This paper contributes to integrate disassembly for recycling in conceptual design. Thus, we first identify DfD tools and model and we show the methodological lack in conceptual design levels. To complete this lack, we propose thereafter a Conceptual Dismantling Model (CDM) composed by tools to represent conceptual data from functional analysis model and End-of-Life (EoL) valorisation constraints: BDS (functional model), main components, mass estimate, materials and valorisation scenarios. An optimal sequence of dismantling is then defined. This sequence represents the objective to be reached by the designers. Finally, we propose a tool for evaluation made up of three indicators: structure, connection and material, also integrating a method of aggregation to analyse the results. Thus, this tool is dedicated to the piloting design project with valorisation EoL conscious.
