Description
The objective for Under the Camper Shell was to build a prototype of a full living environment within the confines of a pickup truck bed and camper shell. The total volume available to work with is approximately 85ft3. This full living environment entails functioning systems for essential modern living, providing shelter and spaces for cooking, sleeping, eating, and sanitation. The project proved to be very challenging from the start. First, the livable space is extremely small, being only tall enough for one to sit up straight. The truck and camper shell were both borrowed items, so no modifications were allowed for either, e.g. drilling holes for mounting. The idea was to create a system that could be easily removed, transforming it from a camper to a utility truck. The systems developed for the living environment would be modular and transformative so to accommodate for different necessities when packing. The goal was to create a low-water system with sustainability in mind. Insulating the space was the largest challenge and the most rewarding, using body heat to warm the space and insulate from the elements. Comfort systems were made of high density foam cushions in sections to allow folding and stacking for different functions (sleeping, lounging, and sitting). Sanitation is necessary for healthy living and regular human function. A composting toilet was used for the design, lending to low-water usage and is sustainable over time. Saw dust would be necessary for its function, but upon composting, the unit will generate sufficient amounts of heat to act as a space heater. Showering serves the functions of exfoliation and ridding of bacteria, both of which bath wipes can accomplish, limiting massive volumes of water storage and waste. Storage systems were also designed for modularity. Hooks were installed the length of the bed for hanging or securing items as necessary. Some are available for hanging bags. A cabinetry rail also runs the length of the bed to allow movement of hard storage to accommodate different scenarios. The cooking method is called "sous-vide", a method of cooking food in air-tight bags submerged in hot water. The water is reusable for cooking and no dishes are necessary for serving. Overall, the prototype fulfilled its function as a full living environment with few improvements necessary for future use.

Description
Plastics make up a large proportion of solid waste that ends up in landfills and pollute ecosystems, and do not readily decompose. Composites from fungus mycelium are a recent and promising alternative to replace plastics. Mycelium is the root-like fibers from fungi that grow underground. When fed with woody biomass, the mycelium becomes a dense mass. From there, the mycelium is placed in mold to take its shape and grow. Once the growth process is done, the mycelium is baked to end the growth, thus making a mycelium brick. The woody biomass fed into the mycelium can include materials such as sawdust and pistachio shells, which are all cheap feedstock. In comparison to plastics, mycelium bricks are mostly biodegradable and eco-friendly. Mycelium bricks are resistant to water, fire, and mold and are also lightweight, sustainable, and affordable. Mycelium based materials are a viable option to replace less eco-friendly materials. This project aims to explore growth factors of mycelium and incorporate nanomaterials into mycelium bricks to achieve strong and sustainable materials, specifically for packaging materials. The purpose of integrating nanomaterials into mycelium bricks is to add further functionality such as conductivity, and to enhance properties such as mechanical strength.

Description
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.

Description
This paper outlines cumulative research on food deserts in relation to college students; namely, that there are communities classified as food deserts because significant numbers of the population lack access to grocery stores selling fresh produce or other goods normally called “healthy.” These areas are often also food swamps, or areas with intense access to sugar-dense, high-fat foods. Research as a whole suggests that three considerations primarily drive food insecurity for individuals caught in these food deserts: lack of access to a personal vehicle, low income or prohibitively expensive healthy foods, and personal education or culture (Wright et al., 2016). College students both fit into the geographical food deserts and are individuals who tend to have a worrying level of food insecurity (Kim, 2018). It is costly to make adjustments to entire environments to rid communities of food desert characteristics, and it is not always potent enough to end food insecurity or malnutrition; instead, it can be much more effective to focus on individuals within communities and help push cultures into a better direction. This project demonstrates that ASU students are experiencing food dissatisfaction and are in a food desert worthy of attention and action, and that students are motivated to see a solution. The solution that the paper focuses on is a food delivery system of fresh produce and foods for students, which addresses the three drivers of individual food deserts discussed by Wright et al. (2016).

Description
This thesis analyzes the process through which sustainability communication occurs between organizations and stakeholders. The lack of frameworks connecting research in the sustainability and communication fields highlights the need for a cohesive modelization of the sustainability communication process. This process forms the basis of the Action, Perception, Risk (APR) model, a framework that I have created. The APR model builds on existing sustainability and communication research to provide a practical illustration of the sustainability communication process, connecting the theoretical realm with the practitioner realm through implementable recommendations. This is achieved through a literature review and a case study of the American footwear company, Allbirds. Managerial implications are discussed and recommendations for effective sustainability communication are put forward.

Description
Our group examined the low rate of clothing utilization in the fashion industry. Fast fashion has contributed to this low rate of utilization, as well as the high amounts of textiles that end up in landfills. Our startup, Patchwork Apparel, was designed to address this problem. Our clothes were made with fabric scraps or donated textiles that would otherwise end up in landfills. The mission of our business was to develop trendy and sustainable apparel that helped to eliminate textile waste while staying on brand with current fashion trends.
