A Laboratory-Scale Study On The Production Of High-Value Products From Broiler Litter Involving Solid-State Anaerobic Digestion And Mushroom Cultivation, Joe Barrett Carter Iii

Graduate Theses and Dissertations

There is a need to investigate alternate uses and treatments of broiler litter that lessen environmental impacts and decrease costs associated with its disposal. Anaerobic digestion is a biological process in which organic material is converted to a renewable fuel source. However, the substrate for anaerobic digestion often requires some form or pretreatment. Certain types of fungus have been investigated as a pretreatment for anaerobic digestion, one of which is Pleurotis ostreatus or the oyster mushroom, which also produces an edible fruiting body. Thus, this study was performed to investigate the use of broiler litter for oyster mushroom cultivation and …

An Economic Analysis Of Residential Photovoltaic Systems With And Without Energy Storage, Rodney Moses Kizito

Graduate Theses and Dissertations

Residential photovoltaic (PV) systems serve as a source of electricity generation that is separate from the traditional utilities. Investor investment into residential PV systems provides several financial benefits such as federal tax credit incentives for installation, net metering credit from excess generated electricity added back to the grid, and savings in price per kilowatt-hour (kWh) from the PV system generation versus the increasing conventional utility price per kWh. As much benefit as stand-alone PV systems present, the incorporation of energy storage yields even greater benefits. Energy storage (ES) is capable of storing unused PV provided energy from daytime periods of …

The Impact Weather Has On Nyc Citi Bike Share Company Activity, Mark Martinez

Journal of Environmental and Resource Economics at Colby

This study examines the demographics of California’s 53 congressional districts and the relationship with the voting patterns on three environmentally focused propositions in the 2008 and 2010 elections. Previous literature on the topic is mixed as some studies suggest that select attributes are found among environmental voting centers, yet other research describes the relationship as more complex than simple characteristics. Previous literature on the topic is mixed, with some studies suggesting that select attributes are found among environmental vote support hubs, whereas alternative research suggests the problem is more complex than simple characteristics. I collected data on income, education, age, …

The Long-Term Effect Of State Renewable Energy Incentive Programs, Fred Bower

Journal of Environmental and Resource Economics at Colby

Abstract: Renewable energy is praised for its environmental benefits and long run energy savings, however, for the average consumer, the up-front cost of this infrastructure deters investment. On the Federal and state level, incentive programs have been implemented to break down these initial barriers and give easier access to renewable energy. Studies have shown that these incentive programs have been successful at the consumer level (Crago, 2014). What policy makers and government officials should maybe be more concerned with though, is the long-term effect of these programs. This paper will analyze the long-term effect of renewable energy incentive programs beyond …

The Effects From Public Transportation On Property Values: A Closer Look At Scituate, Hanover, And Norwell, Massachusetts, Alexandra Taylor Perticone, Christine S. Coveney

Journal of Environmental and Resource Economics at Colby

Prior studies have expressed the value of location in real estate, but more recent studies have explored the influence that public transportation has had on housing prices. Access to public transportation is understood to increase the value of homes. Easier access to public transportation allows for shorter and more convenient commutes into or within cities. However, other studies have found that proximity to public transportation can also have adverse effects on property values. This paper investigates whether the implementation of the Greenbush Commuter line in Massachusetts in October 2007 increased the housing prices in Scituate, Ma--the furthest town from the …

When Trash Costs Money: Analyzing The Impact Of Pay-As-You-Throw Programs In Massachusetts, Thomas W. Barry Iv

Journal of Environmental and Resource Economics at Colby

This paper evaluates whether municipalities with Pay-As-You-Throw (PAYT) programs dispose of less trash per household than municipalities without them. Given how much trash U.S. residents produce, the negative environmental effects associated with trash disposal, as well as how much the U.S. Environmental Protection Agency advocates for PAYT, it is important to closely analyze whether these programs actually do their job. This paper formally analyzes the effects of PAYT programs using the Massachusetts Department of Environmental Protection’s trash disposal data from 2011-2015. After controlling for municipality and time heterogeneity, my analysis shows that PAYT programs reduce trash per household by a …

One-Step Laser-Induced Hydrogen Generation From Coal Powders In Water, Dovletgeldi Seyitliyev

Masters Theses & Specialist Projects

This study presents a simple way of obtaining hydrogen gas (H2) from various ranks of coal, coke, and graphite using nanosecond laser pulses. Powder samples of coal and graphite with and without water were irradiated with 1064 nm and 532 nm pulses from an Nd: YAG laser for 45 minutes under air and argon atmospheres. It was observed that 532 nm laser pulses were more effective than 1064 nm pulses in gas generation and both were nonlinearly correlated with respect to the laser energy density. Mainly hydrogen (H2) and carbon monoxide (CO) were observed. The H2 to CO ratio shows …

