Underground waste compaction equipment is a sanitation facility that places the waste compression equipment and storage bins underground, retaining only the surface operation and feeding port. Its core function is to reduce waste volume and seal it for storage through mechanical compression.
Underground waste compaction equipment mainly consists of four parts: the underground compression and storage body, the surface feeding device, the hydraulic control system, and the deodorization and ventilation system. Its initial design purpose was to solve the problems of traditional waste stations, such as large surface space occupation, odor diffusion, and visual pollution. Currently, it is widely used in centralized waste treatment in densely populated urban areas.

Customized Waste Compactor Solutions
Core Technology by RNKJ
Key Features
Waste Compatibility: Processes semi-wet, wet, and solid waste materials.
Capacity Range: 6–20 m³ (4.5–25 tonnes).
Integrated Lifting Platform: Ensures efficient loading and compaction.
Hook-Arm Truck Compatibility: Seamless integration with standard waste transport systems.
Liquid-Containment Design: Prevents leakage during operation.
Target Applications
Large-scale commercial and industrial facilities including:
Supermarkets • Shopping Malls • Food Markets • Hospitals • Restaurants • Agricultural Sites • Food Processing Plants
Product Advantage
High space utilization: Core equipment is buried underground, requiring only a feeding port and operating pavilion on the ground. The saved ground space can be planned as green areas or public activity areas.
Minimal environmental impact: The fully sealed structure effectively blocks garbage odors, leachate, and flies. Combined with a deodorization system, it significantly reduces pollution to the surrounding environment.
Low transportation costs: Compressed garbage reduces its volume by 50%-70%, decreasing the frequency of garbage truck transport and lowering fuel consumption and transportation noise.
Features
Fully Sealed Design: The entire process, from feeding and compression to storage, is sealed to prevent direct contact between waste and the external environment.
Intelligent Control: Automatic compression, full-bin alarm, and remote monitoring are achieved through a PLC control system, reducing manual operation.
Leak-Proof Treatment: The underground silo is constructed with corrosion-resistant and leak-proof materials, and is equipped with a leachate collection system to prevent soil and groundwater contamination.

Workflow
Waste Disposal: Sanitation workers or residents pour waste into the underground storage bin through the ground-level inlet.
Automatic Compression: When the waste in the bin reaches the set volume, the hydraulic system activates, and the compression plate squeezes the waste to reduce its volume.
Waste Transportation: After compression, the transportation truck connects to the underground bin via a special docking device, directly loading the compressed waste blocks into the truck body.
Station Cleaning: After transportation, the system automatically performs high-pressure washing of the bin and activates the deodorization equipment to complete the station cleaning.

Application Scenarios
Urban Central Areas: Suitable for commercial districts and office building clusters with limited land resources and high population density.
High-Density Residential Areas: Capable of meeting the centralized waste disposal needs of large communities while minimizing disruption to residents' lives.
Key Control Areas: Prioritized for areas with high requirements for environmental cleanliness, such as scenic spots, hospitals, and school perimeters.
