Project investigates ways to remove plastic in wastewater


An EU-funded project to harness the Sun’s radiation to rid the oceans of plastic begins with a system developed at the KTH Royal Institute of Technology in Sweden.

The new technology will be used to break down micro-plastics from personal care products and tested for implementation in homes and wastewater treatment plants.

While exposure to sunlight can degrade plastics into harmless elements, it’s a slow process. In some cases, plastics can take several years to decompose.
Joydeep Dutta, chair of the Functional Materials division at KTH, says this system will speed up that process by making more efficient use of available visible light and ultraviolet rays from the Sun.
