Environmental Protection Planning and Results Activities for environment-conscious products

Measures for enviromental protection material

Assuming that reduction and abolition of the environmental control substances in products and in the production process is an important problem for environmental preservation, we have continued activities shown below. We will keep producing environmental-friendly products from the design stage in the future based on the reduction plan of environmental control substances that our company set up.

Content of measures

  • Abolition of RoHS directive object substances (lead, cadmium, hexavalent chromium, mercury, PBB and PBDE) in the products.
    We have already abolished mercury, PBB and PBDE in our products.Moreover, lead-free, cadmium-free and hexavalent chromium-free have been promoted since 2003. Especially, development and sales of solderless connection products has been conducted to reduce the soldering process by a customer as an approach of lead-free.
  • Example of mounted PC board lead-free solderExample of mounted PC board lead-free solder
  • Miniature speakers with solderless connectionMiniature speakers with solderless connection
  • ECM's parts with solderless connectionECM's parts with solderless connection
  • Correspondence to PRTR method (the chemistry substance management promoting method)
  • Promotion of halogen-free.
  • Halogen-free componentsHalogen-free components
  • Development of LCA (life cycle assessment)
    Decrease of load given to global environment at the life cycle of products and development of environmental harmony type products.
  • The initial evaluation of the product at the design stage is executed.
    "Regulation of the use of certain hazardous substances in electrical and electronic equipment - A2106", criteria of control for the hazardous chemicals used for parts and devices that compose products of Hosiden group was established for measures of environmental control substances in July 2002, and decrease of environmental burdens has been advanced in Hosiden products from the design stage in accordance with the plan.

Moreover, we are working to achieve the goal that all products comply RoHS directive.

XRF measurement (Wavelength-dispersiveX-Ray fluorescence measurement) device was introduced to investigate the content of environmental control substances in the products.In addition, GC-MS(Gas Chromatograph Mass Spectrometer) is also in use to analyze contents ratio of Phthalate esters, Brominated Flame Retardants (PBB, PBDE).The measurement devices were installed in the main production sites, so that componential analysis of the content substances can be conducted at each site.

Development of enviromental products

The development of the products for the environment such as for the photovoltaic generation equipment is evolving more and more in parallel with correspondence to environmental control substances.
