Blister pack recycling

Blister packs (used for pills, supplements, gum, small electronics, batteries, etc.) are notoriously difficult to recycle because they combine plastic + aluminum fused together. This makes standard municipal recycling unsuitable.

What Counts as “Blister Packs”

Blister packs typically include:

  • Pharmaceutical pill packs (plastic bubbles with foil backing)
  • Vitamin & supplement packs
  • Gum packs (e.g., Trident, Dentyne)
  • Retail item blister shells (electronics, cosmetics—usually PET plastic)

Important difference:

Type of packageRecyclable?Notes
Pill blister packs (plastic + foil)Hard to recycleNeed specialized programs
All-plastic blister shells (PET)Often recyclableCheck local rules for #1 plastic
PVC blister packsRarely recyclablePVC is restricted in most programs

Are Blister Packs Recyclable? (Short Answer)

Most cities do not accept pill blister packs.
Why? Because they must be mechanically separated (plastic vs aluminum) and cleaned.

Only specialized recycling programs handle them.


Where to Recycle Blister Packs

Currently, consumer-friendly options:

1. Terracycle – Medicine & Supplement Blister Pack Recycling

  • Most reliable program in the U.S.
  • You buy a Zero Waste Box, fill it, and ship it back.
  • Accepts: All pill blisters from meds + supplements.
    ✔ Pros: Works nationwide, high recycling rate
    ✘ Cons: Not free (boxes ~$90–$130)

2. CVS Blister Pack Recycling (Pilot Programs)

  • Some CVS locations accept empty pill blister packs via Terracycle.
  • Availability varies by state.

3. Local Household Hazardous Waste Facilities

Some states accept medical packaging under “healthcare plastics.”
Check your county’s HHW drop-off.

How Blister Packs Are Recycled (Real Process)

Specialized facilities use:

Step 1 — Mechanical Shredding

Blisters are shredded into small flakes.

Step 2 — Heat or Pressure Separation

Plastic and aluminum layers are separated using:

  • Thermal delamination
  • Density separation
  • Eddy current separation

Step 3 — Material Recovery

  • Plastic (PVC, PET) → turned into industrial plastic pellets
  • Aluminum foil → melted and reused

Step 4 — Waste Minimization

Any unrecyclable residue is used in waste-to-energy processes.


How to Prepare Blister Packs for Recycling

✔ Empty all pills completely
✔ Leave the foil attached (don’t peel)
✔ Do not rinse with water (not required)
✔ Remove cardboard outer packaging (recycle separately)
