Miami, Florida

Industrial materials recycling team

Industrial Materials Recycling Team

  • Promotes the reduction, reuse, and recycling of industrial materials

    • Construction and demolition (C&D) materials

    • Coal combustion products (CCPs)

    • Foundry sands

    • Tires

    • Slags

    • Pulp and paper residuals

Why reuse recycle these materials

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.

Reuse/Recycling Can Occur Onsite and Offsite

Consigli s waste management four tier system

Consigli’s Waste Management Four Tier System

  • Tier I: Direct Reuse and Recycling

  • Tier II: Source Separated Materials

  • Tier III: Mixed C&D to Offsite Separation

  • Tier IV: Mixed C&D to Landfills

State programs regulations

State Programs & Regulations

  • Massachusetts ban on disposal before processing

  • California requires 50% diversion from landfills

  • Various states have grants and education programs

Local ordinances

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

Other factors influencing recycling

Other Factors Influencing Recycling

  • Increases in fuel prices

  • Green building initiatives

  • Efforts to reduce GHG emissions

  • General difficulty to site landfills

Not just c d materials

Not Just C&D Materials …


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.

Other industrial materials

Coal fly ash

Iron/steel slag

Foundry sand


Structural material

Masonry material

Many more…

Other Industrial Materials

  • Measure – “What gets tracked gets managed”

  • Explore barriers and how to overcome them

  • Increase awareness

  • Recognize success

Measurement c d materials

Measurement: C&D Materials

Preliminary 2003 draft numbers

  • Will be measuring annually -- need a viable, economically feasible source of data

  • Currently looking at data states collect and publish

Exploring barriers increasing awareness

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
