Abstract

Municipal solid waste is one of the most pressing environmental problems the world faces. Nowadays, incineration isconsidered to be the most effective technology for treating it. However, after the incineration process, close to 25% of the initial totalmass of waste is ash, which has to be placed of in landfills. Recent trends suggest that further progress in resource efficiency ispossible by turning waste into a resource and thus closing the loop in a circular economy. Fly ash can be utilized as a substitute fornatural resources in construction, as in aggregates or in the manufacture of new materials. In particular, these fly ashes containelements such as Ca, Si and Al, which make it possible for them to be used as a raw material to manufacture binders. In the presentwork, the results obtained from the physicochemical characterization of fly ashes will be presented. The research aims to explorethe feasibility of using this fly ash as raw material in the manufacture of eco-friendly binders.
