I made this carpet in a workshop with a school class. All materials used are recycled materials / trash, except for a few screws and some string. I make these sort of projects to inspire people to think of their trash as a resource. I suggest you team up with some people to make this, but it is possible to do on your own.
You can see a full tutorial for making the carpet on my youtube channel for additional information: www.youtube.com/user/ThomasDambo/videos
