Underground Waste Classification System is a waste management facility that facilitates waste sorting, underground storage, and convenient collection. The surface features only color-coded sorting slots corresponding to different waste types. Below each slot is a sealed underground storage compartment equipped with separate waste bins and a lifting mechanism. Each slot is labeled with the corresponding waste type to guide accurate sorting.
The underground sealed storage reduces odors and insect problems caused by exposed waste, while saving surface space. During collection, the lifting mechanism raises the underground bins to the surface, reducing the workload of manual collection.

Product Advantage
Structural Design: Only the sorting and disposal openings of the trash cans are visible above ground; the main body of the bins is concealed in an underground storage compartment. A lifting device is also included, allowing the trash cans to be raised during collection without manual excavation.
Sorting Function: Each color-coded disposal opening is labeled with a corresponding trash icon, guiding accurate sorting.
Practical Advantages: It saves ground space, keeps the environment cleaner, and reduces odor and insect problems caused by exposed trash.
Rainwater infiltration and odor control: The underground facilities are highly sealed, effectively preventing rainwater from mixing with garbage and producing leachate. Simultaneously, the ventilation system treats odors, minimizing the impact on surrounding residents.
Convenience and privacy: Residents can dispose of garbage simply by going downstairs, eliminating the need for long-distance transport. The underground design also avoids visual and olfactory disturbances during garbage collection, enhancing living comfort.
Suitable for high-density communities: In densely populated urban core areas, underground systems can more efficiently handle centrally generated garbage.
Features
Sorted Disposal: Multi-colored disposal chutes enable source sorting of waste, ensuring different types of waste enter their corresponding underground containers.
Underground Storage: Utilizing a concrete underground space and wheeled trash cans, waste is stored in a sealed, categorized manner, reducing odor and visual pollution.
Lifting and Transfer: A cross-type lifting platform adjusts the height of the trash cans to accommodate surface collection vehicles, improving loading and unloading efficiency.
Surface Collection: A surface parking area supports the parking of transfer vehicles, facilitating the cycle of full bin emptying and empty bin return, ensuring continuous system operation.
Structural Composition
Product Components
Ground Module
Three dedicated waste-sorting drop-off openings are installed, each corresponding to a specific type of waste. These openings are fitted with foot-activated opening mechanisms and marked with clear sorting icons to guide accurate waste classification.
Boasting an ultra-compact footprint, this module is ideally suited for public areas including residential compounds and city parks.
Underground Module
Aligned with the ground-level drop-off openings, the underground sorting bins typically have a capacity of over 1100 liters each, which is sufficient to hold the daily waste output of small-scale communities (with a population of around 1000–1500 residents).
Equipped with a hydraulic lifting system, the fully loaded underground bins can be lifted entirely to the ground surface, streamlining the waste collection process.
The underground pits housing the bins have been treated with anti-leakage and deodorization solutions, effectively preventing contamination from waste leachate and the spread of unpleasant odors.

✨Material & Appearance
Utilizing premium engineering-grade materials—specifically high-quality electrolytic galvanized steel sheet—it achieves an ideal balance between superior durability and lightweight design. The surface is treated with outdoor-grade plastic powder high-temperature electrostatic spraying, forming a long-lasting protective coating with excellent peel resistance, UV protection, and durable weather resistance.
⚙️ Functional Design
Equipped with clearly labeled sorting compartments, providing intuitive guidance for users to facilitate accurate waste sorting and proper disposal.
️ Durability and Sustainability
Designed for reliable waste collection in various public settings, it improves operational efficiency and promotes environmental sustainability through standardized waste sorting processes.
Color Coding and Identification
The sorting compartment labels feature a highly visible design, are UV-resistant and abrasion-resistant, and offer multiple color options. The label colors maintain their vibrancy and clarity for over three years.


Work Process
Sorted Waste Disposal: Residents deposit different types of waste into the corresponding blue, green, and gray sorting slots on the ground. The waste will fall into the corresponding underground bins for temporary storage.
Full Bin Trigger: When the underground sorting bins are nearly full, the system triggers a lifting operation.
Lifting and Transfer: The underground lifting device activates, raising the full sorting bins to the ground.
Garbage Truck Collection: A garbage truck connects to the raised bins and transfers the sorted waste into the truck for collection.
Reset for Submission: Empty sorting bins are lowered back to their original underground positions via the lifting device, awaiting the next round of waste disposal and collection.
