Evaluating the Sustainability of an Advanced Biofuel Using Attributional and Consequential Life Cycle Assessments

Creator:: McDaniel, Allexander M.
Abstract:: Attributional and consequential life cycle assessments are useful in evaluating the environmental impacts of a process, product, or decision. Both types of life cycle assessments differ however in their scope and their ability to answer specific questions. In order to fully understand and compare the environmental impacts of a sugarcane...

Downstream processing of microalgal biomass for biofuels

Creator:: Sander, Kyle B.
Abstract:: This thesis documents the work carried out investigating the downstream processing of algal biomass for biofuel production. A life cycle assessment was conducted on a hypothetical algal biodiesel process in which it was found drum drying and cell component separation were life cycle intensive processes. A laboratory experiment was conducted...

A modeling and experimental approach to understanding the bottlenecks in xylulose utilization in S. cerevisiae

Creator:: Hohenschuh, William
Abstract:: The production of fuel ethanol from lignocellulosic biomass has the potential to replace a significant portion of non-renewable transport fuels. Woody feedstocks are composed of cellulose, hemicellulose, and lignin. Glucose, the monomer of cellulose, is readily utilized by wild-type S. cerevisiae, but xylose, which comprises 60% of the sugar in...

Hemicellulose utilization by yeast for ethanol production- adaptation, effect of inhibitors and a flux balance based analysis

Creator:: Avanasi Narasimhan, Ragothaman
Abstract:: A major challenge in ethanol production using lignocellulosic feed stock is inefficient utilization of hemicellulose, which accounts for 30-40% of lignocellulosic biomass. Xylose, comprising >60% of recoverable sugars from hemicellulose is a major product of the hemicellulose hydrolysis. Utilization of this carbon source would significantly increase the ethanol yield from...

Evaluation of feedstocks for cellulosic ethanol and bioproducts production in the Northwest

Creator:: Miller, Wesley C. (Wesley Clair)
Abstract:: Cellulosic ethanol production for transportation fuel is one source to help satisfy the increasing worldwide demand for energy and depletion of the fossil fuel supply. Evaluating potential production from plants and waste in Oregon, Washington and Idaho is the purpose of this study. Reed Canary grass, Annual Ryegrass, wheat straw,...

Development of a Statistical Emulator of US Crop Yields via a Deep Neural Network Approach

Creator:: Proctor, Kyle W.
Abstract:: Agricultural systems are inherently complex; understanding these systems requires knowledge of climatology, plant physiology, soil physics, economics, and the human psychology of the farmers themselves. Decision support tools strive to leverage existing data to help guide stakeholders towards the best policies and practices for their situation. Quantitative crop simulation models...

Quantifying the fertilizer value of algal meal : an evaluation of an integrated dairy-anaerobic digester-algae production facility

Creator:: Andrews, Shannon B.
Abstract:: Algae have shown great potential as a source for renewable fuels. However, current production schemes have not been able to prove a sustainable energy return on investment due in part to the high costs of nutrient addition and the energy required for drying the biomass. Integrated algae-dairy production systems have...

Metabolic engineering of Shewanella oneidensis MR-1 for microbial fuel cell application

Creator:: Hall, Robert G. (Robert George)
Abstract:: Shewanella oneidensis MR-1 is a gram-negative, facultative anaerobic bacteria with the capability of dissimilatory metal reduction. The ability of the organism to reduce a wide range of solid metal-oxides during anaerobic respiration makes it an ideal candidate for the powering of microbial fuel cells (MFCs), which capture the electrons discharged...

Using a membrane reactor for the sulfur-sulfur thermochemical water-splitting cycle

Creator:: Knapp, Nathan Michael
Abstract:: The hydrogen economy is a possible component of an energy future based on use of alternative and renewable energy sources, deemed desirable from the general consensus of the worldwide community that we do not want to further exacerbate the climate problems that we have introduced over the last two centuries...

Properties of hydrogels for immobilization of bacteria in a commercial microfluidic dioreactor

Creator:: Weymann, Davis
Abstract:: Current technological shortcomings limit the economic viability of capturing and utilizing small sources of methane. The development of a reactor to overcome these limitations would unlock economic opportunity and incentivize reduced methane emissions. A microfluidic bioreactor containing immobilized methanotrophs has the potential to overcome these limitations by profitably converting small...
