Chemical Substances Control
Chemical Substances Control
Substances covered by the environment-related laws and regulations are classified into three types: 'prohibition of use,' 'reduction in use' and 'control of release.' In terms of 'reduction in use,' the TOSHIBA TEC Group strives to reduce the release of chemical substances, which have a direct impact on the environment. In fiscal 2010, the amount of chemical substances was reduced by 5% in Japan, compared with the previous year. It was reduced by 9% outside Japan despite the expanding scale of production, compared with the previous year.
The TOSHIBA TEC Group makes efforts to reduce the purchase, waste and emissions of substances with solvent waste recycling machines and power coating without solvent.

Reduction of the Amount of Purchase/Waste with IPA* Recovery Regeneration System
TOSHIBA TEC SINGAPORE ELECTRONICS PTE LTD, P.T. TEC INDONESIA
Since fiscal 2009, TOSHIBA TEC Singapore Electronics Pte Ltd. and P.T. TEC Indonesia have adopted solvent waste recycling machines to reduce input emissions through IPA recovery regeneration.
This system is used to separate and restore the residual waste IPA to its original condition as a solvent. 95% of IPA can be successfully recycled and reused.
* IPA: Isopropyl alcohol
Powder Coating without Solvent
TOSEI ELECTRIC CORPORATION
A part of solvent coating was replaced with powder coating, in order to improve the coating quality of the panels of washing machines and reduce organic solvents. Accordingly, the coating booth was designed for solvent and powder coatings, and the drying furnace was renewed. As a result, the usage of organic solvents was reduced by 7%, compared to the usual method. A scratch-resistant coating was achieved by increased coating thickness.
