This project uses systems thinking and interdisciplinary integration approaches to develop a novel immersive educational simulation game and associated materials designed to highlight the role and importance of corn-water-ethanol-beef (CWEB) systems in supporting the ever increasing demands for food, energy, and water in the United States.
Every liter of ethanol produced generates about 5 L of stillage. The liquid portion (thin stillage) is rich in nutrients and sugars. The goal of the project is to remove the carbon dioxide generated from the fermentation scrubber while treating the thin stillage stream. CO2 will be used as a carbon source to promote a combined immobilized growth of algae and bacteria in the thin stillage. The treatment of thin stillage will result in the generation of biogas; either methane or hydrogen gas.
The overall goal of the experiments is to improve the quality of drinking water. This study will examine the removal of contamination related to agricultural practices from water; specifically nitrate and atrazine. These detrimental compounds are easily ingested through the use of fertilizers in agriculture and have been proven to cause negative effects to the human body.