Solvent Degradation And Emissions From A 0.7mwe Pilot Co2 Capture System With Two-Stage Stripping, Jesse Thompson, Heather Nikolic, Megan Combs, Saloni Bhatnagar, Jonathan Pelgen, Keemia Abad, Kunlei Liu

Center for Applied Energy Research Faculty and Staff Publications

The UKy-CAER team successfully tested an advanced 0.7 MWe post-combustion CO₂ capture system on a coal-fired power plant using a heat integration process combined with two-stage stripping to enhance the CO₂ absorber performance. One of the unique feature of the UKy-CAER integrated process is a two-stage stripping unit for solvent regeneration. The secondary stripper is empowered by the heat rejection from a conventional steam-heated (primary) stripper. The secondary stripper outlet stream at the commercial scale can be used as boiler secondary combustion air, consequently enriching the flue gas with CO₂, resulting in less energy penalty required …

Extraction Of Oil From The Bakken Shales With Supercritical Co2, Lu Jin, Steven B. Hawthorne, James A. Sorensen, Bethany A. Kurz, Steven A. Smith, Loreal V. Heebink, Nicholas W. Bosshart, José A. Torres, Chantsalmaa Dalkhaa, Charles D. Gorecki, Edward N. Steadman, John A. Harju

EERC Publications, Papers, & Presentations

Results from 20 samples showed that supercritical CO₂ enables extraction of a considerable portion (15%–65%) of the hydrocarbons from the Bakken shales within 24 hours. The results may be used to improve modeling and forecasting the effects of CO₂ enhanced oil recovery (EOR) and suggest the possibility for increasing ultimate recovery, and possibly CO₂ storage, in some areas of the Bakken Formation.

Pore Resolved Simulations Of Char Particle Gasification, Greg Hingwah Fong

Master's Theses (2009 -)

Coal is a significant source of energy in today’s world and many studies have been conducted in order to better understand and optimize its use. To address greenhouse effects associated with coal combustion, cleaner methods for harnessing its energy are being explored. One such method is gasification, a process which converts coal into syngas, a mixture consisting primarily of H2 and CO. Syngas can be used to generate electricity or to produce hydrocarbons that can be used as fuels. To better understand and optimize the process, simulations can be used to study the gasification of individual porous char particles that …

Fossil Fuel Asset Risk Analysis: Clark University Endowment, Travis A. Dodge, B. Maiwand Akbari

Student Works

The environmental and social risks of climate change are well known and perhaps inevitable. The economic and financial risks are less so. The many financial risks associated with climate change embedded in endowment portfolio fossil fuel holdings are leading many institutional stakeholders to enter into dialogue and take action. Divestment is emerging as an effective strategy for limiting portfolio exposure and tackling climate change itself.

Our team’s goals were to assess whether the Clark University endowment portfolio faces any of these risks and evaluate the impacts on asset values. Our findings show that the Clark endowment does face these same …

Comprehensive Silica Removal With Ferric Compounds For Industrial Wastewater Reuse, Ehren D. Baca

Civil Engineering ETDs

Cooling towers, integrated circuit (IC) manufacture and reverse osmosis (RO) generate copious amounts of wastewater high in colloidal and reactive silica inhibiting on-site or synergistic reuse. Silica present in cooling water can reach solubility limits via evaporation and form impervious scale on heat transfer surfaces that decreases efficiency. When water is treated by RO operating at high rejection, silica forms difficult-to-remove scale on the membrane feed side in the form of glassy patches and communities of aggregate particles, inhibiting aspirations for zero liquid discharge. Current methods for silica scale mitigation include abundant dosing with chemical antiscalents or complex operating schemes. …

Economic Evaluation Of Coastal Land Loss In Louisiana, Stephen R. Barnes, Craig Bond, Nicholas Burger, Kate Anania, Aaron Strong, Sarah Weilant, Stephanie Virgets

Journal of Ocean and Coastal Economics

Louisiana has lost approximately 1,880 square miles of land over the past eighty years. Projections suggest that in a future without action, the next fifty years could result in the loss of 1,750 additional square miles of land area. As land loss continues, a large portion of the natural and man-made capital stocks of coastal Louisiana will be at greater risk of damage, either from land loss or from the associated increase in storm damage. We estimate the replacement cost of capital stock directly at risk from land loss ranges from approximately $2.1 billion to $3.5 billion with economic activity …

