The different parts of the toothbrush can be disassembled for proper disposal.
The Bamboo handle is 100% biodegradable & may be composted after use.
The bristles however are not biodegradable & must be removed before disposal with pliers.
We've discovered most if not all toothbrush bristles to be very small and lightweight resulting in curbside recycling possibly not working. Example, if one were to simply throw the bristles into a big curbside recycling bin, they can easily get lost and will not make it through the recycling process.
The best option is the Colgate Oral Care Recycling Program, a collaboration between Colgate and TerraCycle. This organization accepts not just old toothbrushes but used toothpaste tubes and dental floss containers! These items are each made from multiple types of materials, which means they most likely can't be processed by your town's regular recycling plant.
TerraCycle program will take the components apart for you at no charge.
Step 1 - Find a box.
Step 2 - Fill up the box.
Step 3 - Print the UPS label from their website.
Step 4 - Slap it on.
Step 5 - Send off your plastic waste.
Step 6 - Reduce - Reuse - Recycle
Once they receive your toothbrushes, floss containers & toothpaste tubes they are broken down into their plastic parts, shredded & melted into a hard plastic that's used to make new products.
If no solution can be found, the bristles will have to be landfilled. In total, this will result in less than 0.01 ounces of plastic waste (a drastic improvement from regular plastic toothbrushes).
