COMPOSITE SAMPLE
A SOUND ENVIRONMENTAL RESOURCE
Powerlite is manufactured from bottom ash – a byproduct of burning coal in electricity generating power plants.
Concrete blocks manufactured using PowerLite qualify for consideration as recycled content materials ina variety of sustainable building programs. These include the U.S. Green Building Council’s LEED
program and various federal government procurement guidelines.
