Road Worthy – Construction & Demolition Recycling

Recyclers and some paving contractors are eager to recycle asphalt shingles, but finish markets could use a boost from a more healthy economy.

Since Construction & Demolition Recycling last published the list of asphalt shingle recyclers this year, some of the listed companies have backed away from the business or, unfortunately, are no longer in business at all.

However , other companies have spent the past 2 yrs solidifying or expanding their shingle processing operations and also have watched as new competitors have arrived on the scene in their geographic regions.

Evaluations between the accompanying list of asphalt shingle recyclers and the one that was published in 2011 reveal that some of the titles have changed and the total number of shingle recycling locations has dropped in two years.

A few of the rising and falling fortunes of shingle recyclers vary by state and region, and some also are associated with wider overall economic trends.

Local Rifts

Bill Turley, executive director of the Construction and Demolition Recycling Organization (CDRA), Aurora, Ill., says assets in shingle processing can still vary greatly from state to state.

“We have seen places in the country where shingle recyclers have done well but other people where activity has tapered away from, ” says Turley, who was getting yourself ready for CDRA’s Asphalt Shingle Recycling Forum in Denver in early November 2013.

The single largest state in the U. S., California, is a long way from having the largest roster of shingle recyclers on the 2013 list. However , Turley says he believes the Golden State may soon see an increase in asphalt shingle recycling. “California is just beginning to get a little more active, and the state is developing a spec [to use processed shingles in roadway applications]. I expect to see shingle processing do better there in the future, ” Turley comments.

The existence of a recycled asphalt shingles (RAS) standards can help build momentum for the use of prepared asphalt shingles by paving companies and the highway and streets sections who are reviewing project bids.

While shingle recycling seems to have room to grow in California, in some other regions of the United States, processing capacity may have exceeded end-market need.

A spokeswoman at one recycling company in Missouri that appeared on the 2011 Asphalt Shingle Recyclers list says the girl company no longer accepts shingles meant for processing. “We have a good sized amass and no one to sell them to, ” she remarks.

“I’ve heard of places not taking a lot more shingles in because they are full up, ” agrees Turley. “It ebbs and flows. ”

One of the hurdles asphalt shingle cpus are facing involves competing along with recycled asphalt pavement (RAP) as feedstock in asphalt hot-mix plant life, Turley says.

“There are large piles of HIP HOP around the country, ” says Turley. He adds that contractors “have to get rid of that material, especially when it really is generated on government projects. ”

Thus, a introducing contractor may remove and “mill up 100 percent of an old region roadway or state highway, but often the contractor only uses ten to 20 percent on web site, ” says Turley.

Establishing specifications for RAS will remain a CDRA priority, according to Turley, who notes that the association keeps an information clearinghouse for advocates plus champions of shingle recycling at its www.shinglerecycling.org website.

The website lists the following states as allowing up to 5 percent manufacturers’ scrap RAS to be used:

  • Florida;
  • Georgia;
  • Indiana;
  • Maryland;
  • Michigan;
  • New Jersey;
  • North Carolina; and
  • Pennsylvania.

Also, Ohio Department of Transportation (DOT) specifications allow for up to a “certain percentage of recycled materials. ” As well, Turley says the CDRA is promoting the use of RAS in highway base courses in order to expand the end market for prepared shingles.

Nailing It

In most of the claims where RAS has gained approval, state DOTs and paving companies alike are more willing to use manufacturers’ shingle scrap rather than tear-off shingles. The primary fear with tear-off shingles continues to be the existence of roofing nails within the tear-off stream.


A Central Area

For nearly a decade, the Building & Demolition Recycling Association (CDRA) has maintained the www.shinglerecycling.org website as a resource for those wanting to know more about the state of the recycled asphalt shingles (RAS) sector.

The website also includes a database of shingle recyclers and cpus (searchable by state) as well as home elevators state department of transportation connections and links to applicable research reports.

The website’s Environmental Regulations section also offers links to state regulatory connections as well as a case study of how Commercial Recycling where possible Systems of Scarborough, Maine, caused state agencies to promote asphalt shingle recycling.

Summaries of research projects in two states, Minnesota and Missouri, are also hosted on the site. Each of these studies regarded as the viability of using tear-off shingles in recycling applications.

The particular CDRA’s Turley says responsible scrap shingle processors can overcome this perceived quality problem with one essential step. “That’s why God produced magnets, ” he quips regarding the removal of nails from the tear-off shingle stream.

“The great recyclers have learned how to clean up their material to the point where it satisfies the specification, ” Turley proceeds. “We really don’t see a problem with nail contamination. ”

More so than the processing limitations, Turley and the CDRA are concerned about “sham recyclers” who charge a tipping fee to collect asphalt shingles meant for recycling but then either fail to process the materials or begin to process them but never cultivate finish markets. In either case, the full recycling cycle is never closed, and an environmental hazard is created in the form of a stockpile.

One recent example of this occurred near Knoxville, Tenn., where in 2011 a company known as Greenphalt Recycling set up shop to accept scrapped shingles.

According to the website of Knoxville TV station WBIR, www.wbir.com, the owners of that corporation “skipped town with thousands of dollars in [tip] fees plus left a big mess behind. ”

Subsequently, the city of Knoxville has contracted with Tag Hinton, owner of River Road Shingle Recycling, Louisville, Ky., to deliver in a crew to process the stockpile and market the resulting materials.

Hinton estimated some 28, 000 cubic back yards of shingles were abandoned at the site; but , according to WBIR, they have committed to grind through the entire amount plus clear the site by the end of 2013. “By the end of this year, the website will be level and clear as if nothing was here, ” this individual told the TV station.

Once the stockpile is clear, Hinton says he plans to maintain a existence in the Knoxville market as Knoxville Shingle Recycling, thus providing among the new company names appearing on the 2013 version of the Asphalt Shingle Recyclers list.

One Thought on “Road Worthy – Construction & Demolition Recycling

  1. Sounds like shingles to me. See your doc to get some treatment for it and get some tagamet at the store to help too. My girlfriend had shingles on her buttocks almost two years ago and now has them in the peri area so they can easily be shingles but get them checked by the doc and get some medicine to help shorten the duration of them etc. It was also suggested that she try either water based or silicone lube as this might have contributed to the problem.
