are commercial varieties of marble, according to the Project Marble Alps , developed by the Center for GeoTechnologies University of Siena for the Tuscan Region (2007). But in the last two decades has established a cross-category: the detritus of marble, the scraps to feed the 'ravaneti', ie landfill mining the Apuan Alps. The debris is pulverized calcium carbonate and thus used for the production of plastics, rubbers, tires, insulation, paint, glue, paper, chemicals, pharmaceuticals, cosmetics and construction. Only for reducing emissions of sulfur oxides in a coal power plant of 1,000 MW will need 50,000 cubic meters per year, 1,500 tons per year in toothpaste sold in Italy, then an indefinite quantity in feed and food . In fact, the interest for the calcium carbonate was born in the early '90s, when he lowered the degree of purity than that used in the food, so outside the bounds of the marble Apuan ended the era of 'Milano to drink' and opened the Apuan to eat.
