Urgent! Advantages and disadvantages of garbage sorting

Why do we need to separate garbage?

Each of us throws out a lot of garbage every day, do you know where they go? They are usually sent to landfills and then to landfill.

Landfills are expensive, costing around 200 to 300 RMB to dispose of a ton of garbage. In Beijing alone, there are 12,000 tons of garbage per day, and currently there are more than 700 garbage piles with an area of 36 square meters or more within Beijing's fifth ring road, covering an area of more than 5 million square meters, and increasing at a rate of 3-5% per year. People consume a lot of resources, mass production, mass consumption, and a lot of waste.

The reason for the increase in garbage is the improvement of people's living standards, all consumption has increased. According to statistics, in 1979, the national urban garbage removal is more than 25 million tons, in 1996, the urban garbage removal is 1.16 tons, four times as much as in 1979.

How much land does such a large amount of garbage need to be turned into a landfill? The 60-hectare, 2,000-tonne-per-day Asuwei landfill can handle only one-sixth of Beijing's garbage, and it will be filled up in its 11th year. The abandoned landfill is no longer arable land and cannot be built into a living community.

Another method of waste disposal that is widely used in Western countries is incineration. After high-temperature incineration after the garbage will not take up a lot of land, but it is not only a staggering investment, and will increase the risk of secondary pollution. Dioxin, which is a highly toxic carcinogen, is one of the main gas components produced after waste incineration.

In addition, whether it is landfilled or incinerated, it is a needless waste of resources. We are constantly turning the limited resources of the Earth into garbage, and burying or burning them, so where will our future generations live?

Is there nothing we can do about the garbage? In fact, there is a way, this is the classification of garbage. The first thing you need to do is to separate your garbage at the source, and then turn it back into a resource by sorting it out and recycling it.

The benefits of waste separation are obvious. By sorting garbage and sending it to factories instead of landfills, it saves land, avoids pollution from landfills or incineration, and turns waste into treasure.

Sorting garbage is not new to the frugal Chinese. Maybe you still remember the scene of recycling waste in the 50s and 60s: toothpaste skins were saved for recycling, orange peels were used to make medicine, biological waste was used for composting, waste cloth, ink bottles and so on can be reused. After the classification of garbage, not only to avoid the waste of public health, but also to provide raw materials for industry and agriculture.

The United States is known as a major producer of garbage, garbage classification has gradually penetrated into the lives of citizens, walking on the street, a variety of colorful classification of garbage cans can be seen everywhere.

The government provides a variety of convenient conditions for waste classification. In addition to setting up waste separation bins on both sides of the street, each community regularly assigns a person responsible for removing the waste separated from each household.

Residents have also expressed great support for the government's work on garbage classification. Not only is everyone familiar with the concept of waste separation, but paying for waste separation is as natural as paying for clean tap water.

Garbage recycling as an industry has developed rapidly, and in many developed countries, the recycling industry is occupying an increasingly important position in the national industrial structure. In the United States, three cities Baltimore, Washington and Richmond, for example, the past recycling of waste per ton of treatment needs to spend 40 U.S. dollars, after the classification process, these recycling of garbage in 1995 to create 5100 jobs. In the United States, these three cities are only a very small area, its garbage recycling not only saves the cost of garbage disposal, but also create a wealth of 500 million U.S. dollars.

Garbage sorting is not only a fashion in developed countries like the United States, but also a trend in many developing countries. In Brazil, where garbage sorting is practiced in many communities, the mayor has made the sorting bin at the front entrance of the city hall the glory of the city. And at more than two dozen nearby beaches, the bins are a beautiful sight.

In some parts of the Philippines, villagers have organized themselves to clean up their living environment, and sorting garbage is a major part of this movement.

While waste separation is becoming a global trend in both poor and rich countries, it is a good tradition that has been lost in China, once a world leader in this field.

While others have learned to pick up from us, we have learned to throw away from others. As our lives get better, we no longer skimp on the few cents we get for selling our rags, and would rather throw them away as garbage. Thrift and frugality, the utilization of waste, the traditional virtues of the Chinese people, seems to have been yi moi? Ode? The traditional Chinese virtue of saving and recycling seems to have been lost in the past. The kind of equipment Nao test block Blossom flash ship round Jian?

Each of us is a garbage maker, and isn't this mountain of garbage piled up by our own hands, family by family?

We are also the victims of garbage, these mountains of garbage devouring resources and polluting the environment is to be ourselves and our children and grandchildren to bear the consequences?

We should be more the rulers of garbage nuisance, and each of us can overcome the garbage nuisance by separating garbage.

On December 15, 1996, residents of Dashang Lane in Beijing's Xicheng District, with the help of the civic organization Global Village, began sorting garbage from that day forward. The initial sorting bins were purchased by members of the family committee with their saved year-end bonuses. The sorted garbage is removed by vendors and businesses contacted by the family committee. Day after day, year after year, the residents never interrupted.

As a small spark of civil garbage classification, the action of the residents of Dashang Lane ignited the enthusiasm of many citizens, and since '97, a number of universities, primary and secondary schools in Beijing, as well as a number of retired elderly people have made attempts to categorize garbage. With the help of China Youth Newspaper's Sister of Knowledge and a female doctor who returned from studying in Germany, these "Hand in Hand Global Village" children also used the money exchanged for recycling to build a school.

