Abstract : This paper assesses alternative granular material use as regards ecotoxicity and toxicity. Stockpiling and use in various roads are considered. Leachates datasets of materials and field tests are collected from literature, the study is focused on MSWI BA, RAP and FS. LCIs due to leaching and percolation are built. Corresponding impacts were determined using a mid-point method: the EP TP results exhibit significant differences between the resources in favour of including such impact to LCA for recycling assessment. A model to allocate all the leaching potential to the alternative resource is proposed and discussed for better assessment within LCA framework.
