When the lunch bell rings across Lyon Métropole, children unwrap sandwiches in reusable containers, sip from glass bottles, and eat off durable plates—plastic cutlery and packaging are nowhere to be seen. This quiet revolution in school cafeterias and public canteens spans 58 municipalities, where single-use plastics have vanished from public catering not by chance, but by contract. Since embedding binding environmental criteria into procurement agreements, Lyon Métropole has proven that eliminating disposable plastics at scale is not only possible but sustainable—four years on, the shift is permanent, and suppliers have fully adapted.
This transformation matters because public procurement wields enormous influence. In the EU, public authorities spend over €2 trillion annually—around 14% of GDP—and much of that flows into food services. When cities demand plastic-free supply chains, they don’t just clean up lunch trays—they reshape markets. Lyon Métropole, home to nearly 1.5 million people, leveraged this power decisively. By requiring suppliers to deliver food without single-use plastics, they turned policy into practice, creating a blueprint that other regions can adopt immediately.
The change was driven by collaboration. With support from Zero Waste France and as part of the Elevating Reuse In Cities (ERIC) project, Lyon Métropole designed procurement templates that make plastic-free catering a contractual obligation, not a suggestion. Suppliers now deliver meals in reusable or returnable packaging, and disposable items made of plastic are strictly prohibited. Crucially, the transition wasn’t punitive—authorities worked with vendors to find alternatives, ensuring feasibility without compromising hygiene or efficiency. Today, the system runs smoothly, with no rollback in sight.
The impact extends beyond waste bins. According to Zero Waste Europe, which documented the case, Lyon Métropole’s approach demonstrates that systemic change is achievable when public institutions lead with clear rules and long-term commitment. The model is now available as a case study in both English and French, lowering the barrier for cities across Europe and beyond. From Barcelona to Berlin, local governments looking to cut plastic waste can now copy and adapt a proven framework—no pilot programs or trial periods needed.
As plastic pollution continues to choke oceans and overwhelm landfills, Lyon Métropole offers a rare beacon: a solution that works, at scale, right now. The message is clear—cities don’t need to wait for national laws or new technologies. With the power of procurement, they can redesign consumption one meal at a time.
