Howa Co., Ltd. handles most of the washing processing of our trading manufacturers. It removes impurities from the sewage generated during the denim washing process, and drains it after clearing company standards that are much more strict than the standards of laws and ordinances. Also, it has made various efforts such as developing own eco-bleach, which considers the environment of the bleaching agent used when decolorizing denim, and in recent years, using ozone to reduce chemical substances.
