You can recycle Kirkland water bottles, but you'll need to return them to a warehouse store location or the customer service desk at your local Costco warehouse store.
You can also recycle them in any participating recycling center, but that's not always an option. To find out if your local recycling center accepts Kirkland water bottles, visit their website.
When you recycle Kirkland water bottles, they'll be turned into something called "water bottles." These bottles are then used to refill the bottles of water sold at Costco. This helps to reduce the amount of plastic in landfills.
