Switzerland does this too, the bags have a little stamp or sticker that costs $5. There are also 10 different bins to presort waste. It works quite well. They put a lot of effort into the design and ease of use at the collection stations (which are free vs the for pay garbage). It's called "polluter pays". They also enforce like Taiwan, $10,000 find for illegal dumping. And they actually look through your trash for bills and letters with your address. The Swiss don't seem to love the system, more like tolerate it.
