The problem Zero Waste solves

Lack of willingness in maintaining a clean society.
Overflowing waste bins are a great concern.
Concern for sanitization and lack of responsible citizens.
The dustbin is there but trash is everywhere.
Establishment of Automated touchless Bins using Ultrasonic Sensor which will detect a person in close proximity and take a response to open the lid of the bin which will promote sanitization in society.
A bin that brings you rewards when you feed it with some trash.

It adds credit coins to your dashboard every time you clean the surrounding which can be redeemed to buy Exclusive Coupons from partner companies or can be converted into real-time cash.
To tackle overflowing bins due to improper management, we asked the bin to send an email to the concerned authority as soon as it is filled. Using IFTTT, IR Sensor, and Node MCU was easy, yet it solved a big problem that will surely bring a change in the environment.
