In this segment of a science‑focused podcast, a polymer scientist outlines how polymers are integral to everyday items—from shampoo and plastic containers to the DNA that makes up our bodies—highlighting their pervasive presence in modern life. He shares his personal journey, noting that his fascination with polymers led him to earn a PhD in polymer science. The discussion then shifts to bioplastics, emphasizing that not all polymers share the same end‑of‑life characteristics. He contrasts traditional petrochemical‑derived plastics, which are typically non‑degradable, with emerging bioplastic materials that can be designed for different degradation pathways, such as compostability or bio‑degradation, underscoring the potential for more sustainable material choices.

So polymers are in your shampoo, they're in the container that makes the plastic, the DNA in your body, and they're all around us. So I became really interested in polymers and how they influence our lives, which was why I got a PhD in polymer science. Started discovering bioplastics and just really understanding, you know, there are polymers that have different end of life, polymers that can be made into plastics, different end of life. than what we're familiar with, with traditional petrochemical polymers that are traditionally in our plastic containers that don't degrade.
