Ecological Toilet and Mobile Public Toilet

Ecological toilets and mobile public toilets are public sanitation facilities designed based on new materials and water-saving technologies. They are characterized by water conservation, environmental protection, and mobility, making them suitable for a variety of scenarios.

Diverse Technical Types

• Ecological Public Toilets: Based on solid-liquid separation technology, they achieve harmless treatment of excreta through microbial decomposition. During initial operation, a one-time injection of 70 - 80 kilograms of water is required to maintain microbial activity, followed by features such as water conservation, mobility, and waterless flushing. Modern technology can decompose feces into carbon dioxide, water, and organic fertilizer, and also apply 5G and IoT for remote monitoring.
• Mobile Environmental Protection Toilets: Classified by sewage treatment methods, there are water-flush and waterless suction types, circulating water-flush types, and dry packing types. Circulating water-flush types are equipped with intermittent aerobic and anaerobic sewage treatment devices for feces, adding biological strains and using biofilm technology to accelerate decomposition. The treated water can be recycled for flushing. Dry packing types have waterless flushing devices, where excreta is collected in biodegradable plastic bags, automatically replaced after use, and collected for centralized treatment. Additionally, there are common technical types such as foam sealing, packing, water-saving flushing, waterless rechargeable, and microbial types. Intelligent water-saving ecological and environmental protection toilets can achieve a flushing effect of about 0.46 liters per person by automatically collecting urine and hand-washing water and adding water-saving special agents.

Prominent Structural Features

• Ecological Public Toilets: The toilet body adopts a steel-frame cement composite structure with excellent thermal insulation performance and a service life of over 20 years. Some models are equipped with intelligent temperature control systems, operating at temperatures exceeding 60℃, which also have sterilization and disinfection functions. The carbon-neutral toilets deployed in Chengdu in 2024 have steel-frame structures that can withstand temperatures as low as minus 28℃.
• Mobile Environmental Protection Toilets: The frame is welded from national standard steel, with surfaces covered with anti-corrosion and fire-resistant materials such as color steel plates or carved panels, with a service life of over 20 years. There are diverse choices of exterior wall materials, and the main structure meets the requirements for overall lifting. They come with complete standard configurations and a rich selection of optional configurations, adopting intelligent control systems and thermal insulation systems to achieve low-water-volume flushing effects. The materials used are mostly environmentally friendly panels with recycling value, occupying a small area, having low land dependency, short construction periods, and being reusable.

Wide Range of Application Scenarios

Suitable for scenic spots, alpine and water-scarce areas, public places, service areas, rural areas, etc. In 2022, ecological toilet-related technologies were implemented in 13 venues of the Beijing Winter Olympics, and carbon-neutral toilets were deployed in Chengdu in 2024.
