A research team from the University of Waterloo has developed a new material that can absorb more than eight times its weight in oil. This innovation offers a new way to prevent groundwater pollution from spills or accidents.
Led by Dr. Tizazu Mekonnen, a professor in the Department of Chemical Engineering, the team designed a polymer foam that turns into a gel upon contact with oil.
“The current technology for oil capture is lagging,” said Mekonnen. "Preserving our environment is crucial, which is why developing advanced technologies like this polymer is essential for remediating future groundwater contaminants that involve oil.”
The polymer material resembles a yoga mat’s spongy texture but becomes a semi-solid gel-like substance that seals oil in and prevents leaks. The material is also lightweight, easy to transport, and oil trapped in the gel can be completely recovered through a secondary process.
Applications for use include practical settings for electric transformers and oil storage facilities that face groundwater leak risks due to unexpected accidents or natural disasters such as tornadoes, earthquakes, and hurricanes. The Waterloo team worked with Ontario-based manufacturer Albarrie Canada who provided financial and technical support for the project.
