This is such a great idea and it is just the tip of the iceberg with regards to innovative ways of reusing the materials and waste that are all around us. 

For example, a couple of years ago some councils in the UK debuted poo powered buses and Adidas have just released their first trainer made out of plastic waste extracted from the oceans. 

These initiatives give us all hope for the future and what is possible when there is a conscious effort (and money put behind it...) to create and develop new products through non-harmful means.
