Environmentally conscious water recycling plant

Nishinihon Kaden Recycle Corporation

The water recycling plant of the Nishinihon Kaden Recycle Corporation prioritises environmentally friendly initiatives.
In the process of disassembling and crushing home appliances (air conditioners, refrigerators, TVs, washing machines) and recycling the metals and plastics, we use a large amount of water for washing and density separation, especially for the finely crushed plastics. During the cleaning process, fine fragments and dirt get mixed into the wastewater, so we use chemicals such as flocculants to form lumps, which are then removed by sedimentation in a tank. This treated water is then used again for cleaning. In addition, because high-purity water is needed for density separation, we carry out advanced treatment using activated carbon and ion exchange resin to produce recycled water. This water is then used again in the same process. According to data from the past three years, the amount of recycled water has reached around 80% compared to the amount without this measure, and this has resulted in the saving of around 35,000 to 40,000 tons of water received per year.
Nishinihon Kaden Recycle Corporation will continue to fulfil our role as a company that contributes to the creation of a sustainable, resource-recycling society.
