Environmentally Conscious Global Production

ISO 14001 Certification Initiatives

1998 Japan factory

OKI DATA’s Fukushima Division, our production site in Japan, acquired ISO 14001 certification on March 25, 1998. Based on an environmental management program, 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 mainstay page printer products and conducts integrated production for page printers, faxes and dot impact printers. It obtained ISO 14001 certification on July 28, 1998, and as of December 2006, both sites are covered under the OKI Group’s comprehensive ISO 14001 certification.

1998 UK Factory

Our UK facility is OKI DATA’s European production site, and it has established a production system that meets the strict environmental protection standards of European countries and gives adequate consideration to the environment. It also participates in a forest revitalization project as a part of its environmental protection program and has planted some 1,500 saplings.

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 impact printers.

Carbon Zero Facilities

Carbon Zero Emissions Facilities Initiative

OKI DATA, from the second half of fiscal 2009 to the end of fiscal 2012, conducted the Carbon Zero Emissions Facilities Initiative to reduce overall CO2 emissions at all facilities that produce printers and multifunction printers by implementing reduction measures and utilizing carbon offsets for remaining emissions.

The initiative included the Fukushima Division, OKI Data Manufacturing (Thailand), and the printer section of OKI Electric Industry (Shenzhen) in China. OKI DATA conducted carbon offsetting for the three facilities by purchasing and cancelling emissions credits equivalent to CO2 emissions given off the previous fiscal year every half-year from the second half of fiscal 2009 to the end of fiscal 2012.

We promoted the initiatives by including the “Manufactured at a Carbon Zero Facility” logo on products, catalogs and other materials produced by the three facilities to broaden understanding of carbon offsetting and to serve as a model company to spur other carbon offsetting initiatives, independent reduction efforts by citizens, companies and other institutions, and concrete measures to address global warming.

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 well, we are reducing solder scrap through selection of 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. Also, we sort paper into high-quality paper, newsprint, magazine paper, confidential documents, cardboard and other categories for collection, and recycle it into toilet paper and other products.

Management of Chemical Substances in Products

Chemical substance information management system:

RoHS and other chemical substance data is 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 analyzed for chemical substances, and we also work to continually enhance the list of substances that are measured.

Saving Energy

In fiscal 2006 we reduced energy consumption by approximately 1,169 thousand kilowatts, or 23%, compared to fiscal 1996 through energy-saving measures for lights and office equipment, improving production facilities and developing more efficient work processes.

such sources, we reduced the amount, on a crude oil equivalent basis, in fiscal 2066 by 109 kiloliters, or 33%, compared to fiscal 1996. We intend to continue working to further reduce power and energy consumption.

Waste 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) in fiscal 2006, 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 focus on material recycling. Here are some examples:
  • 1. Cardboard reused to manufacture cushioning materials
  • 2. Plastics converted to reclaimed materials through volume reductions
  • 3. Cushioning materials reused through rigorous sorting
  • 4. 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, and conduct other unique activities.

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, but employees increased in number and use of cooking oil at the cafeteria, for example, increased, so it became necessary for the facility to reinforce its onsite membrane treatment system. It therefore installed wastewater treatment equipment with six times the processing capacity of the previous system, and succeeded in raising the water quality to a level that allows the water to be reused at the site. We were able to create a recycling-based wastewater treatment system that does not require the industrial park’s wastewater treatment facility and allows water to be reused onsite. 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.
