Reduction and Replacement of Chemical Substances of Very High Concern

(Updated on August 23, 2013)

Sony defines "Environment-related Substances to be Controlled" (hereafter "Controlled Substances") as certain chemicals that it has determined to have significant impact on both humans and the global environment, including substances that may not be controlled by laws. (Please refer to the list "'Controlled Substances' Defined by Sony.") Sony either prohibits the use of these substances in parts or phases them out wherever a viable alternative that meets all product quality and technical requirements is available. In its Green Management 2015 mid-term management targets, Sony specifies high-risk applications from collected application- and content-related information, considering the hazardous nature and extent of exposure (volume) as risk factors, and plans to prohibit the "Controlled Substances" in the specified use.

Polyvinyl Chloride (PVC)

(Updated on August 23, 2013)

PVC may pose a risk to the environment if disposed of improperly. Another concern is that PVC might contain various other chemical substances, including plasticizers and stabilizers, which could pose risks to the environment and human health.

Although PVC is not currently regulated by any laws that apply to chemical substances used in electronics products, Sony continues to promote the use of alternatives. As a result, Sony does not use PVC in product packaging materials, casings, sheets/laminates of speaker housings, contactless IC cards and carrying bags/cases for products (excluding those for professional use). Sony has also been successful in replacing PVC by a developed alternative in several internal components such as flexible flat cables, insulation plates and electrical heat shrink tubes, all of which are difficult to remove prior to recycling. Sony is concerned with the possibility that, in particular, its small electronics products could be collected for obtaining valuable materials, and then the unwanted parts could be improperly incinerated and disposed of in landfills. Considering the impact of these activities on the environment, Sony is promoting the replacement of PVC with alternative substances (for products where quality, technological and supply problems have been resolved).

As of the end of July 2013, for the following products Sony replaced PVC with alternative substances in new products and new models. In addition to information on product categories provided below, follow the link for "Examples of PVC-Free and BFR-Free Products."

Brominated Flame Retardants (BFRs)

(Updated on August 23, 2013)

  • BFR alternatives have been used in the main PWB of Xperia™ Tablet Z

Some BFRs are harmful to human health and tend to remain in the environment and accumulate in living organisms.

As is the case with PVC, improper incineration of BFRs carries a risk of releasing harmful substances into the environment. Sony replaced BFRs with alternative substances in new products and new models (for products where quality, technological and supply problems have been resolved). As of July 2013, Sony had replaced BFRs with alternative substances in all new products and new models of the products listed below. For more information, refer to the table titled "Examples of PVC-Free and BFR-Free Products."

PVC-Free and BFR-Free Product Categories*
Xperia™ smartphone
Xperia™ Tablet
Personal computer VAIO®
MP3 players WALKMAN®
Personal Navigation System nav-u™
IC recorder/Portable Radio Recorder/Linear PCM Recorder/Memory Card Recorder
Video Camera Handycam®
Digital Still Camera Cyber-shot™
Digital Photo Frame S-Frame™
Interchangeable lens digital camara α™
PSP®(PlayStation®Portable)
PlayStation®Vita
Digital Book Reader Reader™
Portable DVD Player
Portable Blu-ray Disc™/DVD Player
For example, all VAIO® personal computers currently released contain no BFRs in their casings and main printed wiring boards (PWBs).

Under the Tenth Edition of the SS-00259, which was released by Sony in 2011, Hexabromocyclododecane (HBCDD) is listed among "Environment-related Substances to be Controlled ('Controlled Substances')." Consequently, Sony plans to ban the use of HBCDD as a flame retardant used in plastics in its products, effective from 2014. This is in addition to the ban already in place on the use of polybrominated diphenylethers (PBDEs) and polybrominated biphenyls (PBBs). Furthermore, Sony plans to ban the use of tris (2-chloroethyl) phosphate (TCEP), which is a chlorinated flame retardant identified as carrying risks similar to BFRs, effective from 2014.

Sony also developed an environmentally conscious flame retardant that contains no bromine, to be used for polycarbonate plastic with high flame-retardant and thermal-resistant properties. This flame retardant is used, for example, in casings and components for interchangeable lens digital cameras, including α™58, and in internal parts of digital still cameras Cyber-shot™.

Parts in which BFRs are eliminated are as below (excluding accessories):
Xperia™ smartphones: in PWBs, casings and cables.
Products other than Xperia™ smartphones: in casings and main PWBs.


Mercury

(Updated on August 23, 2013)

  • Mercury-free alkaline button battery

Conventionally, button batteries require a minute amount of mercury to suppress the generation of hydrogen gas inside the battery. Eliminating the use of mercury in button batteries had proven very difficult from a technical standpoint. However, Sony was strongly determined to remove the environmental burden presented even by such a tiny amount of mercury. Leveraging its proprietary mercury-free alkaline button battery technologies, Sony succeeded in developing a mercury-free alkaline button battery. Sony launched sales of its mercury-free alkaline button batteries in Japan in October 2009 and commenced a worldwide rollout in August 2010. Together with the mercury-free silver oxide batteries that Sony began shipping in 2005, as of the end of 2012, Sony was shipping mercury-free batteries in over 50 countries around the world. Sony will continue to promote further reductions in the volume of mercury it uses.

Phthalates

(Updated on August 23, 2013)

Sony is working to eliminate specific phthalates (phthalic esters), which are used as plasticizers in PVC, among other substances. Among these specific phthalates, for example, Sony has succeeded in eliminating phthalates (DEHP, DBP, BBP, DIDP, DNOP and DINP)*1 from Xperia™ smartphones. Sony has also eliminated the use of phthalates in the bodies of PSP® (PlayStation®Portable) units and in the AC adapters packaged with those units shipped to Europe.

*
DEHP: Bis(2-ethylhexyl) phthalate, Di(2-ethylhexyl) phthalate; DBP: Dibutyl phthalate, Di-n-butyl phthalate; BBP: Benzyl butyl phthalate, Butyl benzyl phthalate; DIDP: Di-isodecyl phthalate; DNOP: Di-n-octyl phthalate; DINP: Di-isononyl phthalate.


Beryllium Compounds

(Updated on August 23, 2013)

Sony has designated beryllium oxide and beryllium copper as "Controlled Substances" since 2007 and is working to eliminate these substances. No beryllium oxide is used in any of its products. Sony has also succeeded in eliminating beryllium compounds from Xperia™ smartphones.

Arsenic Compounds

(Updated on August 23, 2013)

Under the Tenth Edition of the SS-00259, which was released by Sony in 2011, diarsenic trioxide and diarsenic pentaoxide are listed among "Environment-related Substances to be Controlled ('Controlled Substances')." Consequently, Sony plans to ban the use of these two compounds as antifoam agents for LCD panels, effective from 2014.
