Kao is developing an operating system and initiatives to limit the effects of waste and a wide range of other environmental impacts.

2015 activities

We have conducted ongoing activities to reduce the volume of waste and other unwanted materials we generate, but higher production volumes resulted in an increase in the amount of waste and other unwanted materials generated in 2015. The Kao Group in Japan has achieved its zero-emission targets for the 11th consecutive year.
Kao also regularly conducts on-site checks of waste disposal providers directly contracted to dispose of waste, and conducted on-site checks at 152 facilities in 2015.

Promoting initiatives to reduce waste

Among its 3R initiatives toward creating a recycling-based society, Kao is promoting reduce, reuse and recycling of waste generated inside and outside the company.

At production sites, efforts to reduce the amount of waste and other unwanted materials generated include altering production methods so as to reduce the volume of product loss and offcuts generated, and adjusting equipment washing procedures to reduce wastewater. We are continuing to reduce and reuse distribution materials at logistics centers, and at offices, continuing to manage the quantity of paper used.
Although we have implemented these measures, the amount of waste and other unwanted materials generated in 2015 increased by 9,000 tons year on year due to higher production volumes and expanding production lines. The amount of waste generated per unit of sales remained at 27% relative to 2005 levels, the same as the previous year. This falls below the target of 30% for all Kao Group production and non-production worksites. We will further strengthen efforts to promote waste reduction activities in 2016.
Of the amount of waste generated, 15,000 tons was hazardous waste. No hazardous water was transported internationally under the Basel Convention.
Waste that was reused or recycled came to 197,000 tons, with a recycling rate of 90%.
We maintained our target of 0.1% or lower final disposal ratio for waste. We have achieved our target of zero emissions for the 11th consecutive year since the target was set (all Kao Group worksites in Japan, final disposal ratio of waste generated).

Strengthening waste- and recycling-related governance

At Kao, efforts are being promoted to reduce the risk of illegal dumping, etc. with regards to disposal of waste by our business activities. This goes beyond managing information about the amount of waste generated, recycled or ultimately disposed of; to ensure that waste is properly disposed of when the disposal is contracted out to other firms, Kao implements regular inspections of facilities of the waste disposal providers directly commissioned by Kao.

In 2015, Kao carried out on-site inspections of 152 facilities belonging to 131 firms with which Kao collaborates.
In Japan, Kao has developed the Waste Recycling Governance System for coordinated management of contract data and control manifests for waste, as well as other quantitative data and the results obtained in surveys of appropriate waste management. This system is also connected to the Electronic Manifest System. Kao is working to continue expanding its use of this system within the Kao Group in line with efforts to expand the use of electronic manifests being promoted by the government.

Proper storage and treatment of PCB

Waste containing polychlorinated biphenyl (PCB) in insulating oil, such as in transformers and ballasts, is stored at Wakayama Plant, Sumida Office, Kawasaki Plant, Kashima Plant, Odawara Office, and Kao Sanitary Products Ehime under the regulations until treatment and disposal are contracted to a waste disposal provider.

In 2015, we did not treat waste containing high levels of PCB. Five waste items containing PCBs were treated and disposed of.

Initiatives to prevent air pollution

To prevent air pollution, we work to maintain our equipment and facilities, and Kao monitors pollutant levels in exhaust gases in accordance with the law and with local government agreements. All plants with the necessary infrastructure use natural gas to limit emissions of SOx, a substance known to cause acid rain.
Emission of NOx decreased by 82 tons in 2015 compared with the previous year, an 8 percentage-point improvement on a per unit of sales reduction rate basis.
Emission of SOx decreased by 7 tons in 2015 compared with the previous year, a 3 percentage-point improvement on a per unit of sales reduction rate basis.

Initiatives to prevent water pollution

Kao operates and maintains wastewater treatment facilities at a high level at most plants. After properly treating the wastewater, it is discharged outside the plant. The quality of the discharged water is monitored for pollutants based on laws and regulations as well as agreements with nearby local governments.

The discharged volume of COD increased by 50 tons in 2015 compared with the previous year and deteriorated 5 percentage points on a per unit of sales reduction rate basis.

Surveys of groundwater and soil contamination

In light of its history of use of chemical substances, Kao voluntarily measures the levels of substances regulated by standards within the premises of each plant every year.

In 2015, investigations were conducted at Wakayama Plant, Sakata Plant, Tochigi Plant and Odawara Office, and it was confirmed that levels of all substances were below their regulatory limit values across all test items.
Additionally, at Wakayama Plant and Kawasaki Plant, we also conducted an investigation of any soil contamination attributable to our business activities, in accordance with laws, etc., and it was confirmed that levels of all substances checked were below their regulatory limit values.

Global

Compliance with environmental laws and regulations

Kao operates and maintains facilities and work procedures at a high level to ensure compliance with various environmental laws and regulations, whose standards grow increasingly strict each year.
While not a major leak, wastewater at a level slightly exceeding regulations was discharged at Kao USA in 2015 due to improper work procedures.
