This is the biggest point of discussion around this type of packaging.
The Problem: Traditional deodorant tubes are often made from multiple types of plastic (e.g., PP for the barrel, HDPE for the knob, sometimes a different plastic for the cap). This makes them difficult to recycle in most municipal recycling programs. Many end up in landfills.
Industry Solutions:
Recyclable Tubes: Brands are now designing tubes from a single type of plastic to make them easier to recycle. Look for the How2Recycle label on packaging.
Recycled Content: Many companies are using post-consumer recycled (PCR) plastic in their tubes.
Refillable Systems: Some brands (e.g., Dove, Old Spice, Secret) now offer a durable outer shell that you keep forever, and you only buy a refill cartridge that uses much less plastic.
Alternative Materials: Exploration into paper-based compostable tubes is ongoing, though overcoming moisture barriers is a challenge.
