Tire
Recycling
Tire
recycling is the process of taking used tires that are no
longer safe for the road and making something else from
it. Tires are produced to be durable and they take up a
large amount of space which is a few reasons why most landfills
will not accept
tires.
There is also
the trouble of methane when the tires begin to decompose
presenting new problems which has resulted in new
solutions.
Tire
recycling is not new; however, there have been some recent
technologies that are reforming the way tires are recycled and
the uses they offer.
The
United States stock pile of used tires has greatly declined
since 1994 when the stock pile was about 750 million waste
tires.
In
2004 the stock pile of waste tires in the United States is
about 275 million. This decline is primarily due to the
state scrap management
programs.
Stockpiled waste tires presents environmental
and health risks including tire fires that can burn for months
at a time and creates considerable pollution to the air and
ground water.
Stock
piles of waste tires attract vermin and disease carrying
mosquitoes and some of the stock piles were being built in
ravines, woods and empty lots by illegal
dumping.
There are tire
recycling facilities located around the world that offer
several types of recycling
methods.
The
types of recycling usually consist of one of three methods;
mechanical grinding or shredding, cryogenically freezing and
crushing and an ultrasound treatment as well as a microwave
treatment which is being
researched.
The chain of tire recycling
includes the collection and sorting, production of alternate
products that can be sold and whole tire uses such as barriers
for erosion control and sound
barriers.
There
are a lot of innovated uses being found for discarded tires and
the days of huge piles of old tires laying around for years
growing higher and being a cause for concern are growing fewer
as theses technologies are
developed.
A
growing use of recycled tires is in the form of waste to
energy. This makes use of the scrap tire to provide
energy for large cement kilns as well as in the pulp and paper
industries.
Businesses are even exploring using scrap tires as a fuel
source. Whole tires are often chained together to
provide a barrier in car racing and the concept of
chaining tires together is being explored
inproviding
artificial reefs.
One
innovative use for recycled tires can be found in many
playgrounds as a surface for
play.
Some
areas use crumbled tires in the playground in loose form to
provide a soft surface making the playground a safer area to
play for the
children.
Other
playgrounds use the crumbled tire that is then heated to fuse
the crumbs together forming a thick, soft and solid play
surface.
Using
recycled tires in the playgrounds is a very good use of the
tires as well as providing safety and comfort on the
playground.
Other
playground surfaces such as sand, dirt and pebbles do not
provide as soft and giving of a surface as the recycled tire
surface and it is durable as
well.
Other
very creative uses for recycled tires include floor mats and
welcome mats for the home or business, shoes, swings for
children, messenger bags and even
jewelry.
As
people explore green technologies and ways to recycle and
create new products from our discarded items the possibilities
are endless.
