Promotion of a Recycling-oriented Society

Promotion of a Recycling-oriented Society Promotion of a Recycling-oriented Society

We are active in the 3Rs and Mobile Device Recycling (reduce, reuse, and recycle) to make efficient use of resources in our business operations, promoting sustainable production and consumption activities and contributing to reduced environmental impacts and the realization of a recycling-oriented society.

The 3R's
(reduce, reuse, recycle)

3R initiatives (Reduce: reduce the volume of waste, Reuse: use repeatedly, Recycle: utilize once again as resources) have started in various settings to achieve the goal. We are working to achieve a recycling based society by promoting 3R activities.
At our affiliated company SB C&S, we design and develop environmentally friendly products (PCs / mobile peripherals) through our eco-design process, such as reducing the resources materials making products smaller and lighter, and also facilitating the reuse and recycling of parts by making the structure easy to disassemble.

The 3R's (reduce, reuse, recycle)

Promoting 3R activities
in mobile telephone services


We strive to reduce the amount of paper resources used in the sales of mobile information devices by making individual packing boxes smaller, converting instruction manuals and other bundled documents to applications, and utilizing iPads in our stores.

Moreover, to replace the conventional paper-based invoices, we launched an “online charges guide” starting with the October 2006 statement which allows users to view electronic billing statements over the Internet from a SoftBank mobile telephone or PC. This is provided as a basic service to all individual subscribers.


We promote trade-ins of previously used and functional mobile telephones and tablets during model upgrades, etc.

Processing all mobile telephones and tablets which are still usable as waste material increases the environmental loading. Because even older devices which are no longer in demand within Japan can be effectively put to use overseas, trade-in devices are refurbished and reused primarily in developing countries.


Collection of used mobile telephone handsets and battery packs, etc.
Mobile Recycle Network

As a member of the Mobile Recycle Network (MRN), an organization which engages in mobile telephone and PHS recycling activities, we promote the collection of used mobile telephone handsets, battery packs, chargers, USIM cards, and other items regardless of the mobile telephone carrier or manufacturer. To make customers feel at ease and encourage cooperation with recycling efforts, mobile telephone handsets are processed for recycling by being physically destroyed with a “mobile telephone punch” during collection. In FY2022, we collected 2.22 million used mobile phones for reuse and recycling.

Mobile Recycle Network (Telecommunications Carriers Association) (in Japanese)

Promoting resource recycling

As part of our product stewardship efforts intended to reduce environmental loading, used mobile telephone handsets and battery packs are collected and go through recycling processing to recover the rare metals (palladium, cobalt, etc.), gold, silver, copper, and other resources that they contain. In addition, the remaining by-products (slugs) of the recycling process are used as raw materials for concrete cement while the plastic materials from the handsets are recycled as supplement fuel and recycled plastics.

Besides mobile telephones, we also promote the recycling of used cables, switching equipment, utility poles, and other telecommunications equipment waste material when upgrading and removing networking equipment.

Implementing educational activities to teach about recycling

We hold “Recycle” environmental classes for children to learn the importance of recycling through the experience of disassembling cell phones.The class is designed for children to learn about the structure and materials of cell phones by actually disassembling them, and by using the disassembled parts to make crafts, to exercise their creativity and acquire knowledge about recycling while having fun. More than 700 people have participated in the class from April 2018 to the end of March 2023.

Reasons why mobile telephone recycling is required

Mobile telephone handsets, batteries, and chargers, etc. contain rare metals (palladium, cobalt, etc.), gold, silver, copper, and many other precious resources with limited output which are reused as raw materials for components in electronic devices.

Promotion of
plastic resource recycling

We promote recycling of plastics by collecting cell phones, smart phones and broadband routers.
In addition, in order to reduce plastic emissions and promote recycling, we monitor plastic waste emissions and consider reuse before disposal.

Implementing 3R activities

Promoting green purchasing

As part of our green purchasing efforts, starting in July 2004, as a general rule we changed all of our copy paper to recycled paper products which comply with the Green Purchasing Act. Moreover, Green Purchasing Act compliant products, Eco Mark products, and other stationery supplies with environmental labels are displayed on the purchasing web site to promote the green purchasing of products with a low environmental load.

