Zhongyunhui Mobile Waterless Toilet

Zhongyunhui Mobile Waterless Toilet is a non-sewered sanitation toilet developed by Zhongyunhui (Chengdu) Technology Group Co., Ltd. based on the ISO 30500 international standard. It utilizes microbial degradation and vacuum negative pressure technology to achieve fecal resource utilization, environmental protection, energy conservation, intelligent management, and flexible layout, becoming a benchmark product in the field of waterless ecological public toilets.

Technical Principles and Core Advantages
This toilet breaks free from dependence on water and electricity through microbial degradation and vacuum negative pressure technology. Microorganisms accelerate the decomposition of organic matter under the action of enzyme activity, converting fecal matter into organic fertilizer; the vacuum negative pressure system reduces odor diffusion and enhances treatment efficiency. Its advantages are reflected in four aspects:

1. Environmental Protection and Energy Conservation: A single toilet unit saves 2,000 tons of water annually. Fecal matter is converted into organic fertilizer through high-temperature fermentation, reducing carbon emissions by 12.6 tons per year, equivalent to planting 200 trees, significantly lowering resource consumption and carbon emissions.
2. Intelligent Management: Equipped with the self-developed Zhongyunhui Universal Internet of Things operating system, it can remotely monitor microbial activity, temperature, humidity, and usage frequency within the degradation tank. When degradation efficiency fluctuates, the system automatically alerts and adjusts temperature control strategies, reducing manual intervention.
3. Flexible Layout: There is no need to excavate roads for pipeline installation, and the installation period is shortened by 60% compared to traditional methods. For example, the public toilets at Chengdu's express bus stops K6/K7 were fully assembled in just 7 days, making them suitable for complex scenarios such as tourist attractions and transportation hubs.
4. Odor-Free Space: Through an IoT sensor matrix, it continuously monitors eight types of air quality indicators and automatically activates photocatalyst + plasma deodorization devices. The ammonia concentration inside the toilet is stably controlled at ≤10μg/m³, meeting the air quality standards of maternity rooms.

Application Cases and Market Position
In August 2026, multiple Zhongyunhui mobile toilets were used at a large-scale outdoor theme event in Chengdu, with each unit serving hundreds of people daily. Excreta decomposed in a closed environment, and the contents of the degradation tank at the end of the event were close to dry organic fertilizer, directly usable for greening. Additionally, successful applications have been made in Chengdu's Longquanyi District and the high-tech campus of Leshan People's Hospital. Currently, Zhongyunhui has achieved the top position in both national urban coverage and market size in the field of waterless ecological public toilets, becoming a new industry benchmark.
