[Case Study] Resolving Grease Clogs & Odors with Grease Ozonizer | Yakiniku Restaurant
CASE STUDY: Restaurant / Yakiniku (BBQ) Restaurant (Oyama, Tochigi)
Powerfully Decomposing Stubborn Grease Clogs and Severe Odors with Ozone.
Drastically Reducing Grueling Cleaning Tasks from Over Once a Week to “Once a Month."
Equipment Installed: AIC Grease Ozonizer®
■ Pre-Installation Challenges: Frequent Grease Clogs and the Grueling Burden of Cleaning More Than Once a Week
“Ushiya no Segare" is a popular Yakiniku (Japanese BBQ) restaurant in Oyama, Tochigi. Due to the nature of a Yakiniku restaurant serving high-quality Wagyu beef, an exceptionally large volume of grease flows into the kitchen’s grease trap, causing frequent pipe clogs. In addition to creating an environment prone to severe odors, staff were forced to clean the grease trap at a high frequency of “more than once a week" as a countermeasure. This had become a significant operational burden and a major source of stress for the restaurant staff.
⚠️ Severe On-Site Challenges
- Frequent Grease Clogs and Odors: Plumbing troubles and hygiene concerns caused by massive amounts of grease buildup.
- Grueling Cleaning Tasks: Heavy physical labor required more than once a week to deal with odors and grease.
- Operational Hindrance: After-hours cleaning tasks creating a massive burden on the staff.

■ Reason for Selection: Experiencing the Overwhelming “Grease Decomposing Power" of Ozone Through a Live Demo
Initially, they were highly skeptical, wondering, “Can a machine really eliminate grease and odors on its own?" Therefore, we installed a demo unit in their actual commercial kitchen to conduct a live operational test.
The result: the powerful oxidizing power of ozone visibly decomposed the grease within the grease trap, and the severe odors that had been plaguing them completely vanished. Witnessing this “dramatic effect on their actual factory floor" with their own eyes became the deciding factor, leading to an immediate decision to install the system.
■ Post-Installation Results: Odors and Clogs Eliminated, Cleaning Frequency Plummets to “Once a Month"
After installation, their long-standing struggles with foul odors and stubborn grease blocks in the grease trap were beautifully resolved.
Because ozone automatically decomposes and liquefies the grease every day, the grueling cleaning routine that used to occur more than once a week plummeted to “about once a month." The cleaning process itself became incredibly simple, dramatically improving the working environment for the staff. The client reported being highly satisfied, stating, “We are so incredibly glad we were able to solve our grease trap problem."

Feedback & FAQ from Restaurant Owners
Specialist AIC Insights: Fundamentally Solving “Grease and Odor" Problems in Restaurants
In commercial kitchens handling massive amounts of animal fats (like lard), such as Yakiniku restaurants, simple water purifiers or bacteria alone cannot keep up with decomposition, leading to pipe clogs and overpowering odors.
Grease trap cleaning is one of the most burdensome tasks for restaurant staff. “Physical grease liquefaction and deodorization" using ozone is “the most reliable capital investment"—one that not only dramatically improves the hygienic environment but also directly translates to more efficient restaurant operations and higher staff retention rates.
