Abstract : Legislative frameworks of waste management are impacted by resource management and industrial ecology’s paradigm. Considering this issues through engineering science, social sciences and regional planning, this work focuses on technical, political and spatial dimensions of recovery-recycling chain. It aims at analyzing its regional development, through the example of the treatment of Waste Electrical and Electronic Equipment (WEEE). It reveals how local recycling system contributes to the development of territorial ecology, while focusing on a systemic approach of WEEE recovery and recycling in Midi-Pyrénées (France).This work shows how WEEE’s management interacts with European and French legislative frameworks. Based on a material flow analysis of the recovery-recycling chain, this study shows the strategic issues of the chain’s metabolism which results from the dynamics of the various organizations involved.
