The garbage has 2 ways to process, one burn it off, pollutant in the air, or you bury them. Taipei Taiwan very small, so your garbage bags required to purchase.

The way how they all eating it luxury outside, and 3 meals a day....

America because the land big, you practically just drag the trash bin outside. You dump everything in it. 

If you eat home, your mother purchase veggie, or you going out purchase veggie, everything home its spoon, fork, bowl, plate....You use detergent or water only. Well, in America, I don't really know they divide their garbage or not, to say standard.
