Les Roches – Roussillon: The Largest Chemical Platform in France

Located between Lyon and Valence, between Northern and Southern Europe, the Chemical Platform of Les Roches-Roussillon is characterized by varied types of chemistry (phenols, sulphur, phosphates, methionine, silicon intermediates, etc.) and is served by multimodal infrastructure (motorway, rail, river).


In the middle of Europe 

A strategic geographical location


The Platform is at the heart of the Lyon - Saint-Etienne - Grenoble triangle and near Lyon-Saint-Exupéry International Airport and its high-speed rail station. The Les Roches-Roussillon Platform offers special hospitality conditions to companies seeking a new location in Rhône-Alpes.

The Platform enjoys a strategic location close to the Feyzin refinery. It represents one of the key components of the "Rhône-Alpes Chemistry Valley" that extends from Pierre-Bénite to Roussillon.

Halfway to the universities and research centres of Lyon and Grenoble, the Platform is particularly aimed at chemistry-related companies.


Situated between the communes of Roussillon, le Péage-de-Roussillon, Salaise-sur-Sanne, and Saint-Clair-du-Rhône, it covers 150 hectares of space, and is located about forty minutes from the Lyon metro area and its three high-speed rail stations.


It is located near four other motorways, enabling fast, direct access to Paris and all major European markets. It is also close to two airports (Lyon-Saint-Exupéry and Saint-Etienne).
