Francesco Colangelo is a Full Professor of Innovative Materials for Civil Engineering and the director of the master’s course in Safety Engineering in the Department of Engineering at Parthenope University of Naples, Italy. His main research areas include recycling of waste materials in concrete and geo-environmental and civil applications, treatment of MSWI fly ash, application of lifecycle assessment methodology to various processes for preparing innovative building materials, evaluation of the durability of mortars and concrete, stabilization and solidification of hazardous wastes, and synthesis of geopolymeric eco-sustainable materials based on industrial waste. He has extensive consultancy experience in the treatment and recycling of solid waste, remediation of old landfills, and resource recovery plants. He has served as the principal investigator for numerous research projects in collaboration with public and private companies. Since 2012, he has been a senior member of RILEM.Raffaele Cioffi has a degree in Chemical Engineering from the University of Naples Federico II. He is Professor of Materials Science and Technology and Materials Engineering at the University of Naples “Parthenope, Naples, Italy. He has been the Head of the Department of Technology and the director of the Research Quality Centre of the University of Naples "Parthenope". He has been the director of the Sustainable Development Engineering Laboratory of the Department of Technology, the president of the Teaching Board for the Industrial Engineering Course, and he is the coordinator of the Technical and Scientific Committee for the Master Course in Safety Engineering of the University of Naples " Parthenope". He is the vice-president of the Italian Association on Materials Engineering (AIMAT). Ilenia Farina is an Assistant Professor in Materials Science and Engineering in the Department of Engineering at Parthenope University of Naples, Italy. She received a DPhil in Energy Science and Engineering from the same university. Her main research activities focus on the stabilization and solidification of hazardous industrial solid wastes, soils, and sediments; the development of energy-saving blended cements, concrete, and geopolymer materials made with coal fly ash, blast furnace slag, MSWI ashes, and other industrial by-products; the inertization of industrial and asbestos-containing wastes and sediments through mechanochemical treatments, with subsequent reuse of the resulting products as building materials; and life cycle assessment (LCA) of production processes for eco-compatible construction materials. She is responsible for several research projects in collaboration with public and private companies.
