After a two-year cycling trip from Paris to Beijing and completing his engineering studies, Franck Wallet decided to dedicate himself to fighting bread waste with his innovation, the Crumbler. Confronted with the massive volumes of unsold bread thrown away each day, he realized that surplus bread could simply be transformed into artisanal breadcrumbs — a high-quality raw material that also helps artisans save money.
These breadcrumbs can be incorporated into pastries, doughs (at varying percentages), or even used as dusting flour. Since the first Crumbler was installed in 2018, more than 650 machines have been deployed across France and internationally, saving the equivalent of over 3 million baguettes every year. The initiative is supported by Meilleurs Ouvriers de France (MOF), who ensure the quality and consistency of the recipes developed.
