Hosiden group exercises its ingenuity in decreasing environmental burdens other than above mentioned.
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.
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 solder
Miniature speakers with solderless connection
ECM's parts with solderless connection
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.
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.
Entire hosiden group established a reduction plan based on the corporate standard "HTS A2106" for reduction and abolishment of environmental control substances included in products.
However, it is necessary to work together with vendors because our company's products are not produced by only Hosiden group companies. Therefore, we hold a presentation meeting for vendors who supply parts and materials to obtain their understanding and cooperation.
Moreover, major vendors execute internal audit and our audit to manage environmental control substances smoothly.
Each company in the group is working on the improvement of employee's environmental consciousness through providing environmental education to each level including new employees, distributions of personal cards and pocketbooks to all employees including part-time employees and temporary employees, and reports of environmental activities by notice on the wall and company magazines.
For employees who will work on operations that possibly give a remarkable influence to environment, we provide periodical training sessions and enough education to correspond to emergency situation and require them to acquire necessary qualification.
In addition, we have established the system providing education such as presentation meeting by external examination organization and interval study session for internal environmental auditors so that appropriate internal environmental audit can be held.
We will continue to execute education and enlightenment to establish the system for environmental preservation and promote Hosiden's better environmental activities.
Environment and quality pocketbook (Headquarters)
Hosiden group's each company does not have any factor that gives big environmental impact. However, because there are chemicals that are used in production process or stored, periodical check of leakage, water quality and exhaust air is executed and training for accident or emergency situation is conducted to maintain surrounding environment.
Addition to an on-the-spot inspection by a staff of the city once every month,in-house water survey is executed based
on the in-house standard that is severer than regal provisions and is set up for daily monitoring.

In order to prevent air pollution by a boiler or a scrubber, the in-house standard that is severer than regal provisions and is
set up for monitoring and measurement.
