Did you know that cigarettes take twelve years to decompose on average? That’s a big problem, as they are the most littered item on Earth – every year, approximately 4.5 trillion cigarettes are discarded with little regard for the environment. The new startup Crowded Cities has a plan for ridges of this type.

It’s a well-established fact that crows are one of the smartest animals in the world. Not only are they skilled problem solvers, they can create and use tools. Dutch startup Crowded Cities is developing a device that trains crows to collect discarded cigarettes. In exchange, the crows receive peanuts.

The CrowBar is based on a design created by an American inventor. The device has a large funnel where cigarette butts can be deposited, and a dispenser for releasing peanuts. The hope is that crows get busy cleaning up the streets in exchange for some easy food. The task isn’t impossible, considering Crowded Cities has a four-step plan to train the crows.


First, the machine offers a piece of food next to a cigarette butt on a small platform. This trains the bird to expect food from the machine. Second, the machine begins dispensing food only after the crow arrives at the machine. This teaches the crow how to operate the CrowBar. Third, the machine presents only the cigarette butt with no food. Confused, the crow will begin pecking and looking around. When he/she inadvertently drops the butt into the dispenser, food will be released. The fourth step is to remove the cigarette butt entirely, leaving only a couple scattered on the crowd in the nearby area. The crow will begin collecting butts from the surrounding area, bringing them to the CrowBar, then dropping them into the dispenser for food. At this stage, the training is complete.

The startup is in the process of building a prototype to test whether or not the design will work. Because cigarettes are filled with toxic chemicals, Crowded Cities will monitor the crows’ health and behavior. If the method proves successful and the birds aren’t adversely affected by the cigarette butts, you may see a CrowBar in your city in the near future.
