Synthetic Polymers and the Environment

Description

Synthetic Polymers and the Environment — Chemistry Chapter Presentation Slides: 12 | Audience: High school / early-college chemistry, environmental science, or materials science students | Format: Editable PowerPoint (.pptx) | Series: Chapter 6 of The Chemistry Spirit (Polymers) The chemical resistance that makes plastic bottles useful is exactly the property that makes them a problem once they're thrown out. This chapter follows synthetic polymers past the point of purchase — into oceans, incinerators, recycling streams, and depolymerization reactors. Students learn why "just switch to paper" doesn't work (a real German study shows it's worse on four axes), decode the number-inside-the-triangle recycling code, weigh the trade-offs of incineration by looking at what actually comes out of the smokestack, and finish with a document on used tires that reframes a familiar eyesore as a serious public-health issue. Chemistry, but with the receipts.
