No.  You can keep it or dispose of it properly.  If only the reservoir is being replaced, keep your current tube and bite valve to use with the new one.  You can also repurpose your old product as an ice pack by filling up half way with water and storing it in the freezer.  

If you have a warranty issue with a squeeze bottle we have a RePak recycling program at certain retail locations. Feel free to reach out to our team for more information.
