When your Zero Waste Box™ is full, simply tape the top opening shut. Your box will arrive with a prepaid return shipping label already attached on the back.
All you have to do is either call UPS on 03457 877 877 and provide them with the tracking number from the label or schedule the collection on the UPS website.
The tracking number starts with the number 1, followed by the letter Z: "1Z".
Add the tracking number without any spaces.
