An Alternative Source for Construction Aggregates

Construction aggregates are among the most basic of economic drivers.  Aggregates are the second most commonly consumed commodity by modern society; only water is more important to our way of life.  These commodities are responsible for building and maintaining our modern infrastructure including roads, building foundations, hospitals, bridges, pipelines, office buildings, schools and the like.  Without construction aggregates, our communities would quickly become decadent eye sores and all commerce would cease.
