In this article, we’ll delve into the recyclability of Invisalign, shedding light on what happens to these aligners after use and how you can contribute to reducing their environmental footprint. Whether you’re currently undergoing treatment or considering Invisalign as an option, understanding the sustainability aspect is a crucial step towards responsible dental care.

Recycling Options for Invisalign Aligners

Invisalign aligners are made primarily from a type of medical-grade thermoplastic called SmartTrack, which is designed for comfort, durability, and clarity. However, this specialized material complicates traditional recycling processes. Most curbside recycling programs do not accept Invisalign trays due to contamination concerns and the specific type of plastic used.

Despite these challenges, there are several avenues to responsibly recycle or repurpose Invisalign aligners:

  • Manufacturer Take-Back Programs: Some Invisalign providers or orthodontic offices participate in take-back programs where used aligners are collected and sent to specialized recycling facilities.
  • Specialized Recycling Services: Companies like TerraCycle offer mail-in programs specifically designed to recycle dental products, including Invisalign trays. These programs break down the plastic for reuse in other products.
  • Upcycling or Repurposing: Some individuals creatively reuse aligners for protective covers, molds for small objects, or craft projects, though this is not a recycling method per se.

It is important to avoid disposing of Invisalign trays in the regular trash when possible, as they contribute to plastic waste accumulation in landfills.

Proper Disposal Practices for Invisalign Aligners

When recycling options are unavailable, proper disposal of Invisalign trays minimizes environmental impact. Follow these guidelines to dispose of aligners responsibly:

  • Remove Attachments: If any dental attachments or elastics are present, remove them before disposal, as these may be made from different materials.
  • Clean the Aligners: Rinse the trays thoroughly to remove saliva and debris, reducing contamination risks.
  • Place in Sealed Bags: Seal the trays in a small plastic bag to contain any residual moisture and prevent contamination of other waste.
  • Dispose in General Waste: If no recycling options exist, dispose of the sealed bag in the general waste bin rather than flushing or littering.

Environmental Impact of Invisalign Waste

Although Invisalign aligners are small, the cumulative environmental impact is significant due to the volume of aligners used worldwide. Plastic waste from dental and orthodontic products adds to pollution and landfill burdens because of the following factors:

  • Non-Biodegradable Material: SmartTrack plastic does not biodegrade easily, persisting in the environment for decades.
