EUROPE – Fresh research emerging from Europe suggests paper straws may harbor hidden environmental and health risks, contrary to initial assumptions.

As people shift away from single-use plastics towards more eco-friendly alternatives, paper straws have been gaining popularity as a seemingly greener choice.

In 2021, the European Union took steps to combat plastic pollution by enforcing a ban on select single-use plastics, which prompted the food and beverage industry to embrace more sustainable options.

Among these alternatives, paper straws stood out as a favorite due to their perceived biodegradability, taking only a few weeks to decompose compared to the 200-year lifespan of plastic counterparts.

However, concerns have arisen due to a study in the U.S. that identified ‘forever chemicals,’ scientifically known as poly- and perfluoroalkyl substances (PFAS), in straws made from plant-based materials like paper.

The worry is that by sipping beverages through such straws, consumers may unknowingly ingest PFAS, which, while not causing immediate harm, could pose health risks with prolonged exposure.

Most alarmingly, PFAS are notorious for their persistence, accumulating in the environment, animals, and humans, potentially leading to health concerns. This prompted Belgian researchers to explore PFAS in plant-based straws, a subject not previously investigated in Europe.

Eco-friendly image shattered

The study examined 39 straw brands made from bamboo, glass, stainless steel, plastic, and paper, searching for 29 different PFAS compounds. Astonishingly, the majority of brands (69%) tested positive for PFAS, with 18 different types identified.

Paper straws, which are often marketed as eco-friendly and sustainable, were found to contain PFAS in 90% of cases.

Bamboo straws followed closely, with 80% of brands showing PFAS contamination, while plastic straws were also tainted in 75% of cases. In contrast, no PFAS were detected in any stainless steel straws.

The presence of PFAS in paper straws raises concerns about their environmental impact and potential health risks.

Although PFAS concentrations were relatively low, the cumulative effect of ingesting these ‘forever chemicals’ over time remains unclear.

Dr. Thimo Groffen, an Environmental Scientist at the University of Antwerp and co-author of the study, highlighted that while small amounts of PFAS may not be immediately harmful, they can add to the body’s chemical burden, accumulating over the years.

Moreover, the study did not investigate whether PFAS leach from the straws into liquids, leaving questions about how much PFAS consumers could unknowingly ingest.

Truly sustainable alternative

In light of these findings, stainless steel straws emerge as a genuinely sustainable alternative. They can be reused, do not contain PFAS, and are fully recyclable.

As the world grapples with the ongoing issue of single-use plastics and their environmental impact, the search for truly eco-friendly alternatives continues.

The study’s revelations underscore the importance of thorough scrutiny and consideration when assessing the environmental and health credentials of seemingly green products, like paper straws.
