Our Calcium Carbonate comes from marble manufacturing through a natual exsiccation process without addition of other substances. Our product has an extra ecological feature because it comes from the recovery of a by-product: the mud coming from marble slice. We treat this by-product using a special process that we have elaborated and patented and that is unique in the world. That gives to our Calcium Carbonate a surplus in quality and purity. We offer three different kinds of Calcium Carbonate (CaCO3): CRAV 10R RICARB 40R RICARB 90R
