Management of Chemicals in Products

In addition to ensuring proper management of chemicals contained in products, Toshiba Group also promotes communication and information sharing on such chemicals through the value chain to minimize risks to human health and the global environment.

Toshiba Group’s initiatives for the management of chemicals contained in our products

Toshiba Group manufactures and sells a wide range of products, from electronic devices (e.g., semiconductors and hard disks) to audio-visual products (e.g., PCs and TVs), building- and facility-related devices (e.g., air conditioners, elevators, and lighting devices), industrial systems (e.g., motors and railroad systems), and energy and social infrastructure products (e.g., power generation, transmission, and distribution systems). Various chemicals are used to manufacture these products. To properly manage these chemicals and to achieve our goal of minimizing the risks involved in the use of chemicals in accordance with the precautionary principles, which were proposed and adopted at the World Summit on Sustainable Development (WSSD*1) and other conferences, Toshiba Group has been promoting initiatives to specify the chemicals to be managed, to eliminate the use of specified chemicals (including the use of substitute materials), and to reduce the amount of chemicals contained in our products. In addition, we also promote communication and information sharing on such chemicals through the value chain in order to minimize risks to human health and the global environment throughout product lifecycles.

Also, to respond to the globalization of business, Toshiba Group is developing global measures to manage chemicals contained in products. To this end, we are collaborating with regional environmental divisions (in China, Southeast Asia, Europe, and the U.S.) to gather and assess the impact of policies and regulations of countries around the world to enhance Toshiba Group's management of chemicals.

Furthermore, to promote the Green Procurement initiative, Toshiba Group has specified "prohibited substances," whose presence is prohibited in procurement items, including product materials and parts, and "managed substances," whose environmental impact should be reduced, based on their actual usage, via reduction of use and substitution. Our aim is to procure products, parts, and materials in cooperation with our business partners and suppliers to minimize the environmental impact of these chemicals.

Toshiba Group Environment-related Substance List
Category Definition
Rank A
(Prohibited Substances)

Promoting use of alternatives to PVC/BFRs

Results of FY2015 and future initiatives

In the Fifth Environmental Action Plan, Toshiba Group set a goal of using substitute materials to replace polyvinyl chloride (PVC) and brominated flame retardants (BFRs) contained in products across a total of 80 product groups. In FY2015, we reduced the use of PVC and BFRs in lifestyle products and social infrastructure products as well as expanded the scope of our initiative from 54 product groups, for which we achieved our goal in FY2014, to 76 product groups. We will continue our efforts this fiscal year to promote the use of alternatives to PVC/BFRs.

*
As a result of changes to Toshiba Group's business structure, we excluded medical equipment and home appliances from the target product groups. Consequently, the total number of product groups targeted for our initiative in FY2016 has changed from 80 to 66.

The following are examples of products for which Toshiba Group promoted the use of alternatives to PVC/BFRs in FY2015.

Case Study 1: POS system

[Image] POS system

Toshiba TEC Corporation

POS systems make use of cable harnesses with assembled parts made from multiple electric wires (for power supply and signal communication) that have been bound together.

Toshiba TEC Corporation had been using PVC harnesses that were soft and provided a large degree of freedom in wiring. However, the company considered adopting PVC-free harnesses and is now using parts that do not contain PVC. Toshiba TEC will use this case study as an example to promote the use of PVC alternatives in other products.

Case Study 2: Elevator

Toshiba Elevator and Building Systems Corporation

In manufacturing elevators, resin-coated decorative copper plates as well as lighting covers and tiles made of PVC were previously used to provide color variations and finishing touches to the interiors of elevator cages as well as to increase elevator durability. Toshiba Elevator and Building Systems Corporation evaluated the possibility of using PVC-free materials in such parts and adopted these materials to produce PVC-free elevators.

Case Study 3: Ventilator instruction label

Toshiba Carrier Corporation

PVC had been used for many years to manufacture instruction labels for products (e.g., ventilation fans) that must be cleaned by customers with detergent. This is because PVC is known to protect printed letters from being washed off by detergent as well as to make it easy to use an adhesive that prevents labels from easily peeling off.

To find an alternative to PVC for instruction labels, the company tested different combinations of mounts, adhesives, and printing ink to examine detergent resistance and the difficulty of peeling off, eventually succeeding in commercializing a PVC-free label.

Initiatives for communication of information on chemicals throughout the supply chain

REACH*4, the European regulations on chemicals that came into force in June 2007, mandates development of a system for effectively disclosing and communicating information on chemicals contained in parts, materials, and products throughout the supply chain. Toshiba Group has actively adopted the JAMP*5/AIS*6 format, the industry's standard survey format, to promote effective communication of information on chemicals contained in products throughout the supply chain.

To promote business activities aimed at reducing the environmental impacts of hazardous chemicals and the risks involved in using them, it is essential to obtain the cooperation of suppliers, our business partners, for those activities for which the supply chain as a whole must be targeted. We request the understanding and cooperation of our suppliers in our green procurement initiatives aimed at creating a sustainable society. We also request that they make environmental assessments and conduct research on and evaluations of the chemicals contained in the materials and parts they supply and report the results of independent assessments on their level of green procurement (according to Toshiba's standards) in accordance with ISO 14001.
