Paper Straws May Harm Environment More Than Plastic
Key Points:
- A South Korean government-commissioned life-cycle analysis found that paper straws have over six times the cancer-related environmental impact of plastic straws and about double the acidification impact.
- Bio-based polyethylene (Bio-PE) straws were found to have the highest carcinogenic impact, exceeding plastic straws by more than 16 times.
- Conventional plastic straws scored lowest in 10 out of 16 environmental impact categories, including climate change and human toxicity, while bio-PE straws ranked worst in 10 categories.
- Researchers emphasized that all types of disposable straws are difficult to recycle and recommended that venues provide straws only upon request to reduce waste.
- A South Korean lawmaker advocates for policies aimed at substantially reducing disposable product use overall, rather than an outright ban on plastic straws, focusing on emission-based environmental risks throughout the product lifecycle.
