Sanitary landfilling can effectively reduce pollution to groundwater, surface water, soil and air. In fact, large stick bones are classified as "other garbage" because they are difficult to corrode. Corn kernels, nut shells, fruit cores, chicken bones, etc. are food waste. Toilet paper is not recyclable. Toilet paper dissolves when exposed to water and is not considered recyclable paper. Similar items include pottery, cigarette boxes, etc. Even though the plastic bags commonly used for bagging food waste are degradable, they are far more difficult to corrode than food waste. In addition, plastic bags themselves are recyclable waste. The correct approach should be to put the food waste into the trash can and throw the plastic bag into a separate "recyclable garbage" trash can.

Waste cooking oil left at home is also classified as "kitchen waste". Dust is counted as other garbage in the garbage classification. Dust belongs to "other garbage", but fallen branches and leaves belong to "kitchen garbage", including flowers that have bloomed at home.
