There is now a biodegradable toothbrush! 450 million toothbrushes get thrown away every year and most never biodegrade. World Centric now has biodegradable toothbrushes and travel cases that are made from Ingeo, a plant resin. The toothbrush is certified compostable when sent to a commercial composting facility. If you do not have a commercial composting facility, they will send you a prepaid envelope where you can send the toothbrush back for composting! The price is only $4.55 and worth the price to keep toothbrushes out of our landfills!
