3 COMPANY DESCRIPTION PRODUCT DESCRIPTION SAVEMA S.p.A. is a working company in the natural stone business since 1975, located in Pietrasanta (LU), and in these thirty years of activity has acquired a position of international leading company as far as production activity is concerned, workmanship and marketing of marbles, granites and other ornamental stones. SAVEMA S.p. has currently an organic of around 100 employees among executives, employees and workers and has its own establishment in Pietrasanta (Lucca), legal and administrative headquarter of the company. The analyzed product is 1 m 2 of manufactured granite of varying thickness (from 1 to 6 cm and massive pieces/mouldings, of average thickness 14 cm). CHEMICAL COMPOSITION % OF TOTAL SILICA (SiO 2 ) 72% ALUMINIUM OXIDE (Al 2 O 3 ) 14,40 % POTASSIUM OXIDE (K 2 O) 4,10 % SODIUM OXIDE (Na 2 O) 3,70 % CALCIUM OXIDE (CaO) 1,80 % IRON OXIDE (FeO) 1,70 % IRON OXIDE (Fe 2 O 3 ) 1,20 % MAGNESIUM OXIDE (MgO) < 1 % TITANIUM DIOXIDE (TiO 2 ) < 0,50 % MANGANOUS OXIDE (P 2 O 5 ) < 0,50 % PHOSPHORUS PENTOXIDE (MnO) < 0,50 % The final product may turn out in slabs of various sizes (width and length) processed on surface according to clients request (polished, honed, flamed, etc. 3/9

4 SYSTEM SCOPE Here below is the process flow. The phase of extraction happens in quarries in Italy, Africa, Europe, Asia, South and North America. The process of phases A3 is done in SAVEMA S.p.a factory in Pietrasanta, or external companies, however located in Italy. The phase of packing and shipment is also done in Savema S.p.a. factory located in Pietrasanta. The productive process calls for the fabrication of a co-product, identified with the term «rough» slabs, that is sold prior to phase A3/4 Cutting of slabs and finishing of cut pieces. All impacts associated to the co-products were not considered in the impact s assessment of the final product. All impacts associated with water treatment and disposal of production have been considered. The impacts of the distribution of the product to the end customer were not considered. UPSTREAM CORE PROCESS DOWNSTREAM A1 QUARRY OPERATION A3/1 SAWING OF BLOCKS A3/2 SLABS PREPARATION A3/3 SLABS SURFACE PROCESS A3/4 CUTTING OF SLABS AND FINISHING OF CUT PIECES A3/5 PACKING AND SHIPMENT OF FINISHED PRODUCTS FINAL CUSTOMERS A2 RAW MATERIAL TRANSPORT PHASE A3/1 SAWING OF BLOCKS In this phase granite blocks are sawed by diamond wire, in slabs of different thickness and sizes. PHASE A3/3 SLABS SURFACE PROCESS The slabs are finished on surface by honing, polishing, flaming, water jet, ecc. processing, using polishing, abrasives, oxygen, gas, water pressure. PHASE A3/4 CUTTING OF SLABS AND FINISHING OF CUT PIECES Slabs are cut and finished to obtain the requested pieces by the final customer PHASE A3/2 SLABS PREPARATION The slabs previously slabbed, if necessary, are submitted to a process of resin/net in back to strengthen and to facilitate the subsequent phases of processing. PHASE A3/5 PACKING AND SHIPMENT OF FINISHED PRODUCTS The finished product, of granite in various sizes, is packed utilizing wood and plastics. Therefore being shipped to the final client. 4/9

5 THE ANALYSIS SYSTEM SCOPE QUALITY DATA : The data used for the environmental impact assessment of the A2 ed A3 phases are: -specific data collected at SAVEMA S.p.A site and referred to the year 2016 for the core activities (consumption, distances etc) -Selected generic data for almost all ECO-INVENT processes used for the LCA model. -Proxy data contribute to the final impacts is less than 5% CUT-OFF CRITERIA As raw material has been considered granite, all energy consumption are included with the exception of the energy used for the processing of resin in the respect of X = Included in the analysis ; MNA= Module not assessed ALLOCATION RULES The allocation rules used, in accordance with the provisions of EN 15804, are specific for each material and the criteria used is that which is identified as the most relevant to the type of work performed. Allocation has been made even for the co-product, using the same criteria as that used for the finished product. The allocation criteria used were: - time required to perform the processing (elettricity, water); - criterion of allocation for mass (oil, wood, plastics); - criterion of allocation for worked surface (LPG, oxygen). the cut-off rule provided by the reference PCR. Not included are materials of which the total weight does not exceed 5% of the total of the items input weight. Some accessory materials were considered as significant during the various processing stages. The total of the considered materials exceeds 99% of the materials used in the manufacturing process.

The impacts are aggregated for the A1-A3 phases, as required by the reference PCR. The environmental performances are calculated on the weight unit, in particular on the basis of the weighted average density of different types of raw materials (2.845 kg/m3).

8 DIFFERENCES ON 2015 OF ENVIRONMENTAL PERFORMANCES Compared to 2015, the environmental impacts of page 6 decrease for the smaller thicknesses (1 to 3 cm), while the larger thicknesses increase their value, with the exception of 6 cm. Regard the use of energy impacts, there has been an increase for all thicknesses. The changes in environmental performance are due to the following considerations: From 2015 to 2016 the production processes and the machinaries not changed at all, therefore the variations in environmental performances (positive or negative) are linked to the mix of processed materials and the production processes, which changes from one year to another based on the needs of the market. As natural products, there are hundreds of varieties with chemicalphysical characteristics, even from one type to another of materials of the same class; these chemical-physical characteristics determine the easy capability or not of processing the material (by the different degree of hardness). the quantity of raw material from non-eu countries, in particularly from Africa, Brazil and India, has increased by about 20% in this aspect increase the impact connected with the transportation of raw materials. Therefore: Considering the same surface to be processed (polishing, polishing, etc.), a very hard material with a thickness of 3 cm requires more time (and therefore more energy, more water, more consumables, etc.) compared to a less hard material (also of greater thickness); in the same way, the sawing of a block of hard material of similar or smaller size than a block of less hard material requires almost always more time (and therefore more energy, more water, more consumables, etc.); The cut phase of a 3 cm thick sheet of hard material may take longer (and therefore more energy, more water, more consumables, etc.) than cutting a slab of less hard material even greater. To conclude, the variability of the mix of processed materials and of the of the production processes (parameters linked both to the trend in demand) every year are the basis of the variation of environmental performance of the various classes of materials and above all are the cause of the lack of correlation (direct or reverse) between thickness and environmental performance. 8/9
