Do you know what garbage sorting is? How to classify? What are the benefits of garbage sorting?

Garbage classification is to sort out the renewable resources in garbage and recycle them.

So, how should garbage be classified? Let's talk about the recycling of cool shellfish waste:

Garbage can be divided into the following categories.

1, recyclable garbage

It mainly includes waste paper, plastic, glass, metal, cloth and so on.

2, kitchen waste

Including food waste, such as leftovers, bones, vegetable roots, leaves, peels, etc. Using biotechnology in-situ composting, 0.3 tons of organic fertilizer can be produced per ton.

3. Hazardous waste

Including waste batteries, waste fluorescent lamps, waste water silver thermometers, expired drugs, etc. These wastes need special safety treatment.

4. Other garbage

Including bricks and tiles, waste residue, toilet waste paper, paper towels and other wastes that are difficult to recycle, sanitary landfill can effectively reduce the pollution of groundwater, surface water, soil and air.

So what are the benefits of garbage sorting?

1, reducing land occupation

Some substances in domestic garbage are not easy to degrade, which makes the land seriously eroded. Garbage sorting, removing recyclable and non-degradable substances, reducing the amount of garbage by more than 60%.

2. Waste utilization

China uses 4 billion plastic fast food boxes, 500-700 million instant noodle bowls and billions of disposable chopsticks every year, accounting for 8- 15% of domestic garbage. 30-40% of domestic garbage can be recycled, and all kinds of solid wastes are garbage when mixed together, and resources when separated.

Step 3 reduce pollution

At present, landfill or even simple landfill is mostly used in garbage disposal in China, covering tens of thousands of mu, with insects and flies flying around, sewage overflowing and stinking, which seriously pollutes the environment. Abandoned old batteries contain toxic substances such as mercury and cadmium, which will cause serious harm to human beings, and waste plastics in soil will lead to crop yield reduction.

4, reduce the harm

Waste plastics are eaten by animals by mistake, causing animal deaths. After all, life is precious, so recycling can also reduce harm.

5. Make cities more beautiful.

Garbage is a common thing in our life, and even we have a little resentment in it. After all, garbage is relatively dirty. Garbage classification can be regarded as comprehensive utilization of resources, and there are still many points in refined classification and recycling.
