Exploring the Anaerobic Co-digestion of Food Waste, Brewery Waste, and Fats, Oils, and Greases through Biomethane Potential Testing and Response Surface Methodology

Creator:: Liberman, Madalyn R.
Abstract:: Food waste (FW), brewery waste (BW), and fats, oils, and greases (FOG), are prevalent waste streams in municipalities across the country, particularly in the Pacific Northwest (PNW). Anaerobic digestion (AD), the microbial-mediated transformation of organic waste into methane-rich biogas, offers a sustainable, energy-generating, waste management solution for these wastes. Anaerobic...

Molded Fiber Bottle Coatings for Environmental Resistance and Sustainability

Creator:: Sim, Elaine
Abstract:: In recent years, non-renewable and non-biodegradable plastic packaging forms the majority of landfilled waste. These products, mainly made from Polyethylene Tetraphlatate (PET) and other polyolefins, have excellent durability and barrier properties, but take hundreds of years to degrade. Much focus has been put on developing environmentally friendly alternatives to polyolefins...

The Examination of Escherichia coli Contamination via Agricultural Water Applications and Survival During Pre-Harvest Field Curing of Dry Bulb Onions

Creator:: Racine, Jason R.
Abstract:: 2020 and 2021 brought the first reported outbreaks of salmonellosis epidemiologically linked to dry bulb onions in the United States. Outbreak investigations were not able to implicate a specific source of the contamination but speculated that contaminated water was a significant contributor. The Produce Safety Rule established minimum standards for...

Exploring the Ductility Minimum of Niobium C103 at Intermediate Temperatures using Triaxial Tensile Specimens

Creator:: Wood, Thomas N., II
Abstract:: This work explores the mechanical properties of single-phase niobium alloy C103 from room temperature to 600°C for the purpose of expanding safe uses of the material into new applications. The study utilizes a symmetrically notched triaxial tensile specimens to manipulate the internal stress field in order to observe the changes...

Operation of a High-Temperature Oxidation Reactor for Thermochemical Energy Storage

Creator:: Ramsey, Owen C.
Abstract:: The cost of long-duration energy storage poses one of the most significant limitations on the penetration of renewables into power grids. Thermochemical energy storage has great potential to reduce this cost through the use of a reversible redox reaction pair that has a high enthalpy of reaction. The chemical nature...

Evaluating Alternative Soil Amendments for Organic Northern Highbush Blueberry Cultivation in Sub-Optimal Soils

Creator:: Retano, Andrea
Abstract:: Escalating demand for organic blueberries has driven a significant expansion of northern highbush blueberry (NHB; Vaccinium corymbosum L.) production area. This expansion is particularly pronounced in regions of the Pacific Northwest where native soil conditions are sub-optimal for NHB, notably east of the Cascade Mountain Range of Oregon and Washington,...

Assisted Migration in the Colorado Subalpine Forest

Creator:: Najim, Tara
Abstract:: This capstone study reports on global warming-induced changes to the Colorado subalpine zone climate and disturbance regimes. It assesses the impacts of these changes upon the dominant subalpine tree species and summarizes future species distribution modeling for these and other nearby species potentially suitable for the future subalpine zone in...

Comparison of total dose to individuals from temperate and arid environments

Creator:: Elmore, Brockway F., II
Abstract:: This paper analyzes the decision-making process utilized in temperate environments for building nuclear facilities and whether it was going to be applicable to nuclear facilities built in arid environments. To answer this question, the total dose to individuals from arid and temperate environments were compared using RESRAD-OFFSITE and changing the...

Classification Modeling of Nuclear Power Plant Outage Severities with Complement Naïve Bayes and Bidirectional Encoder Representations from Transformers

Creator:: Castillo, Michael A.
Abstract:: Low-level nuclear power plant outages in the United States can lead to unanticipated costs, potentially compromising the expected operation lifetime of the plant. Nuclear power plants are complex systems of interfacing components and highly regulated processes. This inherent complexity makes predicting outages from system dependencies very challenging. When outages do...

Functional analysis to inform early design decisions for novel systems with substantial operations and maintenance costs

Creator:: Algarra, Nathan
Abstract:: Long field-life systems are those for which operational, as opposed to capital, expenditures dominate the life time cost of the system. In established product categories, operational experience and historical maintenance data allows engineers to make informed decisions influencing maintenance during the early design stages when design changes are at their...
