In this work was investigated the feasibility to use Waste Electrical and Electronic Equipment (WEEE) glasses in construction sector as secondary raw material. WEEE glasses were used in different percentages as a function of the product obtained: 30-40wt% for glaze formulations, about 40wt% for glass-ceramics and 5wt% in brick bodies. The laboratory and industrial scale up results demonstrated that it is possible to produce a glazed tile with a glaze containing fluorescent lamps glass instead of commercial ceramic frits. Glass-ceramics composed by nepheline ((Na,K) AlSiO 4), akermanite (Ca 2Mg(Si 2O 7)) and celsian (BaAl 2Si 2O 8) were obtained at low temperature and short time (T = 900°C and t = 60 min) with panel glass as component. Besides, small amounts of panel glass were added in brick bodies because this glass is suitable as fluxing agent only at high temperatures; at brick manufacturing temperatures (around 1000°C), the glass viscosity does not enough contribute to the sintering process.
