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

ials 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.

ials Not Just C&D 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.
