Recycling-Oriented Society

KDDI promotes the 3Rs (reduce, reuse, recycle) with the aim of bringing about a recycling-oriented society. We make particular efforts to reduce the landfill waste generated by our office operations, and set aggressive materials recycling ratio targets.

Reusing and Recycling Telecommunication facilities

KDDI promotes reuse activities that employ retired telecommunication facilities effectively. We determine conversion to this equipment by taking future demand and business developments into consideration. Equipment that has been retired and can be converted is stored temporarily at our resource management center, from which it is shipped to individual sites once the next site of deployment has been determined.
We use material recycling to effectively employ equipment, components, and materials that have become unnecessary.

KDDI Paperless FAX Service

KDDI Paperless FAX Service allows our users to check the faxed content on their PC or smartphone instead of printing it on paper. This is also applicable when sending a fax; users can send their Word or Excel files from their computers via fax. Transmission records are all managed at the KDDI Paperless FAX server, so as long as there is an Internet connection available, users can view previous records anywhere, anytime.
By minimizing the amount of paper used and its storage space, we contribute to the conservation of the global environment by reducing industrial waste and the CO2 emissions generated from paper production.

Promoting Recycling of Mobile Phones

Mobile phones use gold, silver, copper, palladium, and other precious metals and rare earths. To prevent depletion of the earth's resources, we emphasize the role of recycled metal, plastic, and other resources. KDDI is an active proponent of "material recycling," which involves the reuse of recyclable materials.
At au shops, we manually disassemble used mobile phone handsets that have been collected from customers unit by unit, separating out substrates, displays, cameras, plastics, screws, iron, antennas, motors, speakers, and other items. The substrates are sent to refining companies to extract gold, silver, copper, palladium, and other resources; screws and antennas are dispatched to iron and steel manufacturers for use in steel products; and plastics are recycled into clothes hangers and other items. When a machine is used to disassemble a mobile phone, substrates and LCDs, plastics, and other components are shredded, so incineration processing is required to recover precious metals. Also, during incineration 20–30% of the plastic is burned up and so cannot be used as a recycled resource. KDDI disassembles phones manually to prevent recyclable resources from being wasted. During FY2011, our recycling ratio was nearly unity, at 99.7%.

Recycling Operation Manuals (Environment-Friendly Recycled Paper)

Throughout Japan, au shops recover for recycling the operation manuals, pamphlets and leaflets that are bundled together with mobile phones, as well as the boxes in which handsets are packaged. This effort enables us to convert items that were previously discarded as household waste into 100% "environment-friendly recycled paper." We work to create an environment resource cycle for used paper under the keywords of "recover, recycle and reuse."
KDDI uses the resulting "environment-friendly recycled paper" in envelopes for internal communications, various pamphlets and employees' business cards.
