The law EGalim adopted in November 2018 has accelerated the substitution of conventional packaging materials by biobased packaging, notably based on poly (lactic acid) (PLA) and cellulose.
The question that arises today is the following: are these bio-sourced materials really less impactful on human health and the environment than conventional non-biodegradable petro-sourced materials?
This project aims to study the environmental and human health impacts of bio-based materials by implementing an innovative strategy to facilitate stakeholders' decision making regarding the choice of alternatives to conventional plastic materials.


To this end, selected commercial packaging materials, based on biopolyesters and/or cellulose, will be studied initially under use conditions and the work will consist of analysing the migration phenomena in various types of foodstuffs (transfer of compounds intentionally added in the formulation of the materials, or unintentionally present-neoformed compounds).
In a second phase, the impact of ageing on the structure and properties of the selected materials and, ultimately, on the environment (particularly the marine environment) and human health (endocrine disruptors) will be studied in depth.


Materials, physical chemistry of polymers, characterisation of biopolymers. Experience in the field of food packaging would be welcome

Work Context

The Laboratoire de Chimie des Polymères Organiques (LCPO) is a joint research unit attached to the CNRS, the University of Bordeaux and the Bordeaux Polytechnic Institute.
The LCPO is made up of 4 research teams and comprises nearly 150 people, including about 50 permanent staff.
The work of the recruited agent will be carried out within team 2, Biopolymers and biosourced materials, a team led by Henri Cramail.
