The U.S. discards 13 million tons of plastic annually — more than 12% of our overall waste — and barely 7% of the plastic we discard is recycled. The biggest proportion of that plastic waste comes in the form of plastic bottles (beverages as well as personal care products, cleansers and the like) and packaging. How about a plastic bottle greenhouse? Or a colorful outdoor wall? That’s what this sewage treatment plant in Scotland tried, to great effect:

I wish I had come across this idea years ago when I was more involved in schools and community art projects.
I have done a lot of strange things with recycling plastic drinks bottles, but why did I never think of building walls?
These were used to screen off a natural sewage treatment area for the Fife Earthship where plants were used , but I also saw a large greenhouse built with these.........which got me thinking...................
The trouble is I don't really drink fizzy pop to get the bottles!
