Recycled tires, long considered a landfill pest, may actually
be a blessing in disguise for some landfill operators. Across
the country, old tires are being processed into chips and
used in leachate collection systems as an alternative to
gravel or sand.
Used tires present many benefits in landfill construction,
including:

and pricing.
Ease of leachate flow. Recycled tires have larger pore
spaces than gravel or sand and do not have fine minerals
that restrict flow through the collection system and prevent
complete removal of landfill liquids.
Ease of transportation. The light-weight
tire chips are easier to transport and maneuver than gravel
or sand. One cubic yard of tire chips weighs approximately
900 pounds; a cubic yard of gravel weighs more than 3,000
pounds.
Readily available supply.
Durability. The tire chips are expected to last the life
of the landfill.
Cost-effectiveness.
As
a lightweight fill alternative on foundations, tire shreds
are used instead of conventional soils. Tire shreds are very
resilient and aid in absorbing pressure from the surrounding
earth, reducing the pressure exerted on the wall. When used
around foundations, it also provides for better drainage,
lower humidity, and a dryer wall. This provides for reduced
cracking and damage due to the earth pressures.
