PET bottles Recycled into Textile Yarn

I know this site is supposed to be about my ideas but if someone has a better idea than me than why not talk about them. I have a friend lets call her 'Kiss' she works in a company who strip down PET bottles , you know like colas and other beverages and make them into yarn to be used by the textile industry.

I might get a chance to visit this plant next month and know more about this. The reason i like this so much is that they are not doing this because they care about the environment, who knows maybe they do, they are doing this because it makes economic sense.

This what everyone who wants to save the environment must understand that it is very difficult to make people care about the environment but much more simpler for them to care about making profits. More on this theory, lets call it "Economics of saving the earth" a little later.
