This study is a systematic evaluation of the recycling process of fly ash, from thermal power plants, for the production of glass ceramics (GCs). Using waste materials as substitutes of conventional feed materials during the production of high added value products has a significant environmental potential, in addition to the obvious benefit of raw materials saving. Fly ash and glass cullet waste materials were employed in the fabrication of bulk and porous glass ceramics and small amounts of other additions. Mechanical testing revealed the influence of heating strategy on the products’ strength characteristics. The samples’ toxicity characteristics were determined through a leaching procedure, indicating no reminder toxicity in the bulk GCs and some hazardous remains in the porous samples, with the overall toxicity being reduced by more than 87%. In conclusion and based on the optimal production parameters of the prototype GCs, it can be stipulated with confidence that this type of recycling procedures could be scaled up with minimal effort from lab scale to mass production. © 2015, Editura Cefin.
