Save water - eat biscuits!

The three were all working as engineers for big companies in the food industry. They saw how much food gets wasted - about a third of everything that's produced - and wanted to make a difference, to help people, and the planet.

In France, one kind of food that get's thrown away a lot is bread - about 10% of all the bread baked every day ends up in the trash. French-style bread, baked in sticks called "baguettes", goes stale within a few hours.

Alix, Louise and Katia collect yesterday's unsold bread from local bakeries and turn it into something new - biscuits.

Doubly tasty

In fact, the word "biscuit" comes from the Romans and means literally "baked twice". The three biscuiteers grind up dry old bread (which has already been baked once) to make a kind of crispy flour that they mix with butter and water to bake (a second time) into new cookies - in a whole range of flavours.

Not only does it make use of bread that would otherwise go into dumps but it saves massive amounts of water. If you take into account all the water needed to grow the wheat, it takes about 150 litres - a big bathtub - to make just one loaf.

Katia told WoW! News that by using up old bread their Kignon bakery saves enough water to fill 10 Olympic-sized swimming pools every year!
