Hosiden Activities
Environmental improvement of products and business activities
In Hosiden group, each company in the group sets an activity target to following environmental improvement activities and it acts. Moreover, it sets up object substances for reduction and abolition of environmental control substances by headquarters instruction.
Improvement activity cases
Activity case
Promotion of recycling
- 1. Recycling Scrap of Tape and Reel(Ps material)
Scrap of Tape and Reel (PS material) is reused as an fuel for cement production - 2. Recycling of discarded fluorescent lamps
Discarded fluorescent lamps are broken down to glasses and metals to be recycled as raw materials. - 3. Recycling of sludge
Precious metals and heavy metals are taken out from sludge generated at plating waste water treatment - to be recycled.
- 4.Activity case of other rercycling
・Promotion of reuse of abandonment tool. Especially, decomposed parts are recycled 100% in control area.
・As the result of activity aiming that all separable parts must be recycled, recycled parts have been - increased from 28 items to 31 items.
・ Recycling of dry batteries (used batteries in factories)
・Promotion of purchasing eco-products (office supplies)
Activity cases of other improvements
Hosiden group exercises its ingenuity in decreasing environmental burdens other than above mentioned.
- Activity for environmental control substances reduction
- Decrease of environmental burdens in packaging materials Reduction of packaging material made of
polyviny lchloride and abolition of binding bands made of polyvinyl chloride are carried on in the entire group.
- Setup of environmental targets related to business
- Because shortening working hours by improving productivity is related to promotion of energy conservation, and decreasing process failure by improving quality is related to waste reduction, we assume that these are environmental preservation activities.
- Execution of modal shift in a logistics section
- A modal shift that uses container train for a part of the distribution between bases began to control the amount of
CO2 generation by truck transportation in July, 2005.
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.
- Correspondence to PRTR method (the chemistry substance management promoting method)
When the usage of regulated chemical substances exceeds the legal threshold, we properly submit notifications to the relevant prefectural and municipal authorities.
- Promotion of halogen-free.
We provide appropriate support upon customer request and for products that require halogen-free specifications.
- Development of LCA (life cycle assessment)
- During the design and development phase, we investigate the presence of environmentally hazardous substances in procured materials and also assess the potential release of harmful chemicals during disposal. Through these efforts, we strive to develop products with consideration for the environment.
- The initial evaluation of the product at the design stage is executed.
- Based on our internal standard for hazardous chemical substances, "HTS A2106: Management Standard for Environmentally Regulated Substances Contained in Electrical and Electronic Equipment," we are systematically working to reduce the environmental impact of our products from the design stage. In addition, we are committed to the goal of ensuring that all our products comply with the RoHS Directive
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
Hosiden is actively working on the development of low-carbon materials and products.
●Eco-Friendly High-Speed Signal Connector
As an eco-friendly material suitable for use in high-speed signal connectors, we have customized Unitika Ltd.’s plant-derived nylon resin, "XecoT," to ensure it meets our product performance requirements. By doing so, we aim to address our customers’ environmental demands.
Activities for green procurement
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.
At this quality briefing session, we have been presenting our explanatory document titled “Initiatives to Combat Global Warming” since 2022, along with requests for cooperation from our suppliers. In 2023 and 2024, we conducted surveys to assess the status of our suppliers’ initiatives and requested data submissions from key suppliers based on transaction volume. In FY2025, we began data collection and engagement activities.In addition, at quality briefing session, we request to key suppliers to set CO2 emission reduction targets and to reduce emissions.
Through the cooperation of our suppliers in decarbonization efforts, we are working to promote the decarbonization of our manufactured products.
Education and training
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)
Monitoring activities
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.
Water surver of discharged water
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.

Measurement of noise
Each company in the group periodically measures noise comes out of the site.
Investigation of exhaust air
To prevent air pollution from boilers and scrubbers, we conduct monitoring and measurement in compliance with legal regulations.
