[A Facility Dedicated to Creating a Clean Environment]

Social Welfare Corporation Tsukushinbo Nursery School

Location: Hino City, Tokyo
Opened in 1971, Tsukushinbo is a historic, community-rooted nursery school guided by the philosophy, “A healthy mind grows in a healthy body." In addition to fostering a warm environment where “both adults and children can spend every day with a smile and grow together," they strictly enforce safety and hygiene measures.
As part of their commitment to prioritizing the children’s safety, they use the GOMISER to return food waste from school lunches to water. This practice prevents foul odors and pest infestations, ensuring “a clean, eco-friendly facility operation that places no burden on nature." We are proud to support their efforts to protect a healthy and rich environment for future generations with our technology.

■ Before Installation: Municipal Collection Limits and the Drawbacks of Hygienic “Storage"

[Site Characteristics] A childcare facility caring for infants and toddlers. The unhygienic storage of food waste generated from school lunches directly leads to significant risks, including foul odors and pest outbreaks.

Tsukushinbo Nursery School faced a challenging restriction: the municipality severely limits the volume of designated commercial garbage bags they can set out for collection. Because they could not dispose of all the food waste generated from school lunches, it became a daily struggle to store the excess waste on the premises until the next collection day.
Furthermore, the increasingly strict waste collection rules imposed by local governments were placing an immense burden on the on-site staff responsible for storing and managing the food waste. In a childcare facility where hygiene is paramount, fundamentally reducing the volume of food waste was an urgent necessity.

⚠️ Challenges at the Time

  • Collection Volume Limits: The city restricts the number of commercial garbage bags allowed, making it impossible to discard all waste.
  • Storage Burden: The grueling task and hygiene risks of storing uncollected food waste on the premises.
  • Municipal Discrepancies: Increased workload for staff due to the tightening of local government collection regulations.

■ The Decisive Factor: An “Extensive Track Record" Ensuring Safe and Reliable Processing

After calculating the daily food waste output at approximately 30kg, we proposed the GOMISER (GH-35 Model), an extinction-type food waste disposer with the optimal processing capacity.
Among the numerous products available, the most significant factor in choosing the GOMISER was its “extensive track record." The fact that the system is widely operating in facilities requiring the highest safety and hygiene standards—such as nursery schools, educational institutions, and medical facilities—provided a profound sense of security for the nursery, which required foolproof waste management.

■ Installation and Results: Achieving a Seamless Outdoor Retrofit and Freedom from Storage Stress

The GOMISER extinction-type commercial food waste disposer installed outdoors at Tsukushinbo Nursery School.

Because the equipment was to be retrofitted onto an existing building, securing a proper drainage plumbing route was a primary concern during the planning phase. However, based on a meticulous preliminary site survey and design, we successfully completed the installation and plumbing work in an optimal outdoor space.
Following the installation, food waste generated at the facility is now tossed directly into the machine, where it is broken down into water and carbon dioxide. This process entirely eliminated their biggest headache: “the storage of food waste." By fundamentally resolving the issue of strict collection limits, the client has highly praised the system, stating they are “extremely satisfied."

  • Elimination of Garbage Storage: By extinguishing food waste on-site, the stress of putrefaction and foul odors has been reduced to zero.
  • Overcoming Collection Limits: They can now process lunch scraps effortlessly without worrying about designated bag capacities.
  • Successful Retrofit Installation: Implemented proper outdoor plumbing while fully utilizing the existing building structure.

■ AIC Specialist Insights

Across municipalities nationwide, collection rules for general commercial waste (such as volume limits and the implementation of processing fees) are becoming stricter every year. Consequently, many facilities face the severe risk of “storing undiscardable food waste." Particularly in nurseries, welfare, and medical facilities, long-term storage of food waste directly translates to critical hygiene risks, including the generation of foul odors, nuisance pests, and ultimately, infectious diseases.

[Professional Know-How] Regarding “Retrofit Installations" in Existing Facilities

  • Installation is Possible Even in Completed Buildings:
    As demonstrated in this case, we frequently receive inquiries from facilities that are already fully constructed (renovation/retrofitting scenarios). We accurately assess the existing plumbing infrastructure and outdoor spaces to propose an optimal installation route that will not interfere with the facility’s daily operations.
  • Fundamental Risk Elimination:
    The GOMISER, which “extinguishes" food waste on the spot, goes beyond mere cost reduction. It is the most rational and effective capital investment a facility can make to maintain strict hygiene management and environmental compliance.

If your facility is struggling with challenges such as “exceeding municipal collection limits" or “reaching the limit of hygienic waste storage," please feel free to consult with us. From design and installation to after-sales support, our team possesses an extensive track record to assist you.

Customer Voices & Q&A


The volume of commercial garbage bags we could put out for city collection was strictly limited. We were struggling because we simply couldn’t discard all the food waste generated daily from our school lunches.

The immense burden of having to store any food waste exceeding the designated limit on our premises until the next collection day. This, coupled with the increasing workload required to comply with the tightening municipal collection rules, was exhausting.

The proposed model (GH-35) had a proven track record of installations at numerous other facilities. We felt confident that, as a nursery school prioritizing safety, we could trust this system.

Because we were installing it on an existing structure, we needed to carefully plan the plumbing. However, the outdoor installation was completed flawlessly using the optimal route. As a result, our storage dilemma vanished, and we are extremely satisfied.
