Title: Industrial Materials Recycling


1
Industrial Materials Recycling
  • Kimberly Cochran, PhD
  • US EPA Office of Solid Waste
  • AGC Building Division Meeting
  • January 26, 2008
  • Miami, Florida

2
Industrial Materials Recycling Team
  • Promotes the reduction, reuse, and recycling of
    industrial materials
  • Construction and demolition (CD) materials
  • Coal combustion products (CCPs)
  • Foundry sands
  • Tires
  • Slags
  • Pulp and paper residuals

3
Why reuse/recycle these materials?
  • They
  • Can substitute virgin materials AND save energy,
    time, and money
  • Perform as well or better than virgin materials
  • Capture valuable materials that would otherwise
    be lost.
  • Recycling/reusing can mean points for green
    building certification.

4
CD Materials Include
5
Components of CD Waste
  • Wood
  • Engineered Wood
  • Oriented Strand Board (OSW)
  • Plywood
  • Blackboard
  • Dimensional Lumber
  • Treated Wood

6
Wood
  • Markets
  • Boiler Fuel
  • Mulch
  • Engineered boards

7
Portland Cement Concrete
  • Markets
  • Road Base
  • Aggregate

8
Asphalt Concrete
  • Heavily Recycled in New Hot Mix Asphalt

9
Components of CD Materials
  • Gypsum Drywall
  • Markets
  • New Drywall
  • Portland Cement Production
  • Agriculture
  • Construction Material

10
Components of CD Materials
  • Roofing Materials
  • Asphalt Roofing Shingles
  • Asphalt Roofing Felt
  • Recycled into new hot mix asphalt.

11
Components of CD Materials
  • Metals
  • Ferrous
  • Nonferrous
  • Aluminum
  • Copper

12
Components of CD Materials
  • Paper Products
  • Cardboard

13
Reuse/Recycling Can Occur Onsite and Offsite

Consiglis Waste Management Four Tier System
  • Tier I Direct Reuse and Recycling
  • Tier II Source Separated Materials
  • Tier III Mixed CD to Offsite Separation
  • Tier IV Mixed CD to Landfills

22
State Programs Regulations
  • Massachusetts ban on disposal before processing
  • California requires 50 diversion from landfills
  • Various states have grants and education programs

23
Local Ordinances
  • Disposal bans
  • Ban of specific materials from being disposed
  • Waste plan requirement
  • Require all contractors to submit plans on how
    they will reduce disposal when applying for a
    permit
  • Deposit system
  • Fee required when applying for a permit that is
    returned when recycling is proven
  • Salvage period requirements

24
Other Factors Influencing Recycling
  • Increases in fuel prices
  • Green building initiatives
  • Efforts to reduce GHG emissions
  • General difficulty to site landfills

25
Not Just CD Materials
  • Remember
  • It is important to reuse/recycle the waste your
    company generates, but
  • It is also important to use recyclable materials
    from other industries in construction design.

26
Other Industrial Materials
  • Fill
  • Structural material
  • Masonry material
  • Many more
  • Coal fly ash
  • Iron/steel slag
  • Foundry sand

27
Industrial Materials Recycling Team
  • Measure What gets tracked gets managed
  • Explore barriers and how to overcome them
  • Increase awareness
  • Recognize success

28
Measurement CD Materials
Preliminary 2003 draft numbers
Amount Generated (million tons) Recycling Rate
Buildings 160 40
Road Surfaces 170 88
Other sources ? ?
Total ? ?
  • Will be measuring annually -- need a viable,
    economically feasible source of data
  • Currently looking at data states collect and
    publish

29
Exploring Barriers, Increasing Awareness
  • Construction Initiative
  • Encouraging use of industrial materials in
    building or highway construction projects
  • Green Buildings, Highways, and Sustainable Sites
  • Helping develop criteria
  • Promoting industrial materials recycling in green
    structures/sites
  • Promoting coordination between transportation and
    environmental agencies

30
Cement Specifications Concrete Specifications
ASTM C 595,"Standard Specification for Blended Hydraulic Cements. ASTM C 618, "Standard Specification for Fly Ash and Raw or Calcined Natural Pozzolan for Use as a Mineral Admixture in Portland Cement Concrete."
ASTM C 150, "Standard Specification for Portland Cement." ASTM C 311, "Standard Methods of Sampling and Testing Fly Ash and Natural Pozzolans for Use as a Mineral Admixture in Portland Cement Concrete."
AASHTO M 240, "Blended Hydraulic Cements." ASTM C 989, "Ground Granulated Blast-Furnace Slag for Use in Concrete Mortars.
31
Exploring Barriers, Increasing Awareness
  • Asphalt Shingle Recycling Forums
  • Foundry Sand Forum
  • Beneficial Use Summit

32
EPAs Innovative Grants
  • 2005 Grant to CMRA for Tear-Off Asphalt Shingles
    Recycling
  • Update www.shinglerecycling.org website
  • Recycling Asphalt Shingles Best Practices Guide
  • Environmental Issues Associated with Asphalt
    Shingle Recycling

EPAs Partnership with AGC
  • Measurement tool for contractors

How much did my company reused/recycled?
How much did my company SAVE?
42
EPAs Partnership with AGC
  • Recognition
  • Case Studies
  • Others?

43
Things to Think About
  • What obstacles have you encountered?
  • What role does each participant play in
    overcoming the obstacles to industrial materials
    recycling?
  • Contractors
  • Manufacturers
  • States
  • EPA

44
Things to Think About
  • What tools and resources do contractors need to
  • Reuse/recycle materials
  • Use recycled materials

45
Case Studies
  • Recycling/reusing CD materials
  • Using industrial materials
  • Need
  • Amount and types of materials that were
    reused/recycled
  • Size of project
  • Amount of money saved (if available)
  • Obstacles encountered and how they were overcome
