This research paper explores how different relationships between people and nature can be fostered by learning experiences to bridge harmful gaps in the field of sustainability. Current disconnectedness from nature and people both within and across geographical borders hinder the cultivation of sustainable solutions. After attending a sustainability-oriented educational experience abroad in Ecuador recently, I decided to investigate how cross-cultural exchanges in Ecuador influences participants’ views of nature, new points of intersectionality participants learn while amongst nature in Ecuador, and what about this experience made it uniquely meaningful. Research methods included individual interviews and a group hike and picnic focus group discussion to collect qualitative data. I found that during this experience, students were able to lean into being vulnerable with each other, connect with indigenous community members beyond language borders, and connect with nature in ways that fostered awareness of the human position within it. From this, I learned that there were unique aspects of this learning experience that allowed for these relationships to be built and therefore for sustainable knowledge from the trip to stick when participants got back to the United States. The amount and flexibility of learning and processing time and dynamics created by classroom structure were important variables to the effectiveness of the learning experience. Institutions can learn from these experiences and connect people back to nature to implement successful sustainability solutions in the future.

The environment today is facing concerns over accumulation of plastics in landfills as well as excessive CO2 emissions. Containers and packaging take up approximately 15 million tons each year, and accumulations such as the Great Pacific Garbage Patch are entering the oceans. Work has been done to alter and treat polyethylene plastic to be added to cement mixtures. This is done to increase bearing capacity and ductility of concrete in addition to decreasing carbon emissions and plastic waste.

The purpose of this thesis is to gain exposure to current supply chain research topics through attendance of four seminars. The first portion of this paper includes summaries of each of the four seminars that I attended. These summaries are followed by an analysis of sustainable Styrofoam alternatives with a focus on factors deterring widespread use of these alternatives. This topic relates to the first seminar I attended, presented by Dr. Karen Donohue from the University of Minnesota. Specific areas of Donohue’s presentation — the shift toward e-commerce, and consolidated shipping with reduced packaging— sparked my interest in available alternatives for a popular, but unsustainable, packaging material: Styrofoam. I primarily considered journals and articles for the second portion of this thesis, but I also investigated these alternatives through visiting manufacturer websites discussing available products, production processes, and other available information.

The purpose of this thesis is to contextualise Hindsight, a sustainability-focused historically based city-simulation and resource management game built by the author. The game and game engine were coded from scratch using the C# programming language and the Unity game development suite of tools. The game focuses on the management of the city of London in two time periods, London from 1850 and the other set in 2050. Both versions of the city are divided into 21 zones, each of which can be managed by the player through the construction, upgrading, or destruction of various buildings within the zone. The player must manage both the city’s resources and the resources of the environment upon which the city depends in order to bring about a more sustainable future and bring the 2050-era version of the city back from the brink of environmental devastation. Along the way, the player must address the cultural views of the society they are managing to ensure their reforms will be accepted and can also see those views slowly change over time. The goal of the game is to provide an interactive learning experience for both the historical element of London and the importance of making sustainable choices.

