In case anyone wasn't clear, this is for drinking water/waste water systems. Not for cleaning up the ocean.

This sounds like a great, renewable, filter material that can be added (or replace existing filters) to a municipal water treatment plant. There's serious issues with microplastics getting into drinking water, and this could certainly help with that.

So normal filters don't remove micro plastic?

Most normal filters at the consumer level are made of the same plastics.

RO removes up to 99% of microplastics. Ceramic water filters, water distillation, and nanofiltration also remove microplastics.
