In my project, I'm working on a system which can motivate people dump their wastages on garbage bin instead of throwing it everywhere. people will get points on using it in their RFID card or tag which will be given by the shopkeeper. shopkeeper owns the smart bin. points will be depend on the type ( WET / DRY ) and Amount of the garbage. Those pints can be use for getting discount in respective shop.
Smart bin system can also be used in marketing purpose as it contains speaker in controller which address people towards respective shop.

Some Students also tried same concept about this situation.The key idea is to Reward people for making people use Dust-bin
