How to Dispose of Toothpaste Tube
- 1Most toothpaste tubes consist of composite materials (plastic laminated with aluminum foil) and contain viscous chemical residues that make mechanical plastic recycling impossible.
- ✓The detachable plastic cap should be recycled in plastics, while the tube body must be discarded in standard municipal trash bags.
How to Dispose (5 Steps)
- 1
1. Detach and recycle the cap: The screw-on or flip-top cap is made of single-grade PP/PE plastic; rinse residue and drop into the plastic recycling bin.

2. Discard tube in general trash (Recommended): Standard squeeze tubes are aluminum-laminated composite plastics that contaminate recycling sorters; throw into standard volume-rate trash bags (Jongnyangje).

3. Cut and wash (Conditional plastic recycling): Only for monomaterial HDPE/PP marked tubes, cut the tube in half, scrub out all residual paste completely under running water, and recycle with rigid plastics.

4. Upcycling leftover paste tip: Cutting the spent tube exposes 3–5 brushings worth of paste, which acts as a fantastic mild abrasive cleaner for polishing sink faucets, water-spotted mirrors, and bathroom tiles.

5. Pump-style toothpaste dispensers: Contain internal metal springs and multi-resin pumps; if inseparable, discard the pump assembly in general trash and rinse the clear plastic bottle for plastic recycling.
Real-World Examples
Standard aluminum-laminated squeeze tubes: Detach plastic cap (plastic recycling) and discard body in standard trash bag
Eco-friendly monomaterial HDPE recyclable tubes: Cut in half, rinse paste thoroughly, and discard with rigid plastics
Standing pump-style toothpaste dispensers: Discard internal spring pump in general trash, rinse bottle for plastic recycling
Travel mini toothpaste tubes (20g–50g): Discard whole unit directly into volume-rate general trash bag
Frequently Asked Questions
Q. Why is a toothpaste tube labeled Plastic (OTHER) not recyclable in Korea?
A. Standard tubes use multilayer composite laminates combining polyethylene plastic with an ultra-thin barrier of aluminum foil to protect active ingredients. These composite polymers cannot be melted uniformly during recycling. The sticky paste residue also contaminates plastic flake washing lines, resulting in automated sorting rejection.
Q. Should I detach the toothpaste cap and recycle it separately?
A. Yes. Toothpaste caps (flip-tops and screw caps) are made of high-quality rigid PP or PE monomaterial plastic. Unscrew the cap, rinse out residual paste under tap water, and drop it into standard plastic recycling.
Q. How can I upcycle the leftover toothpaste after cutting the tube open?
A. Cutting open spent tubes reveals enough paste for 3–5 brushings. Apply this remaining paste to an old toothbrush or sponge to polish chrome faucets, scrub bathroom sink limescale, and eliminate tile grout discoloration using the natural mild abrasives (calcium carbonate/silica) in toothpaste.
