Biodegradable Outdoor Mobile Toilet

The main type of biodegradable outdoor mobile toilet is the microbial degradation mobile toilet, which efficiently decomposes excrement through microbial strains, achieving the goals of water-free flushing, no discharge, and no pollution. The following provides an introduction from three aspects: technical principles, brand prices, and other related types.

Technical Principles of Microbial Degradation Mobile Toilets
The core components of this type of toilet include a fermentation degradation tank, microbial strain carriers, mechanical transmission devices, and a PLC constant temperature and humidity control system. After excrement falls into the fermentation degradation tank through the squat toilet, it mixes with the pre-added microbial strains and carriers. The mechanical transmission device drives the agitator to rotate forward and backward, ensuring full contact between the excrement and the strains, and accelerating decomposition under constant temperature and humidity conditions. The decomposition products are mainly达标 gases such as carbon dioxide and water vapor, which are discharged through exhaust pipes; the remaining residue is minimal and can be regularly cleaned up or further processed. Its advantages include:

• Environmental Protection and Energy Efficiency: No water flushing is required, with a daily power consumption of only 3-5 degrees (depending on the number of users and local temperature), and no sewage discharge, reducing environmental pollution.
• Wide Applicability: Not restricted by temperature, it can be used in extreme environments such as high cold and arid regions, making it suitable for a wide range of areas.
• Convenient Maintenance: Depending on the number of users, the strain replacement cycle is 3-6 months. The cost of domestic strains is about 300 yuan per toilet seat, and imported strains are about 500 yuan per toilet seat. It requires no sewage removal and has no odor.
  This technology has been included in the National 863 Program, with related products passing safety inspections and applying for multiple patents, forming a standardized production system.

Brands and Prices of Biodegradable Mobile Toilets
Mainstream brands in the market include Muda, Jintongchuang, Lvzhu Mengxiang, Sailina, Gerunsi, Heyue Metal, etc. Prices vary greatly depending on specifications, configurations, and regional differences:

• The outdoor waterless ecological degradation public toilet produced by Cangzhou Pulin in Hebei ranges in price from 1,800 yuan per unit to 4,500 yuan per seat;
• The scenic microbial degradation mobile toilet from Sichuan Gerunsi Environmental Protection Equipment Co., Ltd. costs up to 6,000 yuan per unit;
• The outdoor degradation-type environmental protection restroom from Ningxia Sailina Transportation Facilities Co., Ltd. is priced at 5,000 yuan per unit;
• The biodegradable mobile toilet from Hunan Changsha Rongdong Environmental Protection Engineering Co., Ltd. is priced per square meter, with a unit price of 800 yuan per square meter.
  Price differences mainly stem from materials, capacity, and additional features (such as wind and rain protection design).

Other Related Types of Biodegradable Toilets
Some mobile toilets adopt mechanical foot-pedal packaging technology, equipped with 304 stainless steel squat toilets and biodegradable packaging bags. Excrement is directly sealed into the packaging bag through a mechanical foot-pedal action, requiring no water flushing and being odor-proof, suitable for scenarios such as civil air defense projects and park scenic areas. This type of toilet is mobile and flexible, but requires regular replacement of packaging bags, with maintenance costs depending on usage frequency.
