Recycling of asphalt shingles
What good news to read that Hennepin County is now grinding up and utilizing used asphalt shingles to repave roads (Hennepin County recycles rooftops into road surfaces). California's Integrated Waste Management Board estimates that 11 million tons of asphalt shingles are disposed of annually within the United States. That's a heck of a lot of waste that is far better put to use on the roads rather than sitting indefinitely in landfills.
