It's not like the Big Dig tunnel in Boston is a green project, but one civil engineer who worked on the Big Dig for ten years was able to reuse some of the waste materials to build his new home. Paul Pedini told
it should be more common for these top-shelf materials to be recycled "into a public housing project, a municipal parking garage, a prison, even a replacement bridge". It isn't necessarily cheap to reuse materials (Pedini's house cost $645,000), but it was an efficient use of materials, said the house's architect John Hong. The waste materials were free for Pedini, and saved Pedini's contracting company about $20,000 in demolition and dumping fees.
