Yes, marble is a sustainable material! Contrary to popular belief, producing a marble slab is much less disturbing than producing an artificial stone slab. Even the artificial stone must be quarried, in addiction oxy resins, which are highly polluting, are used as binders. Lastly, artificial stone (ceramics) is an energy-intensive product, because it must be fired at a very high temperature (500-600 degrees centigrade). Marble, on the other hand, is produced through mechanical transformations: cutting and polishing. Since it is not treated, just as it is created by nature it can be disposed of. Everything is used in marble, from pebbles to dust, there is no unusable marble waste.
