Pudegon is a company in Turkey that has created an effective way to kill two birds with one stone. The vending machine they created takes bottles deposited for recycling and dispenses food in return for stray dogs. The profit from the recycled food covers the cost of the dog feed. There are a large number of stray dogs in Istanbul. Some estimates put the number at 150,000. There are some locals who love having street dogs who are now used to stopping at traffic lights and walkways. But there are also those who want to get rid of them because they carry diseases and tend to be aggressive.
The machine gives the opportunity to feed the stray dogs and also gives locals the incentive to recycle their bottles. When bottles are recycled food is dispensed to their trays. If you don’t want your water, you can always get rid of it in the water tray which the dogs can drink.