Plasticizers are plastic additives used to enhance the physical properties of plastic and are ubiquitous in the environment. A class of plasticizer compounds called phthalate esters that are not fully eliminated in wastewater treatment facilities are relevant to the ecological health of downstream ecosystems and urban areas due to their ecotoxicity, tendency for soil accumulation, and the emerging concern about their effects on public health. However, plasticizer concentrations in a constructed wetland environment have rarely been studied in the United States, prompting the need for a method of plasticizer quantification in the Tres Rios Constructed Wetlands which are sustained by the effluent of the 91st Avenue Wastewater Treatment Plant in Phoenix, Arizona. The concentrations of four common plasticizer compounds (dimethyl: DMP, diethyl: DEP, di-n-butyl: DnBP, and bis(2-ethylhexyl): DEHP phthalate) at five sites across the wetland surface water were quantified using solid-phase extraction followed by gas chromatography coupled with mass spectrometry (GC/MS). The sampling period included four sample sets taken from March 2022 to September 2022, which gave temporal data in addition to spatial concentration data. Quantification and quality control were performed using internal standard calibration, replicate samples, and laboratory blanks. Higher molecular weight phthalates accumulated in the wetland surface water at significantly higher average concentrations than those of lower molecular weight at a 95% confidence level, ranging from 8 ng/L to 7349 ng/L and 4 ng/L to 27876 ng/L for DnBP and DEHP, respectively. Concentrations for dimethyl phthalate and diethyl phthalate were typically less than 50 ng/L and were often below the method detection limit. Average concentrations of DnBP and DEHP were significantly higher during periods of high temperatures and arid conditions. The spatial distribution of phthalates was analyzed. Most importantly, a method for successful ultra-trace quantification of plasticizers at Tres Rios was established. These results confirm the presence of plasticizers at Tres Rios and a significant seasonal increase in their surface water concentrations. The developed analytical procedure provides a solid foundation for the Wetlands Environmental Ecology Lab at ASU to further investigate plasticizers and contaminants of emerging concern and determine their ultimate fate through volatilization, sorption, photodegradation, hydrolysis, microbial biodegradation, and phytoremediation studies.

This thesis investigates the feasibility of using recycled ceramics as the aggregate in concrete, as an alternative to natural rock aggregates. The study evaluates the mechanical properties of concrete made with recycled ceramics and compares them with those of traditional concrete. The research involved laboratory experiments to determine compressive strength and displacement. The results show that the concrete made with recycled ceramics exhibited higher compressive strength and lower maximum displacement than traditional concrete, which means it acted more brittle. However, when the recycled ceramics were used to replace only 50% of the rock aggregate, the compressive strength decreased while the maximum displacement stayed the same, though the study concludes that a larger sample size is needed for more reliable results. Based on the findings, the thesis concludes that while the use of recycled ceramics in concrete may not be suitable for structural concrete, it could still have potential as a sustainable building material in non-structural applications.

This research explores the use of transformative urban scenarios and timelines as a planning tool for addressing future sustainability challenges in urban environments. The analysis comes from a set of scenarios that were explored through workshops conducted in 2019 in which Phoenix stakeholders developed timelines toward their visions of Phoenix 60 years into the future. To evaluate the pathways created in these timelines, we employed process tracing methodology to understand which causal mechanisms lead to certain phenomena. Or in other words, it helps us understand how changes happen. We converted the timelines into process tracing diagrams that categorized the relationship between actions, actors, and observable manifestations (OM’s) of change over time. To understand the relationship between these components, we then used a combination of inductive and deductive coding to categorize types of activities, actors, OM’s and sustainability topics and organized them into themes. This helped us to understand how city decision-makers and community leaders think sustainability and resilience transformation can and should occur. This thesis takes a closer look at one particular scenario, Some Like it Hot, which explores resilience to extreme heat. Through coding and analysis, we found trends, correlations, and missing pieces in the participants’ timeline. There are numerous overarching causal mechanisms throughout the scenario timeline. These trends offer insight into which activities and stakeholders are seen as significant drivers of sustainable transformation according to the workshop participants.

Valued as a $28 billion industry in 2021, the second-hand clothing industry, or thrifting industry, has been exploding (2020 Fashion Resale Market and Trend Report, 2020). This has been aided by a myriad of technological advancements, social movements, and economic factors. The goal of this thesis is to uncover consumer behaviors leading to this growth across behavioral, emotional, perceptual, and belief factors. Additionally, this thesis aims to provide strategic implications for marketing professionals, create recommendations for brands to successfully enter this industry and target consumers. In this study, a Qualtrics survey was distributed to students at Arizona State University. The results were analyzed through Microsoft Excel. The results showed that in order to be successful in this industry, brands should: emphasize sustainability in marketing, increase brand awareness, highlight feelings of pride in products, uniqueness, and affordability, mitigate feelings of poverty, low quality, and lack of variety, understand the perceptual differences in shopping versus thrifting, and take advantage of branded fashion.
