Abstract(s)

Nowadays the volume of generated wastes is reaching critical levels, which associated with the depletion of raw materials, shows that a paradigm shift is mandatory. The possibility of using waste materials as partial replacement of raw materials emerges as an opportunity to mitigate the environmental impact of wastes, while reducing the pressure exerted on the Earth’s natural resources. In this work, a local and unexplored waste material coming from the recycling of end-of-life fluorescent lamps (glass wastes) was successfully incorporated in geopolymers production. Glass wastes were used, without any treatment, a source of amorphous silica to partially replace metakaolin.
