Management of Chemicals for Products

The Toshiba Group is committed to the total eradication of the chemical substances specified below, as well as to decreasing other substances in products and to managing content levels, regardless of lack of full scientific certainty, in accordance with the precautionary principles adopted in WSSDNote and so on. This is aimed at ensuring the safety of our products and preventing release of environmentally harmful substances.

Working to Abolish the Use of Specified Chemicals

Long before July 2006 when the RoHSNote (Restriction of the use of certain Hazardous Substances in electrical and electronic equipment) Directive of the European Union (EU) banned the use of six substances for any products sold within the EU, Toshiba Group had achieved complete compliance with chemical substance control regulations for products in each country, by ceasing the use of the six substances specified by the RoHS Directive in all products introduced from April 2005 onward.

Under the Fourth Voluntary Environmental Plan, which started in FY2005, Toshiba Group identified 15 rank A chemical substances and set the goal of eliminating all of these substances from its products by FY2010. In FY2008, the fourth year of the Plan, the ratio of products that did not contain any of the 15 chemical substances of all products sold reached 89%. We are steadily carrying out activities to eliminate all these substances from our products.

Note)
RoHS (Restriction of the use of certain Hazardous Substances in electrical and electronic equipment) Directive: It is a directive banning the use of specified hazardous substances for electrical and electronic equipment. This applies to the following six substances: lead, mercury, cadmium, hexavalent chrome, and the bromine series flame retardants (PBB [polybrominated biphenyl] and PBDE [polybrominated diphenyl ether]).

Efforts to Reduce and Manage Chemical Substance Content Rates

In Toshiba Group, the prohibition of use, reduction in content rate and management of content rate of the chemicals in products are classified into specific ranks, to ensure the substances can be properly managed. The Group’s “Regulations to implement green procurement” which were totally revised in November 2006, have defined 34 substance groups (rank A), the use of which is prohibited in any products and 20 substance groups (rank B), which the Group should try to reduce and replace with alternatives.

We will use alternatives for all our consumer electronic products, if they are available from the viewpoint of mass production and cost efficiency and also if they can reduce the environmental burden without affecting the capabilities, performance, or quality of products, to replace PVC and BFRs in class B Group by FY 2009 and Phthalates, Beryllium and Beryllium Compounds as well as Antimony and Antimony Compounds by CY 2012.

Note)
Rank-B substance groups: polyvinyl chloride, antimony/antimony compounds, arsenic/arsenic compounds,beryllium/beryllium compounds, bismuth/bismuth compounds, brominated flame retardants (excluding PBBs and PBDEs), nickel (for external use only), certain phthalates, selenium/selenium compounds, zinc compounds, chlorinated paraffin (excluding some short-chain chlorinated paraffins), trivalent chrome/trivalent chrome compounds, cyanogen compounds, nickel (excluding external use)/nickel compounds, perfluorocarbons, hydrofluorocarbons, halogen resin additives (excluding bromic flame retardants), sulfur hexafluoride, manganese compounds, organotin compounds (excluding TBT and TPT)

Green Procurement Initiatives

Toshiba Group has established the Green Procurement Guidelines, in accordance with the Regulations to Implement Green Procurement, while it has also been championing green procurement worldwide in cooperation with its suppliers. Prior to the procurement of parts and raw materials, the ratios of environmentally harmful substances and scarce resources relative to the weight of procurement items have been checked, Toshiba prioritizes the use of parts and raw materials which are superior in terms of environmental impacts. We make it a rule to compile such information into a database and utilize the same for developing ECPs.

Addressing New Regulations

In an effort to meet the European regulations on chemical products known as REACH*1, which were enforced in June 2007, it is necessary to establish a system for disclosing and conveying information on chemical substances contained in parts, materials, and products smoothly within a supply chain. Toshiba Group is also establishing a system and its corresponding infrastructure for managing the giving and receiving of information on such chemical substances. In order to ensure the appropriate giving and receiving of information in a supply chain, we will also actively make the most of tools, information infrastructures, and other systems offered by JAMP*2 of which we are member.

REACH: Registration, evaluation, authorization, and restriction of chemicals
*2
