Environmental protecting by Wal-Mart

The American retail giant said that it will test two new types of hybrid trucks and two types of trucks powered by alternative fuels to make its trucking fleet more efficient and environment friendly.

 Wal-Mart has one of the largest private trucking fleets in the world,
and vowed in 2005 to make its trucking fleet 25 percent more
efficient by the end of 2008. It said the latest tests are an effort
to double its fleet efficiency by 2015, from its 2005 baseline.

As part of
the pilot program, Wal-Mart said 15 trucks operating in one of its
distribution centers near Phoenix will be converted to run on
Reclaimed Grease Fuel made with the cooking grease from its stores.

At a
distribution center in Southern California, Wal-Mart said it will
test Peterbilt trucks that operate on liquid natural gas.

Wal-Mart is also testing a diesel-electric hybrid truck developed by
ArvinMeritor, and a Peterbilt heavy duty hybrid truck that uses a
diesel-electric hybrid power system developed by Eaton Corp and Paccar Inc.
