Reduction of Environmental Risks
A variety of environmental risk is assumed: environmental contamination caused as a result of improper management of toxic chemicals and waste, leaks/spills of hazardous substances due to aging facilities, deviations from environmental regulations in each country, etc. SII comprehensively evaluates all possible risks in advance and takes continuous prevention, protection, and reduction measures into consideration.
Regarding discharges into the aquatic environment and the atmosphere, each unit sets their own voluntary standards that are stricter than the local laws and regulations. Periodic inspections and maintenance are also carried out for environmental facilities and equipment such as drainage treatment facility, boilers, air conditioning systems, and chemical tanks.
SII researches and evaluates water risks and strives to mitigate them.
There is a wide variety of elements and scopes related to water risks, so SII first confirmed risks of water intake, risks caused by the tighter wastewater regulations, and risks related to discharging of rainwater contaminated with hazardous substances. As a result, we clarified that there is no risk that could make a significant and immediate impact in terms of operations and environmental contamination. This is due to our years of efforts in implementing measures covering assumed risks and conducting of emergency response training. We will continue our attempts to mitigate risks.
Storage and Control of PCB
SII strictly store and control equipment that has contained PCB in accordance with the related laws and regulations.
We have completed the disposal of high-voltage capacitors at all sites in FY 2015. For the remaining fluorescent ballasts and low-concentrated PCB, we will continue our thorough and appropriate storage and control while promoting early disposal.
On-site Audit at the Waste Disposer
SII entrusts waste treatment to waste disposers and carries out on-site audits on a regular basis to promote proper waste disposal. In addition to confirming the contents of the contract, we also check the acceptance and storage conditions.
The audit is accompanied by the Environment Division at the head office to see and check the waste disposers' performance. We also share the audit results among the related sites.
Environmental Risk Management
Each site has been consolidating emergency procedure manuals regarding actions and communication. Through periodic emergency response trainings based on the procedures, employees can review if the procedures are effective and then practice emergency countermeasures to prevent the spread of environmental contamination.
