Episode notes
Plastic Is A Diverse Chemical Family
- 'Plastics' is an umbrella of polymers plus additives; different plastics serve distinct functions.
- Even plant-based polymers can be non-biodegradable and have similar risks depending on processing.
'Compostable' Often Ends In Landfill
- Many compostable or plant-based plastics need industrial facilities and won't degrade in typical public bins.
- Dr Stephanie often finds compostable coffee cups end up in landfill due to lack of industrial composting infrastructure.
Filter Water; Prefer Glass For Oils
- Use filtered water if possible and prefer glass bottles for oily drinks to reduce chemical migration.
- Consider reverse-osmosis or carbon filters mainly to lower chemical, not just particle, exposure.
