This company is utilizing plastics in a new creative building material. While their product has almost unlimited potential, they have been having a difficult time getting architects to invision the possibilities.

Also, in referencing back to EM 670 last quarter, I remembered a classmate noting how difficult and expensive is has been to get plastic, new and recycled, at his company. It seems like while the resultant product is innovative and eco-friendly, it seems it may have too many prohibitive factors to make it a staple in the construction industry.
