Bringing about a circular society
Basic concepts
To create a circular society that lives in harmony with nature, we are promoting initiatives such as the reduced use of water and waste, and the effective utilization of resources. In particular, we have set consolidated targets by quantity and intensity for reducing waste and water use, which are social issues, and run PDCA cycles to reduce environmental stress while also striving to improve our recycling rate. We strive to manage our supply chain by working together with suppliers upstream and downstream to develop a circular society.
The 3Rs of waste
In addition to complying with environmental laws and regulations, we promote recycling by identifying the environmental impact of our business activities in terms of pollution and waste generation, and we are also working to reduce water withdrawals to address growing water risks.
One example of waste reduction is the installation of trash cans for resource papers, bottles, cans, PET bottles, and plastics at the head office building. General trash is separated into 12 categories that are accurately measured with scales installed at the trash disposal area for management. Since FY2018, we have managed general and industrial waste on a non-consolidated basis, and in FY2021 we expanded the management of waste emissions to a consolidated basis. As a result of our efforts to understand the recycling rate, the combined ratio of general and industrial waste was 91.0% in FY2022.

Water management
We have been identifying various water risks and taking measures in light of increasing water risks, such as water shortage and abnormal weather from climate change, and increased use of water from increasing populations and economic growth. We have established a water management system to minimize the water intake and the use of water as much as possible, while preventing the emission of contaminants.
Efforts to reduce water intake include the use of rainwater at Izumiotsu Station and Platplat, the effective use of spring water as miscellaneous water, and the use of industrial water and reprocessed water (gray water). At Namba Parks, we have installed a water purification system in the basement. It uses microorganisms and activated carbon to treat and sterilize wastewater, which is then reused for flushing toilets and sprinkling water on plantings.
The water withdrawal by our Group (consolidated) in FY2022 was 1,384 thousand m3, an increase compared to the previous fiscal year, due to the conclusion of the effects of the COVID-19 pandemic and a slight recovery trend in the economy, while the water withdrawal intensity was reduced by 3.2% compared to FY2019.
For risks of floods such as tsunamis and inundation, we have been working on continuous flyover roadway constructions and safety constructions for bridges.
Water intake

Water intake (Non-consolidated)※ | 1,116 Thousand ㎥ | 1,221 Thousand ㎥ | 1,384 Thousand ㎥ |
The amount includes not only water supply, but also industrial water of some Group companies and measurable amount of treated water and groundwater.
