        　　American scientists are developing a new use for chicken fat. Scientists at
the University of Georgia in Athens are burning fat from chickens and other
animals to produce heat. They have successfully used the fat to produce hot
water and heat for buildings at the university. The scientists say their tests
show that animal fat often is less costly than more traditional fuels. They also
say that burning the fat is safe for people and the environment. They add that
no one has reported smelling anything unusual from the local heat production
center. Scientists with the University’s Department of Biological and
Agricultural Engineering have been supervising the tests. They have burned
different mixes of fuel and animal fat. The result of the tests shows that the
animal fat produces about ninety percent of the heat that traditional fuel oils
produce，and substances released into the air by the burning fat are low in
harmful pollutants. According to Engineer Bob Synk，another member of the
research team，an increasing number of Americans believe that the country’s
dependence on foreign oil imports is a problem. The government’s energy plan
calls for non-traditional fuels to supply up to twenty percent of America’s
energy needs within twenty years. The United States already produces almost
five-thousand-million kilograms of fat from chickens，cows and pigs each year.
The scientists predict that chicken fat and other natural products could become
important fuels in the future.
