Leftovers
Invent a machine that recycles your leftover dinner
No time to waste
Did you know that 1 third of all food produced globally goes to waste? Will your machine sort through the food and make a new meal ready for tomorrow? Or will your machine show you what food you can use as composte to help your plants to grow? Leftover food actually has a lot of uses and many people make sure they never waste any food - not even the skin of bananas! How will your machine save food waste?
