Plastic Pollution Meets Its Match in a Sun-Driven Approach

Quick Smiles:

• University of Waterloo team converts plastics to vinegar using sunlight.
• Bio-inspired process works on PVC, PP, PE, PET, even mixed.
• Eco-friendly method fights ocean pollution without extra emissions.

PhD student Wei Wei led researchers at the University of Waterloo in discovering a sunlight-powered way to transform plastic waste into acetic acid, vinegar’s key ingredient.

This photocatalysis breakthrough, inspired by fungi, embeds iron in carbon nitride to drive reactions in water, ideal for aquatic microplastic cleanup.

“Our goal was to solve the plastic pollution challenge by converting microplastic waste into high-value products using sunlight,” said Dr. Yimin Wu, professor of mechanical and mechatronics engineering.

The process yields acetic acid from common plastics with high selectivity, supporting food, chemical, and energy uses while promoting circular material strategies.

“Both from a business and societal perspective, the financial and economic benefits associated with this innovation seem promising,” said Roy Brouwer, executive director of the Water Institute.

“This method allows abundant and free solar energy to break down plastic pollution without adding extra carbon dioxide to the atmosphere,” Wu adds.
