This Soap Bottle Is Made of Soap and Also Dispenses Soap Image: Project Soapbottle I’m always trying to reduce the amount of plastic I throw away, and this new Kickstarter project’s clever solution, which uses soap to create a multi-purpose, zero-waste container, has me intrigued. Advertisement Project Soapbottle, which was initially conceived by Jonna Breitenhuber as part of a student design contest, is a new line of packaging that uses solid soap to create a natural and biodegradable container for holding the liquid soap inside. The end result is simple: Once you run out of liquid soap, you can simply use the container just like you would a traditional bar of solid soap, eventually washing away any trace of the packaging along with any unwanted dirt and grime.
