Célia Rennesson is a French entrepreneur, Knight in the National Order of Merit, and a graduate of Paris-Dauphine University in industrial economics. After working at a strategy consulting firm and then at an outdoor advertising group as the Head of Innovation, she decided to leave her position to focus on a new project. In 2016, she co-founded the professional association Réseau Vrac, which brings together companies in the bulk sales sector. In 2023, she facilitated the merger with the national and Île-de-France consignment associations to create Réseau Vrac et Réemploi. She now leads an organization that unites nearly 500 companies in the bulk and packaging reuse sector (including product suppliers, solution providers, and distributors) and manages an operational team of 13 people. Her goal is to develop this future-oriented industrial sector by highlighting the ecological and economic benefits it offers: sustainability in production and consumption methods, national sovereignty, and the creation of local jobs that cannot be relocated.
