3 Information regarding the LCA

3.1. Life cycle analysis

The LCA report has been drafted by the Ceramics Technology Institute based on data provided by Levantina on the extraction processes of the marble blocks and subsequent processing into slabs. The data were then entered in GaBi 7.3.0.36 (Win32) [6] for obtaining the different impact values.

The lifecycle analysis (LCA) on which this declaration is based has been conducted according to the ISO 14040 and ISO 14044 standards, and the basic product category rules for construction products included in UN-EN 15804 and the type III enviromental labels standard UNE-EN ISO 14025.

This LCA is of the “cradle-to-gate” type, i.e. it considers the product’s entire stage of manufacturing of the product.

The scope of the study was defined as cradle-to-gate, encompassing only the manufacturing module (extraction and preparation of raw materials, produc-tion of the natural stone slabs and transport between these stages).

This LCA is “cradle-to-gate”, that is to say, it considers the entire product manufacture stage.

3.2. Declared unit

The declared unit has been defined as “1 t natural stone mass”.

Additionally a conversion factor to kg is established of 1 x 10-3 t/kg and a density of 2666 kg/m3. These values are shown on Table 3.

3.3. Allocation and cut-off criteria

In accordance with the PCR – part A − IBU, EPD program Calculation Rules for the Life Cycle Assessment and Requirements on the Project report and PCR – part B – IBU, EPD program, requirements on the EPD for Dimension stone for roof, wall and floor applica-tions, administered by IBU according to construction product category rules EN 15804, whenever it has been possible in processes with multiple inputs and outputs, the causality principle when performing allocations had been used. The LCA report therefore sought to establish the physical relationship between the system’s inputs and outputs and its different

products. When this was not possible, the mass and surface criterion was used.

3.4. Representativeness and quality of data

The most recent stable data from the three product manufacturing plants analyzed and from the raw material extraction plants for the manufacturing process of the analyzed product (data referring to 2015) was used for the study. All included data are less than 10 years old. Furthermore, wherever possible, we have used data referring to the country in which the process in question takes place or, when this was not possible, we applied regional or global data.

The accuracy and precision of the data entered in the databases used (Gabi7.3.0.36; [6]) were assessed by their authors and it was concluded that the degree of uncertainty is acceptable given the objective of the report. Moreover, it was considered that the data collected or calculated by the authors of this study has a low degree of uncertainty, since it refers to factory information supplied and explained in detail by the company.

To ensure the consistency of the data utilized, the Thinkstep Professional database only was used.

3.5. Other calculation rules and hypotheses

The environmental results for the three models, Crema Marfil Coto®, Marrón Emperador and Caliza Capri, pro-cessed in the 3 production plants will be presented in a single EPD grouped together under the name of natural stone as well as individually, as permitted by the grouping criteria of the general Product Category Rules (PCR) (part A) for construction-related products and services of the EPD program administered by IBU and of the PCR (part B) for natural stone for use in general ceilings, walls and floors of the IBU program.


4 System boundaries, scenarios and additional technical information

4.1. Processes that precedes manufacturing (upstream) (A1-A2)

The system’s limits are represented in Figure 4.

The cycle starts with the extraction of a large prism-shaped block, which is then subdivided during a set of successive stages until reaching the final squaring.

The semi-finished blocks obtained from cutting up the prism are cut to the size of the commercial block and cleaned up on all their faces by squaring them with diamond wire. This processing of the blocks makes them ready for transport. The natural stone blocks are then carried from the quarry to the factory in trucks with 22-ton load capacity.

4.2. Manufactuing of the product (A3)

The natural stone blocks brought from the quarry whose shape is not that of a rectangular prism need to be squared before starting the cutting process. To do this, the blocks are cut with diamond wire equipment. The blocks are then sent to be cut into slabs 1.5, 2 and 3 cm thick, employing a steel strap cutting assembly.

Subsequently, in the reinforcement stage, a glass fiber coating is spread on one of the slab surfaces, adhering it by applying a thin resin coating. In some cases the use of film as well as fiber may be required. On the other side of the slab only a thin resin coating is applied, and where it is considered necessary, putty will be used to seal any possible cracks. It should be emphasized that not all slabs are reinforced.

Marble slabs coming from reinforcement or directly from cutting are passed to the polishing line, starting with the calibration process where the slab thickness is adjusted. It will then progress to the processes of puttying (if necessary for repairing the sealing of a crack) and polishing (through the use of abrasives) to obtain the gloss. After curing and drying, a wax coating is applied to prevent scratches during transport.

Once the slabs have passed through all the stages of the production process, they are packaged. The slabs are packed in different ways depending on whether their destination is national or international. This means that slabs with a national destination are secured on the truck by means of straps, but slabs with an inter-national destination are placed on wooden trestles. Once the slabs have been placed on the trestle, they are placed in the containers for transport.
