How do Italians deal with marble slurry?

Answer 1

The natural stone processing slurry waste disposal is a major environment hazard for everybody and not only for Italians. Marble is a rich source of Calcium Carbonate which has more than 1,000 uses. The world over ground calcium carbonate requirements besides, exploiting lime stone deposits is also met by pulverizing marble blocks. However, the process slurry does not find gainful utilization any where and is normally discarded many times in blatant violation of environment protection laws. The problem lies with the gravity sedimentation water circulation methods traditionally adopted by the natural stone processing industry. The gravity sedimentation accumulates stone process dust in the system either in the vertical decanter towers or open pits for a long time. The accumulation of slurry mixes up various colors as well as rich and poor CaCO3 content mineral from the stone processed in various production cycles. The solution to this problem lies in making it possible to discard stone process dust as it is generated without letting it accumulate. This solution is now available in the form of "Water & Waste Harness System for Natural Stone Processing" a patented technology.
