RoHS*2-Compliant Products

Europe enacted the RoHS2 Directive, which restricts the use of certain hazardous substances in electrical and electronic equipment in order to prevent adverse effects on people and the environment during the recycling and disposal of such equipment. A total of 10 substances namely, cadmium, mercury, lead, hexavalent chromium, PBB (polybrominated biphenyls), PBDE (polybrominated diphenyl ethers), the 4 Phthalate ester substances namely DEHP (bis-2-ethylhexyl phthalate), BBP (benzyl butyl phthalate), DBP (dibutyl phthalate), and DIBP (diisobutyl phthalate)) have been specified as specific harmful substances. In line with this, we are working towards the total abolition of these 10 substances.
We have also established “RoHS Regulation Management Provisions” to be included in our Environmental in-house guidelines to monitor and confirm the progress towards RoHS2 compliancy.

The Management of PRTR Designated Chemical Substances

In accordance with the PRTR Act*¹, we carefully monitor the types of notifiable chemical substances that are discharged and the amount handled, and aggregate the totals each month.
In FY2022, the total volume handled by the three sites was 21.8 tons, a reduction of 29.9% from the previous year. We will continue to promote the reduction of emissions by replacing target substances and parts.
Of the target substances, the following three substances were notifiable substances under the PRTR Act and had a handling volume of 1 ton or more. We notified and reported these substances to the local government.

Substances subject to PRTR FY2022 handling amount (t)
Xylene 9.4
Toluene 6.4
Ethylbenzene 5.4

With regard to the reduction of VOC*², in FY2022, we continued to build and promote a system for proper ordering of organic paints and thinners (diversion through high repeatability bespoke paint inventory management) and proper use (reduction in the number of paint color changes, reuse of thinners for cleaning).

*¹ PRTR Act: "Act on the Assessment of Releases of Specified Chemical Substances in the Environment and the Promotion of Management Improvement". A law that requires companies to monitor and control the amount of harmful chemicals that are emitted and transferred.
*² VOC: Volatile Organic Compounds
