(TheDrinksBusiness) - Château Smith Haut Lafitte in Bordeaux is to turn its carbon emissions into toothpaste. Speaking to the drinks business at an en primuer tasting of the estate’s wines last week, co-owner Daniel Cathiard revealed details of the unusual plan.

“Our aim is to be as green as possible, so we’re going to capture the carbon emitted during the fermentation process and turn it into bicarbonate of soda to be used in toothpaste,” he said. “We don’t want to waste anything here, so why not make the most of our carbon? We produce a lot of C02 at the winery and we want to be like a forest and capture it,” he added.

Cathiard told db that he would turn the carbon from a gas into sodium bicarbonate and sell it on to pharmaceutical companies for use in toothpaste. He plans to make his first batch of bicarbonate of soda this year.
