The large amount of waste yearly disposed to landfill, the global impoverishing of natural resources and environment,
the emergency of carbon dioxide emissions, are some of the motivations driving research institutes and industrial
world to move towards sustainable solutions for civil engineering field. Accordingly, the use of sustainable materials
for green buildings construction is an important goal that must be reached in short times.
Sustainable cements can be designed by partially replacing clinker content with non hazardous waste. Indeed,
recycling process can transform waste in secondary raw materials that work as new cement constituents usually
leading to sustainable binders with peculiar environmental resistances. Details of cement manufacturing process and
its effect on the environmental pollution as well as the route that can be carried out to tailor sustainable cements are
reported and discussed.
