In a few months will begin to Northwestern University, Missouri, burning animal dung pellets odorless in the electric power station affiliate, becoming the latest source of energy for the University, which was famous in the use of alternative fuels.
According to the Center for Energy Department of Natural Resources of the state, the university is the largest institution of bioenergy use in Missouri, may be the only institution that used this combination of alternative fuels in the United States.
I have been Marivel University in Missouri in the far north of the burning of sawdust and paper – with small amounts of natural gas and oil – to produce steam for heating and cooling facilities on campus. The burning of animal dung, which has been under test for three years, a logical choice for the University is surrounded by farm animals the center of an agricultural area and wide. But that even large farms in the region is considering how to apply this technology as a way to get rid of waste animals.
Says Nancy Baxter, an expert at the university that the university was looking for a new fuel when the animals appeared to waste the next logical step. This waste contains a lot of energy and become odorless when separating solids from liquid.
Come attempt by the Northwestern University in the midst of rising prices of heating oil and fossil fuels (coal, oil) traditional, reminiscent of the oil crisis in the seventies when tight supplies and increased prices.
Said John Redden Director Electricity lab, the university will provide about half a million dollars a year on the basis of energy prices, the current burn a combination of the three types of alternative fuel with small amounts of oil and gas, and will match the amounts spent on the project within five to seven years.
Said Sam Orr planned energy center in the Department of Natural Resources that Northwestern University has worked hard and perseverance to become a leader in this area, all in order to save on expenses.
But the university says that the economy in expenditure is not the only reason, but that need was the motivation to study alternatives to natural gas and oil.
During the bitter winter in the very late seventies stopped one of the public companies for supplies of natural gas to the university. With the decline in temperatures below zero, the university was forced to wait until the arrival of a tanker truck loaded with oil from the state of Tennessee to unload enough two weeks of heating oil. Hence the University has decided to search for another way.
Redden visited Chicago and New York to inspect the factories that burn municipal waste, but he abandoned the idea for fear of attracting rodents to the campus.
And then guided to a rich resource for fuel – sawdust from mills and timber companies destroying the buildings that were keen to get rid of their waste, and the university began boilers burn sawdust in the early eighties. Today, a timber waste and seven companies build about 75 percent of the fuel mixture and the university.
In 1994, residents protested to neighboring villages to Marivel plans for the establishment of new farms in the region for fear of exacerbating the problem of odor emitted from the existing farms, and here was born the idea of research for alternative fuels and new.
The University has established a laboratory for processing animal waste and mixing with dry materials such as straw, paper, straw and rye bran.
According to U.S. Department of Energy that the use of organic waste, an alternative energy source is relatively small, but that could change if continued global warming and the price of traditional fuel.
It is said that this biofuel contains no sulfur or broadcast gases contribute to heating the earth when they are burnt. Perhaps the biggest attractions of the process as an alternative fuel is provided in abundance.
