Reducing Waste and Recycling Resources

With the aim of using water efficiently, we treat rainwater, kitchen wastewater, and other wastewater generated at the terminals. The resulting gray water is then reused for flushing toilets.

Using microorganisms that exhibit high processing capacity at room temperature, disposers repeatedly stir and spray water on waste for a set period of time to break it down into ammonia water and carbon dioxide gas. With almost no residue left at this stage, the waste is discharged into sewers (or purification facilities)within about 24 hours, and is treated as gray water at wastewater treatment facilities. In addition to reducing CO2 emissions by incinerating food waste,treated water is reused for flushing toilets.

To help address international challenges such as marine plastic pollution, the retail stores and restaurants operated by our Group have started using environmentally-friendly materials. Our retail stores have adopted Bio LIMEX shopping bags made from limestone and plant-derived resins. In our restaurants, we are reducing the consumption of plastic by transitioning to paper straws or discontinuing their provision altogether.
