Management of Chemical Substances

We classify chemical substances applicable to the environmental laws and regulations into three types: "prohibition", "reduction" and "control".

Minimizing emissions of chemical substances used in the manufacturing process

We strive to reduce emissions of chemical substances, which are classified into "reduction", into the atmosphere and water that directly affect the environment. In fiscal 2017, TOSEI that had used paint left Toshiba Tec Group, resulting in a significant reduction of emissions. We will continue to reduce emissions by introducing manufacturing equipment with low emissions of chemical substances and reviewing the process.

Approach by Each Site

Cleaning solvent substitution

P.T. TEC Indonesia

Isopropyl alcohol is used to clean manufacturing systems and equipment in the manufacturing process. We have been using alternative cleaning solvents with lower environmental impact at four group companies including P.T. TEC Indonesia.

Training for professionals responsible for handling chemical substances

Toshiba Tec Information Systems (Shenzhen) Co., Ltd.

We provide group training on the management of chemical substances as well as practical training on their proper management and usage in the manufacturing process for managers who deal with chemical substances, and operators who are responsible for handling them and who are in charge of safety.

Reduction of volatile organic compounds (VOC)

Management of Chemical Substances

Shizuoka Business Center (Ohito)

Training was provided on the management of chemical substanc-es. Specific topics included the re-quirements of applicable laws and regulations, actions we take, how to manage facilities, and management that factors in potential risks.

Reduction of volatile organic compounds (VOC)

Toshiba Tec Information Systems (Shenzhen) Co., Ltd.

As a result of changing cleaning material for jigs used to produce electronic circuit boards, from isopropyl alcohol to electrolyzed water, we have reduced usage and emissions of chemical substances.

Multi-spot flow

Toshiba Tec Information Systems (Shenzhen) Co., Ltd., Toshiba Tec Malaysia Manufacturing Sdn. Bhd., P.T. Tec Indonesia

We introduced the multi-spot flow equipment. It reduced chemical substances used in the pre-soldering process by applying them only to necessary areas instead of the entire area.

Reduction of the amount of purchase/waste with IPA* recovery regeneration system

Toshiba Tec Singapore Pte Ltd, P.T. Tec Indonesia

recovery regeneration system

Since fiscal 2009, we at Toshiba Tec Singapore Pte Ltd, P.T. Tec Indonesia have adopted solvent recycling machines to reduce input/emissions through recovery and regeneration of IPA. This system is used to separate the residual waste and restore IPA to its original condition as a solvent. As a result, 95% of IPA can be successfully recycled and reused.

  • *IPA: Isopropyl alcohol

Reduction of IPA through updated soldering equipment

P.T. Tec Indonesia

We are reducing the use and emissions of chemicals through the systematic renewal and introduction of equipment. We were able to cut IPA use by 25% during substrate manufacturing in fiscal 2019 by updating our soldering equipment.

Additional introduction of VOC emission improvement equipment

Toshiba Tec Information Systems (Shenzhen) Co., Ltd.

We installed three VOC* emission control devices and successfully reduced the emissions by approx. 80%.
