“Trash Talk” - Rethinking The Notion Of Waste, Shivaangi Salhotra

Student Showcase

In the twenty-first century, waste has become a ubiquitous problem. Images of things like the Great Pacific Garbage Patch have ceased to become jarring, and pictures of overflowing landfills and statistics about plastic in the ocean have become so commonplace that they are “memed”. Yet despite increasing awareness and changes in policy, global waste production and its deleterious effects continue to rise. Dominant narratives surrounding waste tend to focus on how individuals can properly dispose of their waste, which, while certainly important, is not the full story. It doesn't question why we produce so much waste in the first place, …

Anaerobic Membrane Bioreactors As A Treatment For Wastewater And Biogas Production At University Of Massachusetts Amherst, Marley Norton, Brady Bell, Ariel Fine

Student Showcase

Achieving carbon net neutrality at UMass by the year 2032 would require an unprecedented scale of renovation. However, we stand before an opportunity to set a nationwide standard in college campus sustainability. The usage of water also requires energy, as both are inextricable commodities, high in demand and often non-renewable. The central heating plant (CHP) distributes heat across the 1,400+ acre campus and consumes copious amounts of natural gas. A viable solution to relieving the dominant reliance on non-renewable energy without leaving the CHP as a stranded asset revolves around the implementation of a hybrid low temperature hot water system …

This proposal to UMass Amherst is for all campus offices to switch their employee time reporting operations to a universal electronic system in the interest of reducing paper and saving time. Waste reduction, including paper consumption, is a top priority for the administration and the campus, as it is for college campuses across the nation. As a Green Office Fellow in the Green Office Program within Sustainable UMass at UMass Amherst I conducted an electronic survey for my fellowship project during the Fall 2018 semester. This survey asked campus offices for information about their time reporting operations.

From Planning To Passing: The Amherst, Massachusetts Plastic Bag Ban, Kevin J. Hollerbach

Student Showcase

This case study will detail the background and influences for a plastic bag ban in the town of Amherst, outline the steps taken from planning to passage, and address roadblocks and missteps that may be avoided with the implementation of future bans. It is my hope that this document will not only serve as a guide, but also an inspiration for additional local action in Massachusetts and across the country. No matter what the national political climate or attitude towards environmental issues, local action is always possible, and change is usually easier than you think. Think globally, act locally!

The Perfect Storm: Lasting Impacts Of Structural Adjustment Programs And Pressures Of Climate Change In Latin America And Ghana, Africa, Sam Kefferstan

Student Showcase

This work examines the intersectionality of economic, social and environmental impacts of the International Monetary Fund’s and World Bank’s application of structural adjustment programs (SAPs) within Latin America and Ghana, Africa. Varying economic and social indicators illustrate the underperformance of SAPs in their intended mission to reduce poverty and debt in developing nations. This research argues Gross Domestic Product is an imperfect measure of improving quality of life and points towards other indicators such as increasing national debt, rising incidences of poverty, and exacerbated regional disparities to demonstrate the shortcomings of SAPs. This piece also investigates the limitations adjustment imposes …

The guide also presents actionable policy recommendations for the University to reduce waste and increase diversion from large-scale outdoor events on the UMass Amherst campus.

What Will It Take To Make Solar Panels Cool?, Luke Fateiger, Cameron A. Lane, M. Donald Rollings, Cameron J. Smith-Freedman

Student Showcase

With the predicted results of climate change looming, humanity must do all it can to limit greenhouse gas emissions. Maintaining a habitable environment along with the high quality of living associated with developed nations requires investment in renewable energy. Because national governments often fail to make responsible decisions for their country's future, this burden falls to institutions like UMass Amherst. Although costly investments like solar panels substantially improve the sustainability of campus, some innovative improvements of existing solar energy infrastructure can go a long way. For example, when solar panels heat up they lose photovoltaic efficiency. We propose that UMass …

Shaping Carbon Nanotube Forests For Field Emission, Benjamin Pound

Student Showcase

Field emission is a phenomenon where electrons are extracted from a conducting material by an external electric field. This effect has been used for electron sources for many applications, from electron microscopes to flat-panel displays. One undesirable feature of field emitters is that they often require high turn-on voltages. One way to improve the field emission is to decrease the tip size. In previous works, single carbon nanotubes (CNTs) with nanometer tip sizes have been used as field emitters, and have achieved currents comparable or higher than commercial field emitters at relatively low operating voltages. However, the single CNT field …