The behavior of the public and the children attracted the attention of the relevant government departments. The Xuanwu District Sanitation Bureau took the lead and started a pilot project in the fall of 1997 to separate garbage and recycle in Xuanwu District. The Civilization Office of Xuanwu District and the streets, as well as the civil society organization Global Village, gave active cooperation.

On April 23rd, 1999, the Jiangong Nanli neighborhood community in Baijifang, Xuanwu District, was buzzing like a festival as China's first garbage sorting and recycling system was officially launched. From this day on, residents will change the way of garbage mixing and put it according to the classification of organic, inorganic and discarded soil, and the government sanitation department will change the way of mixing and transporting it to sorting, picking and recycling. It means that old traditions that have been lost here for years are finally being picked up.

In this battle between people and garbage, people have turned garbage from an enemy to a friend. Someone once compared garbage to a misplaced resource. Let's go to Xuanwu District Recycling Sorting Station to see what kind of use garbage will have once it returns to its rightful place.

Every day we discarded the Coke bottles and known as white trash plastic bags, disposable plastic lunch boxes, belonging to the polymer polymerization of organic matter, if buried in the ground, it is 100 years 200 years can not be rotten, it will also make the soil agglomeration, reduce the fertility of the soil, and even make the soil lose the ability to cultivate. In our lives, we often throw away all kinds of waste plastic. Waste plastic can also be made into buttons, pen holders and other supplies after treatment. Waste plastic is also a good raw material for oil refining. Some people once compared them to the image of "secondary oil field". 1 ton of waste plastic at least 600 kilograms of gasoline and diesel back to the refinery.

In the recycling station, we see a variety of waste paper was sent here, including these inconspicuous little pieces of paper ...... We know that good paper is caused by wood, a ton of waste paper can be recycled 700 kilograms of good paper, can be less than 17 trees, but also reduce the production of pulp in the process of water pollution.

But because of China's waste paper recovery rate is still very low, only 20% or so, every year, we have to import a large number of waste paper only 96 years on the import of 1.37 million tons of waste paper. You may remember the 1980s, the sensational "foreign garbage" incident, that a boatload of foreign garbage is under the banner of imported waste paper mixed in.

The foreign garbage was driven away, but left behind reflections, why do we have to import waste paper from other countries to do the raw material for paper making? Why we can not maximize the recovery of waste paper, but let them mixed in the garbage buried or burned? China's forest resources are only 1/4 of the world's average, and China's rivers and lakes have been seriously polluted by early sewage discharge. If each person throws away an average of half a kilogram of all kinds of waste paper every week, then only one city, Beijing, will throw away more than 6,000 tons of waste paper a week.

China has a historical tradition of recycling waste products, we used to recycle waste, perhaps only by the economic constraints of poverty as a last resort; in the gradual affluence of today, we recycle waste paper, is to protect the environment consciously aware of and take action. Because we clearly know that what we picked up is not only a piece of waste paper, that is our children and grandchildren to live in the forest and the river.

Garbage, only when mixed together is garbage, once sorted and recycled are precious, even the kind of waste batteries that have become miniature killers can be turned into profit. In this inconspicuous photo studio, we see such waste battery recycling box. The batteries we use in our lives generally contain mercury or cadmium and other toxic heavy metals, these heavy metals if left in the ground it is easy to rain through the leaching, into the groundwater.

This kind of pollution is very difficult to exclude, biological half-life is about 30 years, that is, you 30 years to discharge half. So this is particularly harmful to people. Waste batteries contain a variety of useful metal minerals, the value of recycling is very high.

Because of the serious harm and special recycling value of waste batteries, many countries strictly prohibit them from being mixed with garbage, and Japanese communities have this yellow bucket, which will be placed separately for button batteries and so on.

Since '97, some citizens and students in Beijing also acted on their own initiative and consciously categorized and collected waste batteries, and young volunteers from Renmin University helped set up a waste battery recycling box for a chain store in the capital.

As a positive response to the citizens' campaign, the Beijing Municipal Bureau of Sanitation set up a special waste battery collection point to collect waste batteries and centralize their harmless treatment.

Do you know what biowaste is? Biological waste is leftover raw food, eggshells, fruit leather, picking gangs of vegetables and leaves of a kind of kitchen garbage. These seemingly strange waste can be used for what it turns out they can be used to make a good organic fertilizer. Like the locust cypress tree community in this big Nano dream biological waste treatment machine, can be biological waste drying, crushing, made of efficient organic fertilizer. Residents can use it to plant flowers and grass.

The vegetables planted with them are safer and healthier than fertilized food, and are quite popular in supermarkets. Biological waste usually accounts for 40% of the total waste, if they can be turned into organic fertilizer, not only to save land for landfills, but also to save vehicles and energy to transport them, but also to prevent them from breeding mosquitoes, flies and bacteria. Experts have suggested that the government should install bio-waste treatment machines in all neighborhoods and set up bio-waste treatment rooms in new neighborhoods.

At that time, we will be able to see that the classification of garbage to create a garbage-free society, a recycling society, and all this requires only our hands.
