Summary

A new study from Spain’s Autonomous University of Barcelona reveals that tea bags made from nylon, polypropylene, and cellulose release billions of micro- and nanoplastic particles when steeped in boiling water.

These particles, which can enter human intestinal cells, may pose health risks, potentially affecting the digestive, respiratory, endocrine, and immune systems.

Researchers urge regulatory action to mitigate plastic contamination in food packaging.

Consumers are advised to use loose-leaf tea with stainless steel infusers or biodegradable tea bags to minimize exposure.

    So here’s one (potentially major) issue with these bags:

    While the bag catches a lot of microplastics, it is also leaving a lot more in your clothes because they were washed and contained in that bag. Where do those loosened microplastics on your clothes go? Either into the dryer (or outdoor line-dry) and expelled into the air, or you indoor line-dry your clothes and release more microplastics as you wear your clothes, breathing them in as you go about your day.

    So people would essentially be paying $35 a bag to slightly improve wastewater at the expense of increased air pollution. If you indoor line-dry those clothes, you put your own health (and potentially the health of those around you) at greater risk.

    The only non-polluting solution at this point is to not buy, wear, or launder any plastics-based fabrics. This includes polyester (a lot of people apparently are unaware of this).

      Very interesting! The Guppy Friend is only for use in the washer, then the micro plastics are collected in the end of the bag, which you take out like lint in a dryer, but I still think your point is very valid! I dry all my clothes on a rack, and I’ve only got two fleece shirts (never getting one again, these are many years old), so it’ll be thrown out when I no longer need it, but interesting point with the air particles!

      Still, how much micro plastics are we not getting from plastic cups, bottles, door wrapping etc? Too much lol

      I’ve read that using fleece/plastic clothing you already have is better for the environment than throwing them out, as the plastic is already there.

        Yeah, that’s the thing! It’s near impossible to quantify not only the number and size of plastic particles being released, but also from what sources and how impactful it is on our health over time. There are so many variables involved.

        I like the idea of the guppy bags, but honestly we need strict government regulation around the world to make a real difference in stopping plastic and PFAS pollution/contamination.

          100% agreed on the restrictions. I don’t think we can remove plastics by it’s entirety, but we can definitively limit its use dramatically!
