#13 bamboo toothbrushes

Bamboo grows very fast, so it is the perfect material for an item that needs to be replaced every three month. Unlike plastic. A plastic toothbrush is used for a couple of weeks and then stays on this planet for several hundred years, since it will not biodegrade. That makes no sense. Switch to bamboo. Plus: You can just burry the old brushes in the backyard. 

Before I reblog, I always do a little fact-checking and research first to make sure I’m not disseminating inaccurate information.

I found the above post to be a bit misleading. It says you can “just burry (sic) the old brushes in the backyard,” seemingly implying that the entire brush is biodegradable.

This isn’t the case. While it’s certainly a good step to buy a bamboo brush rather than a landfill-destined plastic brush, even a bamboo brush isn’t fully biodegradable.

I found that currently, no one has been able to create toothbrushes that are fully biodegradable because the bristles are typically made of some inorganic material like nylon — unless they use boar bristles. This doesn’t necessarily make boar bristle brushes the go-to option: some people who use these types of brushes complain of an odor, in addition to the fact that these brushes may not be considered vegan since they’re made with a hair harvested from an animal.

Within the realm of bamboo brushes, one of the seemingly best options is made by a company called Brush With Bamboo. According to their website, the bristles of their sustainably-made brushes are made with 62% castor bean oil and 38% nylon, rendering them “biobased, but still not biodegradable,” since nylon doesn’t decompose.

So if you bury your bamboo brush, sure, most of it will decompose. But the bristles won’t. In fact, most bamboo brush companies advise you to tweeze out the bristles before attempting to compost.

Sure, the bristles are small and seemingly insignificant, but you should know what you’re getting into before telling all your friends you’ve got a fully biodegradable toothbrush graveyard buried in your garden.

I’d be remiss not to include that there is one option, and it’s been around for centuries: the neem chew stick. It’s the only truly biodegradable option, since it’s made from a neem plant and is a literal stick. It’s exactly what it sounds like. To use it, you chew on the end of the stick until it frays into bristles, then you brush.

The downside? You have to chew your toothbrush down before you can use it. And when it comes to brushing your teeth, the more inconvenient it is, the less likely you are to do it. And one thing I really want to emphasize on my own blog is making more sustainable choices easier, not harder.

Until someone creates the perfect toothbrush — ergonomic, wallet-friendly, biodegradable, and not made from pig hair — it looks like the best option on the market is a bamboo brush. Just make sure to tweeze out those bristles before you toss them in the dirt.

Have you seen any other notable sustainably-made or biodegradable toothbrushes? My ears (and asks) are open.
