Goals and competencies

This lecture aims to present the major classes of materials (with a focus on metallic, ceramic and hard composite classes), their properties and the associated characterizations, with a clear target on various skills required besides dismantling and recycling of various material classes. The program combines theoretical and practical approaches: (i) elemental separation (selective dissolution, precipitation in aqueous/organic solvents) basing on Potential vs pH or Ellingham diagrams, (ii) practical on devices dismantling, recycling and valorisation from case studies (electronic cards in personal computers, separation and valorisation of the constituents of aeronautic composites : carbon fibers –within polymeric matrix, etc…), (iii) a presentation of some innovative processes (hydrothermal, supercritical fluid processes) as an alternative besides incineration for ceramics or composite materials.

Lesson plan:

I. Towards elemental recycling: elemental separation from solution or thermal processes

I.1- State of the art on alternative recycling processes of inorganic materials (incineration, lixiviation, cementation and other supercritical fluid processes as innovative ways for recycling)

I.2- The various reactions (chemical equilibrium) into aqueous solution (acid-base, complexation, precipitation-dissolution and redox processes)

I3- Pyrometallurgy and hydrometallurgy (towards recycling processes)

II. Dismantling

II.1- State of the art: different dismantling processes used in industry

II.2- School-case study

II.3- A focus on the composite materials (the problems of carbon-polymer dismantling and the re-use of the carbon fibers)

III. Practicals (5 meetings * 4h)

Zinc cementation, Magnesie (MgO) purification, Electronic cards dismantling, recycled carbon fibers properties (chemical/mechanical properties)

IV. Toxicology

4 hrs seminar by a toxicologist specialist allows the presentation to the students of the basic notions of the toxicology science with a clear focus as a branch of chemistry in which the study of the adverse effects of chemicals on living organisms will be presented. Harmful effects of chemical, biological and physical agents in biological systems that establish the extent of damage in living organisms will be introduced. The high significance of the relationship between dose and its effects on the exposed organism will also be shown.
