In a stunning twist, recent studies reveal that glass bottles may additionally incorporate greater microplastics than plastic ones. At the same time as consumers frequently pick glass packaging believing it to be more secure and extra new studies suggests that cup bottles—especially reusable ones—can launch up to 2.5 times greater microplastic particles than their plastic opposite numbers.
This locating comes from a 2024 examine posted inside the magazine Environmental technology & generation. Scientists tested specific bottled water samples and found that reusable glass bottles shed microplastics from their caps, linings, and internal coatings, mainly after repeated washes or exposure to warmth. Shockingly, microplastic levels in a few glass bottles reached over 6 million particles in step with liter.
The main culprits? Now not the glass itself, but the polymer-based totally liners and seals used to save you leakage and preserve carbonation. While these additives degrade over time or via washing, they launch microscopic particles into the liquid.
Plastic bottles, even though no longer ideal, usually release fewer microplastics because of their unmarried-use layout and extra uniform material composition. However, both sorts of bins make a contribution to microplastic publicity—a growing fitness and environmental issue.
Experts now urge manufacturers to redecorate bottle additives and explore more secure, inert substances for closures and seals. For consumers, this discovery is a reminder that the cloth alone doesn’t guarantee purity.
Till more transparent labeling and safer designs come to be standard, switching to stainless steel or filtered faucet water may also provide a higher stability of health and sustainability.
