[A Facility Dedicated to Advanced Hygiene Management]
Food Processing Plant (Tofu Manufacturer)
Location: Shiga Prefecture
This facility specializes in the manufacturing and processing of tofu. They faced a significant challenge in managing large volumes of food loss and manufacturing residue—particularly high-moisture, off-spec “waste tofu"—inevitably generated during their daily operations.
In food processing plants requiring strict hygiene management based on HACCP and other standards, processing these high-moisture residues quickly and cleanly is the foundation of safe and reliable production. This plant opted for the highly logical approach of “immediate elimination at the source," ensuring waste never lingers on the factory floor, thereby maintaining a pristine manufacturing environment.
■ Pre-Installation Challenges: The Barrier of High-Moisture Residue and the Limits of Hygienic Storage
[Site Characteristics] High-moisture waste tofu decomposes extraordinarily fast. Storing it long-term as industrial waste within a food processing plant inevitably creates a breeding ground for severe odors and pest infestations.
Previously, to resolve their food waste issues, this plant had conducted practical tests with a competitor’s waste elimination machine. However, the machine’s decomposition capacity could not keep up with the specific moisture content and composition of waste tofu. They were forced to abandon the installation simply because the machine “could not fully process the load."
As a result, they had no choice but to continue storing the waste inside the plant until industrial waste collectors arrived. The odors and pests generated during this waiting period became a massive source of stress and a major compliance concern for employees committed to maintaining strict hygiene standards.
⚠️ Key Challenges at the Time
- Concerns from Competitor Tests: Insufficient processing capacity for high-moisture waste tofu forced them to abandon previous solutions.
- Increased Storage Risks: Severe odors and pest generation caused by retaining industrial waste inside the plant before collection.
- Hygiene Management Concerns: A lack of a fundamental solution to consistently maintain the pristine environment required of a food processing facility.
■ Reason for Selection: Reliable Verification Through Sample Testing and a 1-Month Demo
Given their past experience with competitors’ machines failing to process their waste, the client was understandably cautious. Therefore, rather than pushing for an immediate sale, we proposed a “phased verification process."
First, we asked the client to send us samples of their actual waste for preliminary “processing tests." Following this, we deployed a demo unit to the actual factory floor for one month. This allowed employees to rigorously verify its processing capabilities within their standard daily workflow.
Ultimately, it was proven on-site that GOMISER’s powerful, specialized microorganisms could smoothly decompose waste tofu into water. The ability to “confirm the actual capabilities in advance" became the deciding factor, leading to the official installation of the GH-35 model.
■ Installation & Results: Freedom from Storage Stress and a Cleaner Manufacturing Floor

With the introduction of GOMISER, manufacturing residues like waste tofu can now be deposited and eliminated immediately on-site as they are generated.
This completely eliminated their most pressing challenge—"long-term storage until industrial waste collection day"—and entirely resolved the severe odors and pest infestations that had plagued the plant. The client reported, “We are incredibly glad we could confirm the results with a processing test prior to installation. The odors and pests we were so worried about are completely gone, and we are highly satisfied," expressing strong confidence in the results.
- ✅ Eradication of Odors and Pests: Eliminating waste before decomposition starts removes hygiene risks at their root.
- ✅ No More Storage Space Needed: Eliminating the need to retain industrial waste keeps the backroom impeccably clean.
- ✅ Guaranteed ROI Before Purchase: Rigorous verification using a demo unit ensured a reliable and confident capital investment.
■ AIC Commentary: Expert Insights
In food processing plants, completely decomposing high-moisture food residues (such as waste tofu) with a disposal machine presents technical hurdles that are difficult to evaluate based on catalog specifications alone. As seen in this case study, many companies nearly give up on implementation after testing competitors’ products that ultimately fail to process the load.
[Professional Know-How] Securing “Reliable Capital Investments" in Food Processing Plants
- ✓
The Importance of “Sample Testing" and “Demo Units":
Waste composition, moisture content, and operational workflows vary drastically from plant to plant. Before finalizing any sale, we prioritize a process that involves processing tests using the client’s actual waste and providing on-site demo units. This ensures that employees gain the hands-on confidence and proof that the system will function flawlessly in their specific environment. - ✓
“Odor and Pest Control" as a Prerequisite for HACCP:
GOMISER goes far beyond simply reducing industrial waste disposal costs. By enabling immediate processing at the source, it dramatically elevates the plant’s hygiene standards (pest and odor control), serving as a powerful foundational asset for HACCP compliance.
Plant managers who are wondering, “Can our unique waste really be decomposed?" or who have experienced failures with competitors’ machines in the past, are strongly encouraged to utilize our preliminary processing verification and demo unit loan services.
