Initiatives for Resource Recycling

Astellas recognizes that since the use of sustainable resources is essential for continuing its business activities, it must play an active role in the creation of a recycling-oriented society. We have established an Environmental Action Plan and are moving forward with steps to effectively use water resources and recycle waste materials (reuse, recycling, and use of all thermal energy) as initiatives contributing to a recycling-oriented society.

Effective Use of Water Resources

Environmental Action Plan (Measures for the Conservation of Resources)

Improve water resource productivity by around 20% of the fiscal 2016 result by the end of fiscal 2025.
  Applicable areas: Research and production sites in Japan and overseas 
  Indicator: Revenue (billions of yen) /Volume of water resource withdrawn (1,000 m3)


Effective Use of Water Resource

The effective use of water resources serves as a useful indicator for gauging society’s impact on biodiversity. Astellas assesses the relationship between water resources and economic activity using a water resource productivity index, and has been striving to improve this index. Water resource productivity for fiscal 2022 improved significantly by 48% compared with the base year of fiscal 2016.

Recycling of Water and Reducing Water Consumption

Astellas’ operations use only water drawn from surface water and groundwater. Water used in work operations is treated in accordance with wastewater discharging standards and returned to an aquatic environment. In addition, Astellas is continuously working to reduce water consumption while minimizing process wastewater. The amount of water recycled is almost equivalent to the entire amount of water intake.

Risk Assessments

Water is indispensable for Astellas’ research and production activities. Each business site obtains necessary government approval to use water, and wastewater is discharged after being treated to satisfy wastewater discharging standards. In fiscal 2022, there were no cases of non-compliance with regulations at each business site.
Moreover, Astellas uses Aqueduct provided by World Resources Institute to analyze water risks specific to the operating regions where its plants and other facilities are located.
The Astellas Group on a global basis does not currently withdraw water from water bodies in areas concerned with water resource depletion. As water risks may emerge in the future as a result of climate change, we are conducting risk analysis and taking steps to minimize our dependence on such resources, and also regard this as an effective means of ensuring business continuity.

Waste Management

Environmental Action Plan (Waste Management)

Improve waste generated per unit of revenue by around 10% of fiscal 2016 result by the end of fiscal 2025.
  Applicable areas: Research and production sites in Japan and overseas
  Indicator: Volume of waste generated (tons)/Revenue (billions of yen)


Waste Management 

Astellas is promoting efforts to reduce the waste landfill volume to as close to zero as possible through the proactive recycling and reuse of waste materials. Moreover, Astellas also evaluates the relationship between the waste generation volume and economic activities with the index known as the Waste generated per unit, and the Company is making efforts to improve it.
In fiscal 2022, the waste generated per unit improved 16% over the base year (fiscal 2016).

Waste Management in the Value Chain

In waste management, it is also important to prevent environmental pollution being caused by hazardous waste generated by research centers and manufacturing plants and the illegal disposal of that waste. As a means of prevention, we first examine appropriate methods of waste disposal, and then conduct regular on-site assessment that waste treatment contractors are using appropriate waste treatment methods.

State of High-Concentrate PCB-contaminated Waste Storage

We have been systematically conducting detoxification of any high-concentrate PCB-contaminated equipment that is stored by Astellas. Load-figure registrations for all items stored at each of our business facilities have been completed, and the waste storage situation at the end of March 2023 was as follows. We plan to treat the entire amount by the end of fiscal 2023.
