As of January 1, 2025, the use of plastic containers in communal catering is banned in France, but Montrouge has already adopted this change. With the introduction of stainless steel containers, the municipality eliminated plastic from its school canteens, a decision influenced by concerns over endocrine disruptors. This transition required a complete overhaul of kitchen operations, staff training, and an investment of approximately 250,000 euros, highlighting the commitment to environmental sustainability and public health.
