At Daiwa plants, sludges that are physically or scientifically removed from wastewater go through dehydration and drying processes. They are then recycled as cement materials.

Waste solvents are cleaned through a distillation process and are reused in our own plants as washing fluid for manufacturing components. We have named this fluid “Eco Cleaner.” The original fluid developed in-house also works to enhance employee consciousness of recycling.
