The PlanetCare filter is a simple, yet efficient filter for removing microfibrers from washing machine waste water. The central part of the system is microfiltration of water based on electrically charged fibres and membrane nano-technology with a self-cleaning function.
Main activity field:
The Centre for Validation Technologies and Analytics at the Slovenian National Institute of Chemistry performed two tests, one with and one without PlanetCare filter incorporated into the washing machine. One washing cycle produces 1403,95mg of plastic fibres that go through the drain water into the sewing system. The incorporated filter was able to collect 1105,59mg of plastic fibres in the first washing cycle.
