Economic Benefits
Several million tons of CCBs are recycled into useful applications annually in the US. The type of CCBs, their market location, their quality, and the season are all factors that determine the value of CCBs. For instance, concrete quality fly ash lowers the cost of construction and improves the quality of the product. Another example is synthetic gypsum (FGD materials), which can be used in wallboard. Its use circumvents mining and the processing required for natural gypsum.
