Keeping the Swachh Bharat (Clean India) Mission in mind, four students from Sandip Polytechnic came up with a way to incentivise waste disposal and make India’s streets litter-free.

Their premise is simple yet effective — throw your garbage into their smart dustbins, instead of just around it, and get rewarded with coupons and/or cash. They named their product KRRYP GarbageATM. “KRRYP expands to our initials, since we are the students who developed the project,” says Yash Gupta, one of the team members. The students devised and worked on the project while doing their diplomas in electrical engineering, which they recently completed.

It took the team about seven months to implement the prototype, while balancing their studies. Their time spent on the project was not without struggle. “We had to do a lot of complex coding for this project. Also, equipment with good accuracy wasn’t easily available in Maharashtra,” says Prakash Sonawane, another team member.

Rushikesh Kasar explains the working of the smart dustbin. You get rewarded not only for trash disposed, but also based on your general knowledge (GK). “Our system consists of two bins — A and B, an LCD display screen and an RFID (Radio Frequency Identification) reader. Users will be given a card, which must be swiped first. They are then shown their details as read by the RFID reader. The screen displays a GK question, with two possible answers, A and B. The individual then chooses which bin to dump the garbage, based on what they think is the correct answer.”

Get rewarded

Yash continues, “Then, they will get points added to their card, based on amount of garbage disposed, and whether they answered correctly. They can use the points on their cards to recharge their phones or for shopping.”

So far, the students have presented their GarbageATM prototype at various competitions in Maharashtra and Delhi, and have received a positive response. Says Rahul Patil, team member, “People are eagerly waiting for this project to be fully implemented so that they can earn something while disposing of their garbage properly. We are searching for sponsors to help us implement our project in major Indian cities as early as possible.”

Rahul signs off, “We are planning for an improvement where the bins will separate different kinds of waste also. Soon you all will see our KRRYP GarbageATM at public places like railway station, bus stands, airport, and so on.”
