However, a South Korean government-commissioned study suggests that switching materials does not always mean reducing environmental harm. The study, released in October 2026, assessed four types of disposable straws: conventional plastic, paper, biodegradable plastic, and bio-based polyethylene (bio-PE). Researchers evaluated their impacts across 16 categories, covering their life cycle from raw material production to disposal. Results showed that paper straws had 6.33 times the potential carcinogenic impact and 2.04 times the environmental acidification impact of conventional plastic straws. Conventional plastic straws recorded the lowest environmental impact in 10 of the 16 categories examined, including climate change and particulate pollution. However, these findings do not mean paper straws directly increase a user's cancer risk by sixfold. The carcinogenic impact figure is a model-based estimate of potential effects associated with emissions throughout manufacturing and disposal, not a measure of the risk from drinking through a straw. Researchers also found that recycling remains difficult for all straw types. Their small size makes them challenging to sort, while coatings and adhesives can complicate the recycling of paper straws. The findings highlight an important principle in environmental science: assessing sustainability requires examining a product's entire life cycle, not just the material it is made from. #straw #environment #plastic
