When it comes to the environment, we all have to pitch in. While it is best to minimize the amount of waste we produce, there is still garbage that we have to take care of.
One of the best ways to dispose garbage is to segregate it. You can always sell recyclable materials such as paper, plastic and glass. For the remaining, you would need to throw it away properly.
Now Hangzhou, a Chinese city, is showing the world just how to do this with QR codes.
Residents in Shiba Street were given two sets of garbage bags that had QR codes on them. One group were for food wastes while the other group were for other types of garbage.
So all you have to do is to put the trash in the right bag. Once the bag is filled, you take them down to the collection point. The trash bins have a scanner built into it. You just let the scanners scan the QR code on the trash bag. The right door will open and you can now throw your garbage into the right bin.
But the system gets better. The bags also have indicators as to where it is from. The idea is to encourage people to put their trash in the right bag. They earn point for doing so and they lose points if they put the wrong things in a bag. They can then use these points to purchase stuff at online supermarkets.
Sound like a great idea right? This is not the first time that QR codes have been used to teach people about the environment. A similar idea was used in New York City where QR codes are to be found at the back of sanitation trucks. When scanned, users are directed to a video that talks about recycling.
