Canada's Largest Engineering School

An international research team led by Waterloo Engineering has found a way to turn plastic waste into the main ingredient in vinegar using sunlight.

Their discovery could help reduce plastic pollution, especially in water, while also producing acetic acid, a chemical widely used in food production, chemical manufacturing and energy applications.

Work by researchers at Waterloo Engineering demonstrates how advanced algebra can help reveal the deep patterns and symmetry at the heart of music.

Dr. Olga Ibragimova, a former PhD student in computational mechanics, and Dr. Chrystopher Nehaniv, a professor of systems design engineering, used group theory - a branch of mathematics that studies symmetry and transformations - to examine melody.

Dr. Mary Wells received an appointment to the Order of Ontario, the province’s highest civilian honour, in recognition of leadership that advanced education, research and access to engineering across the province.

Wells, dean of the Faculty of Engineering at the University of Waterloo since 2020, was named among 30 appointees for 2025 by the Honourable Edith Dumont, lieutenant-governor of Ontario and chancellor of the Order of Ontario.