Why Waste The Wind? A Look Into Small Scale Wind Energy, Mitchell Negus, Jon Swanton, Ben Chilcoat, Mark Settembrino

Student Showcase

The human race’s dependence on fossil fuels for energy generation has started to cause major changes in the environment. Climate change is a universal issue and it is evident that our current energy schematic is not sustainable. At the University of Massachusetts, small-scale wind power has the potential to be a key component in UMass’ energy portfolio as the university shifts from reliance on fossil fuels to renewable energy. Strategically placed turbines would produce clean, renewable energy, reduce greenhouse gas emissions, and help to decentralize energy dependence on the Central Heating Plant. Small-scale turbines, like the eddyGT, are tested technologies …

Changing climate and increasing costs of energy are putting pressure on the building industry to adapt to higher performance building systems. One technology that can improve building performance is structural insulated panel (SIP) construction. The purpose of my practicum is to evaluate the possible benefits of SIPs and to identify obstacles to SIPs gaining a larger portion of the building industry. Using the information from practicum I intend to evaluate current design tools and suggest my own tools. The benefits of SIPs are lower thermal bridging and air infiltration leading to lower operating costs and minimal material usage. Findings include …

Overtone Analysis Of A Holtkamp Organ Using Fourier Methods, Mario Harper, David Berg

Student Showcase

This research is a study of the similarities and differences of the four sound families (principal, flute, reed, and string) of the organ, specifically, we used the organ located in the Kent Hall at USU. This experiment focuses on the mechanics of the organ, turning sound into mathematical signals, and performing Fourier analysis using computer methods. We conclude that a certain family of pipes (flute pipe family) had the most similarities to the “natural” series while the reed family was the most variant. We show the steps taken in our experiment and attempt to explain the variance and correlation of …

Functionalizing Carbon Nanotube Forests, Ben Pound, F. K. Shen

Student Showcase

A carbon nanotube forest is an array of carbon nanotubes vertically aligned and entangled. Because the aspect ratio of each tube can be more than 1000, the forest will greatly increase the number of potential binding sites on the surface for chemical and biological detector applications, if each bundle of tubes can be functionalized with specific molecules. The 1,5-diaminoaphthalene can be a versatile linker molecule for proteins. In this study, we characterize the concentration of 1,5-diaminoaphthalene in solvent by fluorescence spectroscopy. It appears, however, that the solvent collapses the carbon nanotube forest, resulting in no detectable fluorescence emission. Lithographically defined …

Simulation Chamber For Space Environment Survivability Testing, Robert H. Johnson, Lisa D. Montierth

Student Showcase

A vacuum chamber was designed and built that simulates the space environment making possible the testing of material modification due to exposure of solar radiation. Critical environmental components required include an ultra high vacuum (10-9 Torr), a UV/VIS/NIR solar spectrum source, an electron gun and charge plasma, temperature extremes, and long exposure duration. To simulate the solar spectrum, a solar simulator was attached to the chamber with a range of 200nm to 2000nm. The exposure time can be accelerated by scaling the solar intensity up to four suns. A Krypton lamp imitates the 120 nm ultraviolet hydrogen Lymann alpha emission …

Galaxy Inclination And Surface Brightness, Jordan C. Rozum, Shane L. Larson

Student Showcase

The distribution of spiral and bar galaxy inclination angles is expected to be uniform. However, analysis of several major galaxy catalogs shows this is not the case; galaxies oriented near edge-on are significantly more common in these catalogs. In an attempt to explain this discrepancy, we have developed a galaxy simulation code to compute the appearance of a spiral type galaxy as a function of its morphological parameters. We examine the dependence of observed brightness upon inclination angle by using smooth luminous mass density and interstellar medium (ISM) density distributions. The luminous mass component is integrated along a particular line …

Micrometeoroid From Misse Examined To Understand The Effects Of The Space Environment On Space Suit Materials, Kelby T. Peterson
