Kind: research · Impact: medium

## In brief

- Experiments using landfill leachate found that plastics labeled "biodegradable" differ widely in how fast they break down.
- Some such plastics degrade readily while others persist for long periods.
- A collaborative research team led by KAIST conducted the experiments.

## Why it matters

Science readers working on polymers, waste management or environmental persistence should note that the "biodegradable" label does not guarantee rapid breakdown in landfill conditions.
