Reusing and recycling telephones, batteries, and personal computers
NTT East and NTT West both collect compact rechargeable batteries (NiCd, Li-ion batteries) from used telephones and cordless phones, toner cartridges used in fax machines, and other materials to reuse as resources.
NTT East and NTT West also offer an IT Equipment Collection Service to collect and reuse computers no longer required by businesses. After completely erasing data stored on internal computer hard disks, the computers are purchased as used computers and reused as commercial products, helping to prevent information leaks, reduce waste, and cut disposal costs.
In fiscal 2009, the NTT Group as a whole recovered 3.54 million communications devices, 6.05 million batteries, and 3.03 million chargers and other peripherals from customers.

Office paper consumption reduced nearly 20% with authentication-based printing
In May 2009, NTT DATA started offering [u:ma], an authentication-based print solution that uses a dedicated [u:ma]-G card reader compatible with a range of smart cards to restrict printing jobs to those required by authenticated users. The system prevents waste from unwanted or mistaken printing jobs, and contributes to an average reduction of over 20% in paper usage.
