With the development of society and the acceleration of the process of urbanization, the urban population is increasing day by day, people’s living standards are constantly improving, and the amount of urban domestic waste is also constantly increasing. The composition of waste is also becoming increasingly complex, which will pollute the environment and people’s health. The hazards are becoming more and more serious, thus restricting the development of the city. 

The hazards of municipal solid waste:

1. Occupy land
During the process of stacking a large amount of domestic garbage and after closing the site, a large amount of vacant land or land for other purposes is occupied. After the domestic garbage dump is used and closed, the nature of land use has also changed, resulting in a serious waste of land resources. The domestic garbage that has not been strictly treated is directly used in farmland, which not only changes the physical and chemical properties of the soil, but also harms crops.

2. Pollution of water bodies
Due to the many sources of municipal solid waste, corruption, decomposition or interaction occurs during the stacking process, producing a large number of pathogenic bacteria, organic matter and inorganic pollutants, which enter the water body with surface water sources such as leachate or rainwater, causing serious pollution of the water body .

3. Pollute the atmosphere
The composition of garbage is complex, and some garbage, such as plastic bags, can float in the wind, causing white pollution. At the same time, domestic garbage can release harmful gases such as methane, hydrogen sulfide, and ammonia during the stacking process, which endanger the surrounding atmosphere.

4. Affect environmental health to spread diseases
At present, with the rapid increase in the urban population, the amount of urban household waste and fecal discharge is also increasing. Garbage and excrement enter the environment without harmless treatment, which not only seriously affects environmental sanitation, but also poses a potential threat to people's health. The garbage dump is a breeding source of a large number of mosquitoes, mice, and pathogens, and there is an unknown danger of an outbreak of plague.
In addition, in many places, the domestic waste is screened and applied directly to the farmland. As the parasite eggs are not killed, they will return to the human body through crops and cause disease transmission.

5. Easy to cause explosion accidents
With the increase of the organic matter content in the municipal solid waste and the change from open-air scattered storage to centralized storage, only simple coverage can easily create an anaerobic environment that produces methane gas and increase the amount of landfill gas produced by the waste. According to research, methane content between 3%-15% will cause explosion.

For municipal solid waste, the principles of reduction, resource utilization and harmlessness should be adhered to to reduce its impact on the environment. The use of incineration to dispose of municipal solid waste has become a necessary means in some countries to dispose of municipal solid waste. It is recommended that you use a professional high-temperature domestic waste incinerator, which can meet the requirements of reduction and harmlessness, and no smoke will be generated after special treatment, which meets the national treatment requirements!
