Dairy processing requires large amounts of water—especially for cleaning and sanitation—which creates both environmental and cost challenges for the industry. This project focuses on finding a more sustainable solution by reusing “condensate of whey” (COW) water, a byproduct that is typically discarded despite being only lightly contaminated. Researchers will test an innovative technology called atmospheric cold plasma, which can safely kill microbes and enhance water with natural antimicrobial properties, making it suitable for reuse in cleaning processes.

The study will evaluate how effectively this treated water can replace fresh water in cleaning systems without compromising food safety. If successful, the approach could significantly reduce water use, lower costs, and decrease environmental impact in dairy processing. Ultimately, the goal is to support more sustainable, efficient dairy operations by turning a waste product into a valuable resource.
