From April 9 to 12, 2013, the KU Leuven hosted the 4th Edition of the International Conference on Accelerated Carbonation for Environmental and Materials Engineering. ACEME 2013 followed the three successful previous editions held in: London/UK (Jun-2006), Rome/Italy (Oct-2008), and Turku/Finland (Nov-2010). The ACEME conferences aim at promoting research and development activities on accelerated carbonation at an international level, favoring knowledge sharing and critically discussing future development and implementation in the field.
Among the 62 contributions, 14 were selected to be published in this Special Issue of Minerals Engineering. The bulk of the papers report on the reaction kinetics, mineralogical properties and leaching behaviour in various materials that include serpentine (Ghoorah et al.; Maddedu et al.), mining residues (Assima et al.; Bodenan et al.; Meyer et al.), oil shale ash (Uibu et al.), metallurgical slag (Capobianco et al.; Morone et al.) and hydrated cement (Kinoshita et al.; Pizzol et al.). The papers of Bundeleva et al. and Oliver et al. highlight the use of biological catalysts, a rather new development in the field of mineral carbonation. Process conditions and potential applications of carbonated products are discussed in many of the earlier cited papers as well.
