Join the Soda Club! Yes, you can make your own fizzy water at home and recycle the carbonators at Hill's Kitchen, Bed Bath & Beyond, and other stores. Just put in your zip code into their store locator. As is well known, bottled water is not safer than tap water, is a waste of money, and is bad for the environment. According to the US Recycling Institute, more than 80% of bottles in the US do not get recycled and end up in landfills. Also, millions of tons of greenhouse gas emissions are produced in the process of replacing the billions of bottles and cans not recycled. Make certain to ask the store which carbonators they recycle since there are different sizes. Say goodbye to bottled water!
Update: I just check with Leah at Hill's Kitchen. She said, "Yes! We do the exchanges on both sizes of canisters. Best item of the year! I love the machines!" It's so easy to join the Soda Club!
