Here at Little Sisto we are committed to reducing our environmental footprint. We’ve noticed over the years that even though we may have the best intentions we don’t always get it right. It’s too easy to forget your keeper cup so we went out and found another solution. Introducing our new partnership with RTRNA Cup. We believe this system is a sustainable and practical way to save disposable coffee cups heading to landfill. Here’s how it works:

STEP ONE: Instead of accepting a disposable cup, choose a RTRNA Cup for a small deposit ($3 Cup $2 Lid).

STEP TWO: Consume your coffee with guilt-free zero waste enjoyment

STEP THREE: Bring back your RTRNA Cup and exchange it for another one or we will refund your deposit


If you forget to bring your cup back, no dramas, you can just put a deposit down on a new RTRNA cup. Bring them both back the following day and your deposits will be refunded.  That’s what makes this system so clever. And so user-friendly.

 Little Sisto is  proud to be a part of the RTRNA Cup network. That means you are also welcome to return your cup to one of the other responsible cafes in the network. Check the RTRNA Cup website for details.
