Anaerobic Co-Digestion of Municipal Sludge and Fats, Oils, and Greases: Effects on Digester Performance and Microbial Community Dynamics

Creator:: Berninghaus, Ashley E.
Abstract:: The natural production of methane via anaerobic digestion (AD) is facilitated by a complex community of microorganisms, primarily bacteria and archaea, referred to as the AD microbiome. AD is growing in prominence as a solution to the disposal of food waste, sewage sludge, and the organic fraction of municipal solid...

Effects of Step-Wise Acclimation versus Shock Loading on the Performance of Anaerobic Co-Digestion of Fats, Oils, and Greases

Creator:: Berninghaus, Ashley E.
Abstract:: Anaerobic digestion is a microbially mediated process by which organic matter is decomposed in the absence of oxygen. The end products of anaerobic digestion include treated sludge and biogas, a mixture of methane and carbon dioxide, which can be recovered and used for energy generation. The majority of wastewater treatment...

A Comparison of Ammonia Inhibition on the Anaerobic Digestion of Organic Acids Between Digestate from Anaerobic Co- and Mono-Digestion Systems

Creator:: Ruiz-Orozco, Gloria
Abstract:: Anaerobic digestion is a common terminal step in wastewater treatment systems and produces valuable by-products such as biogas, a combination of carbon dioxide and methane. Biogas can be used to off-set energy costs, and along with the anaerobic co-digestion of fats, oils, and greases (FOG) has been found to increase...

Youth Vaping Epidemic: LGBTQ+ Youth

Creator:: Bhupalam, Ratna
Abstract:: In the United States, rates of youth vaping are alarmingly high. In 2018, the U.S Surgeon General declared youth vaping as an epidemic (Truth Initiative, 2019a). However, LGBTQ+ youth are disproportionately affected. In 2017, current e-cigarette usage in youth was 13.2% among heterosexuals, but was 17.5% in LGBTQ+ youth (CDC,...

Biogas inhibition of fats, oils, and greases with varying ammonia levels

Creator:: Aranda, Ana A.
Abstract:: Biogas can be used to generate energy from a wide variety of sources. Wastewater treatment sludge is an effective source of waste to be used for generation of biogas to make energy which can be used to heat homes and run businesses. This would help decrease the use of fossil...

The COVID-19 pandemic’s effect on outdoor recreation

Creator:: Davis, Jensen
Abstract:: In the spring of 2020, the COVID-19 pandemic began. This prompted quarantines, mask mandates, and stopped many businesses and services. This study asked the question of what people decided to do in terms of their recreation habits in response to the pandemic. We took a sample of Oregon State University...

Using Interpretive Signs and Theory-based Messaging to Protect the Western Snowy Plover (Charadrius alexandrinus nivosus)

Creator:: Schoenleber, Carli
Abstract:: Although the human health and social benefits from outdoor recreation are numerous, there is mounting evidence that outdoor recreation can negatively impact wildlife. Shorebirds are known to be especially sensitive to recreation-related disturbance because they nest and forage directly on beaches that are often used for recreation. Many studies have...

Wading through Space and Time: Leveraging Geospatial Methods to Better Understand Recreation Behavior, Experience, and Impacts within a Densely Used Lake Destination

Creator:: Baker, Jenna T.
Abstract:: In the last decade, many U.S. parks and protected areas (PPA) experienced record breaking visitation levels. Managers of these PPAs face the challenging task of providing a range of quality and accessible outdoor experiences without compromising the integrity and health of surrounding ecosystems. Understanding how PPA visitors move and interact...
