Clark County School District
How do Las Vegas casinos and some of the country’s
largest hotels benefit the Clark County School District?
(This is not a trick question.) These establishments produce
vast quantities of waste grease—about 6 gallons
per resident per year—which is used to make biodiesel
(B20) for the district’s school bus fleet. Of its 1,186 fullsize
school buses, about 1,100 run on B20 (roughly 86
buses in outlying areas still run on diesel because B20 is
not readily available). Haycock Petroleum and Biodiesel
Industries supply B20 to the district.
The district has demonstrated extraordinary leadership
in implementing this alternative fuel in its fleet.
It consumed 1,587,818 gallons of B20 in 2002, and will
consume about 3 million gallons in 2003. The district
converted 1 bus yard at a time to biodiesel, and learned
some important lessons. For example, the tanks need to
be well cleaned before the switch to prevent bacteria,
and the consistency of the fuel should be maintained as
closely as possible.
The school district has a large fleet of diesel maintenance
trucks that now run on B20. The water district
and city fleets are also looking at the school district as
an example, and the Nellis Air Force Base is considering
the possibility of testing B20 in some of its equipment.
