The Life Cycle of Our Glass Milk Bottles

Life Cycle Analysis of glass bottle

Is it better to buy milk in glass bottles? 

We’re a big believer that it is. But we also believe in transparency and letting people decide for themselves by providing the facts. So, we commissioned a scientific report.

How many times can a glass milk bottle be reused?

A glass milk bottle can be washed and reused around 25-30 times on average before recycling, depending on the number of times it’s returned. And glass can be recycled an infinite number of times.

What are the disadvantages of glass bottles? 

The disadvantage of glass is it weighs more, giving a higher carbon footprint for transportation. However, reusing the same bottle reduces the carbon footprint of production relative to single-use plastics. Milkround deliveries also cut down on petrol from shopping trips.

Why did we stop using glass bottles? 

The short answer is profit over the environment. And the decline of the traditional milkround around the turn of the millennium ushered in the rise of supermarket milk and juices packaged in cheap plastic cartons and tetra packs that have fueled our plastic waste crisis.  

How do you clean glass milk bottles?

Rinsing and returning our bottles for collection is easy. Just give them a quick swill in the sink and leave them out for your milkie to collect. We’ll then ensure they’re properly cleaned before being refilled, and reused again and again.
