We promote the environmental conservation activity company-wide in individual's daily work and cross-organizational team efforts.


Environmental Management System

ISO 14001 implementation

Our old Design & Manufacturing Center (D&M Center, now the Keihanna HQ) was certified under ISO 14001, an international standard for environmental management system, in March 2004. This expanded to include Tokyo office resulting in our being ISO 14001:2004 certified in March 2006.

ISO 14001 (2004) Certification:
March 2004: D&M Center
March 2006: Entire company
Registration number: JQA-EM3813

Environmental Activity

As part of our in-house environmental conservation initiatives, we have been working to reduce CO2 (electricity consumption), resource consumption (paper), and waste.

Electric power consumption rate Electric power consumption rate(Factory data only) Paper consumption volume General waste volume

* Since 2008 recycling rates have been used.

Environmental Education

To raise awareness of environmental issues among employees (including part-time and temporary staff) and promote initiatives to address them, we offer environmental education in new employee training, technical training, internal auditor training, and other general training opportunities.

Environment Friendly Manufacturing

Response to RoHS Directive

silex is working to completely abandon the chemical substances regulated by the RoHS directive, such as lead and cadmium, and other hazardous chemical substances that we have established environmental standards for. We are implementing this activity throughout all divisions related to manufacturing (Sales, Design, Procurement, Manufacturing, and Quality Assurance).
We have been delivering RoHS compliant products (also compliant to silex's original environmental standards) since June 2004, and as of January 2009, all of our products, except for certain OEM products, are compliant with the RoHS Directive.

RoHS Directive
The RoHS Directive, which came into force in the EU on July 1, 2006, restricts the use of lead, cadmium, mercury, hexavalent chromium, polybrominated biphenyl (PBB) and polybrominated diphenyl ether (PBDE) in electrical and electronic equipment.

Response to WEEE Directive

silex is working to collect/recycle products regulated under WEEE directives. We have been attaching the mark below on all the products for EU since August 13, 2006.

WEEE Directive
It is the EU directive to oblige manufacturers to collect/recycle electrical and electronic equipment used by consumers.
