In 2018, the United States generated 37.4 million more U.S. tons of paper and cardboard material compared to in 1960 (EPA, 2020). As the United States produces a disproportionate amount of packaging waste every year when accounting for population size, it has become increasingly difficult to mitigate waste production, lessen the environmental impact of generating more paperboard materials, and move towards a more ethical circular economy. In efforts to adopt the principles of a green economy, deviate from the linear supply chain model, minimize packaging waste, and encourage more sustainable lifestyles, we developed a business centered around a circular, service based model called Room & Cardboard. Our initiative collects cardboard waste generated in and around the ASU community and repurposes it for dorm-style furniture available for students to rent throughout the school year. Using cardboard, we have built prototypes for two products (desk lamps and shoe racks) that are sturdy, visually pleasing, and recyclable. Our initiative helps to reduce cardboard packaging waste by upcycling cardboard waste into products that will increase the lifespan of the cardboard material. At the end of the product’s life span, in cases of severe damage, we will turn the product into a seed board made with blended cardboard paste that can then be used to plant a succulent we will make available to students to buy as dorm decor. The feedback on our initiative through online surveys and in-person tabling has generated enough traction for Dean Rendell of Barrett, the Honors College at Arizona State University to consider a test-drive of our products in the upcoming Fall semester.
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.
For the honors thesis project, a group of five individuals collaborated to design and implement a sustainable business in the ASU community. Kandi Society is a rising jewelry brand whose top priorities include giving recycled plastic a new purpose, philanthropy, and making a welcoming, creative environment for our customers. We designed the Eco-Bead with 3D CAD modeling and produced it through a process called plastic injection molding which is explained in detail in the final paper. Kandi Society instilled a positive impact on ASU students by igniting a sustainability spark and increasing interest in repurposing materials in the future.
Mining is a key component of both the Brazilian and Chilean economies and accounts for an outsized share of these countries’ exports. Yet, it is a common target for environmental criticism, especially due to its impacts on local populations and ecosystems. Brazil and Chile have adopted markedly different trade strategies over the past three decades, most notably with regards to their involvement in international trade agreements. This paper investigates how these differences in trade policy since 1990 have affected the sustainability of each country’s mining sector by identifying and comparing the channels through which free trade agreements influence the environmental impacts of resource extraction.

In 2019, the World Health Organization stated that climate change and air pollution is the greatest growing threat to humanity. With a world population of close to 8 billion people, the rate of population growth continues to increase nearly 1.05% each year. As the world population grows, carbon dioxide emissions and climate change continue to accelerate. By observing increasing concentrations of greenhouse gas emissions in the atmosphere, scientists have correlated that the Earth’s temperature is increasing at an average rate of 0.13 degrees Fahrenheit each decade. In an effort to mitigate and slow climate change engineers across the globe have been eagerly seeking solutions to fight this problem. A new form of carbon dioxide mitigation technology that has begun to gain traction in the last decade is known as direct air capture (DAC). Direct air capture works by removing excess atmospheric carbon dioxide from the air and repurposing it. The major challenge faced with DAC is not capturing the carbon dioxide but finding a useful way to reuse the post-capture carbon dioxide. As part of my undergraduate requirements, I was tasked to address this issue and create my own unique design for a DAC system. The design was to have three major goals: be 100% self-sufficient, have net zero carbon emissions, and successfully repurpose excess carbon dioxide into a sustainable and viable product. Arizona was chosen for the location of the system due to the large availability of sunlight. Additionally, the design was to utilize a protein rich hydrogen oxidizing bacteria (HOB) known as Cupriavidus Necator. By attaching a bioreactor to the DAC system, excess carbon dioxide will be directly converted into a dense protein biomass that will be used as food supplements. In addition, my system was designed to produce 1 ton (roughly 907.185 kg) of protein in a year. Lastly, by utilizing solar energy and an atmospheric water generator, the system will produce its own water and achieve the goal of being 100% self-sufficient.
