From a global perspective, what are the main ways of urban garbage disposal?

From a global perspective, landfill and incineration are the main ways of urban garbage disposal.

With the increase of population and the acceleration of urbanization, urban garbage disposal has become a global environmental problem. In different countries and regions, the treatment methods of urban garbage are different. Developed countries usually adopt advanced technology and equipment, such as garbage incineration, landfill, recovery and reuse.

In Europe, garbage incineration and landfill are the most common garbage disposal methods. In Japan, garbage sorting and recycling is an important environmental protection policy. They deal with recyclable garbage and non-recyclable garbage respectively. The garbage disposal methods in these countries are mature in technology and management, which effectively reduces the pollution of garbage to the environment.

However, in some developing countries, there are still problems in garbage disposal methods. These countries usually adopt traditional landfill and incineration methods, but lack advanced technology and equipment. In India and some African countries, unscientific and irregular garbage disposal methods have caused serious pollution to the environment and people's health. These countries need more investment and technical support to improve the way of garbage disposal.

Significance of implementing garbage classification

Garbage classification is the foundation of garbage terminal treatment facilities. The implementation of domestic waste classification can effectively improve the urban and rural environment and promote the recycling of resources. On the basis of scientific and reasonable classification of domestic waste, we will build a supporting system for domestic waste classification, establish a collection and transportation system that matches the classification of waste according to the classified varieties, establish a recovery system that is coordinated with the utilization of renewable resources, improve the terminal treatment facilities connected with waste classification, and ensure the interconnection of classified collection, transportation, recovery, utilization and treatment facilities.

Only by doing a good job in supporting systems such as garbage sorting, garbage recycling and disposal can we operate more efficiently. Garbage classification is related to the construction of a resource-saving and environment-friendly society, which is conducive to further improving the quality of new urbanization and the level of ecological civilization construction in China.