Internal reuse of furniture
and stationery

Out of a concern for the environment, a reuse shelf was installed at the entrance of the Employee Support Center on the 19th floor of our headquarters office for the purpose of controlling waste discharge. We have implemented a mechanism by which furniture and stationery which are no longer needed by various departments are collected and internally reused.

Declaration of Zero Paper
for Internal Operations

Since April 2012, SoftBank Corp. has advanced a “Declaration of zero paper usage in internal operations” and has been proactively promoting a shift to paperless operations for all paper used in internal and external procedures as well as paper used in reports and meetings, etc. Also, in April 2021, we launched the “Digitalization of Stamping Project” to further promote paperless operations.

Achieving “100% paperless” operations in the customer support center

To eliminate the risk of information leaks due to the removal of printed media, individual operations which used a large volume of paper including manuals, memos, and notices were identified and improved to achieve “100% paperless” (zero paper usage) operations within the Customer Support Center which handles private customer information. As a result, annual paper usage has been reduced by 3.12 million sheets (equivalent to 240 tree logs) compared to previous years.

Buying back unnecessary
ICT equipment

At SB C&S, we provide an “ICT Lifecycle Service” which buys back unnecessary ICT equipment as part of our ICT equipment sales efforts. Out of a concern for the environment, the purchased products are reused and recycled*, waste discharge is controlled, and they are efficiently utilized as precious earth resources and socially recycled products.

    The recycling rate is approximately 99.6% in the case of desktop PCs.

Secured recycling box for collecting confidential documents

Instead of individually processing unnecessary documents as wastepaper, they are collected in a special locked security box for collecting confidential documents and batch dissolved at a later date to ensure security and recycling as toilet paper.

Resource-conserving initiatives

Appropriate use
of water resources

We recognize that water is both necessary for our business activities and an important resource for the local communities in which our business sites are located. Accordingly, we are addressing water risk and promoting the efficient use of water resources on a companywide basis.

The Environment Committee effectively manages water risk while conducting managerial supervision that ensures both companywide response to these risks and efficient water resource utilization.

Reducing energy and paper consumption through
White Work Style

SoftBank is engaged in reducing environmental impact through the application of information and communications technology (ICT). Through the implementation and proposal of a new way of working called White Work Style, work efficiency is improved while the volume of paper and energy consumed in day-to-day business is also reduced.

White Work Style is a service that allows employees to access internal work systems and software simply by connecting to SoftBank's network. Home PCs or personal iPhones and iPads can also be connected to an environment equivalent to the office PC, allowing flexibility in working time and location, such as teleworking from home, when on the move or from outside of the office.

Furthermore, with computer processing carried out on network servers rather than individual computers, computer power consumption can be reduced. By centralizing these servers at a large-scale data center, operational efficiency can be improved and overall power consumption will be reduced.

According to estimates by the Ministry of Internal Affairs and Communications, energy consumption from the use of office automation equipment and lighting can be reduced by 43% with the introduction of telework. Even when energy consumption at the home office is factored in, it is possible to reduce energy consumption by 14%. Through the promotion of teleworking, it is possible to reduce the amount of energy consumption throughout society. It is also an important initiative from an energy conservation standpoint.

Moreover, through the use of iPhones and iPads, documents stored on servers can be accessed as necessary. This has made it possible to reduce paper handouts and to present information in a more effective manner using video.

Implementation of White Work Style

Pollution prevention measures

Processing industrial waste in the appropriate manner

Industrial waste generated by our business activities is properly disposed of in accordance with the Industrial Waste Disposal Law.

Network center We aim to reduce the final disposal volume of unneeded telecommunication equipment and construction waste by reusing them.
Offices and distribution centers Asbestos used in our offices and facilities has been investigated and countermeasures have been taken to ensure that it is at a level that does not affect human health, and we are systematically improving and removing it. In addition, we are working to complete the treatment of polychlorinated biphenyl (PCB) within the deadline set by the Ministry of the Environment.

Raising awareness about industrial waste disposal

We provide practical training for employees involved in industrial waste processing that equips them with the knowledge they need to comply with laws and regulations and perform appropriate disposal. We deliver this training through e-learning-based instruction concerning proper industrial waste disposal and electronic manifest systems. In addition, we have set up systems, including consultation contact points.
