Le Drive tout nu, a zero-waste grocery service founded in 2018 in Toulouse by Salomé Géraud and Pierre Géraud-Liria, has gained recognition for its innovative approach to reducing single-use packaging. The company was awarded the "Coup de cœur" prize by students from AgroParisTech during the 9th edition of the Grand Prix de la Marque Engagée in 2026, having previously won in the start-up category at the same event. Le Drive tout nu operates by providing products in reusable jars or fabric bags, eliminating the need for customers to bring their own containers. When returned, customers receive a 10-cent credit to their account. The company claims to have more than 12,000 customers, over 300 suppliers, and has avoided more than 4 million single-use packaging items since its inception. The company is expanding beyond its own sales points by introducing "Corners tout nu" in traditional supermarkets. After Carrefour, four such corners were announced in Intermarché stores at the beginning of 2026. This strategy aims to bring reuse options to consumers where they already shop, rather than requiring them to change stores. The preliminary selection committee of the Grand Prix noted the potential for this approach to "expand the impact beyond its own stores" and highlighted the development of a real infrastructure around the deposit system. A funding round of 7 million euros was announced in 2025 to support the expansion of the network, the development of the corners in large-scale retail, and the industrialization of the deposit system. The stated goal is to open 25 new sales points by 2027. Pierre Géraud-Liria, co-founder of Le Drive tout nu, emphasized that the generalization of zero waste depends not only on environmental convictions but also on price competitiveness. The company aims to offer prices 3 to 5 percent lower than those of national brands, though this claim is not independently verified. To achieve this, the company is industrializing its operations, moving from small-scale processing to a larger infrastructure. A new 2,300 m² site was launched to process returned containers, which are then washed, refilled, and returned to the supply chain. This represents a significant expansion from the initial 16 m² space. The company's long-term projections include 64 million euros in revenue by 2030 and the production of 14 million jars by that time. However, the preliminary selection committee of the Grand Prix noted that the "reproducibility" and "viability at a very large scale" of the model still need to be demonstrated, with some results relying on projections. The challenge remains to prove that the model can work at this scale while maintaining low prices.
