Trashfeed - The Smart Trash Can

According to a survey we put out, quite a few people have trouble finding trash bins in public places when they need them. But if we actually look around, they're literally everywhere. The problem is they can be hard to spot. 

The survey also seems to say that a good amount of people will litter if they can't find the trash can fast, so they need it to be convenient for them. Another group of people just aren't motivated to go look for them.

That is why we've come up with this product.


  • Comes in different bright colors that make it easy to spot in public
  • The trash bin also comes in a 3-in-1 layout, that allows for throwing out things like regular trash, paper and plastic. This helps with the recycling.
  • The bin has a speaker and LEDs around the top that plays a fun, motivating victory sound and blinking lights when you throw trash in
  • There is a sensor inside that detects when the bin is almost full, and the LEDs will switch to red
  • The sensor also sends a signal to a trash collection company that says it is ready to be emptied. They can use this information to plan their routes to only pickup the full trash cans. This can help reduce fuel usage which is always good for the environment.
  • Powered by an easily-swappable, rechargeable battery

In the provided photos, the point is not to focus on the look of the trash can, but the features listed above. These features can be implemented to pretty much any type of trash can for whatever situation or location it is in.



Sensor details:

There are two options you could choose from, depending on the specific needs and situation. An ultrasonic sound wave sensor & an infrared (IR) sensor, or just an IR sensor. 

  1. One infrared (IR) sensor only
  • In this case, the trash bin would be equipped with only one infrared (IR) sensor that would both detect the trash thrown in, and also if the trash inside the can has gotten to the sensor’s height, and therefore be almost full. This sensor would be placed close to the top inside the bin, and connected to the replaceable battery on top. Whenever trash is thrown inside, the IR light beam would be obstructed and it would mean that trash has been thrown. If the beam is obstructed for a longer set period of time, say 5 seconds, that would mean that trash has risen to that level and therefore the bin is practically full.
  1. Ultrasonic & IR sensor
  • This solution would use ultrasonic sound waves to detect the exact fullness level of the trash can, while also being able to quickly detect obstructions with the IR sensor, like when people throw garbage in, and the speaker needs to play the sound.
  • The ultrasonic sensor has a Wi-Fi module which will send the data to a remote web server and display the trash bin details in real-time. The sensors can be easily mounted and attached to bins made of different materials.

The ultrasonic & IR sensor combo has the advantage of being able to provide much more detail about the fullness of the trash bin, but also being more expensive and power hungry than only the IR sensor counterpart. 

When should this trash bin be used?

This bin is not meant to replace every trash can in the country, but to place in special hotspots, for example in a city in an area that is known to have issues with littering and being full often. 

Could also be used during events like festivals to make it more fun for people to throw out trash and to make it easily seen. These events, it is crucial to have good trash management, so the 3-in-1 layout is great here as well, and it also helps a lot with the general enjoyment of the festival if there is not trash on the ground everywhere.
