The American Dental Association recommends we use a toothbrush for about 3 to 4 months and then replace it. Instead of amassing a collection of used toothbrushes to reuse for cleaning the crevices around the toilet, or worse, just tossing them in the trash, there's Preserve by Recycline.
The toothbrush -- designed with the help of dentists -- is made mostly from recycled Stonyfield yogurt cups (#5 plastic, which comes from various partner organizations, one of which is right here in Brooklyn). And when it's time for a new brush, you can send them back to Recycline in a postage-paid envelope they provide. They'll integrate them into plastic lumber for park benches and decks.
You can buy them in bulk or sign up for a toothbrush subscription on their site to ensure you get a new toothbrush every 3 months.
