Municipal solid waste, due to its physical and chemical characteristics, can easily pose a threat to human living environment and physical health if not effectively treated and recycled in a timely manner. The reason why municipal solid waste poses a threat to the survival of humans and other organisms is mainly influenced by its characteristics such as concealment, hysteresis, accumulation, association, and synergy. Therefore, the comprehensive disposal of municipal solid waste is very important.
Municipal solid waste is divided into domestic solid waste, industrial solid waste, and hazardous solid waste.
1. Domestic solid waste
Domestic solid waste refers to the solid waste formed in the daily life of citizens, mainly including daily household waste, kitchen waste, commercial waste, medical waste, etc. Due to the wide coverage of domestic solid waste, the daily amount of domestic solid waste generated in cities is very large. This type of waste contains various harmful substances, including polymer plastics that are difficult to naturally degrade and waste products containing heavy metal elements. If not effectively treated, it will cause irreparable damage to the environment.
Domestic solid waste contains a large number of recyclable materials. For example, high calorific value combustibles can be prepared into alternative fuel (RDF, SRF) to reduce the use of coal, organics can be made into compost or used for biogas digester fermentation, and high value recyclables such as plastic, glass, metal, waste paper can be directly renovated or processed as raw materials. The comprehensive disposal process of domestic solid waste designed by GEP Ecotech can be flexibly adjusted and configured according to different types of domestic solid waste to meet the needs of different projects.
2. Industrial solid waste
Industrial solid waste refers to solid waste such as mining waste, smelting waste, and fuel waste formed in industrial and transportation production. It is mainly necessary to classify non-toxic and toxic waste, and whether the classification is correct will have a direct impact on people's life safety. Generally speaking, toxic waste residue, an industrial waste, contains elements such as fluorine, mercury, arsenic, chromium, lead, etc., as well as radioactive element, which need to be properly classified and treated.
3. Hazardous solid waste
Hazardous solid waste is a solid waste with certain toxicity, flammability, and corrosiveness, and its conceptual scope falls between domestic solid waste and industrial solid waste. For example, medical waste from domestic solid waste and toxic waste residue from industrial solid waste are both hazardous solid waste. These hazardous solid waste, if not properly treated in the production, transportation, storage, and treatment processes, will seriously affect the environment. At the same time, hazardous solid waste generally infects internal organs through the human respiratory and skin systems, ultimately leading to organ failure. This has a strong risk, so it needs to be properly handled to prevent harm to the environment and human health.
For these "time bombs", simple shredding treatment cannot be carried out, as they may burn, explode, or cause gas/liquid leakage during the shredding process. Therefore, hazardous solid waste disposal equipment must have very high safety and airtightness. The tower type hazardous waste crushing system developed by GEP Ecotech not only achieves automated treatment of hazardous solid waste, but also strictly controls safety aspects, fully considers safety issues such as material characteristics and hazardous factors in process configuration and structural design, and is equipped with an intelligent detection system, making the comprehensive disposal of hazardous waste more reassuring.
Municipal solid waste has high value in resource utilization. As a manufacturer of comprehensive disposal equipment for municipal solid waste, GEP Ecotech will continue to make precision manufacturing, making contributions to improving the comprehensive utilization capacity of global city municipal solid waste resources.
