  • 2.12 billion Tons of waste is dumped into the environment a year

Problems with ordinary waste management systems.

  • Punctuality issues
  • Truck drivers can miss some points
  • No method of collecting data

Solutions for the problem

  • Mobile app that makes hype about waste management among users
  • A trash can that enables users to throw waste while walking
  • Smart trash can

Smart Trash Can solution

Smart Trash Can or else EcoBin is a system created to collect info about waste and manage it easily. This system is specially made for the government. It consists of 3 parts, which are, the transmitter, the receiver, and the application. The transmitter is a mountable component to the existing dustbins and it transmits data about filled and methene amounts using radio waves. The receiver is the part that collects data coming from all the dustbins. Application is used to display all the data. It allows users to interact with this system.
