I’ve never been one to wear sequins or glitter. They’re a bit too flashy for me, but I was alarmed when I recently read how devastating they are for the environment. Made of plastic with a shiny metallic coating, they’re non-biodegradable and will sit in the landfill for hundreds of years, possibly shedding harmful micro plastics into the soil.

As often happens, reading that fact led me down a number of other rabbit trails. I discovered that ancient sequins, made of gold, have been unearthed in archeological sites from Pakistan to Egypt including heaps of them scattered in King Tut’s tomb and sewn in flower shapes on his ceremonial robe. I also learned about modern day attempts to produce sequins that are biodegradable. So far, however, those haven’t been able to withstand heat and moisture making them unsuitable for use on clothing. Perhaps someday though.

All of this led me to wonder about the biodegradability of the kinds of fabric that we commonly wear. Here’s what I learned about how long it takes for different fibres to decompose:

Cotton:  1 week to 5 months. Denim, which is a much hardier cotton, takes 10 to 12 months.

Linen:  as little as 2 weeks

Hemp:  2 weeks

Wool:  3 to 4 months

Bamboo:  4 to 6 months

Silk:  1 to 4 years

Nylon:  30 to 40 years

Polyester:  20 to 200 years

Spandex:  up to 200 years

Acrylic:  200 years

Clearly, natural fabrics are better for the environment. Not only do they decompose much more quickly, but they also require much less processing to turn them into fabric in the first place. Did you know that they’re also better for you? Natural fibres are soft, strong, breathable, and don’t irritate sensitive skin.

So, am I planning to go all-natural and stop wearing synthetic fabrics? Probably not. That would be pretty difficult to do, but as one who wants to shop ethically, one thing I will continue to do is to shop second-hand and keep those synthetic fabrics out of the landfill longer. And I probably won’t be wearing any sequins!
