Study Reveals Paper Straws More Harmful to Environment Than Plastic

SEOUL: A recent government-commissioned study has found that paper straws are significantly more harmful to the environment than conventional plastic straws, scoring 6.33 times higher in carcinogenic impact during their lifecycle.

The report, disclosed by Rep. Kim Wi-sang of the People Power Party and commissioned by the Ministry of Climate, Energy and Environment, evaluated the environmental effects of four types of straws: conventional plastic, paper, biodegradable plastic, and bio-based polyethylene (bio-PE). Researchers assessed impacts from raw material production to disposal across 16 categories, highlighting that the carcinogenic impact figure is a modeled life-cycle measure rather than a direct cancer risk to users.

This study raises critical questions about the sustainability of alternatives to plastic, as paper straws also exhibited 2.04 times the acidification impact compared to their plastic counterparts. Bio-PE straws fared even worse, with a staggering 16.18 times the carcinogenic impact and 5.9 times the acidification impact. Biodegradable plastic straws were not exempt, showing 3.34 times the carcinogenic impact and 1.98 times the acidification impact.

As the world grapples with environmental challenges, this report could influence consumer choices and policy decisions regarding single-use products. The findings may prompt further investigations into the production and disposal methods of these alternatives, as well as discussions on more sustainable practices moving forward.
