Reduction of marble waste landfills through the enhancement of CaCO3

The research is aimed to the reduction of amount of marble waste/scraps placed to landfill through the recovery and enhancement of carbonate microfine sawdust, mainly resulting from the sawing and processing of carbonate dimension stones. Going through a regulatory framework in order to make the identification between waste, by-product and end of waste status clearer, the ultimate goal of this research is to identify alternative uses, which have a high added value, rather than landfilling, solution so far preferred but not more well-matched with the concept of sustainable development.
