Auburn Hills, Mich. - DaimlerChrysler Corporation is
tapping waste gases from the decomposition of landfill trash to provide power for its two
St. Louis, Missouri, assembly plants.
The landfill gas
contains 50 percent methane, a renewable fuel source that otherwise goes to waste. Methane
is also a greenhouse gas, so the project will reduce use of fossil fuels and eliminate a
source of greenhouse gas emissions. To use the captured gases, DaimlerChrysler will
convert two of the four boilers in its St. Louis plant powerhouse.
"This is the
way to make environmental protection work," said James J. Lyijynen, Vice President -
Stationary Environmental and Energy for DaimlerChrysler. "We are reducing our
reliance on fossil fuels and cutting emissions from one of the primary sources of
greenhouse gases, at the same time we are reducing costs for the company and our
shareholders. That is sustainable environmental protection."
partners in the project are Superior Services of Onyx North America, which operates the
landfill about three miles northwest of the St. Louis assembly plants, 2 and Toro Energy
which will provide the equipment for trapping the waste gases at the landfill, treating
and compressing the gases, and piping them under low pressure to the plant powerhouse.
have demonstrated that landfill gas is a clean, reliable fuel source. In addition to
reducing greenhouse gas emissions, the capture and use of landfill gas improves local air
At the St. Louis
facility, two of the plants' four boilers were modified to use landfill gas in a way that
produces the same thermal characteristics as natural gas boilers. The boilers produce
steam that is used for process heating, especially in the paint shop, and for space
heating. In summer, the steam drives a turbine that powers three chillers for cooling.
The St. Louis
project is scheduled to go on line later this year. The St. Louis North plant assembles
the Dodge Ram pickup trucks; the St. Louis South plant assembles Dodge Caravan/Grand
Caravan, Chrysler Voyager/Grand Voyager and Town & Country minivans.
