1984 – Single-pressing ceramic tiles: Coem created a new ceramic tile with superior technological specifications, designed and made entirely in-house as regards both the manufacturing facilities and the product itself.

1999 – Ecogres: ceramic porcelain stoneware body made with a very high ratio of recycled material.

2003 – First series made entirely using digital technology.

2006 – Patented a new industrial application (MPS) to transfer the glass metal silkscreen suspension onto the ceramic tile.

2008 – Patented a new industrial application: production and insertion of three-dimensional inserts with differentiated patterns and graphics, placed in a non-repetitive manner on the ceramic tile. (Porcelain stoneware was previously made ​​with surface texture and with repetitive patterns).

2009 – LEED^® – certification of ceramic tiles for their content of recycled materials.

2009 – Registration of the Design of the Nu_Travertine series.

2009 – Deep HD 3D Technology: use of ultra-pure raw materials and ultra high definition digital graphics, penetrating ​​the depth of the ceramic tile, capable of manufacturing a three-dimensional and mirror-polished effect, enabling light to penetrate into the depth of the porcelain stoneware before being reflected back. The DEEP HIGH DEFINITION 3D system created a new dimension in ceramic tiles: depth.

2010/2011 – LEED^® – Certification of ceramic tiles for their content of recycled materials.

2012 – Eco++ – achieved a body made completely of porcelain stoneware using a high percentage of glass waste and fired at lower temperatures compared to traditional stoneware, achieving a 40% reduction in CO₂ emissions during firing in accordance with Ecolabel limits.

2012 – LEED^® – Certification of ceramic tiles for their content of recycled materials.
