Abstract: The aim of this paper is to propose a simplified method of quantifying the environmental sustainability of raw materials substitution. This method is based on the use of two parameters that account for the energies and emissions involved in the formation of a material. The embodied energy and CO2 footprint are used to define a SUB-RAW index, which is used to compare the environmental performances of selected materials. This method is applied to a real case of stabilized municipal solid waste incineration fly ash using COSMOS (acronym of COlloid...
