Proper Management of Chemicals​

The jewellery manufacturing process involves a variety of specialized treatments based on scientific knowledge. TASAKI continues to engage in the proper management of chemicals to ensure that their use does not have a detrimental impact on the natural environment and to maintain a safe working environment for employees.

TASAKI promotes the following initiatives for the proper management of chemicals.

• In compliance with global standards, TASAKI does not use cadmium at all in its manufacturing processes.
• We are pursuing initiatives to reduce as much as possible the use of metals that commonly cause allergic reactions (e.g., nickel).
• We use safer chemicals in our jewellery manufacturing processes.
• We use localized exhaust systems to detoxify exhaust that contains specified hazardous substances generated during the jewellery manufacturing process.
• We neutralize and purify wastewater containing specified hazardous substances generated during the jewellery manufacturing process appropriately in a dedicated wastewater treatment facility, with channels that are kept separate from general wastewater. Only purified water is discharged as sewage, and chemicals extracted during the purification process are properly disposed of as industrial waste under the supervision of the responsible officer. Wastewater treatment facility is constantly monitored to ensure that the pH of each tank is maintained at an appropriate level, and water quality tests are conducted twice a month by a specialist contractor to ensure proper purification.
• The contents of the chemicals used in the atelier are strictly described on the label, and they are stored safely in a special chemicals cabinet to prevent the bottles from falling over.
