I used to be on prime, but now just subscribe to items. If you subscribe to many items amazon usually does a really good job sending them out in a single box for any particular month.
Oh, I recycle them, but Prime encouraged me to make individual purchases of what were often tiny items. So, I knew I was using way more box than I ought.
Remember, recycling is not perfect. It takes energy, and unlike metals and glass, often the recycled material cannot be reused the same way. As a raw material, it has degraded in quality and utility.
