Episode notes
Plastic Recycling Is Mostly Ineffective
- Most materials like steel and cardboard recycle well, but plastic largely fails as a circular economy.
- Less than 10% of discarded plastic has entered the recycling process, which is expensive and often toxic.
Recycling Can Release Persistent Toxics
- Recycling plastic often releases toxic additives during mechanical processing, contaminating local environments.
- These persistent contaminants enter soil, water, and food systems and do not disappear.
Avoid Single-Use Plastics; Landfill If Needed
- Avoid unnecessary single-use plastics whenever possible to reduce harm and exposure.
- If unavoidable, landfilling may be less harmful than exporting waste where it will be processed unsafely.
