"Product designer Jonna Breitenhuber has come up with an interesting way to get rid of plastic shampoo and body wash containers: by packaging the liquids in bottles made of slow-dissolving soap.
Soapbottle is a packaging made from soap. As the content within is being used, the soap packaging very gradually dissolves. When finished, remnants can be used again, as hand soap or processed into detergents. Soap is made of natural ingredients and is biodegradable: waste can be completely avoided."
