Water Recycling

Industrial Wastewater Recycling

In addition to petroleum shortages, today there is a serious concern globally with the shortage of water. Countries, especially South East Asia, are strengthening their controls over their fresh water supply and are treating it as a precious resource. YKK Group is supporting these efforts by reusing cooling water, utilizing rainwater effectively and recycling factory wastewater in production.

Expanding Quick Dyeing Technology Around the World

The fastening business includes a dyeing process, which adds color to tapes, chains and other products. Dyeing machine water is heated and pressurized with steam to help ensure that the dyes are absorbed into the material. We have made improvements to our dyeing technology, which has enabled us to reduce the amount of steam used for dyeing by 25% and wastewater by 50%. In addition, we were able to significantly shorten the time required to complete the dyeing process. We are in the process of adopting a quick dyeing method at our plants around the world. We are currently using this method at 19 plants in 16 countries.
