Chocolate and cocoa manufacturer Barry Callebaut has signed a strategic partnership with Amsterdam-based Tony’s Chocolonely to produce chocolate from fully traceable sustainable cocoa.

The agreement will see Barry Callebaut install a dedicated cocoa butter tank in its factory in Wieze, Belgium to produce cocoa butter from sustainable beans sourced from Tony Chocolonely’s partner cooperatives in the Cote d’Ivoire.

Using an industry scalable process, Tony’s Chocolonely will work with Barry Callebaut to create traceable bean-to-bar offerings.

The two firms have already been working together since 2005, when Barry Callebaut started to produce its Fairtrade cocoa liquor. Under the new agreement both the cocoa liquor and cocoa butter in recipes will become fully traceable.

Antoine de Saint-Affrique, CEO of Barry Callebaut, said: “Having made sustainable cocoa one of the four pillars of our strategy, we champion the development of a fully sustainable chocolate value chain. This partnership with Tony’s Chocolonely is a milestone in our efforts to provide fully sustainable products to our customers.”

Barry Callebaut grew revenue and volumes in the nine months to 31 May.
