Do you ever find yourself standing in front of rubbish bins, not sure whether the piece of waste in your hand is recyclable or not To solve this problem, four Hong Kong high school students have invented a smart rubbish bin that uses AI to sort the waste. The students named the bin Waste Collection Point.
The bin uses a camera to know the kind of the waste and sorts it into plastic, paper, glass, or other kinds. To make sure the bin can sort waste correctly, the team tested every product in the school shop and took at least 500 pictures of each one. “To train the AI, we had to take many photos from different angles (角度), so it has a better rate of accuracy,” said one of the designers.
The idea of the smart bin was born two years ago when the students were in Grade Ten. A lot of rubbish was here and there in their village and caused much pollution. Every weekend, they had to join the villagers in picking up the waste.
The students decided to invent a special recycling bin that would encourage people to protect the environment. Although the school ended at 2 p. m., the team members would continue to work on their invention until 6 or 7 p. m. at school.
“Our bin is now in its third generation (代). Before graduation, we hope it can be widely used in the city.” The students said, “Then it will be easier than ever for people to recycle waste and protect our environment.”
