Abstract

In the industrial practice, the choice and evaluation of strategies of recycling and reuse of solid mineral wastes (thermal process residues, mining and quarrying wastes, construction and demolition wastes) could be based on ecological risk assessment (EcoRA) and life cycle assessment (LCA) studies also because of the substantial lack of regulations. Several methods and approaches of EcoRA and LCA have been developed so far and it is not always evident to consider a pertinent method for each application case. Furthermore, it is even less trivial to combine local and global scale results so to identify the best scenario from different alternatives. After a comprehensive review of recycling and reuse routes of mineral waste and relative legislation, this study addresses these issues by providing a detailed analysis and comparison of global and local scale impact assessment methods used in LCA and EcoRA, and finally an inventory of LCA and EcoRA studies already completed, to serve as a basis for further research.
