Production of innovative and sustainable ceramic tiles in several formats (100×100 mm; 250×250 mm). These products fulfill the standard requirements, in particular EN 14411 (“Ceramic tiles: Definitions, classification, characteristics, evaluation of conformity and marking”). The laboratory prototypes are sintered at temperatures about 200°C lower than a traditional porcelain stoneware, allowing an energy save of 10% at least. Physical-mechanical performances are still rather good: low water absorption (<0.5 wt%) and high flexural strength (>60 MPa).
Laboratory prototypes (100×100 mm) obtained with 99% of recycled materials.
Industrial prototype (250×250 mm) fired in a laboratory furnace.
