Carbonation of industrial residues for CO2 storage and utilization as a treatment to achieve multiple environmental benefits

摘要

This paper presents and discusses the application of accelerated carbonation of industrial residues in three different contexts (a landfill site, a steel manufacturing plant and a Brownfield site) aimed at storing CO2 and obtaining additional specific environmental objectives, i.e.: the improvement of the leaching behavior of the treated residues, biogas upgrading, the production of aggregates to use in construction applications and in situ remediation of Brownfield sites.
