Gray To Green - S1.E4

"Gray to Green" takes the notion of the three R's (reduce, reuse, recycle) to grand proportions by looking at Boston's "Big Dig" and the massive amount of waste created by the $15 billion public works project. Paul Pedini, a civil engineer on the project, had the idea to build his own home from the Big Dig waste. The success of this project sparked plans to create an office complex in Massachusetts from the same recycled material. These innovative projects serve as prototypes to demonstrate to city officials that there is value in recycling on such a grand level.
