Innovating for a Cleaner, Greener Future

Plastics have revolutionized modern life, yet they now drive a growing environmental and human health crisis. This isn’t just a pollution issue, it’s a systems challenge.

Solving it requires rethinking how plastics are designed, used, and recovered. The Wrigley Institute’s Future of Plastics Initiative advances forward-thinking, interdisciplinary approaches while keeping society at the heart of meaningful solutions.

Project Spotlight: Plastics Made from Seashells

With the help of a Wrigley Institute Faculty Innovation Award, Eunji Chung is developing a plastic made with calcium carbonate from ground seashells.

Inspired by Chung’s research into medical devices, the new substance is both biodegradable and biocompatible, meaning that it is not toxic to humans or animals if ingested.

“Even in our lab, everything is single-use plastic because everything has to be sterile. Nothing can be contaminated. It all just started to feel very overwhelming for me personally, and I had to find a solution.”
