There's a company here in Illinois that makes lawn furniture out of recycled plastic. It's quite good, very durable, easy to clean and lasts forever. The company is By The Yard and I own some of their stuff. Very high quality! I think their idea is brilliant and I wish more companies innovated like they do.
I see crafts sometimes—small pocketbooks made out of stuff that would otherwise be thrown away, and the like—but no one has tried this on a large scale. It would be quite the conversation piece: “Our house is made of detergent bottles.” There was a house in Arizona next-door to my sister that was made from railroad ties. The guy had collected them as they were being thrown away. The walls were only half up.
But a corporation should try it.
