How to Close the Loop of Platinum from Heavy Vehicles Catalytic Converters? Framework to Evaluate the Impact of Several Promising Action Levers

The overall platinum recycling rate from autocatalyst is 50% (less for heavy vehicles). The issue is how to improve the end-of-life recycling rate of Pt & the recovery of CC in Europe? Many qualitative recommendations and opportunities are discussed in the literature but there is a lack of quantitative studies to evaluate the impact of possible solutions. The objectives are; (1) Make an inventory of influence parameters to close-the-loop & link the identified parameters to stakeholders’ action levers (2) Quantify the impact of key actions levers on the CE performance by considering both environmental & economic parameters (3) Propose and test a methodology to do so on an industrial system. The multi tool methodology proposed is made of: (a) Material Flow Analysis (MFA) with STAN (b) Fuzzy Cognitive Mapping (FCM) with Mental Modeler (c) Structural Analysis with MICMAC (d) Scenarios Generation with MORPHOL (d) System Dynamics (SD) with Vensim (e) Looping to report the impact on the value chain and actors’ network.
