Fly ash production in the United States exceeds 70 million tons annually with only 40% beneficially utilized, leaving over 40 million tons of fly ash for disposal. The most significant factor that negatively affects fly ash utilization is unburned carbon. Currently, ASTM limits carbon levels to 6% and most state DOT departments require a maximum of 3% for applications involving the production of concrete. Concrete production is the highest value market for specification grade fly ash.
The national economic impact of fly ash disposal is estimated to exceed $300 million annually which does not include the future value of land affected by disposal activities. These costs to utilities are a significant component to the overall operating budget. The current situation will intensify as utilities adhere to clean air requirements imposed by lawmakers and the EPA.
FlyAshDirect has developed Carbon Blocker, a chemical treatment application that neutralizes the unburned carbon in fly ash. The treatment process allows the concrete producer to utilize fly ash with higher percentages of carbon without any negative side affects. The process can be installed and operated with minimal disturbance to a power plant’s operating environment.
