Overview
- A government‑commissioned life‑cycle study disclosed on Oct. 21 found conventional plastic straws had the lowest modeled environmental footprint in 10 of 16 categories, including climate change, particulate matter and human toxicity.
- The report modeled impacts from raw material production through disposal using national waste patterns and found paper straws had about 6.3 times the modeled carcinogenic impact and twice the acidification of conventional plastic.
- Bio‑PE and biodegradable plastic scored worse than conventional plastic on some measures, with bio‑PE showing about 16 times the modeled carcinogenic impact and nearly six times the acidification impact.
- Researchers said all straw types are hard to recycle in practice because their small size lets them slip through sorting equipment and water‑resistant coatings and glues hinder processing; the model assumed 73.6% of discarded straws are incinerated and 26.4% go to landfill.
- The report included a survey in which 87.5% of 1,001 respondents favored plastic straws, Representative Kim Wi‑sang called prior substitution policies 'greenwashing,' and researchers recommended stores stop default provision of disposable straws and offer them only on request.
