Sichuan New Type Mobile Toilet

Sichuan's new-type mobile toilets focus on intelligent, eco-friendly, and diversified innovations, achieving remarkable progress in technological applications and scenario adaptations.

I. Intelligent Upgrades Enhance User Experience
Some regions in Sichuan have implemented smart management of mobile toilets through IoT technology. For example, smart guidance screens are installed near Chengdu subway stations to display real-time toilet occupancy, reducing user waiting times. Mobile apps allow users to check the locations and availability of nearby mobile toilets, improving search efficiency. The newly added mobile toilets for the 2025 Chengdu Universiade further integrate intelligent sensor-based flushing systems, automatically triggering flushes via infrared or pressure sensors to avoid contact contamination. Remote monitoring systems continuously track facility operations, such as water and electricity consumption and equipment failures, enabling timely responses from maintenance staff to ensure hygiene and safety.

II. Eco-Friendly Technologies Drive Low-Carbon Development
For rural tourism and scenic areas, Sichuan has piloted “eco-mobile toilets” that use fecal-sewage separation technology to divide solid and liquid waste. Solids are biologically degraded into organic fertilizers, while liquids are treated for irrigation, achieving wastewater resource utilization. Over 300 eco-friendly mobile toilets in Liangshan and Aba prefectures have adopted this technology, significantly reducing pollution emissions. Additionally, solar power systems provide clean energy for lighting and ventilation, while rainwater harvesting systems collect water for flushing, further lowering water consumption. These green technologies have transformed mobile toilets from “pollution sources” into “ecological nodes.”

III. Diversified Types Meet Varied Needs
Sichuan's mobile toilets are designed in multiple types based on usage scenarios:

• Foam-Sealed Type: Uses a foaming device to generate dense foam that covers waste, eliminating the need for flushing and blocking odors, suitable for eco-sensitive areas like scenic spots and parks.
• Mechanical Packaging Type: Automatically packages waste with biodegradable film through contactless operation, ideal for temporary sites like construction areas and picnics.
• Water-Flush Direct-Discharge Type: Employs high-pressure water flushing for strong cleaning power, commonly used in commercial district renovations or high-traffic areas.
• Simple Single-Squat Type: Features a simple structure and low cost (about 2,500 yuan per unit), enabling rapid deployment for temporary events or emergencies.

Through technological innovation and scenario adaptation, Sichuan's new-type mobile toilets not only elevate public sanitation services but also provide sustainable solutions for rural revitalization, green tourism, and large-scale event support.
