The
big question was:
Is it possible to create a service with better on-time collection,
fewer problems for the resident, less pollution in the neighborhood,
reduced traffic, and do all this without charging more money per
month than the present haulers?
The big answer was:
Yes, Yes, Yes, Yes and Yes! It all hinged on creating a "new
generation" waste business from the ground up using the
best technologies and the best management practices …. Liberty was
ready to "do things right".
This could happen only if Liberty could solve 3 clear problems:
1) Garbage truck engines did not burn fuel efficiently,
2) Regular diesel fuel is dirty,
3) Garbage trucks are too heavy.
Here are the 4 solutions Liberty implemented:
First Garbage truck engines do not burn fuel efficiently
because the majority of them are old designs. The solution? Get rid
of the old trucks and run only trucks made in the model year 2005
and newer. These new turbocharged engines use 4 valves per cylinder
and employ advanced engine management systems to burn fuel more
efficiently, and to put fewer emissions into the air.
Second
Regular diesel fuel is dirty, so Liberty never burns regular diesel
fuel, but rather a new custom blended Bio-Fuel. Is this
experimental? No, the government has tested Bio-Fuels for years and
now has a new chemical standard for them, but people don’t use
these fuels much, because they cost much more than plain diesel
fuel, and because Bio-Fuel can clog up a truck older than 2005. The
new fuel will loosen all the sludgy deposits in older fuel tanks, in
the lines and injectors and then, clog the engines.
The only successful strategy is all new fuel and all new
trucks.
What is contained in this new Bio-Fuel? After research, Liberty
determined that by mixing high grade premium diesel fuel with
significant amounts of Soy oil, sometimes blended with cottonseed
oil, corn oil, and recycled cooking oil that the tailpipe emissions
in the neighborhood could be reduced dramatically.
Recycled cooking oil? That’s right! From time to time our
blend will contain amounts of purified cooking oil that was
previously used to cook French Fries or chicken. The Liberty blend
of Bio-Fuel is virtually the same as the formula selected by Harvard
University in February of 2004 as the new fuel for their campus
vehicles. We adjust our Bio-Fuel materials as pricing and
availability dictate. Our
goal is to eventually transition to recovered cooking oils as the
main component.
The Bio-Fuel that goes
into our Liberty trucks is renewable, sustainable, and comes from
America, not Saudi Arabia.
Third
Trucks are too heavy because they are constructed of bulky steel
that ends up adding too much truck weight everywhere they drive. The
solution came from Europe where overweight trucks could tear up
their centuries-old streets. An American company bought the rights
to produce a new-generation garbage packer in the United States that
uses HardOx ® Steel which is significantly harder than regular
steel but lighter at the same time. This company then built custom
garbage trucks for Liberty using these special steel formulas
and advanced structural designs for every new liberty truck that works in
Georgia.
The outcome? Lighter, stronger trucks that use less fuel, tires, and
cause less damage to your neighborhood streets.
The Final Result
Liberty’s clean-air efforts result
in a reduction of tailpipe emissions including: unburned
hydrocarbons, sulfate fraction, carbon dioxide, and airborne
compounds linked to cancer and asthma ... and that is your Liberty
"Clean Air Advantage".
