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 and social infrastructure systems account for approximately 90% of the total emissions of such substances, and by region, approximately 90% of such emissions originate from Japan.

Results of FY2016

In FY2016, Toshiba Group took measures for solvents used in cleaning and resin processing, which ranked high among such emissions, and promoted initiatives such as using alternative substances, starting operation of combustion detoxifying devices, and improving powder coating and other manufacturing processes in order to reduce the use of raw materials as well as reducing the amount of VOC evaporation by enhancing chemical management. As a result, the Group reduced emissions of substances targeted for reduction by 1,114 tons (44%) compared to the FY2000 level.

Future initiatives

In the Sixth Environmental Action Plan, Toshiba Group aims to reduce emissions of substances per unit activity in FY2020 to less than the FY2013 level.

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 1: Reducing environmental impact with powder coating

Toshiba Elevator and Building Systems Corporation

「粉体塗料採用による環境負荷低減」のイメージ

Toshiba Elevator and Building Systems Corporation had used xylene and toluene, which are regulated under the PRTR Law in Japan, as well as solvent coatings that contain volatile organic compounds (VOCs), including butyl acetate, which is a second-class organic solvent specified in the Ordinance on Prevention of Organic Solvent Poisoning*1. As an alternative, the company adopted a powder coating that contains none of these substances. It thus greatly reduced the environmental impact on the atmosphere caused by organic solvents (reduction of 3 tons *2 per year).

The new coating is friendly to human health and contains no formaldehyde, which is a major causal agent of sick building syndrome.

Case Study 1: Reducing environmental impact by introducing a compressor powder coating

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.
