CHICAGO–(ENEWSPF)–August 12, 2011. Governor Pat Quinn today signed legislation that continues his commitment to making state government greener and more efficient. The new law allows the Illinois Department of Transportation (IDOT) to begin using asphalt made from recycled roofing shingles. It also allows businesses to increase the amount of shingles used in asphalt production and requires IDOT to maximize the use of recycled materials in construction projects, saving the state more than $8 million annually.
