In nursery schools where young children with developing immune systems gather, the “hygiene management of food waste" generated daily from the kitchen is a critical issue. Storing food waste on the premises until collection leads to foul odors, pest infestations, and infection risks, significantly deteriorating the facility’s sanitary environment.

While many facilities introduce “composting food waste disposers" as part of their eco-friendly and food education initiatives, they often face new sources of stress: “excess compost with no use" and “the heavy labor of daily residue removal." Consequently, a never-ending number of facilities abandon their operations. This page introduces a case study of a nursery school in Hokkaido where the system operates stably even in severe cold, solving both hygiene and compost disposal problems.

Three Pitfalls When Choosing Disposers for Childcare Facilities

1. Odors, Pests, and Infection Risks from “Storing Food Waste" on the Premises

Storing food waste in an on-site garbage area for several days until the collection contractor arrives not only creates a breeding ground for foul odors and fruit flies but also encourages the proliferation of food poisoning bacteria. In childcare environments where cleanliness is the top priority, the mere act of storing garbage poses a massive hygiene risk.

2. The Stress of “Residue Removal" and “Excess Compost" from Composting Machines

Facilities that have previously installed composting processors inevitably face the “troublesome residue removal tasks" requiring periodic scraping, and the “disposal of massive amounts of finished compost." Because the school’s vegetable gardens and flower beds simply cannot use it all, facilities often end up paying industrial waste fees to dispose of it, only adding to the burden on the kitchen staff.

3. Anxiety over “Poor Decomposition and Operational Halts" in Sub-Zero Environments

In freezing climates like Hokkaido, standard bio-processors fail to maintain internal temperatures, causing microbial activity to halt and food waste to putrefy. “Can it process waste flawlessly even in winter?" is an absolute selection criterion for facilities in northern regions.

Why the Extinction-Type GOMISER® is the Optimal Choice for Childcare Facilities

The fundamental solution to these challenges is the “Extinction-Type Food Waste Disposer (GOMISER®)," which breaks down food waste entirely into water without leaving any residue. Here is why a never-ending number of facilities switch from composting types to the GOMISER.

[Reason 1] No Residue Removal Required (Complete Extinction-Type)

The GOMISER is an extinction-type system that uses microbial power to break down food waste into “water and carbon dioxide." Unlike composting types, there is absolutely no heavy labor involving shoveling out residue. You simply press a button and toss the waste in, completely freeing kitchen staff from troublesome maintenance.

[Reason 2] Can Be Used as “Liquid Fertilizer" Only When Needed

There is no need to worry about storage space for massive amounts of compost. The processed water from the GOMISER can be safely discharged into the sewer (grease trap), but because it is nutrient-rich, diluting it turns it into high-quality “liquid fertilizer." You can hygienically utilize only the amount you need for the school’s gardens and flower beds.

[Reason 3] Stable Operation Even in Freezing Hokkaido

The GOMISER® features a temperature control function to maintain microbial activity. Even in the harsh winters of Hokkaido where outside temperatures drop below freezing, it maintains the internal temperature so microorganisms can work actively, demonstrating stable processing capabilities year-round.

Hokkaido Nursery School Case Study & Customer Voice

GOMISER installed in Hokkaido

“We introduced the extinction-type food waste disposer to enhance hygiene. Being able to process food waste immediately without having to store it makes our facility highly sanitary.

In the past, we used a composting type, but removing the residue was a hassle, and we struggled with storing and utilizing the compost. I love that the GOMISER’s discharge can serve as liquid fertilizer, allowing us to use it only when needed."

Frequently Asked Questions from Cold-Climate Facilities

Yes, it operates flawlessly. The GOMISER features an excellent heat-retention structure designed for cold regions. Furthermore, the microorganisms that break down the food waste generate their own fermentation heat (self-heating). This allows the unit to properly maintain internal temperatures and deliver stable processing capacity year-round, even in harsh winter environments where outside temperatures drop below freezing.

Yes, it is completely unnecessary. The GOMISER is an extinction-type processor that completely breaks down food waste into “water and carbon dioxide." There is no heavy labor involved in periodically scraping out and disposing of the contents with a shovel, as is required with composting types. For the kitchen staff, the entire process is completed simply by tossing the food waste in.

There are absolutely no troublesome tasks. You can throw the food waste in directly without draining the water first. After that, it performs stable processing and decomposition fully automatically. No special maintenance is required; daily upkeep involves nothing more than lightly rinsing the inside of the unit with water.

Please rest assured. The GOMISER produces almost no foul odors. The primary cause of foul odors is the “putrefaction of food waste." Because the GOMISER uses microbial power to rapidly break down and extinguish the waste before putrefaction can begin, it fundamentally prevents odor leaks to neighbors and the breeding of flies and pests. We have a proven track record of flawless operation in restaurants and nursery schools located within residential areas.
