So this example really does fit the bill. A brand that has taken junk that no longer had a purpose and created a completly new original and desired product. This company is striving off of 'sustainability' and in a good way... Or are they? They predominately sell bags made from sweet wrappers and newspapers.

This clever idea is the work of brothers Yair and Jonathan Marcoschamer and their mother Helen. When in 2004 they took a trip to Mexico and were inspired by the work of Mexican artisans who were creating handbags crafted from post-consumer waste. They have since saved over 150 million candy wrappers and other waste products from going to land-fill sites (Figure taken from website). Not only that, but they are making a living out of it. A bag retails at roughly $30, and the company has been shortlisted for the WGSN Global Fashion Awards in the Most Sustainable Brand or Retailer category.
