Resources saving and Recycling

Reduction of environmental impacts
(Reduction of negative output)

Waste material of the package film will be plastic bag (Kawagoe Plant)

At the Recycle Center in Kawagoe Plant, we collaborate with business partner to recycle the stretch film for package which is discharged in this plant into plastic bags, then reuse as trash bags. By recycling 644 kg of the waste film material in the fiscal year ended March 31, 2022, resources were saved, and 1,550 kg of the CO₂ emission could be reduced. These recycled plastic bags are used not only at the Kawagoe Plant, but also at other Offices, including our headquarter and Myogadani Office.

Food wastes will be used as the renewable energy (Kawagoe Plant)

In the company cafeteria in Kawagoe Plant, we have been devised to reduce the food loss. Generated food wastes despite the effort had been used for thermal recycle by incineration, but we newly contracted with a company which generates renewable energy from food waste, then led to biogas power generation by methane fermentation of the food waste from cafeteria. Incineration residue is not generated, so it can be contributed to the reduction of final disposal volume.

Process from food waste to renewable energy

Example of Activity for Efficient Use of Resources
(Kawagoe Plant)

We changed handling method of the "IPA (isopropyl alcohol)" used for cleaning of the production machines from disposing to recycling after use. Moreover, we can carry out the waste solution when carrying in the recycled solution, resulting energy can be saved for transportation and CO₂ can be reduced.

Recycle Promotion Activities by Separation Dismantling
(Kawagoe Plant)

The trial products which performance evaluations had been conducted during development were dismantled and disposed. At that time, we exchanged information with recycling companies to specify the dismantle level which can be recycled easily. At the collecting location, the valuables prices for each type of IC, circuit, material, etc, are posted, so that it improves awareness of employees for recycling.

Example of increase in classification awareness
by numbering garbage bags (Kawagoe Plant)

Numbers are assigned to respective workplaces and the numbers are indicated in all garbage bags to enable identification and feedback to the division concerned when there is a classification mistake. In regard to items which mistake occurred, the worst 10 classification mistakes are notified in the plant with the environmental education by e-learning.

At the parts procurement stage, we select materials that enable reducing the number of types of plastic materials used, not adhering to different types of plastic materials, not attaching resin film to packaging boxes, and promoting use of recycled materials. We select materials which are easily collected, classified, and dismantled.

At the design stage, we conduct the product assessments for the following items, and specify the target values for each item. We promote product development with focused on resource recycling.

1. Less weight, less volume
2. Recycling of resources, use of recycled parts
3. Increase in resource recyclability
4. Ease in manual dismantling and classification
5. Packaging
6. Environmental preservation
