Martin Herbelin stands in front of a glass case brimming with golden, buttery croissants and flaky pain au chocolat — all of which were destined for the trash just 12 hours earlier. At Demain, his Paris bakery with a conscience, yesterday’s pastries are today’s triumph. The bright blue storefronts of Demain’s three locations hum with customers snatching up sourdough loaves for €4 — half price — and almond croissants for just €0.50, all rescued from over 20 of the city’s beloved artisan bakeries.
In a country where the baguette is practically sacred, it’s striking that 10% of daily bakery output goes unsold — amounting to 345,000 metric tons of waste each year in France alone. Demain is rewriting that story, one day-old pastry at a time. Since launching in 2023, the company has built a nightly rescue operation, collecting unsold bread and pastries after closing time and reselling them the next morning. The impact is tangible: 50,000 edible items saved every month from landfill, with 95% of collected goods successfully sold.
But Demain doesn’t just sell leftovers — it reinvents them. Croissants that might lose their crispness by day two are flattened, caramelized, and reborn as “smash croissants,” a crunchy, indulgent treat. Stale pains au chocolat are fused into a decadent rebaked “Chocobread,” while old baguettes become the base for warm, gooey “toastie” sandwiches filled with fresh cheese and vegetables. Even the crumbs find purpose, mixed into new doughs or toppings. Nothing is wasted, because, as Herbelin insists, “There’s so much value in what we are throwing away.”
The model is catching on fast. From its first store in 2023 to a third opening in June 2026, Demain now employs over two dozen people and works with renowned bakeries like Land&Monkeys, Terroirs d’Avenir, and BO&MIE. The initiative taps into a growing cultural shift — one that challenges the notion that food must be perfectly fresh to be valuable. In a world where a third of all food produced is wasted, and Europe alone discards 58 million metric tons annually, Demain offers a delicious, practical solution.
This isn’t just about saving croissants. It’s about changing mindsets — proving that sustainability can be affordable, accessible, and deeply satisfying. As Herbelin puts it, “Once you do, it could have a huge impact.” With every bite of a rebaked pastry, Parisians aren’t just feeding themselves. They’re helping bake a better tomorrow.
