Descriptif
This course addresses the problem of secondary resources, i.e. recycling and urban mining. It discusses in a technical way the process of chemical extraction of metallic elements from two important streams which are electrical and electronic devices (WEEE) and waste batteries (laptops, cars).
Important aspects of metal recycling and the main thermal (pyrometallurgy) or wet (hydrometallurgy) technologies currently used for the recovery of metals/elements, as well as emerging technologies and industrial risks will be covered as well as life cycle analysis.
The course will be taught simultaneously online and in person at Chimie Paristech (in Paris 5e).

Programme détaillé
WEEE and their chemical content: What are the chemical elements present in WEEE?; How to build a battery?; Is it worth recycling ? How can we get waste ? Brief description of the collection and sorting processes.
• Thermal methods (pyrometallurgy): a little bit of thermodynamics, roasting, purification, refining.
• Solution chemistry (hydrometallurgy) The main concepts of solubility, complexation, precipitation separation, adsorption, extraction, visit of a chemical separation plant
• The state of the art of industrial recycling: Pyrometallurgical processes applied to WEEE; recovery of rare and strategic metals in pyrometallurgical processes; Recycling of lithium batteries by pyrometallurgy compared to hydrometallurgy.
• Emergent recycling methods and responsible recycling: Chemical risks inherent to treatment (heavy metals, toxic volatile compounds, fires); carbon and energy balance of recycling.
