Uses for
Ash
Fly Ash is a non-hazardous
powdery material that is a byproduct of the combustion process at the
Rawhide Energy Station. Most of the fly ash produced
at Rawhide is disposed of in a State of Colorado-approved monofill located
on the plant site.
With
goals of avoiding disposal costs and saving natural resources, Platte
River works to find beneficial
uses for Rawhide fly ash. There
has, historically, been little or no use for Rawhide's fly ash
due to changes in its chemical properties caused by the sulfur dioxide
(SO2) removal process at the plant. Fly ash from coal-fired plants that
do not remove SO2 from their exhaust streams is used in a number of construction
and industrial processes.
During the last few years, Platte River has had success supplying Rawhide
ash to the operator of a liquid waste disposal facility and manufacturers
of architectural block.
When mixed with fly ash, liquid waste is solidified for easy handling
and disposal with minimal hazard to land and ground water. By substituting
Rawhide fly ash for a portion of the cement traditionally
used in their mixes, block makers can significantly reduce production
costs without loss of block strength.
With an eye to the
future, Platte River also works with Colorado State University's Department
of Civil and Environmental Engineering with its research into new beneficial
uses of Rawhide's fly ash.
