Other (dry garbage)

Other garbage (called dry garbage in Shanghai) includes bricks and ceramics, muck, waste paper from toilets, paper towels and other difficult-to-recycle wastes, fruit shells, dust, and food bags (boxes) in addition to the above types of garbage. Taking sanitary landfill can effectively reduce the pollution to groundwater, surface water, soil and air.
The big stick bone is included in "other garbage" because it is "difficult to corrode". Corn kernels, nut shells, fruit cores, chicken bones, etc. are kitchen waste. [5]
Toilet paper: Toilet paper and toilet paper dissolve in water and are not considered "recyclable" "paper". Similar ones include cigarette cases.
Kitchen garbage bags: The commonly used plastic bags, even if they are degradable, are far more difficult to corrode than kitchen garbage. In addition, the plastic bag itself is recyclable garbage. The correct approach should be to pour the kitchen waste into the trash can, and throw the plastic bags into the "recyclable trash" bin.
Fruit shells: In the garbage classification, the "fruit shell melon skin" logo is peanut shells, which really belong to kitchen waste. The waste cooking oil used at home is also classified as "kitchen waste".
Dust: In the classification of garbage, dust belongs to "other garbage", but the fallen branches and leaves belong to "kitchen garbage", including flowers that bloom at home.

Food waste (wet garbage)
Kitchen waste (wet waste in Shanghai) includes food waste such as leftovers, bones, root vegetables, peels and peels. Through bio-technology on-site composting, it can produce 0.6-0.7 tons of organic fertilizer per ton.
