A solar-powered filter system able to capture and break down plastic could help reduce the amount of waste entering the oceans.
Developed by a team from KTH Royal Institute of Technology, the filter system membrane is made up of an array of nanoscale wires covered in a semiconductor material. As the filter captures the microparticles of floating plastic, the semiconductor material uses harvested solar radiation to speed the natural photocatalytic oxidation process and break down the plastics.
The team plans to test the filter in household wastewater pipes and wastewater treatment plants.
