Most toothpaste tubes are a laminate of plastic and a thin aluminum layer, fused so they can't be separated — which makes them not recyclable in curbside bins. They go in the black trash cart, unless you have a recyclable-tube brand or a take-back program.
📷 Scan an item with your phoneSome brands (Colgate and others) have switched to a single-material HDPE #2 tube that IS recyclable — it says so on the box. If yours is labeled recyclable, squeeze it empty, replace the cap, and put it in the blue cart. If it's not labeled, assume it's the mixed-material kind and trash it.
The screw cap is usually a recyclable plastic, but it's small — leave it on the tube.
TerraCycle has run oral-care recycling programs (often brand-sponsored) that accept any brand of tube, toothbrush, and floss container by mail — a good option if you want to divert them.
