
• Sale of salvaged materials was estimated to
  offset final deconstruction costs by $3,000 to
  4,500
• Final Cost of Deconstruction $9,000 – 11,000
• 192 cubic yards of material was diverted
  from disposal
Advantages and Disadvantages of C&D Recycling

• Produces less waste            • More costly than
• Reduces need for new             demolition
  materials                      • Requires more skilled
• Creates business and             labor to process materials
  jobs                           • More time required
• Recovered Materials can
  be donated to charities,
  resulting in a tax write off
