This thesis project has been conducted in accordance with The Founder’s Lab initiative which is sponsored by the W. P. Carey School of Business. This program groups three students together and tasks them with creating a business idea, conducting the necessary research to bring the concept to life, and exploring different aspects of business, with the end goal of gaining traction. The product we were given to work through this process with was Hot Head, an engineering capstone project concept. The Hot Head product is a sustainable and innovative solution to the water waste issue we find is very prominent in the United States. In order to bring the Hot Head idea to life, we were tasked with doing research on topics ranging from the Hot Head life cycle to finding plausible personas who may have an interest in the Hot Head product. This paper outlines the journey to gaining traction via a marketing campaign and exposure of our brand on several platforms, with a specific interest in website traffic. Our research scope comes from mainly primary sources like gathering opinions of potential buyers by sending out surveys and hosting focus groups. The paper concludes with some possible future steps that could be taken if this project were to be continued.

Currently, recycling is a major issue found throughout the world; however, one of the main issues, small format recycling, is still yet to be solved. The main objective of this paper is to discuss the issues surrounding recycling in general and more specifically small format recycling in order to develop a solution that can solve the problem. Working with InnovationSpace and people in industry, interviews were conducted in order to determine the best course of action to address the need of the sponsor, The Sustainability Consortium. After extensive research and interviews, it was determined that implementing a new MRF attachment to circulate small format back to the main residual stream would be the best course of action. This attachment would be modular for a MRF and could be implemented in order to gather more material while also producing higher quality recycled goods. This has major implications for the recycling industry and could help in making recycling profitable once again.

The possibility of creating inorganic/organic hybrid materials has yet to be fully explored within geopolymer research. Using PDMS as an organic precursor, the surface of sodium and potassium geopolymers of varying precursor composition were functionalized with degraded PDMS oligomers. Both types of geopolymer yielded hydrophobic materials with BET surface area of 0.6475 m2/g and 4.342 m2/g for sodium and potassium geopolymer, respectively. Each respective material also had an oil capacity of 74.75 ± 4.06 weight% and 134.19 ± 4.89 weight%. X-ray diffraction analysis demonstrated that the PDMS functionalized sodium geopolymers had similar crystal structures that matched references for zeolite A and sodalite. The potassium geopolymers were amorphous, but showed consistency in diffraction patterns across different compositions.

Given their manufacturing versatility, plastics have fundamentally changed commercial consumerism. Unfortunately, two of the largest drawbacks to current plastics on the market is their dependency on fossil fuels and their lack of circular recyclability. In this paper, the focus will be on the latter issue. Circular recyclability can be described as the idea of minimizing waste through its reformation back into a commodity. Currently, the primary method of recycling plastics, mechanical recycling, can only be achieved through melting and reshaping plastic for reuse. A significant drawback to this method is the reduction in chain molecular weight and subsequent loss of mechanical integrity through multiple reheating cycles. Chemical recycling provides an alternative where the polymer is broken down through chemically reactive sites, allowing the material to be recycled a theoretically infinite number of times and maintain its mechanical properties. Polyethylene, one of the largest classes of industrially produced plastic, does not have any commercially relevant chemically recyclable derivatives. The structure of polyethylene is primarily composed of long, nonpolar hydrocarbon chains that provide the material’s signature tough property. To make a material that can be depolymerizable for chemical recycling, polar ester functional groups must be added throughout the chain, allowing for chain scission by hydrolysis. Unfortunately, while the incorporation of ester functionality into polyethylene has been studied previously, material strength decreases as a result of this modification, sacrificing the integrity of the final product. Herein, I propose the incorporation of nucleobase pairings into the ester-containing polyethylene, which will add supramolecular hydrogen bonding reinforcements to improve the mechanical performance while maintaining chemical recyclability. This addition to the polyethylene backbone will be achieved by the synthesis of a ureido cytosine (UCy) diol, which contains 4 complementary hydrogen bonding sites for enhanced intermolecular forces between polyethylene chains.

Plastic consumption has reached astronomical amounts. The issue is the single-use plastics that continue to harm the environment, degrading into microplastics that find their way into our environment. Finding sustainable, reliable, and safe methods to break down plastics is a complex but valuable endeavor. This research aims to assess the viability of using biochar as a catalyst to break down polyethylene terephthalate (PET) plastics under hydrothermal liquefaction conditions. PET is most commonly found in single-use plastic water bottles. Using glycolysis as the reaction, biochar is added and assessed based on yield and time duration of the reaction. This research suggests that temperatures of 300℃ and relatively short experimental times were enough to see the complete conversion of PET through glycolysis. Further research is necessary to determine the effectiveness of biochar as a catalyst and the potential of process industrialization to begin reducing plastic overflow.

