Environmental Activities and Results

We are working hard to conserve the environment, including reducing greenhouse gas emissions and making effective use of resources, in order to coexist harmoniously with society, our global community and nature ("Living Together").

FY 2021 Targets and Results

Category	FY 2021 Per Unit Targets	FY 2021 Per Unit Results
Energy use (drum plant)	Reduce 2% year on year	Reduced 0.5 %
Energy use (facilities other than the drum plant)	Reduce 2% year on year	Increased 13.2 %
Industrial waste generation	Reduce 1% year on year	Reduced 0.8 %
Water use	Reduce 1% year on year	Increased 5.5 %

Energy Conservation Efforts

Since the air conditioning systems are the biggest users of electricity in the plant, we switched to high-efficiency models and assigned managers of each unit to thoroughly manage their operation. We also introduced an energy management system to the plant that monitors areas where energy consumption is particularly high, so we can "see" how much energy is consumed on the system's monitor screen. This has enabled us to identify wasted electricity when production lines aren't running and reduce power consumption. This system has been rated A in the third-party evaluation and certification program for energy management systems established by Dongguan City to reduce energy consumption at companies that use more than eight million kwh per year.

Efforts to Reduce Industrial Waste

We are actively adopting green purchasing practices to reduce the generation of waste at the source. For example, we switched from disposable cardboard boxes to reusable plastic cartons for parts deliveries. This significantly reduced the amount of cardboard waste. We have also established an online database system that allows each department to post pictures and specifications of work desks, lockers, and other equipment they no longer need to encourage reuse and reduce waste. In 2020, 316 items were reused via this system.

Efforts to Reduce Water Use

We are taking various steps to reduce water use, such as switching to water-saving faucets. A gray water treatment system has been installed to reuse the water used for washing parts in the process as cooling water for boilers and chillers in the plant, reducing the annual consumption by 48,000 m³.

Green Production

Eco Action

We carry out various environmental activities under the banner, "Eco Action," during the four months from June to September. The slogan for FY 2021 was "Join the green manufacturing team. Save energy, make less waste." Working under this slogan, the plant's CSR department conducted 5S safety and environmental patrols and solicited proposals for improving the environment. It received 169 proposals from employees, out of which 154 were adopted.

Reducing VOC*¹ Emissions

Revamped exhaust gas treatment system for the removal of THF

In order to reduce VOC emissions, modification work was carried out from October 2019 to May 2020 to revamp the exhaust gas treatment system for the removal of THF,*² which is installed on the drum plant's production line. This enabled us to reduce VOC emissions by approximately 4,756 kg annually.

*1 Volatile organic compounds

*2 Tetrahydrofuran

Wastewater Treatment

We have an industrial wastewater treatment facility on the plant's premises and conduct voluntary water quality tests on a weekly basis in addition to third party tests performed every three months.

Green Production Certification

We are working to save energy as well as reduce waste and air pollutants in the production of printers, MFPs, and photoreceptor drums. In August 2020, we were awarded the City Class Green Production certification by the Dongguan Environmental Protection Bureau for our environmental efforts.
