Why stainless steel and not glass?

We did a lot of research to answer this question for ourselves and chose stainless steel for a whole bunch of reasons. While milk in glass bottles is also a step towards a circular economy, stainless steel is far more durable, infinitely recyclable and protects your milk from light degradation. Our stainless steel is food grade 304 too, so completely safe for you.

What sort of milk is it?

It’s normal blue top milk - fresh, pasteurised, homogenised whole milk.

Why do I have to pay upfront for the bottle?

Fair question. Our goal (and a better way for our planet) is a circular bottle system. Paying a deposit on your first bottle encourages you to bring it back to store to be refilled. If there was no deposit, bottles would be far more likely to be thrown out.

Where do I take my return bottle?

Bring your empty bottle – ideally with the cap on – to a participating New World, just like your reusable shopping bags. Pick up a full Synlait Swappa Bottle and hand over your empties at checkout – you’ll only pay for the milk in your new bottle.

Can I return my bottle to another store?

Right now, our two New World partner stores are St Martins and Fendalton in Christchurch. Until we have more supermarkets offering Synlait Swappa Bottles, please return them to either of these.

Help, I forgot to bring my bottle back!

Happens to the best of us. You’ll need to buy a new full Synlait Swappa Bottle, and return it/them next time you shop. If you have a few at home, bring them in and you'll get the $10 you spent on them discounted off your next shop. Or even better... share one with a friend to help them join the circular bottle movement.

Do I need to return the lid?

Yes, please rinse the bottle at home and put the lid back on. We’ll remove it and make sure it’s recycled rather than ending up in landfill. If you forget, that’s ok. The important thing to return is the Synlait Swappa Bottle.

Is the lid recyclable?

Yes, but not in your kerbside recycling. Please return the lid on the bottle and we’ll make sure it gets recycled.

I have several Synlait Swappa Bottles at home, how do I get my money back?

If you have a few at home, bring them in and you'll get the $10 you spent on each bottle discounted off your next shop. Or even better... share one with a friend to help them join the circular bottle movement.

What’s the QR code on the bottom for?

Each QR code is unique and lets us and you trace the bottle. Scan the code to find out how many times it’s been filled and other unique information. As we’re in the early stages of this launch, most bottles will be new for the next few months until we get them moving around.

Do I need to keep the pink label?

The pink label is recyclable cardboard. Pop it in with your regular kerbside recycling.

Can I put the bottle in the kerbside recycling?

To make this programme work as part of a circular economy, it’s important that Synlait Swappa Bottles find their way home to Synlait, so we can rewash, sterilise and refill them. So please bring them back to one of our New World partner supermarkets.

Why is Synlait doing a phased launch?

Launching in stages will help us iron out any kinks in the supply chain and provide the best service, so we can make the experience seamless and easier for you to get involved.

When will more stores have them?

We aim to bring more stores on board across the country over the next few months. Sign up to our mailing list for updates on Synlait Swappa Bottle.
