can you compost toothpaste tubes?
No — toothpaste tubes are laminated plastic and aluminum, and even the new recyclable ones are still plastic.
which bins can take it?
- hot pile no
- cold pile no
- worm bin no
- bokashi no
- tumbler no
- curbside no
- curbside: Organics carts are for food and yard material; packaging of any kind is a contaminant.
why?
A conventional tube is a sandwich of polyethylene layers around an aluminum foil barrier that holds flavor oils in and air out, and those layers cannot be separated, which is why the tube fails at recycling and composting alike. The newer all-HDPE tubes solve the recycling problem only — high-density polyethylene stays inert in soil for centuries.
watch out for
- Toothpaste itself is mostly water, hydrated silica, glycerin, and fluoride salts — a leftover smear does nothing good or bad in a pile, and it doesn't make the tube compostable.
what to do instead
The tube goes in the trash unless the brand sponsors a mail-back program; several oral-care companies run free postage-paid collection for brushes, tubes, and floss containers. Toothpaste tablets in glass or metal skip the tube entirely.
often confused with
- Toothpaste cartons — The outer box is plain paperboard and composts or recycles easily — it's the tube inside that fails.
quick answers
What about aluminum toothpaste tubes?
Solid metal tubes, the kind some specialty and imported brands use, can sometimes go with scrap aluminum. They're still not compostable, and most carry an internal plastic or epoxy lining.
Can I recycle the cap?
Caps are polypropylene and small enough to fall through sorting screens at most facilities. Leave the cap on if the brand's all-HDPE tube instructions say so; otherwise it's trash.
