Environmentally Conscious Production

ISO 14001 Certification Initiatives

1998 Japan factory

OKI DATA’s Fukushima Division, our production site in Japan, acquired ISO 14001 certification on 25 March 1998. Based on an environmental management programme, we promote activities for pollution prevention, energy savings, resource conservation, and reduction of industrial waste.

1998 Thai Factory

OKI Data Manufacturing (Thailand) manufactures LED print heads for OKI DATA’s page printer products and conducts integrated production for page printers, faxes and dot matrix printers. It obtained ISO 14001 certification on 28 July 1998, and as of December 2006, both sites are covered under the OKI Group’s comprehensive ISO 14001 certification.

2003 China Factory

In light of the growing Chinese market, we established the Shenzhen facility in 2002 to serve alongside our Thailand plant as a major production site. The facility has been steadily commencing production of page printers, primarily dot matrix printers.

Pollution Prevention and Environmental Protection

CFC-115 used in temperature-controlled rooms at production facilities has been replaced by an alternative coolant as of September 1998, and use of halon-1301 in fire extinguishers has been eliminated as of 1999.

We work to rigorously ensure that hazardous substances are not used in production, starting with the substances identified by the RoHS directive.

Use of lead solder eliminated

For the substrate assembly process at the Fukushima facility, we began using lead-free solder in 2006, and have reduced use of solder containing lead to zero as of 2015. Moreover, in terms of the quantity of lead-free solder used as, we are reducing solder scrap through the use of alternative materials, improvement of equipment and other measures.

Green purchasing and green procurement

We actively purchase office supplies with the Eco Mark, and with cooperation of suppliers, we promote green procurement that incorporates chemical substances management.

Paper use reduction and recycling

We have worked to reduce the quantity of paper used in printer performance testing and other processes by improving test confirmation methods. In administrative divisions, we promote activities to reduce paper use, including duplex printing and use of backing paper. Additionally, paper is sorted for recycling collection, from high-quality paper, newsprint, magazine paper, confidential documents, cardboard and other categories.

Management and Analysis of Chemical Substances in Products Chemical substance information management system

RoHS and other chemical substance data are obtained from suppliers and registered for management in the chemical substance information system “COSMOS” in accordance with the OKI Data Green Procurement Standard.
We’ve also developed the Global RoHS Navi System that connects all global production facilities and sales companies. Information on chemical substances contained specifically in products provided to facilities in each region is registered, and the system is operated so that management information can be confirmed by sales divisions.

Chemical substance analysis system

Analysis equipment has been installed at each production facility so that components can be quickly analysed for chemical substances, and we also work to continually enhance the list of substances that are measured.

Waste Elimination Measures and Recycling

Having begun with measures for industrial waste in 1997, the Fukushima Division works to reduce, recycle and reuse its waste products. Thanks to facility-wide reduction and recycling initiatives and to rigorous sorting and collection, the division achieved the recycling rate of 99.94% (2.05 tons), and has continued to maintain zero-emissions status (recycling rate of 99% of more) within the OKI Group since fiscal 2001.

Resource Conservation Measures

We work to promote the 3Rs for resource conservation as well and particularly focusing on material recycling, for example
  • Cardboard reused to manufacture cushioning materials
  • Plastics converted to reclaimed materials through volume reductions
  • Cushioning materials reused through rigorous sorting
  • Wooden delivery pallets reused

Thai Factory

Donation of Notebooks Using Backing Paper

Notebooks using test-printed backing paper are donated to schools and public institutions in Thailand. We have also opened a recycling shop for the conversion and reuse of wooden pallets.

Construction of Recycling-based Wastewater Treatment System

A recycling-based wastewater treatment system has been constructed at OKI Data Manufacturing (Thailand) to process wastewater generated at the site. Previously, the 12,000 tons of wastewater given off each month was treated with a membrane treatment system onsite up to appropriate water quality levels and then sent to a wastewater treatment facility within the industrial park. The water quality has been increased to a level that allows the water to be reused on site. The system processes 12,000 tons of wastewater monthly, and 2,000 tons of treated water is reused at the facility, which is expected to reduce costs by ¥1.70 million annually.
