Since July this year 1, Shanghai has entered the era of garbage sorting, and residents will be punished for taking out garbage at will, the highest in 200 yuan. Domestic garbage can be divided into harmful waste, recyclable garbage, wet garbage and dry garbage.

Harmful waste refers to: waste batteries, plastic bags (white pollution), expired food (and leftovers, etc. ), expired drugs, discarded medical devices (syringes, needles, infusion sets, disposable gloves, etc. ), discarded waste paint, lamps, etc. If these rubbish are discarded at will, it will not only pollute the environment, but also produce non-degradable toxic substances.

Recyclable things refer to: books and newspapers, waste paper, beverage bottles, broken carpets in our home, and now overwhelming express cartons. These are all recyclable items. Don't underestimate the rubbish. Some people make a fortune through it, others throw it away at will, polluting the environment.

Wet garbage refers to garbage containing water or oily lipids. Wet garbage mainly comes from the kitchen, and the peel with water and the food garbage in the kitchen are all wet garbage. Wet garbage can be turned into fertilizer after processing.

Dry garbage refers to the garbage generated in daily life. Except for wet garbage and recyclables, the rest is basically dry garbage. At present, these wastes will be sent to incineration or landfill.
