Foam technology in denim washing production: A sustainable alternative for water and chemical reduction
Year: 2025
Type: article
Abstract: In the denim washing industry, water is the most valuable and heavily used resource for every process. As a result, the groundwater level is declining at a concerning pace. Additionally, the extensive use of water presents significant environmental challenges and barriers to achieving sustainability. Reducing chemical usage with lower water consumption is a considerable challenge to overcome. One of the most promising techniques is foam washing, which is used instead of water, and chemicals are dozed through the foam. As a result, the usage of water and chemicals is comparatively reduced. This study investigates how effective this process will be in the future denim washing industry. Trials of raw garments with foam in the bleaching and enzyme process proved to reduce water usage by an average of 60%. Additionally, as the foam trials were possible to run at room temperature, they contributed to lower CO2 emissions. These findings establish foam washing as a transformative, sustainable alternative for the denim industry.
