Aggregate is the world's number-one nonfuel mineral commodity in terms of both volume and value (Fig. 9.1). During 1998, worldwide, about 20 billion tons of aggregate worth about 120 billion Euros were produced (Wellmer and Becker-Platen, 2002). Worldwide demand is estimated to be rising by 4.7% annually (Bleischwitz and Bahn-Walkowiak, 2006).
