Methane Production By A Packed-Bed Anaerobic Digester Fed Dairy Barn Flush Water, Sean Richard Thomson
Methane Production By A Packed-Bed Anaerobic Digester Fed Dairy Barn Flush Water, Sean Richard Thomson
Master's Theses
Packed-bed digesters are an alternative to covered lagoon digesters for methane production and anaerobic treatment of dilute wastewaters such as dairy barn flush water. The physical media of packed-beds retain biofilms, often allowing increased treatment rates. Previous studies have evaluated several types of media for digestion of dilute wastewaters, but cost and media fouling have setback commercial development. A major operational cost has been effluent recirculation pumping.
In the present effort, a novel approach to anaerobic digestion of flush dairy water was developed at pilot-scale: broken walnut shells were used as a low-cost packed-bed medium and effluent recirculation was replaced …

Field To Flight: A Techno-Economic Analysis Of Stover To Aviation Biofuels Supply Chain, Amanda C. Bittner
Field To Flight: A Techno-Economic Analysis Of Stover To Aviation Biofuels Supply Chain, Amanda C. Bittner
Open Access Theses
Greenhouse gas emissions have been a growing concern. The transportation sector contributes to one-third of GHG emissions in the United States from fossil fuel burning. The Renewable Fuel Standard set a requirement for 16 billion gallons (ethanol equivalent) of cellulosic biofuels to be used in the market. Aviation biofuels can help to meet both of these problems as well as improve U.S. energy security.
Investment in the biofuel industry carries a lot of risk. The biofuel industry is run by the private sector, but can be incentivized by government. Cellulosic biofuels carry even more risk than first generation biofuels, because …

Risky Business: Recommendations For The Insurance Industry To Contribute To Greater Disaster Risk Reduction And Climate Change Adaptation, Jessie G. Rountree
Master's Projects and Capstones
The private insurance industry is susceptible to increasing risk from climate change and can serve as a catalyst to change behavior to minimize loss. The research examined the current impact and future potential of the insurance industry to reduce both physical and financial risk. The insurance industry currently raises awareness, assigns an economic value to risk, advocates for climate change action, and takes measures to reduce physical risk through mitigation. As well, the industry has proven to be a critical influencer to encourage risk-adverse behavior and regulation. Recommendations to the industry to have a greater impact include: 1) pursue more …
A Decrepit New York: Synthesizing New York’S Infrastructure Problems, Connor Farrell
A Decrepit New York: Synthesizing New York’S Infrastructure Problems, Connor Farrell
2014 Student Theses
Coastal living has become a very popular, often fantasized, way of life. This lifestyle is easy, relaxing, and, above all, it soothes the stress. However, mankind’s innate desire to live near America’s oceans, rivers, and other bodies of water have allowed its population to become vulnerable to super storms. Super storms, such as Hurricane Sandy, have become more prevalent over recent years, and America needs to take into account the massive population whom call the East coast home. Focusing in on the New York area, I will be able to show how our thoughtless designs and locations of towns/cities have …

Spreading The Char: The Importance Of Local Compatibility In The Diffusion Of Biochar Systems To The Smallholder Agriculture Community Context, Laura C. V. Munoz
Spreading The Char: The Importance Of Local Compatibility In The Diffusion Of Biochar Systems To The Smallholder Agriculture Community Context, Laura C. V. Munoz
Pomona Senior Theses
This thesis enters the context of smallholder agriculture communities in the developing world. It explores the potentials of biochar and what biochar systems could bring to the smallholder communities while simultaneously bringing environmental benefits. It then acknowledges the challenges of diffusion –the spreading of an unfamiliar innovation. It seeks to answer the question of what will make diffusion of biochar systems more successful in the smallholder context, fixating on the characteristic of compatibility as well as the role local community members can play in making a new biochar system more visible to the rest of the communities.
Three Essays On The Role Of It In Environmental Sustainability: Motivating Individuals To Use Green It, Enhancing Their User Experience, And Promoting Electricity Conservation, Abdullah Al Bizri
Theses and Dissertations
This dissertation focuses on the role of IT in environmental sustainability and electricity conservation through three research essays. The first essay makes a case for behavior research, with the focus on individuals' use of Green IT. Moreover, environmental studies lack a coherent theory that could identify the motivators of Green-IT beliefs. We develop the hedonic motivation theory, which synthesizes theoretical and philosophical thoughts on hedonism with concepts from environmental research. Using this theory, we develop a conceptual model that identifies the motivators of context-specific beliefs, attitudes, and uses of Green IT. We theorize that there are significant generational differences in …
A Global Investigation Of Stakeholder And Contextual Influences On Firm Engagement In Sustainability, Annette M. Nemetz
A Global Investigation Of Stakeholder And Contextual Influences On Firm Engagement In Sustainability, Annette M. Nemetz
Dissertations and Theses
Global sustainability issues cross all sectors of society, including businesses, governments, and communities and come with substantial costs. Business organizations are increasingly expected to address sustainability issues in a responsible manner and to disclose socially responsible behaviors accurately and transparently, showing that they are effective at managing and being proactive about sustainability challenges. In light of these pressures and expectations for business organizations, the fundamental research question for this study was whether variation existed in the levels of engagement in sustainability efforts across firms globally, and, more importantly, why such variation existed.
The level of strategic firm engagement in sustainability …
Compatibility Between Business And The Environment: Examples From A Case Study Of Patagonia, Ellesha Gasperini
Compatibility Between Business And The Environment: Examples From A Case Study Of Patagonia, Ellesha Gasperini
International Political Economy Theses
A relatively new concept, corporate environmentalism refers to the action corporations are taking to become more conscience of their environmental impacts. Using a case study of the company Patagonia, the dual motivations that exist for it and other companies to adopt more environmentally friendly policies are used to argue that environmental responsibility in business is possible. These motivations are values and beliefs held by those inside a company and financial gains found in corporate sustainability. Although there still exist many barriers, such as financial markets, lacking consumer education, and global complexity, businesses are taking steps to overcome these obstacles. The …

The Effects That Liquid And Solid Cattle Manure Have On The Water Quality Of Drainage Ditches In Putnam County, Ohio, Janelle Horstman
Honors Projects
Lake Erie has experienced harmful algal blooms with increased frequency since the mid-1990s due to excess nutrients from Rivers, such as the Maumee River, and largely agricultural watersheds. Nonpoint source pollution from agriculture contributes to eutrophication, algal blooms, and the degradation of water quality. This creates stress on aquatic fauna, reduced aesthetic quality, odor, and limits of the water for usage of drinking, recreation, and industry. This research paper asks what the contributions of having access to manure application records, soil records, and information about antibiotics have on what is known about manure management and antibiotic resistance, which has been …
