Environmental protection

Our environmental protection measures include efforts for the achievement of a low-carbon society, the establishment of a circular economy, and the preservation of biodiversity.

The Asahi Kasei Group is working to reduce the amount of industrial waste for final disposal through the “3-Rs” of reduction, reuse, and recycling in order to help build a recycling-oriented society.

In fiscal 2015, we adopted targets of a final disposal rate of 0.3% or less and a recycling rate of 89% or more of the total amount of industrial waste generated. We achieved our targets, with a final disposal rate of 0.2% and a recycling rate of 98%. We are working to gain further improvements through increased separation and greater selectivity in disposal contractors.

Waste containing PCBs* is stored under strict control in stainless steel vessels. Plans for disposal are advancing, including for waste with minimal amounts of PCBs.

We enhanced our management of off-site treatment of industrial waste by expanding the use of electronic manifests. We also performed periodic on-site inspections of consigned firms to ensure that proper disposal is performed in accordance with sound systems of control.

Reducing industrial waste from construction materials and housing businesses

Asahi Kasei Construction Materials recycles trimmings of Hebel™ autoclaved aerated concrete (AAC) panels in its own plants and others, utilizing its certification for “wide-area recycling”* which permits the transport of waste from different construction sites. Asahi Kasei Homes is also reducing the volume of waste as well as implementing sorted waste collection at housing construction sites. With these measures, waste for final disposal has been reduced to zero at new construction sites.
