With the development and progress of society, our domestic waste is increasing, which seriously affects the living environment and physical and mental health of human beings. Faced with such a predicament, how does my country deal with urban domestic waste under the concept of sustainable development? What are the methods for treating urban domestic waste?

To achieve sustainable development of urban waste treatment, we must start from its source, that is, to control the generation of unnecessary garbage in life and promote the reduction of garbage. The main measures of domestic waste treatment projects include changing the use structure of urban life fuels, vigorously promoting clean energy, and popularizing the advantages and benefits of clean energy, such as natural gas, so as to reduce the ash produced by coal burning in garbage, thereby achieving the effect of reducing garbage production.

In addition, it is necessary to continuously reduce the use of disposable commodities in daily life, such as disposable lunch boxes, chopsticks, paper cups, etc. The use of such materials will not only increase the output of garbage, but also cause waste of social resources. In view of this, national and local government departments should formulate corresponding legal norms to limit the sale and use of disposable products, and set up resource taxes or garbage taxes to restrict and achieve mandatory recycling. In the production of agricultural products, various vegetables can also be preliminarily processed during sales, which can help reduce kitchen waste.

The changes in the composition of urban domestic waste and the development of social economy have put forward requirements for the recycling of waste. Garbage classification and collection is the basis of garbage recycling. Each city should propose a garbage classification plan based on actual conditions and gradually promote garbage classification and collection. Under the guidance of the concept of sustainable development, garbage disposal methods should also be transformed from the past single-mode treatment to a comprehensive treatment method. The realization of harmlessness is the main goal of comprehensive treatment, which can improve the utilization efficiency of related resources.

And it can unify the methods of garbage disposal, treatment equipment and recycling methods. The treatment method of garbage should be scientific and reasonable and adapted to local conditions. For those economically developed areas, the combustible content in the garbage is relatively high, the calorific value is relatively high, the treatment technology is relatively advanced, and there is sufficient capacity to adopt incineration treatment. For cities with relatively backward economies and sufficient land to build sanitary landfills, it is recommended to use sanitary landfill and composting methods to treat domestic waste.

Since there are many cities in my country, the scale and economic development level of cities vary greatly, the composition of garbage is also different, and residents' environmental awareness and knowledge of garbage classification are limited. The realization of resource utilization of urban domestic waste treatment is a gradual process, which should be implemented in accordance with the step-by-step procedures. For example, it can be implemented first in key cities with developed economy and high management technology level in China.

In the process of implementation, we should actively accumulate experience and summarize lessons, continuously improve the internal procedures of resource system development, and continuously improve the level of existing domestic waste treatment technology and equipment, and move closer to foreign advanced waste treatment technology and management level, so as to gradually realize the classification and resource utilization of urban domestic waste.