Examining The Effects Of Policy Interventions On Increasing Electric Vehicle Adoption In California, Ethan G. Mcdermott

Master's Projects and Capstones

Any significant effort to reduce global emissions of greenhouse gasses must address the growing concern of the transportation sector’s inability to meaningfully reduce its emissions contribution. A major shift in the primary fuel used in the sector away from petroleum-based fuel to electricity is one potential way the sector can lower its emissions and transition into a sustainable future. However, a number of barriers face the electric vehicle market, including competing against an already mature vehicle market, battling consumer preferences, and overcoming technical challenges. This paper examines several policy proposals to combat these barriers and examines the impact similar policies …

With Hawaii’s high annual solar radiation, PV generation could play a significant role …

California Public Electric Vehicle Charging Stations’ Accessibility To Amenities: A Gis Network Analysis Approach, Jeremy Yun Li Chen

Master's Projects and Capstones

In California, the number of electric vehicles (EVs) on the roads has been increasing over the past several years. As EVs continue to grow, additional electric vehicle charging stations (EVCSs) will be needed for EV drivers to utilize. However, before implementing EVCSs in the public, there are various criteria that need to be considered. One of these criteria is public EVCSs’ accessibility to amenities. When people are charging their EVs that require a significant amount of waiting time, having amenities nearby will provide them with the option to spend their time efficiently on worthwhile activities. To understand the accessibility of …

Sub 2 Nm Particle Characterization In Systems With Aerosol Formation And Growth, Yang Wang

McKelvey School of Engineering Graduate Student Theses & Dissertations

Aerosol science and technology enable continual advances in material synthesis and atmospheric pollutant control. Among these advances, one important frontier is characterizing the initial stages of particle formation by real time measurement of particles below 2 nm in size. Sub 2 nm particles play important roles by acting as seeds for particle growth, ultimately determining the final properties of the generated particles. Tailoring nanoparticle properties requires a thorough understanding and precise control of the particle formation processes, which in turn requires characterizing nanoparticle formation from the initial stages. The knowledge on particle formation in early stages can also be applied …

Software Development For Home Energy Audits: Reducing Energy Consumption In Harrisonburg Through Technology, Brantley E. Gilbert

Senior Honors Projects, 2010-2019

Fossil fuels play a vital role in our daily lives. Oil, natural gas, and coal powers our cars, heats our homes and water, and are used by power companies to generate the massive amounts of electricity used every day by the United States. However, this reliance on a finite source of energy is not sustainable. Fossil fuels such as these are non-renewable resources whose production will eventually be unable to keep up with the rate of consumption. Furthermore, the extraction of the stored energy in these fuels through combustion releases harmful substances into the environment, including toxins and greenhouse gases …

Sustainability and Social Justice

The purpose of this report is to examine the impact of the water-energy nexus in the United States, and identify opportunities for increased collaboration between water and energy utilities. Through reviewing the regulatory history of both sectors, I explore how regulations on utilities align with the Porter Hypothesis, and the impacts the water-energy nexus will have moving forward, including under climate-change scenarios. The extent of collaboration between sectors has been relatively limited to states with progressive energy and water efficiency policies. This report identifies existing barriers and benefits to collaboration, and utilizes two case studies; California and Massachusetts. Results are …

An Analysis Of Structural And Psychological Barriers To The Adoption Of Demand Response Smart Grid Technologies: Lessons Learned, John M. Richards

Sustainability and Social Justice

Over the past decade, America’s utility grid has undergone fundamental changes on a scale not seen during the past 100 years (Energetics Incorporated, 2014). These changes have largely been driven by the need to replace aging infrastructure, modernize the grid, incorporate new sources of energy, and better balance the supply and demand of energy. In order to address some of these changes, utilities have increasingly implemented smart grid programs that provide customers with consumer-focused demand response technologies that aim to reduce peak demand. This report examined the success these technologies have in reducing peak demand for smart grid programs by …

Pine Needle Pyrolysis: Bio-Waste Into Biofuel, Alexandra Fuentes

Scholarly and Creative Works Conference (2015 - 2021)

This project explores the alternate uses of biomass. In particular, it focuses on pine needles as a source for biofuels. Pine needles are of interest because in certain Mountain communities they are collected and removed from residential properties. By removing the pine needles, communities create a “defensible space” to prevent wild fires from destroying homes. These needles are often placed in regional landfills. The South Tahoe Refuse and Recycling Services alone has more than 4,340 tons of pine needles dumped at their facility annually. This large amount of biomass can be a potential energy source.

The focus of this research …
