Mobile Toilet Environmental Labeling Products
Environmental labeling products in mobile toilets must meet the HJ 1160-2021 standard, titled 'Technical Requirements for Environmental Labeling Products - Sewerless Sanitation Systems'. This standard is a specialized environmental protection standard formulated for zero-emission products in scenarios without access to sewer networks. It is applicable to the environmental labeling certification of products in sewerless sanitation systems. The following provides an explanation from three aspects: the scope of application, core requirements, and the significance of certification:
The scope of application is clearly directed at sewerless scenarios
The HJ 1160-2021 standard specifically targets sewerless sanitation systems such as mobile toilets and ecological toilets that cannot be connected to municipal sewer networks. It covers the entire lifecycle of product design, production, use, and waste disposal. These products are typically used in scenarios lacking centralized sewage treatment facilities, such as scenic spots, temporary event venues, and remote areas. Their core objective is to achieve zero pollutant emissions and prevent pollution to soil, water bodies, and other environmental elements.
Core requirements focus on resource recycling and pollution control
The standard sets specific indicators in three aspects: resource utilization efficiency, pollutant emission control, and material environmental friendliness:
- Resource recycling: Products are required to have the function of recycling feces and urine resources. For example, technologies such as biodegradation and membrane separation are used to convert excreta into organic fertilizer or reclaimed water, achieving efficient recovery of water resources and nutrients.
- Pollution control: Strict limits are placed on odor emission concentrations (e.g., ammonia ≤ 0.5 mg/m³, hydrogen sulfide ≤ 0.03 mg/m³), and efficient deodorization systems are required. Additionally, solid waste must be sealed and collected for regular removal to prevent secondary pollution.
- Material environmental friendliness: The use of materials containing heavy metals and harmful substances is prohibited. Priority is given to the selection of degradable or recyclable materials to reduce the environmental impact throughout the product's lifecycle.
The significance of certification reflects environmental orientation and market value
Products that pass the HJ 1160-2021 certification can obtain an environmental labeling mark, indicating their compliance with national environmental protection policy guidelines and helping to enhance market competitiveness. For users, choosing certified products means opting for a lower-carbon and more sustainable sanitation solution. For the industry, this standard promotes technological upgrades in mobile toilets and facilitates the development of resource-recycling environmental protection industries.
