Microplastics can be filtered during washing, while schoolchildren have already invented ivy-based detergents.
Now, a startup in Taiwan has reinterpreted and patented an existing process so that industrial-scale washing can take place without the use of chemical detergents. Their device is installed prior to the inlet of the machine and treats tap water using electrolysis.
This generates nano-bubbles with negatively charged ions comprising one oxygen and one hydrogen atom. These hydroxide ions then penetrate into the textile fibres, removing stains and disinfecting the washing.
Integration into industrial settings could result in a 50% reduction in both wash times and water consumption. The process also spares textiles, increasing their lifespan.
Another startup is aiming to improve washing effects using shower water.
