There is a vending machine in Istanbul that takes bottles for payment and gives food to stray animals in return. Stray animals are generally cared for by the community in Istanbul but now this invention also ensures for a clean environment.
Although this is not a new idea, more and more inventions like this are popping up around the world. Australia recently installed machines that offer bus tickets in exchange for recycling plastic bottles and a ticket machine in Moscow that accepts squats as payment.
This bin was designed by Pugedon and is certainly much needed across the world.
