Center for Crops Utilization Research
In the 1980s a crisis existed in American farming—a crisis of overproduction, underutilization, and decreasing international market share for raw commodities. Also, the United States’ growing dependence on imported oil and long-term forecasts for increasing oil prices put America at risk. To address this crisis, Center for Crops Utilization Research (CCUR) was established in 1984 through a special appropriation from the Iowa legislature. The center was tasked to respond to the urgent need to improve America’s agricultural competitiveness. Four decades later, there are new opportunities to increase demand for Iowa’s crops. Consumer demand is increasing for new healthful food ingredients, biobased alternatives to petroleum-based products, and sustainable and environmentally friendly industrial processes. The rapid advancement of new food processing technologies and industrial biotechnology enable those demands to be met in an economically viable way. While CCUR’s core mission of increasing demand for Iowa crops remains relevant, the center is also taking these opportunities to grow our connection with companies and entrepreneurs to help them to test, troubleshoot, and optimize their ideas in an industrial-friendly setting.
Organizational Unit
Agricultural and Biosystems Engineering

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

The worldwide decline and overexploitation of ocean fisheries stocks had provided an incentive for the rapid growth of aquaculture. The aquaculture industry has been recognized as the fastest-growing food production system globally, with a 10% increase in production per year and is one of the most reliable and sustainable growth markets for manufactured feeds. Extrusion technology has been extensively used in the modern aquatic feed manufacturing, due to nutritional, physical properties improvements and cost effectiveness of feeds. Cost related to aquatic feed remains the biggest challenge, especially for small-scale producers. In order to understand costs and potential breakeven points, a single screw extruder and three different production scenarios (0.2, 2 and 20 t/day) throughput were used to develop techno-economic models for small-scale producers of extruded aquatic feeds. The results show annualized capital costs decreased as production capacity increased. Thus, aquatic feed producers could use this tool to evaluate annual costs and benefits to determine processing economics. Producers will have to consider the ingredients used, though, as raw ingredients constitute the greatest cost for the production of feeds.
