It is harmful waste who will die if the pig eats it.

harmful waste will die if a pig eats it. This is a formula that everyone summed up after the garbage classification in Shanghai. In fact, this formula is not reliable. You can't take these formulas seriously.

The formula for judging the types of garbage circulating on the Internet is as follows: pigs can eat wet garbage, pigs don't eat dry garbage, pigs will die if they eat it, and those who sell them can buy pigs are recyclable garbage.

This formula was spread in the early days of garbage sorting in Shanghai. At that time, the public didn't have a deep understanding of garbage sorting. This formula has some truth, but it is not reliable to take pigs as the judgment yardstick. Later, the official issued a guide to the classification of domestic garbage in Shanghai to guide the public to correctly classify garbage.

In garbage classification, domestic garbage is divided into four categories: harmful waste, recyclable, wet garbage and dry garbage.

harmful waste: refers to the domestic wastes such as waste batteries, waste lamps, waste medicines, waste paints and their containers, which cause direct or potential harm to human health or the natural environment. Common ones include waste batteries, waste fluorescent tubes, waste light bulbs, waste water silver thermometers, waste paint barrels, expired drugs and so on. Hazardous and toxic garbage needs special and correct methods for safe disposal.

recyclables are garbage that can be recycled. Paper, cardboard, glass, plastic, metal and plastic packaging that can be reused by themselves or materials, such as newspapers, magazines, advertising leaflets and other clean papers related to these materials can be recycled.

recyclables mainly include five categories of domestic garbage: waste paper, plastic, glass, metal and textiles.

Waste paper mainly includes: newspapers, magazines, books, all kinds of wrapping paper, office paper, cartons, etc., but paper towels and sanitary paper cannot be recycled because of their strong water solubility.

Plastics mainly include: various plastic bags, plastic packaging materials, disposable plastic lunch boxes and tableware, toothbrushes, cups, mineral water bottles, etc.

Glass mainly includes: various glass containers. According to the recycling process, glass can be divided into colorless glass, green glass and brown glass;

Metals mainly include: cans, metal cans, decorations and aluminum foil, etc. According to the recycled materials, they are classified as iron and non-iron (generally referring to non-ferrous metals).

textiles mainly include: discarded clothes, towels, schoolbags, cloth shoes, etc.

Wet garbage is also called kitchen waste and organic waste, that is, perishable garbage, which refers to perishable biomass domestic waste such as food waste, leftovers, expired food, melon skin and stone, flowers and green plants, and Chinese medicine residue.

Dry garbage refers to other garbage, which refers to other domestic wastes except recyclables, harmful waste and kitchen waste (wet garbage).
