Failure to separate wet from dry will make the garbage incineration process more difficult and waste more energy.

Dry garbage refers to garbage that does not rot. Dry garbage is less harmful, but has no recycling value. It can be treated by incineration and landfill. Wet garbage is rotten garbage, that is, organic garbage can be made into fertilizer through biological treatment. Because dry and wet garbage are recycled in different ways, they should be separated.
