Tsai Cheng-Yu’s Trash Know has nothing to do with your littering habits. What it intends to bring about is the speedy clean-out of trash in a clean way. Having a roll dispenser at the bottom that holds disposable liners, you need to pull it out and line the bin with it. When the trash bin cannot hold any more garbage, tie a knot on the top and rip the line off.

What next? Just as you do with a toilet roll, pull up the next one and the trash bin is ready to refill once more.
