Life Cycle Analysis of Innovative Cement-Based Materials Using Stone Waste: State of the Art and Opportunities for Apricena Marmettola

The construction sector is one of the most polluting, due to emissions, resource consumption and waste production. In particular, the environmental impact of cement production and stone processing waste is a significant challenge for the sector. The growing focus on sustainability has encouraged the development of innovative materials, reducing environmental impact and waste. In particular, stone waste can be changed into secondary raw materials for cementitious composites, promoting circular economy. The aim of this research is to establish how the integration of stone waste into cementitious composites can mitigate the environmental impact, by analysing the contributions in the literature that use Life Cycle Assessment analyses for these products. The methodology involves screening contributions on various scientific databases such as Scopus, Google Scholar, ScienceDirect, using appropriate keywords. The aim is to assess the environmental benefits of using this waste. By comparing the chemical-physical characteristics of the analysed stone waste with characteristics of marmettola of Apricena, it is possible to deduce that the marmettola can also bring similar environmental benefits, due to comparable parameters with examined stone waste. The adoption of this approach promotes the transition to a circular economy, helping the reduction of environmental impact and the recovery of waste materials.
