Since 1905, the Department of Agricultural Engineering, now the Department of Agricultural and Biosystems Engineering (ABE), has been a leader in providing engineering solutions to agricultural problems in the United States and the world. The department’s original mission was to mechanize agriculture. That mission has evolved to encompass a global view of the entire food production system–the wise management of natural resources in the production, processing, storage, handling, and use of food fiber and other biological products.
History
In 1905 Agricultural Engineering was recognized as a subdivision of the Department of Agronomy, and in 1907 it was recognized as a unique department. It was renamed the Department of Agricultural and Biosystems Engineering in 1990. The department merged with the Department of Industrial Education and Technology in 2004.

Abstract
Fossil fuels are considered one of the most contributing for increasing the rate of greenhouse gas (GHG) emissions. On the other hand, renewable energy derived from biomass promising to reduce significantly the CO2 emissions, promoting less environmental impacts for the future generations. Nowadays, the cost and the environmental impacts of the process are the challenges for producing a green product with lower cost. Numerous research has been published over the lasts decades, but gaps remain in understanding the sustainability and the environmental impact of the ethanol production. The techno-economic analysis is designed in order to optimize one process, and the life cycle assessment is one tool for assessing the environmental performance of complex systems. The key objective of this study is to review and discuss the Life Cycle Assessment (LCA) and Techno-Economic Assessment (TEA) of cellulosic ethanol production that were done in previous studies.
