Actually, I've seen a lot of recycled objects in or on custom show cars and cruisers recently. I've seen things from a Viagra bottle for a coolant overflow, beer cans used to wrap ignition coils and other cylindrical parts, and orange traffic cones made from recycled 4L bottles. There is an artist that makes sculptures and things (trains, horse, airplane, fire engine) from parts taken from the junkyard! It's all skillfully welded, soldered, glued, and mounted to a hand-made wooden base made from a piece of a fallen tree. People do some very interesting and clever things with the recycled goods, besides throwing them in the trash. Or the Pacific ocean.
