DUNDEE, UNITED KINGDOM — Tesco supermarket in-store bakeries are turning surplus baguettes and batons into bread pudding and olive oil crostini lines. The move could lead to a 40% reduction in the baguette and baton waste in the bakeries in the United Kingdom.

Bakeries will take the surplus white batons, slice them and top them with extra virgin olive oil. The items then will be baked to a crisp and crunchy texture to create the olive oil crostini. To create bread pudding, the bakeries will break white baguettes into crumbs and then add spices, sultanas and water. Currently, the olive oil crostini and bread pudding are being sold at 24 stores in the United Kingdom. Tesco P.L.C. operates more than 3,400 stores in the country.

“These new fresh bread pudding and crostini lines are made to classic recipes and using bread that’s been deemed surplus at the end of the day,” said Gordon Gafa, bakery category director for Tesco P.L.C. “We’re very proud of our record on tackling bread waste, and this latest move follows other recent measures such as advising customers that they can freeze bread and also reducing the amount of bread we bake in our stores.”

Surplus bakery products have accounted for nearly a third (67,5000 tonnes in 2015) of the United Kingdom’s total retail food waste, according to the charity group Wrap.
