Resource Conservation and Recycling

Basic Approach

KOITO places resource recycling as one of the most important issues of its environmental conservation activities. Throughout its product life cycle, KOITO is actively working to effectively use raw materials, energy, and other resources, and to reduce water consumption and waste.
 The KOITO Group will continue to actively promote “Eco-friendly Manufacturing for People and the Earth,” and strives to realize a recycle-oriented society.

Effective Use of Water Resources

Recognizing the importance of water resources in production activities and the risks that future economic growth, population growth, and climate change would have on water resources, KOITO is working on the effective use of water resources and protecting water quality as a social responsibility and to reduce business risks.
 To reduce the water usage per unit*, KOITO worked on enhancing the awareness of employees toward water conservation and improving the efficiency of water consumption in the production processes. As a result, the water usage per unit in FY 2020 was 39% lower and the amount of water consumption was 25% lower than FY 2009.
 KOITO also conducted water quality monitoring on the wastewater discharged from production sites to prevent water pollution in rivers or other bodies of water into which production sites wastewater is discharged.
*Water usage per unit: The amount of water consumption (tons) per production output (million yen)

Efforts in Reducing Wastes and Recycling

KOITO is working on efficient recycling of materials (including waste, valuable materials, and recycled materials) discharged from all plants. After achieving zero-waste in all plants in 2002, KOITO has been promoting waste reduction by setting the waste generated per unit as an index for recycling, mainly of plastics, and for efficient use of resources in production.
Efforts to Reduce the Amount of Waste from Production Sites and the Waste Generated per Unit
KOITO generated 6,651 tons of waste from plants in FY 2020, among which 2,909 tons were processed as waste*.
 The waste generated per unit (the amount of waste per production output) was 0.133 tons per billion yen, which was 27% lower than the base year (FY 2009) due to the continuous efforts to reduce the loss of defective resins.
 Further, KOITO has also worked to improve recycling (reduce waste for thermal recycling), and the amount of resources recycled in FY 2020 was 6,253tons.
 
*Waste: generated material that requires processing costs, and the processing is outsourced to disposal businesses contractors
