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 amount of released chemical substances, which are classified into "reduction substances" into the atmosphere and water that directly affect the environment. We will continue to reduce amount of released chemical substances by introducing manufacturing equipment with low released chemical substances and reviewing the processes.

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.
