I just found a site that has a lot of interesting reading on it. If you are interested, check out www.wecansolveit.org .
Also there is a clothing site that uses recycled Coke bottles! Now the article I read had the wrong website address, and then when I found the right one, it is under reconstruction. But it sounds like it will be interesting to look at once it is up and running: www.resolvebrand.net
