Stoneware tiles made also using glass from cathode ray tubes
Not all waste they can become the objects they were again, and then they change destination. This is the case with the cathode ray tube that, if on the threshold of the first millennium it was still used for new cathode ray tubes, in recent years it is no longer useful for the production of flat screens and risks landfill disposal. That is why it has been studied to use this particular type of glass for the production of floor tiles.
The idea of ReMedia - the Consortium that has been dealing with the eco-sustainable management of technological waste throughout Italy since 2006 - was to find an “intelligent” and practical use for discarded cathode ray tubes. It was born like this Glass Plus, a project promoted by the Consortium to identify an innovative solution in the recycling of glass cathode tube (CRT) panel and reinsert it in the production cycle of a ceramic body used for the production of tiles containing up to 20% of CRT glass.
The resulting benefits concern various aspects: if on the one hand the recovery and recycling targets envisaged by European legislation are guaranteed, CO₂ emissions are reduced by 81% during the extraction and transport of raw materials and significantly reduced energy consumption, from on the other hand, the resulting ceramic products contribute to obtaining credits LEED (Leadership in Energy and Environmental Design), the prestigious sustainability certification on buildings.
Recycling of glass from cathode ray tubes starts with the collection of monitor is televisions old generation; the separation of the cathode ray tube from the plastic and metal parts and the grinding of the glass follow; the fourth phase is the insertion of the glass, suitably treated, in a ceramic mixture, replacing traditional raw materials. The final product is one porcelain stoneware tile LEED compliant.
