In order to continuously provide the latest services of our telecommunications business in a stable manner, equipment must be appropriately updated and integrated. When communications equipment becomes obsolete, recycling is the first option. However, should this prove unfeasible, we accurately take account of quantity of equipment before processing it in the best way possible.

Throughout fiscal 2005, we continued efforts to reuse obsolete equipment in-house, and this resulted in the reuse of 576 items. As a result, we were able to maintain the related recycling rate at a level roughly on par with the previous year despite a decline in the total waste volume.

*Recycling rate =	Valuable weight + recycled weight
	Total waste volume

As part of efforts to provide customers with services based on the latest communications technology, NTT Communications frequently upgrades or tears down facilities. In fiscal 2005, the recycling rate for designated materials declined to 93.6%, while for other materials (except for sludge), the recycling rate was 71.2%. In fiscal 2006, we will continuously undertake measures to improve recycling rates through realizing our target of"zero disposal"of waste at final disposal facilities and promoting consignment of recycling to contractors with high recycling rates.

NTT Communications is making sustained efforts to reduce the volume of paper used in the course of administration and in the brochures and flyers we distribute to customers. At the same time, we are aiming to conserve virgin pulp through promoting a shift from using high quality paper to recycled paper.

The promotion in fiscal 2005 for further switching to recycled paper resulted in the percentage of virgin pulp used roughly on par with the previous year, although the total volume of paper consumption increased.

Looking to the future, we plan to further promote a shift to using 100% recycled paper and make efforts to significantly reduce the use of virgin pulp.

Under its Medium- and Long-Term Plan, NTT Communications is aiming to achieve an office waste-recycling rate of 70%, and working to ensure that such waste is processed, managed, and collected and sorted appropriately in accordance with the relevant legislation.

Accordingly, we were able to improve the recycling rate in fiscal 2005 as a result of the thorough sorting process.

Fiscal year	Total waste volume	Valuable weight	Recycled weight	Final disposal volume	Recycling rate
2005	4,134	2,128	2,004	941	51.5%
2004	6,553	3,152	3,401	626	48.1%

NTT Communications established guidelines for managing harmful PCBs, a family of highly toxic chemical compounds, under a central policy that upholds quick action in regard to processing PCBs into a non-hazardous form and calls for strict assessment and management should the continuous use of equipment containing or generating PCBs remain necessary.

In fiscal 2005, in order to assess the quantity of processed PCBs, NTT Communications carried out an original and extensive equipment-weight survey in addition to its regular PCB surveys.

NTT Communications is conducting surveys regarding the use and status of asbestos at the building facilities (355 locations) that it owns or uses. Eight facilities for which sprayed asbestos was used are confirmed to have no problems of scattering, with less than standard value (0-0.81f/L: allowable maximum: 10f/L) at all of these facilities. In addition, at five of these eight facilities, elimination work is proceeding (partially completed), while with the remaining three facilities, we are assessing whether it is possible to eliminate the substance together with promoting as early elimination as possible. We are also investigating possible use and status of spraying material containing asbestos at our facilities.
