Key Achievements: Solved diaper odor issues and eliminated the risk of in-facility infections.

■ Challenges Before Installation: The Shift to “In-Facility Disposal" and Universal Infection Risks

Historically, many Japanese nursery schools required parents to take their children’s used diapers home—a practice that often caused severe odor issues in their cars and daily lives. However, as government guidelines shift toward disposing of diapers on-site (the global standard), our facility faced a new, universal challenge.
Since waste collection is not daily, the extended in-facility storage time raised significant hygiene concerns. We were deeply worried about the potential for airborne odors and in-facility infections, such as secondary Norovirus outbreaks, spreading from the storage area.

⚠️ Key Challenges at the Time

  • Managing the Transition: Eliminating the burden on parents by safely handling diapers on-site.
  • Fear of Infectious Diseases: The universal risk of viral spread and secondary infections from long-term diaper storage in the facility.
  • Psychological Toll on Staff: The constant stress of handling and storing contaminated waste while worrying about infection risks.

Site Characteristics:
In childcare settings globally, children have developing immune systems, making thorough infection control mandatory. Conventional plastic bags simply cannot prevent the leakage of odors and viruses during on-site storage.

■ The Deciding Factor: A “Special Film" That Blocks Viruses and a Safe “Non-Vacuum" Seal

“How can we store them safely without leaking odors?"
While searching for a solution, the client discovered Ecomshuu on the AIC website and decided to try it. Initially, they imagined a “vacuum-packing machine." However, they were deeply convinced by our explanation: “Creating a vacuum can dangerously draw air containing viruses and foul odors out of the diaper. That’s why Ecomshuu uses a gentle [wrapping seal] without extracting air."
The primary deciding factor for our implementation was this specialized film material. It completely blocks viruses, significantly reduces unpleasant odors, and is so incredibly durable that once sealed, it can only be cut open with a blade.

■ Results After Installation: Freedom from Odors and Infection Fears, Creating an Environment Focused on Childcare

After introducing Ecomshuu, parents were thrilled, saying, “The awful smell in the car on the way home is gone!" They deeply appreciate and empathize with the school’s commitment to improving their daily lives. Even now that disposal is handled at the facility, there is absolutely no noticeable odor during long-term storage, and the reduced infection risk means we don’t have to strictly limit the storage location.
As an unexpected bonus, it has been incredibly useful for handling clothes soiled by vomit. Caregivers can lightly wash the clothes and seal them directly in the pack. Since the special film does not stick to the fabric, parents can easily open it with scissors at home and wash it immediately. The convenience of returning items as-is has been highly praised.

  • Establishment of Hygiene Management: The virus-blocking material has eliminated staff fears of infection, leading to greater peace of mind.
  • Reduced Burden on Parents: The stress of awful odors during diaper transport is gone, enhancing trust in the facility.
  • Improvement in Childcare Quality: With less stress surrounding hygiene management, caregivers can focus entirely on their primary duty: caring for the children.

■ AIC’s Perspective

[Industry Topics] Reducing the Burden on Childcare Settings and Promoting “In-Facility Diaper Disposal"

To reduce the burden on childcare workers and improve convenience for parents, the Ministry of Health, Labour and Welfare strongly recommends the in-facility disposal of “used disposable diapers," which were previously often taken home. Subsidies and support are expanding for this initiative. In modern childcare facilities, in-facility diaper disposal is becoming a prerequisite for being a “school of choice."

As in-facility diaper disposal advances, the most significant challenges facilities face are “odors during storage" and “the risk of secondary in-facility infections like Norovirus."

Like the nursery school in Kanagawa Prefecture, installing Ecomshuu to “It completely seals away viruses and suppresses odors to the absolute minimum right at the source." makes perfect sense. It acts as a “safety device" to protect not only the children but also frontline staff from infection risks.

The technology of gently wrapping rather than vacuum-packing is based on advanced knowledge aimed at preventing the airborne spread of invisible viruses. Providing parents with peace of mind and creating an environment where staff can focus on “essential childcare duties" without the stress of hygiene management is the ultimate value of installing Ecomshuu.

Customer Voices & Q&A


Historically, it was common in Japan for parents to take used diapers home, but there has been a significant shift toward on-site disposal to reduce the burden on families. Our main goal was to manage this transition smoothly by eliminating odors during storage and, most importantly, neutralizing the universal risk of secondary in-facility infections like Norovirus.

Creating a vacuum is risky because it can forcefully draw air containing viruses and foul odors out of the diaper and into the room. Ecomshuu uses a gentle “wrapping seal" that contains everything without extracting air, completely preventing viral dispersion. The resulting pack is so durable it cannot be torn without a blade, ensuring absolute hygiene.

Yes. It is highly effective for handling clothes soiled by vomit. Caregivers can lightly wash the garments and seal them directly in the pack to return to parents. Since our special film does not stick to the fabric, parents can easily open the pack at home and wash the items immediately, which has been a highly appreciated feature.
