Internship: Study of Post-consumer Polystyrene
il y a 2 jours
**Internship: Study of post-consumer polystyrene pollutants to improve the recyclability of yogurt cups**
**Keywords**
Analytical chemistry, material science, recycling
**Duration**
6 months, starting from January/February 2025
**Laboratories description**
The “Centre de mise en forme des matériaux” (CEMEF), Mines Paris PSL, Sophia Antipolis, France is a centre focused on research on material science and transformation processes.
The Institute of Chemistry of Nice, Côte d'Azur university, Nice, France is a research institute with multiple research fields including synthesis, characterisation and recycling of polymers.
**Description**
- Context
With a global polystyrene production estimated around 28 million tons per year (2019), this polymer represents a key material for food material packaging mainly. This corresponds to 100000 t/a of PS plastic wastes, which includes 60000 t/a yogurt cups (Citeo - 2023). Despite the implementation of two new recycling facilities (Belgium and Spain) for 2025 to recycle French PS wastes, little information on the contamination of these packaging is available. NIAS (for Non-Intentionally-Added-Substances) correspond to polymer and additive degradation products, as well as contaminants gathered during the life of the object. These NIAS can have a detrimental impact on recycled material’s properties and could be a threat to human health or the environment.
- project
This project aims at studying polystyrene food packaging, gathered from a sorting centre, to analyse their composition and the contaminants they contain. This will help better understand the risks linked to polystyrene recycling and eventually help to improve its recycling.
- Techniques used
Grinding, extraction, GC-MS characterisation, NMR, use of database.
**Required skills**
Level : Master 2 / 3d year engineering school
Skills in analytical chemistry, polymer chemistry and material processing are recommended.
