Description

Throughout the state, there are many sources of waste and recycled water from municipalities, power companies, and industries such as the semiconductor industry, feedlots and the dairy industry. In Arizona the dairy industry and feed lots are each $600 million industries. They produce waste water that contains sources of nitrogen and phosphorous that are ideal for growing microalgae. Integrating algae cultivation with these industrial waste streams would have the dual benefit of reducing ecological impact and producing valuable products. Arizona is an ideal place for an algal, agriculture, and industrial hub. The overall goal of this work is to build upon the leading expertise and research of the three Arizona universities to expand the algae industry within the state. Algae can serve as a feedstock for a variety of products ranging from omega 3 fatty acid supplements to animal feed to jet fuel and diesel. We are looking for ways to improve profitability of algae farming through optimization of production and improved processing of higher value products. Algae need water, carbon dioxide, nitrogen and phosphorus to grow. We plan to investigate a variety of nonpotable water sources and waste streams prevalent in our state and demonstrate that they can not only be used for algal cultivation but that algal processes can remediate these waters so that Arizonas water resources portfolio may be expanded and sustained. This project will employ postdoctoral, graduate and undergraduate students at the three universities. Students at all levels will be engaged in a highly relevant project that has the potential to attract in-state and out-of-state companies through development of new and critical methodologies and technologies that utilize an unexploited resource (waste streams) to meet the water and nutrient requirements for algaculture.
