Reduction of Environmental Impact throughout the Product Lifecycle

 The Yamada Denki Group facilitates environmentally-sustainable efforts by customers and society-wide efforts to reduce environmental impact by supporting households' efforts for energy conservation, energy creation and energy storage through the sale of energy-efficient home appliances and photovoltaic power generation systems, and also by establishing systems to recycle and reuse used home appliances.

Reuse of Home Appliances and PCs

 The Yamada Denki Group started the reuse business concerning home appliances in fiscal 2001, and the reuse and recycling business concerning personal computers in fiscal 2007.

 In fiscal 2017, we handled around 100,000 units of home appliances (TVs, refrigerators, washing machines and dryers) and around 330,000 units of PCs in the reuse business. In order to enable customers to reuse used home appliances without worries, we have established original recycling systems for cleaning used appliances and checking their functions as well as offering a 24-month guarantee at the longest upon selling them, in collaboration with CIC, a group company. Meanwhile, we provide personal computer reuse and recycling services together with INVERSENET.

Recycling of Ink Cartridges and Mobile Phones

 Yamada Denki is promoting recycling by installing ink cartridge collection boxes in each store. We make donations using funds obtained through the collection of cartridges (10 yen per cartridge). In fiscal 2017, we collected around 0.98 million cartridges and donated 7,047,390 yen to the Foundation for Orphans from Automobile Accidents. We will continue this initiative, thereby promoting such activities as offering support for disadvantaged children, assisting the creation of a sound material-cycle society, and reducing waste and CO2 emissions through the reuse of empty ink cartridges. Additionally, we collect used mobile phones in cooperation with our group company, INVERSENET, and extract rare metals therefrom, aiming to contribute to stable supply of rare metals.

CO2 Emissions from the Use of Electricity

 The Yamada Denki Group has continuously tried to reduce CO2 emissions from business activities.


 We properly dispose of waste from stores and used home appliances recollected from customers that are not subject to the Act on Recycling of Specified Kinds of Home Appliances in accordance with relevant laws.

 We also properly disposed of waste in compliance with relevant laws and regulations in fiscal 2017.

Environmental Consideration in Business Operations

 Yamada Denki has been promoting activities to reduce CO2 emissions and other environmental impact at stores and in the process of logistics.

Conclusion of Partnership Agreement on Household Energy Conservation with the Tokyo Metropolitan Government

 Yamada Denki concluded a partnership agreement with the Tokyo Metropolitan Government to further promote household energy conservation. As the first specific initiative under the agreement, we have been offering cooperation for a campaign to promote an energy saving movement among households through a shift to LED bulbs since March 2018.

 We consider that coexistence with the global environment is the basis of sustainable growth of our society and economy. Therefore, as our efforts to reduce environmental impact through business operation, we have been promoting energy conservation, energy creation and energy storage at homes and have been placing the emphasis on the reuse and recycling business of used home appliances and smart house business, thereby assisting customers' environmental protection activities and contributing to the reduction of environmental impact of society as a whole.

 Starting with the cooperation with the Tokyo Metropolitan Government's initiative, we will further endeavor to create a general environment that is even more eco-friendly and make customers feel reassured about their health and everyday lives.

Acquisition of ISO14001 Certification for the Headquarters

 In January 2011, Yamada Denki obtained ISO14001 environmental management system certification for the headquarters in Takasaki. To reduce the environmental impact from our operational activities, we have been actively conducting measures for saving energy and resources at stores, including the introduction of renewable energy use, etc. In fiscal 2017, Yamada Denki obtained certification by satisfying ISO14001:2015 specification requirements.
