The Invisible Export: Purifying the Domestic Drain

Welcome back to the Project Clean Up (PCU) weekly newsletter! Our Point-of-Origin Challenge continues. We have successfully tackled the visible waste in the apartment—the food scraps and the bulky boxes. But what about the waste we cannot see?

The average apartment washing machine releases over 700,000 microscopic plastic fibers into the wastewater system per load. Add in the chemical runoff from legacy cleaning products, and the domestic drain becomes a primary pipeline for environmental contamination. The municipal water treatment plants downstream are not designed to catch particles this small.

We cannot ask a tenant to install a loud, pressurized reverse-osmosis system. Instead, we must alter the physical state of the water before it leaves the sink. We are doing this through the elegant science of Biomimetic Flocculation.
