There is an interesting movement happening at the moment around upcycling, especially reusing ocean plastics. The problem with upcycling is the fact that after plastics etc. are discarded, they begin to deteriorate. So, when you recycle them, they need to be sorted, cleaned and processed before you can do anything with them. This process is generally more expensive than making new materials.
However, as more and more big brands and celebrities get behind the movement, it quite excitingly looks like it's really gaining some traction.
