What are the criteria for garbage sorting What are the criteria for garbage sorting

Food waste is uniformly disposed of according to the solid waste treatment method. The treatment methods mainly include physical method, chemical method, biological method, etc.; The specific treatment technologies include landfill, incineration, composting, fermentation, etc., in short, its resource reuse shows a trend of diversification. According to the different application scopes and actual situations, the following methods are mainly introduced.

1. Physical sorting and processing is mainly to use a series of methods to realize the separation of various components in the garbage, and then unify it. On the one hand, this method achieves a great deal of utilization, and on the other hand, it minimizes the pollution that may be caused by garbage. However, due to its high cost, most countries do not use this method, except for a few developed countries.

2. Crushing the straight row method, the United States has successfully developed the individual family as early as the 40s of the last century....

Garbage classification is to classify garbage in accordance with certain regulations or standards, which is convenient for centralized management.

However, the most important garbage is the useful garbage in the garbage, which includes beverage bottles, cardboard boxes, waste clothes, waste plastics, waste paper, waste glass, waste metal and other wastes suitable for recycling and resource utilization.

Hazardous waste refers to energy-saving lamps, waste batteries, fluorescent lamps, waste drugs and other wastes, which can easily cause direct or potential harm to the environment if not properly placed.

Wet waste refers to food waste. It contains grain, legumes, vegetables and fruits and other garbage, which can generally be decomposed and composted by soil.

Dry garbage refers to napkins, toilet paper, diapers, ceramic tiles, etc., which not only cannot be composted, can not be dissolved, but also occupy a large amount of arable land.

Garbage** can not only reduce the pollution of garbage to the environment, but also turn waste into treasure.
