Can You Recycle Your Toothbrush? Everything to Know
Learn why toothbrush recycling is tough, what innovative solutions exist, and steps for eco-friendly oral care.
Can You Recycle Your Toothbrush?
Toothbrushes are daily essentials for oral hygiene—but what happens after their few months of use? Each year billions of toothbrushes end up in landfills around the world, raising significant environmental concerns. Recycling your toothbrush might seem straightforward, but the reality is surprisingly complex. In this article, we explore why standard toothbrushes are difficult to recycle, how specialty programs work, and what you can do to reduce toothbrush waste.
Why Is Toothbrush Recycling So Complicated?
The traditional toothbrush is deceptively simple in appearance but complex in structure. Most are made from a combination of plastics, nylon, and sometimes tiny pieces of metal. These mixed materials create significant barriers to standard municipal recycling.
- Material Complexity: A standard toothbrush handle is usually made of polypropylene or polyethylene plastic. The bristles are typically nylon, and the clusters of bristles are often secured with tiny metal staples inside the head.
- Separation Challenge: Most curbside recycling centers require materials to be separated in order to be effectively recycled. Toothbrushes are engineered to keep their parts tightly together, resulting in a product that’s labor-intensive for recyclers to dismantle.
- Low Economic Value: The effort and cost required to disassemble and process the components outweigh the relatively small amounts of raw material recovered, further discouraging recycling at scale.
These factors mean that used toothbrushes usually aren’t accepted in regular home recycling bins and instead get sent to landfill, where they can remain for hundreds of years without fully breaking down.
What Happens to Tossed Toothbrushes?
Plastic toothbrushes are remarkably durable—they can take up to 400 years to decompose. During that time, they may fragment into microplastics, polluting soil and water systems and threatening wildlife that mistake the small pieces for food.
This huge, persistent waste stream makes sustainable oral care a pressing concern for both consumers and environmental advocates.
How Toothbrush Recycling Works
Despite the challenges, some companies and recycling organizations have developed ways to recycle toothbrushes, but the processes are more involved than standard recycling.
Step-by-Step: Toothbrush Recycling Process
- Collection: Users must gather their old toothbrushes and, usually, mail them to a specialized recycling partner.
- Separation: In dedicated recycling facilities, machinery or manual laborers separate the nylon bristles from the plastic handle. The small metal staples are also removed.
- Processing: Each component is then handled differently:
- Metals are sent with standard metal recycling.
- Nylon bristles and plastic handles are cleaned, shredded, and processed into pellets.
- Repurposing: The resulting pellets are used to manufacture new items, including picnic benches, park equipment, bike racks, or even accessories and furniture. This upcycling turns oral care waste into new, useful products.
Because this process involves multiple tightly integrated materials, toothbrush recycling streams are limited, and not available through most local recycling programs.
Special Programs: TerraCycle and More
Several programs now make toothbrush recycling more accessible. Chief among them is the partnership between TerraCycle and major oral care companies like Colgate. Here’s how such programs generally work:
- Mail-Back Schemes: Consumers collect their used toothbrushes (as well as empty toothpaste tubes and dental floss packs) and mail them to a collection point using a prepaid shipping label.
- Drop-off Points: Some dental offices or retail locations act as community collection sites—findable via TerraCycle’s drop-off map.
- Accepted Items: These programs typically accept manual toothbrushes, electric toothbrush heads, toothpaste tubes and caps, dental floss containers, and some packaging. Brands or program specifics may vary, so always check.
What others are reading
Once received, these products go through the specialized recycling process. While not as convenient as putting an item in your curbside bin, these schemes offer a credible path to zero waste for your oral care routine.
Brand-Led Recycling Initiatives
Some companies have developed recycling programs specific to their products. For example, SURI provides prepaid compostable mailers to return used plant-based brush heads. Their process separates bristles from heads and copper fasteners, recycles each component, and either extrudes the plastics for 3D printing or reuses them in manufacturing new items. SURI’s focus is on minimizing planetary impact by favoring biodegradable and recyclable materials from the start.
Oral-B, Radius, and several eco-focused brands provide take-back or recycling options for their product lines—check each manufacturer’s website for details on participation.
Alternatives to Recycling: Reuse and Upcycling
If recycling your toothbrush isn’t feasible, giving it another life keeps it out of landfill longer. Toothbrushes have durable bristles and ergonomic handles that make them ideal for several practical uses after their oral care service ends.
- Clean grout, tile, and hard-to-reach kitchen nooks
- Scrub mud from shoes, bike cogs, or gardening tools
- Wash jewelry or intricate equipment parts
- Detail clean car interiors and dashboards
- Groom pets or remove hair from brushes
These reuse options extend the usefulness of toothbrushes, reducing the demand for new cleaning tools and saving resources.
Eco-Friendly Toothbrush Alternatives
Reducing waste at the source is often even more effective than recycling. For conscious consumers, several alternatives to the standard plastic toothbrush are now available:
- Bamboo Toothbrushes: Bamboo handles are biodegradable under the right composting conditions. The bristles are often still nylon, but you can remove and discard them separately before composting the stick.
- Plant-Based Plastics: Some companies use bioplastics made from cornstarch or castor bean oil—reducing fossil fuel inputs and, in some cases, making handle recycling or composting easier. Always read the product details to understand degradability.
- Replaceable-Head Toothbrushes: Toothbrush systems with detachable heads cut down on plastic waste, as users only replace the bristled part, not the entire handle.
- Electric Toothbrush Recycling: Certain brands provide head recycling or even full-device recycling, including the internal batteries and rubber components. Check the manufacturer’s recycling information when you buy.
Be aware, even with alternative materials or compostable handles, the bristles are often plastic-based unless the product states otherwise. Always remove the bristles before composting a bamboo toothbrush handle to avoid microplastic contamination.
How to Recycle Your Toothbrush: Step-by-Step Guide
- Identify Program Availability: Visit the TerraCycle website or your toothbrush brand’s recycling page to check if a mail-back or drop-off recycling program exists in your area.
- Collect Materials: Store used toothbrushes, electric heads, empty toothpaste tubes, and other eligible items until you have enough to make shipping practical or worth the drop-off trip.
- Prepare for Recycling: Rinse material slightly to minimize food or toothpaste residue. Most programs do not require deep cleaning as items are washed in the recycling process.
- Mail or Drop Off: Use the program’s provided shipping label or collection bag, or locate the nearest drop-off point for in-person delivery. Consider coordinating with friends, neighbors, or community groups to maximize efficiency.
- Repeat & Reduce: Consider moving to toothbrush types that are easier to recycle or require replacement of only part of the brush (like replaceable-head systems).
The Bigger Picture: Reducing Oral Care Waste
While recycling is an important tool for minimizing landfill, the best approach is often to tackle waste at its source. Here are some tips for reducing the environmental impact of your oral hygiene routine:
- Opt for a toothbrush made with recycled or plant-based materials wherever possible.
- Switch to toothpaste tablets in compostable or recyclable packaging to reduce tube waste.
- Choose products from brands that participate in recycling schemes or use eco-friendly design.
- Use each toothbrush as long as it remains effective—usually 3 to 4 months, or as recommended by dental professionals.
- Encourage your community, school, or workplace to participate in organized oral care recycling drives.
