Road paved with toilets gets green credential

If you take a stroll along a newly paved six-block stretch of downtown Bellingham, Wash., you’ll be excused if you think you put your foot in a toilet. The sidewalk contains 5 tons of crushed potty.

The project is the first to earn Greenroads certification, a rating system that aims to do for roadway construction what LEED did for the building industry – make projects more sustainable.
