Benefits of Using Recycled Shingles

Reduces waste to landfills. Approximately 250,000 tons of shingles enter Colorado’s landfills every year. Shingles take decades to decompose, create caps in landfills allowing methane gas to develop, and don’t compact well.
Avoid Greenhouse Gas emissions. A life-cycle analysis of asphalt pavement (Environmental Road of the Future, COLAS group, September 2002) indicates 27,000 pounds of carbon dioxide are avoided on a typical paving project, by using 5 percent shingles in place of virgin asphalt binder.
Improved road performance. Studies and performance tests show that use of shingles in asphalt mixes helps reduce ruts and cracks.

Additional technical reports can be found on the national website at shinglerecycling.org managed by the Construction Materials Recycling Association.
