KEY has developed a reputation as experts in the evaluation and design of CCR closure systems.

We have met the challenge of Coal Combustion Residue (CCR) rules by understanding the geotechnical properties of the various landfills and impoundments for the disposal of CCR.

This includes KEY's innovative and patented "Sustainable Habitat" CCR closure system. This design creates a natural setting for wildlife while reducing the borrow material and closure costs.
