How to deal with the garbage siege in the development of urbanization

The way to reduce waste is to incinerate. Foreign countries have been adopting it all the time, and the technology is also mature. The reason why China has not implemented it is that the garbage is not classified, and the moisture content of the garbage is too high, which is not conducive to incineration and may cause pollution.

Before incineration, garbage should be classified and used. Incinerate those that cannot be used.

To solve the problem of garbage siege, we can work from the following aspects:

First, improve the awareness of garbage classification among the whole people and advocate the implementation of national garbage classification. The premise of harmless treatment of garbage is to effectively sort the organic, inorganic, toxic and harmful substances in it, and then classify it for treatment and utilization. This requires the whole people to realize the importance of garbage classification and actively join in the garbage classification.

It is also required that the relevant departments have strengthened the publicity of garbage classification and delivery, and increased garbage classification points in appropriate locations.

Second, we need to change the way we dispose of waste, from landfill waste to incineration. Waste-to-energy incineration has become a common waste resource treatment method in developed countries. In this way, a series of hazards caused by landfills can be avoided.

However, this method requires a relatively large one-time investment, and the local government needs to be able to increase financial investment.

Third, we need to establish a uniformly planned urban and rural sanitation system. The environment of China's cities has, to some extent, come at the expense of the rural environment. This is also an important reason for the transfer of urban garbage to the countryside and the formation of a garbage siege.

Fourth, start from the source and promote the reduction of urban waste. This is a goal that requires the concerted efforts of the whole society. It is necessary to increase publicity throughout the society to raise the awareness of environmental protection among the whole people.

In short, it is:

1. Classification, reuse, and adhere to the road of sustainable development.

2. Research and development of clean, non-polluting or low-polluting materials (including pollution generated in the manufacturing process).

3. Improve the quality of the population, strengthen environmental protection publicity, and improve people's awareness of environmental protection.

According to the "Urban Appearance and Environmental Sanitation in Various Regions", the harmless disposal rate of domestic waste in the country that year was only. According to a 2006 survey conducted by the Ministry of Construction, more than 1 3 of the country's more than 600 cities are surrounded by garbage. The national urban garbage dump has occupied a total of 500 million square meters of land, equivalent to 750,000 mu.

In March, Chen Yong, director of Beijing's municipal management committee, said that a garbage crisis was about to emerge in Beijing, "which would be a very terrible thing." "In Beijing, this is not the first time that there has been a "garbage siege". As early as 1983, Beijing spent 2.3 billion yuan to gradually conquer this amazing besieged city.

3. The garbage classification work in Guangzhou, which has been carried out in Guangzhou for 10 years, is facing many serious practical problems. In April 2009, whether to cancel garbage sorting became a hot topic in Guangzhou. Behind this heated discussion is Guangzhou, which produces 9,776 tons of garbage per day, will face the danger of garbage siege in 2010.

4. On the one hand, there is the growing urban garbage, and on the other hand, there is the unbearable stench of garbage, which has become a thorny problem in urban garbage disposal. At Gaoantun, Beijing's largest garbage disposal site, the stench from landfills and dioxins from incineration threaten the lives of nearby residents. Some people don't want to wear gas masks, some people have no choice but to leave, some people actively stand up for environmental protection, take a walk on the street, make posters, and their lives are changed by garbage.

5. As early as 2000, Beijing, Shanghai, Guangzhou, Shenzhen, Hangzhou, etc. were listed as the first batch of pilot cities for domestic waste classification, however, in the past 12 years, the garbage classification work in many cities has been struggling and falling into a situation of survival in name only.

6. Zhao Penggao, deputy director of the National Department of Environmental Resources, said at the ASEAN Expo that the current pressure on China's domestic waste disposal is not small, but the first-class policy and financial support are also very large. Zhao Penggao said that during the "Twelfth Five-Year Plan" period, the focus will be on the harmless treatment of domestic waste, and the state will invest 6 billion yuan to support it, and will introduce relevant favorable policies to encourage enterprise investment. There is also an investment of 45 billion yuan in various localities to encourage clean waste treatment, and private capital will enter the field of waste incineration investment.

In March 1983, the simple landfill of garbage led to piles of garbage in the ring area of Beijing's Third Ring Road and Fourth Ring Road, and there were more than 4,700 garbage heaps of more than 50 square meters! In order to break through the siege, Beijing spent 2.3 billion yuan to gradually capture this amazing besieged city.

More than 20 years later, the garbage monster has made a comeback, with a daily output of 18,400 tons of garbage and a garbage disposal gap of 8,000 tons, with a high gap rate of 47%, like a giant "bomb", hidden under the city.

In Guangzhou, Guangzhou's garbage classification work, which has been carried out for 10 years, faces many serious practical problems.

According to a survey by the Ministry of Housing and Urban-Rural Development, more than one-third of the country's cities are surrounded by garbage, and the country's urban garbage dumps have encroached on 750,000 mu of land.

A few days ago, Zhou Shengxian, minister of environmental protection, pointed out in a report on environmental protection issues that most of the country's 40,000 towns and nearly 600,000 administrative villages have no environmental protection infrastructure, and 100 million tons of domestic waste are generated every year.

Statistics show that among the more than 600 large and medium-sized cities in the country, 2 3 are surrounded by garbage, and 1 4 cities have no suitable place to pile up garbage. Statistics show that the total amount of urban garbage piled up in the country over the years is as high as 7 billion tons, and the amount of garbage produced is increasing at an annual rate, and Beijing produces 10,000 tons of garbage every day, an annual increase of 8%. Beijing's garbage disposal capacity is only 10,000 tons per day, with a shortfall of 8,000 tons.

According to a survey conducted by the Shanghai Academy of Social Sciences in 2010, by the end of 2010, the daily production of domestic waste in Shanghai reached 20,000 tons. Similarly, Guangzhou, as a megacity with a population of more than 10 million in South China, produces as much as 10,000 tons of domestic waste every day.
