Although the TGER did not perform to its full potential during the 90 day assess-
ment and validation, it did demonstrate its ability to convert waste to energy and
reduce diesel fuel consumption in a harsh operating environment. Below is the
system level parameters recorded during live testing in Iraq. Due to equipment
problems, the TGER was not able to demonstrate its ethanol production capabilities
and provide enough data to statistically evaluate the bioreactor performance. The
harsher conditions in Iraq also required more maintenance time for the pelletizer,
thus reducing their pellet production capabilities. These issues and others con-
tributed to the reduced fuel efficiency of the TGER while in operation in Iraq.
