Circular Economy And The Potential For Extended Producer Responsibility Policies, Erin Quinn
Circular Economy And The Potential For Extended Producer Responsibility Policies, Erin Quinn
Senior Honors Projects, 2020-current
This thesis was developed based on an Extended Producer Responsibility (EPR) Policy briefing I created during my internship at RISE (Responsible Industry for a Sound Environment) during the summer of 2021. This project expands upon the work created during the internship. It examines the connection between circular economy and EPR policies, as well as how they can create effective strategies for waste reduction and recycling in the U.S. It demonstrates how the current linear economic system under which the U.S operates and its connection to single-stream recycling are inefficient at best. The thesis then describes how a circular economy (CE) …
Photocatalytic Degradation Of Organic Contaminants By Titania Particles Produced By Flame Spray Pyrolysis, Noah Babik
Photocatalytic Degradation Of Organic Contaminants By Titania Particles Produced By Flame Spray Pyrolysis, Noah Babik
Theses and Dissertations
Advanced oxidation of organic pollutants with TiO2 photocatalysts is limited due to the wide bandgap of TiO2, 3.2 eV, which requires ultraviolet (UV) radiation. When nanosized TiO2 is modified by carbon doping, charge recombination is inhibited and the bandgap is narrowed, allowing for efficient photodegradation under visible light. Here, we propose a flame spray pyrolysis (FSP) technique to create TiO2. The facile process of FSP has been successful in preparing highly crystalline TiO2 nanoparticles. Using the same procedure to deposit TiO2 onto biochar, the photocatalyst was doped by the carbonaceous material. The morphology, crystalline and electronic structure of the FSP …
Evaluating Soil Health Changes Following Cover Crop And No-Till Integration Into A Soybean (Glycine Max) Cropping System In The Mississippi Alluvial Valley, Alexandra Gwin Firth
Evaluating Soil Health Changes Following Cover Crop And No-Till Integration Into A Soybean (Glycine Max) Cropping System In The Mississippi Alluvial Valley, Alexandra Gwin Firth
Theses and Dissertations
The transition of natural landscapes to intensive agricultural uses has resulted in severe loss of soil organic carbon (SOC), increased CO₂ emissions, river depletion, and groundwater overdraft. Despite negative documented effects of agricultural land use (i.e., soil erosion, nutrient runoff) on critical natural resources (i.e., water, soil), food production must increase to meet the demands of a rising human population. Given the environmental and agricultural productivity concerns of intensely managed soils, it is critical to implement conservation practices that mitigate the negative effects of crop production and enhance environmental integrity. In the Mississippi Alluvial Valley (MAV) region of Mississippi, USA, …
Smart Grid Control: Demand Side Management In Household Refrigerators As A Tool For Load Shifting, Anogh Utkalika Zaman, James Doyle
Smart Grid Control: Demand Side Management In Household Refrigerators As A Tool For Load Shifting, Anogh Utkalika Zaman, James Doyle
Macalester Journal of Physics and Astronomy
With improved supply of renewable sources of energy the focus has shifted away from simply producing clean energy to efficient consumption of energy. Until cheaper methods of energy storage are developed, Demand Side Management (DSM) is the best option for maximising energy efficiency. This paper proposes a method of turning regular refrigerators into smart demand response fridges. First, we develop an algorithm that accounts for small fluctuations in price and switches the device for optimal performance and lowered running cost. Then, we use longer price fluctuations to predict suitable times for pre-cooling and investigate the reduction in price as a …
Using Lidar To Estimate Carbon Sequestration Of Evergreen Trees At Eastern Washington University (Ewu) Campus, Cheney, Washington, Kristy A. Snyder
Using Lidar To Estimate Carbon Sequestration Of Evergreen Trees At Eastern Washington University (Ewu) Campus, Cheney, Washington, Kristy A. Snyder
2022 Symposium
EWU contains a variety of deciduous and evergreen trees across its campus, providing several benefits. However, no comprehensive record exists of the total number, location, species, or ages of these trees. This knowledge can inform facilities of proper care for individual trees and can be used to estimate carbon sequestration on campus. Traditional on-the-ground methods for assessing trees require tree cores or clinometers, making trees susceptible to pests or disease and leading to inaccurate results. Remote sensing using lidar data is a noninvasive, more precise method to measure tree height and subsequently assess tree age. This poster explores using point …

Teaching & Learning Guide For Disability And Climate Justice, Molly M. King, Maria A. Gregg, Ana V. Martinez, Emily Y. Pachoud
Sociology
Disability is widespread: nearly one in four Americans has a disability (Taylor, 2018) and disability cuts across demographic categories. Among individuals aged 15 and over, 12.6% had some type of mobility disability; above age 65, it is nearly 40% (Brault, 2012). Mobility disabilities heighten vulnerability to climate change and climate-related disasters (UNHCHR, 2020). Reduced information resources and mobility, increased health risks, and a lack of visibility in climate change discourse put people with disabilities in a more vulnerable position in the climate crisis. However, this vulnerability can be mitigated through relevant and sufficient access to information, risk mitigation …
Sustainable Rural Development: Is It Possible To Boost Rural Economies While Protecting The Environment?, Jack M. Hempleman
Sustainable Rural Development: Is It Possible To Boost Rural Economies While Protecting The Environment?, Jack M. Hempleman
Undergraduate Theses, Capstones, and Recitals
Amidst rapid depletion of our carbon budget, the need to change our practices to be more in line with Earth’s limits has become important in every sector of our economy. From advances in renewable energy generation to the growth of urban gardening, people around the world are taking action to change the way they interact with our planet. However, growing concerns have been raised that protections for the environment will disproportionately harm struggling communities. For instance, rural communities in the United States already exhibit disproportionately high poverty rates, income inequality, and unemployment, as well as lower quality healthcare and public …
More Crops, Less Drops? Agriculture And Climate Interactions Via Soils, Sonali Shukla Mcdermid
More Crops, Less Drops? Agriculture And Climate Interactions Via Soils, Sonali Shukla Mcdermid
Sustainability Seminar Series
There is an increasing focus on reducing agricultural GHG emissions, while also facilitating cropping systems’ adaptation to climate change. Much of this combined agriculture mitigation and adaptation work centers on managed soils’ carbon and nutrient processes, and interactions with water. I will present two on-going projects evaluating agricultural soil-water-crop interactions and discuss implications for climate mitigation and/or adaptation. I will first describe new, on-going work using an integrated climate-crop modeling framework to Asia. Preliminary results suggest that while specific combinations of management options, including conservation water and soil management, can provide mitigation and adaptation benefits, several trade-offs may exist between …

Scholarship and Professional Work - LAS
Given the ongoing socio-ecological crises, higher education institutions need curricular interventions to support students in developing the knowledge, skills, and perspectives needed to create a sustainable future. Campus farms are increasingly becoming sites for sustainability and environmental education toward this end. This paper describes the design and outcomes of a farm-situated place-based experiential learning (PBEL) intervention in two undergraduate biology courses and one environmental studies course over two academic years. We conducted a mixed-method study using pre/post-surveys and focus groups to examine the relationship between the PBEL intervention and students’ sense of place and expressions of pro-environmentalism. The quantitative analysis …
