More Scrap Tires Reused

Americans get rid of almost 300 million scrap tires every year.
Historically, a lot of used tires have ended up at the bottom of
ravines or in huge tire piles. These piles have created eyesores,
toxic fire traps and places for mosquitoes to breed. But Ann Murray

Americans get rid of almost 300 million scrap tires every year.
Historically, a lot of used tires have ended up at the bottom of
ravines or in huge tire piles. These piles have created eyesores,
toxic fire traps and places for mosquitoes to breed. But Ann Murray
reports that the days of widespread illegal dumping and monster tire
piles are waning:


Michelle Dunn is making her way through shoulder high knotweed to
show me an urban tire dump:


“This is the start of the tires. They’re all entwined in here.”


About 300 tires have been chucked over the hill in this quiet
Pittsburgh neighborhood. Dunn’s with a non-profit that helps
communities clean up old dump sites. She says illegal tire dumping is
still a problem but not the gargantuan problem it used to be:


“I don’t think you’re seeing new major piles appearing. The regular
Joe isn’t dumping as many tires because people are now becoming
educated. They have a service they can take their tires to have them
disposed of properly.”


In many states, the place to take old tires is now the neighborhood
tire store. Since the early 1990s, about 35 states have required tire
dealers to collect small fees to dispose of used tires. Now fewer
people dump tires and about 4 out of 5 scrap tires have been
cleaned up. Numbers have nosedived from a billion stockpiled tires to
less than 200 million.


Not all states have had equal success reducing their cache of old
tires. Some states such as Alaska, Wyoming and Nevada are still
struggling. Their rural landscapes have made it hard to catch illegal
dumpers and collect tires. Many other states have stepped up
enforcement. They now make dumpers pay to clean up waste tire
sites and register scrap tire haulers. But Matt Hale says new laws
aren’t the only reason scrap tire programs are working. Hale directs
the division of solid waste for the US Environmental Protection
Agency:


“In many cases a successful program is the result of being near
markets for tires. In the southeast for example, tires are in demand as
a fuel use and that certainly makes state tire programs in that part of
the country easier.”


Stricter waste tire laws have made it easier for the tire
recycling industry to take hold. Dave Quarterson is a senior director
with Liberty Tire. Liberty’s the biggest tire recycling company in the
country:


“It has been difficult for companies like ours in the past to look at
having to invest 5 or 10 million dollars into a facility to recycle tires
and then to have to compete on the street with a guy with a $1000
pickup truck who’s rolling ’em down an embankment somewhere.”


In 1990, very few of the 300 million scrap tires generated each year
were re-used. Today about 90 percent are recycled. A majority of
these tires are chipped and shipped to cement kilns and paper mills
to be burned for fuel. A fuel source that US EPA says is relatively
safer than burning coal but environmental groups say is still polluting.


Tire recyclers like Liberty Tire are now in big demand. Liberty uses
almost 75 million scrap tires a year. Their headquarters
plant specializes in making “crumb” rubber. Crumb’s used in
everything from football field turf to brake lining. It’s made from
shredded tires that are frozen with liquid nitrogen and then pulverized
into various sized bits.


Dave Quarterson, says tire recyclers are starting to move away from
producing tire chips for fuel to making newer products like crumb
rubber:


“We’ve got a lot more money into producing it but it’s a lot more
rewarding financially.”


States are also encouraging new uses for the decades old tires that
still remain in big, abandoned piles. Even with this backlog of old
scrap tires, states and recyclers are optimistic that growing markets
and new laws mean more and more scrap tires will have a useful
second life.

Epa Proposing New Rules for Sewage Plants

The U.S. Environmental Protection Agency is proposing new rules on how sewage treatment plants clean water after heavy storms. The Great Lakes Radio Consortium’s Shawn Allee reports:

The US Environmental Protection Agency is proposing new rules on
how sewage treatment plants clean water after heavy storms. The Great
Lakes Radio Consortium’s Shawn Allee reports:


When rainstorms overwhelm sewage treatment plants, cities sometimes
blend raw sewage with clean water that can contaminate local rivers and
lakes with bacteria. To stop this, the EPA’s proposing a compromise
with local governments. Cities may blend waste when there’s no
alternative, but they must improve their waste treatment systems.


Alexandra Dapolito Dunn represents an alliance of city treatment
facilities. She says local governments need this flexibility.


“There are going to be some communities around the country where, due
to the low income and the distressed nature of an urban population, they
may have a difficult time affording the most cutting edge technologies
available.”


It’s not clear how much money cities will save under the proposed
guidelines. Upgrades can cost millions of dollars, and right now,
treatment centers compete for limited federal assistance.