The purpose of this thesis was to understand the importance of supply chain visibility (SCV) and to provide an analysis of the technology available for achieving SCV. Historical events where companies lacked efficient SCV were assessed to understand how errors in the supply chain can have detrimental effects on a company and their reputation. Environmental, social, and governance standards within the supply chain were defined along with the importance of meeting the legal and consumer expectations of a supply chain. There are many different organizations dedicated to helping companies meet ESG standards to achieve ethical, sustainable supply chains. Examples such as the Responsible Business Association and the Organization for Economic Co-Operation and Development were considered. A government solution to SCV, called the Freight Logistics Optimization Works Initiative, considered the importance of data sharing for large companies with complex supply chains, and this solution was assessed for understanding. Current companies and technologies available to achieve SCV were examined for understanding as to how the issue of SCV is currently addressed in the industry. A case study on the company Moses Lake Industries looked at how their complicated chemical manufacturing supply chain has adapted to achieve SCV. This included understanding supplier location, manufacturing processes, and risks. Future technologies that are currently being developed which could further benefit the supply chain industry were considered. Other future considerations, such as the movement of manufacturing out of high risk areas and the need for centralization of SCV solution, were also discussed.

This thesis analyzed Canon GPR-30 Black Standard Yield Toner in hopes to gain better understanding of the additives and plastic used in a popular photocopier toner formulation. By analyzing the toner’s composition from the perspective of its recyclability and potential to be manufactured using recycled plastic, this thesis hoped to fill a gap in current literature regarding how toner fits into a circular economy. While the analysis of the selected toner was ultimately inconclusive, three hypotheses about the toner’s composition are put forth based upon data from differential scanning calorimetry (DSC), solubility analysis, and Fourier Transform Infrared (FTIR) spectroscopy experimentation. It is hypothesized that the toner is most likely composed of either polymethyl methacrylate (PMMA) or polyethylene terephthalate (PET). Both of these polymers have characteristic FTIR peaks that were exhibited in the toner spectra and both polymers exhibit similar solubility behavior to toner samples. However, the glass transition temperature and melting temperature of the toner sampled were 58℃ and 74.5℃ respectively, both of which are much lower than that of PMMA and PET. Thus, a third hypothesis that would better support DSC findings is that the toner is primarily composed of nylon 6,6. While DSC data best matches this polymer, FTIR data seems to rule out nylon 6,6 as an option because its characteristic peaks were not found in experimental data. Thus, the Canon GPR-30 Black Standard Yield Toner is probably made from either PMMA or PET. Both PMMA and PET are 100% recyclable plastics which are commonly repurposed at recycling facilities, however, unknowns regarding toner additives make it difficult to determine how this toner would be recycled. If the printing industry hopes to move towards a circular economy in which plastic can be recycled to use towards toner manufacturing and toner can be “unprinted” from paper to be recycled into new toner, it is likely that monetary incentives or government regulations will need to be introduced to promote the sharing of toner formulations for recycling purposes.

This honors thesis report aims to propose a sustainable long-term solution for providing off-grid solar energy to rural communities that lack the necessary grid energy infrastructure. With this in mind, we aim to establish the framework and documentation for people to be able to build and maintain their own off-grid solar power systems. Due to recent pushes for clean energy both nationwide and statewide, the team will discuss the current renewable energy market and the incentives to justify the future growth potential of residential solar energy systems, which includes off-grid or remote solar. This discussion will include comparing pre-built solar systems currently offered for purchase against the proposed design outlined in this report. Notably, the outlined design has been made with an emphasis on system sustainability, low initial cost, reliability, ease of manufacturing/maintenance, and material selection. Lastly, the team will discuss the project’s approach to documentation with a user manual draft to ensure the system's long-term sustainability and troubleshooting. Although the efforts of this project have increased over time, this project remains active within the ASU EWB chapter, meaning that not all aspects described throughout this report are fully complete. The Native American community of Shonto, Arizona, will be used as an example to understand a rural community's needs for designing a solar panel system that provides sufficient energy for a single household. The project was completed in collaboration with Arizona State University’s Engineering Projects In Community Service (EPICS) program and Engineers Without Borders (EWB) chapter. Both these organizations aim to connect ASU students to the professional mentors and resources they need to design and implement low-cost, small-scale, easily replicated, and sustainable engineering projects.
