Abstract
Methods and systems for reclaiming materials from a mixed waste landfill containing coal combustion byproducts (CCBs) are disclosed. The methods and systems can be used to reclaim CCBs from ponds or dry landfills by obtaining mixed waste, crushing the mixed waste to form crushed mixed waste, drying the crushed mixed waste to form dried crushed mixed waste, and combining the dried crushed mixed waste with other compounds to form a blend. The blends can then be incorporated into a cement material, which may be used to form concrete.
