[Mr. Gima] Restaurants in the food service industry have decided to separate the large amounts of wastewater they produce every day into a drainage layer called a Grease Shield, separating the residue and oil before discharging it. The previous drainage layer had safety, hygiene, and odor issues, and the gap between the dining area and the drainage layer created by burying it inside the kitchen placed a strain on employees.

To address these issues, we introduced the Grease Shield System, a compact, easy-to-operate automatic cleaning device that separates the residue and oil. We plan to roll this out to other companies in the future.

While the residue is discarded, the oil is recycled into hand-washing detergent for use in our stores, which we plan to start using soon.

[Mr. Yoneda] We believe that the SDGs are a major challenge that will lead to a transformation of the economic structure. Saizeriya supports the "3R + Renewable" concept and will incorporate it into its procurement policy.

For example, in February 2020, we began switching straws to biomass and PLA products, working to reduce the use of petroleum-based plastics. We also consider replacing broken and discarded glassware with Tritan products, which we consider to be a significant achievement.

Similarly, based on our commitment to resource conservation, we began introducing wooden tableware, which is less likely to break, in March 2021.

Since 2017, we have been collecting discarded metals from our stores and have recycled a total of 37 tons of aluminum to date. For reuse, we have been reusing unused ceramic tableware both domestically and internationally for the past two years, reusing 50 tons of tableware.

[Mr. Yoneda] We started introducing new Tritan™ tableware in 2018. At that time, we discussed the idea of ​​reusing these when they became unusable. Tritan™ is a shatter-resistant material, but unfortunately some pieces become unusable due to scratches. As the amount was small, we started recycling them about a year later in 2019.

[Mr. Yoneda] We use them as slip holders. We chose them as products that customers would see, hoping that they would help raise awareness of our recycling efforts. We are also considering using recycled Tritan™ for trays, plates, and other items in the future.

[Mr. Yoneda] Initially, the motivation for introducing Tritan™ was to ensure safety and security for customers and reduce the workforce of employees, but even back then, employees had expressed the opinion that it was a waste to throw away unwanted glassware. I think that using resources effectively, as in this case, is easy to understand and will be well received. In addition, although it's not just Tritan™, each store needs to stockpile items for recycling until spring and autumn, and employees are highly conscious of recycling and proactively taking action. (Incidentally, since the introduction of Tritan™, there hasn't been a single injury caused by broken tableware.)
