Hu Xinyuan has designed a micro-level system to deal with trash called the Trash Classification Bin. Nobody I know likes to sort through garbage, but this will make the job a little more enjoyable. The smaller "bin-in-bin" is used to hold organic waste, while the big bin holds everything else.

The pictures show some diagrams about how the Trash Classification Bin works. The second picture is actually quite hilarious to read, so if you're up for a laugh, I would really recommend taking a look!
