1. Secondary pollution: A large number of harmful substances, such as carbon dioxide, nitrogen oxides, dioxins, etc., will be generated in the process of garbage incineration. If it is not handled properly, it may cause secondary pollution to the environment.
2. Energy consumption: Waste incinerators need high energy input, including fuel and electricity, which has a certain impact on resource consumption and energy waste.
3. Social impact: The construction and operation of the garbage incinerator may have an impact on the surrounding environment and residents' lives, such as waste gas emission, noise and adjacent pollution. , may cause dissatisfaction among residents and social opposition.
4. Financial cost: Because the waste incinerator needs huge investment cost and operation and maintenance cost, it may be difficult to bear these costs in some areas with weak economic development.
5. Some special wastes are difficult to deal with: such as medical wastes, chemical wastes and other wastes that need special treatment. The garbage incinerator can't completely treat it, and special treatment methods may be needed.
To sum up, although the garbage incinerator can completely treat garbage, there are many problems such as secondary pollution, energy consumption, social impact, financial cost and so on. Scientific management, operation and improvement measures are needed to reduce its negative impact. In contrast, the method of garbage sorting, recycling and reuse can reduce the negative impact of garbage incinerator to a greater extent.
