Plastic vs glass baby bottles: Which should I choose?

Yes, plastic baby bottles are recyclable. In Australia, Polypropylene (PP) is identified as plastic type 5, and items like baby bottles made from polypropylene can often be recycled if your local recycling service accepts plastic type 5.

However, not all local councils collect polypropylene for kerbside recycling, so it depends on your area. It’s always best to check with your local council to confirm whether polypropylene is accepted in your recycling bin.

Glass baby bottles are more robust than you might think. They’re made from borosilicate glass that's stronger than regular glass and so can withstand everyday use and are less prone to breaking compared to standard glass.  

However, they're still glass, so they may break if dropped on a hard surface. 

Borosilicate glass is a type of glass specially designed to handle heat, shocks, and everyday wear. Unlike regular glass, it’s made with boron trioxide, which means that it’s:  

• More heat-resistant and won’t crack with sudden temperature changes  
• Stronger, more durable and less likely to shatter if knocked or dropped  
• Chemical-resistant and won’t absorb smells, stains, or leach anything into liquids  

It’s used to make things like laboratory beakers, cookware, and increasingly, baby bottles. For parents, it means a bottle that stays crystal clear, handles repeated sterilising, and gives peace of mind with every feed.   

Borosilicate glass baby bottles are not typically accepted in standard kerbside recycling programs in Australia. This is because borosilicate glass has a different chemical composition and melting point compared to standard container glass, such as that used for beverage bottles and jars.  

Other disposal options 

• Check with local recycling facilities: Some specialised recycling centres may accept borosilicate glass. It's advisable to contact your local council or waste management facility to inquire about proper disposal methods. 
• Repurpose: If the bottle is still in good condition, consider repurposing it for other uses, such as storage for small items or as a decorative container. 
• Donation: Some charities or community groups may accept clean, usable baby bottles for reuse. 

Always ensure that any items donated or repurposed are thoroughly cleaned and safe for their intended use.
