After reading this and many replies that have come along with it I wonder about plastic soda bottles using them as a filler in the wall. I kinda sketched some ideas down but one idea was to fill the bottles with water and then when the wall was set up take a nail and poke them from the lower end before the wall completely dried. This would allow the water to drain out and then you have a large void in your wall that would act as an insulator. I actually got the idea from watching transformers when Sam and Makala hid in the adobe house in the desert. One of the walls in the house seemed to be built out of plastic bottles and adobe. Just a thought not sure that was what you were looking for though.

There doesnt seem to be much bonding between the papercrete and glass though, so tensile strength remains poor. It also reduced shrink during drying.
