My kid's birthday party was today. Yes, reuse takes a little more time than take-make-dispose, but it is worth it. These 34 cups are on their 6th birthday with us, so they represent 204 cups not wasted, but some of these cups are 40+ years old, seeing 100s of uses. That's a lot of waste avoided.

How sustainable design should work. Making something that does everything a new product does, while using as few new materials as possible. This Bluetooth Speaker uses a worn out guitar as its acoustic chamber and installs into the guitar. Maximum function and sustainability, minimum waste.
