“Beyond costs savings for consumers who no longer need to purchase detergents and softeners, DIRO’s benefits are significant. Cutting down on chemical detergents leads to lower acidification in water sources. The DIRO system reduces energy consumption by up to 40 percent. And the service life of machines will be longer because, without detergent, no lime-scale buildup occurs.

If this innovation or others like it penetrates 10 percent of the target market by 2027, the global greenhouse gas emissions would be reduced with 21 million tons of CO2e annually.”
