Underground Waste Collection Storage System is a modern urban sanitation solution that places the main facilities for garbage collection and storage underground. It aims to address the problems of space occupation, odor diffusion, visual pollution and secondary pollution that exist in the traditional surface garbage collection methods.

Product Advantage
Space optimization: Only the discharge outlet is left on the ground, releasing urban public space and avoiding the occupation of roads by traditional trash cans.
Health improvement: The fully enclosed design reduces the spread of odors, mosquito breeding, and garbage exposure, thereby lowering the risk of secondary pollution.
Greater capacity: The underground storage bin has a capacity 10 to 20 times that of traditional trash cans, significantly reducing the frequency and cost of collection.
Environmentally friendly: Reduces the frequency of garbage trucks' passage, decreases noise, exhaust emissions and traffic disturbances
Safe and convenient: The height of the discharge port is moderate, making it easy for people of all ages to use, and there is no risk of tripping.
Intelligent Management: Equipped with sensors, overfill alarm and remote monitoring, achieving refined operation management.
Climate adaptation: unaffected by extreme weather conditions, able to operate normally even in harsh environments such as snowy or rainy conditions.
Applicable Scenarios
High-density urban residential areas, commercial zones and public spaces.
Crowded places with high foot traffic such as airports, railway stations, and sports venues.
Areas with high requirements for landscape such as parks and scenic spots.
Places with strict requirements for hygiene conditions such as schools and hospitals.
New urban areas and urban renewal projects, as supporting facilities for modern infrastructure.
Working principle
Core structure: Composed of underground storage units, automatic lifting system, ground discharge ports and intelligent control system.
Work process:
Residents discard garbage through the ground discharge ports, and the garbage directly falls into the underground large-capacity storage bin.
When the storage bin is nearly full, the sensor sends a signal to alert for clearance.
During the cleaning process, the trash cans are lifted to the ground through a hydraulic/mechanical lifting system, making it convenient for the garbage truck to transport them.
Some of the higher-end models are equipped with compression devices and deodorization systems, which enhance storage efficiency and hygiene standards.
Product Components
Ground discharge unit
Disposal Area / Disposal Station: The entrance where residents discard their garbage. Usually, multiple disposal areas are set up according to different types of garbage classification.
Disposal platform: Provides operational space, facilitating the disposal by various groups of people
Classification identification system: Guides correct classification of garbage for disposal, including graphic and textual signs, audio prompts, etc.
Safety protection device: Prevents children from entering, pets from entering and garbage from overflowing.
Underground storage and lifting unit
Underground storage container / buried box: The core storage component, with a capacity usually ranging from 3 to 12 cubic meters
Lifting mechanism: Elevates the underground storage container to the ground for easy removal
Compression device: Compresses the garbage to enhance storage efficiency
Concrete well / foundation pit: Fixed and protects the underground components, providing an installation base
Intelligent Control and Assistance System
Overflow sensor: Monitors the amount of garbage filled in real time and sends an alarm signal when it approaches full capacity.
Control system: Controls functions such as lifting, compression, and sealing, and supports remote monitoring.
Deodorization system: Eliminates the odor of garbage and improves the quality of the surrounding environment.
Drainage system: Discharges the accumulated water in the bin to prevent leakage of sewage.
Lighting system: Provides lighting for night-time dumping and maintenance.
Fire and safety system: Prevents fires and accidents.

Feature
Material and Appearance
This product is made of high-quality engineering-grade materials - carefully selected high-grade electrolytic galvanized steel plates. It ensures excellent durability while achieving a lightweight design. The surface is treated with outdoor-grade plastic powder through high-temperature electrostatic spraying, forming a long-lasting protective coating. It has outstanding anti-peeling, UV resistance and weather resistance properties, and can adapt to complex outdoor environments.
Function Design
Install clearly labeled classified disposal bins, and use intuitive guidance to help users accurately sort and dispose of garbage, thereby enhancing the convenience and standardization of garbage classification.
Durability and sustainability
Designed specifically for the waste collection needs of various public scenarios, it enhances operational efficiency through standardized classification processes and contributes to environmental sustainability.
Color coding and identification system
The classification bin labels feature a highly visible design, with UV resistance and wear resistance properties, and offer multiple color options. The label color can remain bright and clear for over three years, ensuring long-term effective guidance.


Work Process
Ground Waste Input
Residents put classified waste into closed ground input ports with classification signs. These ports are usually set up in residential areas, commercial streets and other areas, which are convenient for people to use and can effectively prevent waste exposure.
Underground Conveyance
The waste is transported to the underground central collection station through negative pressure pneumatic technology or buried box-type conveying system. The negative pressure pneumatic system uses air pressure difference to transport waste in a closed pipeline, with high efficiency and no secondary pollution; the buried box-type system uses closed boxes for transportation, which is suitable for areas with relatively small waste volume.
Underground Storage & Treatment
After the waste is transported to the underground central station, it is automatically sorted and stored in different containers according to its type. At the same time, the system will compress the waste to reduce its volume, which not only saves storage space but also facilitates subsequent transportation.
Sealed Transfer
The compressed waste is transported to the terminal treatment site by sealed transfer vehicles, avoiding waste leakage and odor diffusion during transportation.
