Waste glass as a binder in low carbon cement-based materials

Abstract

The construction sector contributes to the significant consumption of natural resources and the production of large quantities of waste materials. It is a major contributor to greenhouse gases, leading to global warming and climate change mostly due to the production of cement. Globally, waste glass is generated in large quantities but offers opportunities for recycling. In the local scene, it was revealed that the management of glass waste is a continuous challenge. It is often a loss-leader due to the absence of a glass waste recycling plant in Malta which leads to its transportation overseas for its management and recycling to avoid dumping in landfills. Moreover, recycling of glass waste generates a significant carbon footprint due to the high melting point of glass. Furthermore, recycling coloured glass is challenging due to the colour specificity.
