After the bottle bank that works like a fruit machine and the litter bins that sound like they are hundreds of feet deep, here's another clever way to make people dispose of their litter correctly - you help feed dogs.

A company in Turkey called Pugedon has created the food dispensing bottle banks to feed the city’s stray dogs. The profit from the recycled bottles covers the cost of the dog food that the machine dispenses.

Istanbul is known for its high number of stray dogs – some estimates say that there are as many as 150,000. Some locals love having the dogs around, who have adjusted so well to city life that they stop at traffic lights and walkways. Others want to get rid of them because of their aggression and their role as disease vectors.

But no one wants them to starve.
