Synlait Swappa Bottle

We’re all looking for sustainable, refillable, waste free ways to get our groceries, without going out of our way. We know you're doing your best so we're here to help. We're rethinking a staple in your weekly shop, with the Synlait Swappa Bottle.


Reusable stainless steel milk bottles

This safe, refillable, infinitely recyclable stainless steel bottle is filled to the brim with local milk farmed by a select group of farmers. We support them to run their farms with higher social and environmental standards - giving us fresh milk farmed better.

We’ve chosen stainless steel for our Synlait Swappa Bottles for a couple of good reasons. First, from farm to factory we store milk in stable, food-grade stainless steel. Because it’s easy to clean, sterilise and is light-proof it’s the perfect material for reusable milk bottles. Second, stainless steel is robust and long lasting, which means our Swappa Bottles can be reused repeatedly. And, when they do need to be replaced, they're 100 percent recyclable.

The Synlait Swappa Bottle is another step in our zero-waste journey – because, like you, we’re keen to reduce the amount of plastic we use. The Synlait Swappa Bottle – it’s your fresh way to buy milk.


An easy process: drink, return, repeat!

How you can play your part

We wanted to make the Synlait Swappa Bottle experience as seamless and easy as possible. We've partnered with select supermarkets to launch the Synlait Swappa Bottle. Here's how it works:

  1. Buy your full Synlait Swappa Bottle(s) from your supermarket chiller
  2. Enjoy fresh milk to the bottom of the bottle
  3. Rinse your empties and pop the caps back on, ready for your next shop
  4. Grab full ones from the chiller – hand in your empties at checkout, and you’ll only pay for the milk
  5. We sterilise and refill the bottles, and send them back to store
