Reducing Emissions of Chemical Substances

Toshiba Group strives to reduce the consumption of chemical substances by designating substances that have large direct impacts on the environment as those targeted for reduction. By business segment, electronic devices, power and social infrastructure systems, and community solutions account for over 90% of the total emissions of such substances, and by region, 80% of such emissions originate from Japan.

Results of FY2015

In FY2015, Toshiba Group gave priority to taking measures for solvents used in cleaning and resin processing, which ranked high among such emissions, and promoted such initiatives as using alternative substances, starting operation of combustion detoxifying devices, improving manufacturing processes in order to reduce the use of raw materials, and reducing the amount of VOC evaporation by enhancing chemical management. As a result, the Group reduced emissions of substances targeted for reduction by 1,074 tons (43%) compared to the FY2000 level.

Future initiatives

In the Fifth Environmental Action Plan, the Group aims to reduce the emissions of substances in FY2016 to 1,660 tons. It plans to use alternative substances and increase material efficiency by improving processes as an incoming countermeasure and expand introduction of emission removal and collection equipment as an outgoing countermeasure.

Case Study: Reducing environmental impact by introducing a compressor powder coating

Powder coating by robots

Toshiba Carrier Corporation Fuji Factory & Engineering Center

At Toshiba Carrier Corporation's Fuji Factory & Engineering Center, workers previously coated compressors by soaking them in watersoluble paint having a 35% composition of volatile organic compounds (VOCs). Recently, the company newly adopted a powdercoating system that makes use of robots to apply powder coating paint containing no VOCs, thereby reducing VOC emissions by 6.4 tons per year. As a result, the plant now recycles more than 95% of the paint used in powder coating, thereby reducing waste paint by 720 kg* annually.
