The production of corn-based ethanol in the U.S. is dramatically increasing, and consequently so is the amount of byproduct materials generated from this processing sector. These coproduct streams are currently solely utilized as livestock feed, which is a route that provides ethanol processors with a substantial revenue source and significantly increases the profitability of the production process. With the construction and operation of many new plants in recent years, these residuals do, however, have much potential for value-added processing and utilization in other sectors as well. This option holds promise of economic benefit for corn processors, especially if the livestock …


Renewable Energy Alternatives: Current Status And Capacities, Kurt A. Rosentrater, Youakim Al-Kalaani Apr 2005

Renewable Energy Alternatives: Current Status And Capacities, Kurt A. Rosentrater, Youakim Al-Kalaani

Kurt A. Rosentrater

A key to the United States’ economic growth is an ever-increasing demand for energy, which has traditionally been met primarily by combusting the hydrocarbons found in fossil fuels. As environmental concerns grow, renewable energy resources are gaining increasing attention. To aid both researchers as well as educators, this paper examines historical energy data for both traditional as well as alternative energy sources. Even with the progressive developments of non-traditional energy sources over the years, the U.S. still receives more than 90% of its energy from fossil and nuclear fuels. Explicit examination of the alternative energy sector has revealed that hydroelectric …
