Description
Sustainability has been a growing topic since the 1970’s, but is truly taking shape today as society is beginning to understand the necessity of protecting our environment. Business organizations are following this ‘megatrend’ and are beginning to incorporate sustainable initiatives in their organizations from the inside out. The sports industry is no exception as they are extremely influential over the millions of fans that follow them, whom have a strong affiliation with their favorite team. The Arizona Diamondbacks understand this responsibility and seek to be a leader in their community by creating many sustainable initiatives within their organization and community. The current problem the organization faces, is that much of the community are not aware of their environmental commitment. This is in part due to a lack of marketing within the organization and to the Arizona valley. This project analyzes the sports industry’s commitment to sustainability and how the Arizona Diamondbacks compare to industry leaders. Included is a detailed marketing plan for the organization comprised of current initiatives and of new initiatives that the Diamondbacks could potentially carry out. The implementation of this proposal could deem extremely beneficial as it would strengthen their identity, unify their employees and engage fans, which will make them feel a deeper affiliation with the organization. The Diamondbacks have made a commitment to the environment, but it is time to deepen that commitment, set an example for people in the Valley and in turn, spark social change.

Description
Ethanol is a widely used biofuel in the United States that is typically produced through the fermentation of biomass feedstocks. Demand for ethanol has grown significantly from 2000 to 2015 chiefly due to a desire to increase energy independence and reduce the emissions of greenhouse gases associated with transportation. As demand grows, new ethanol plants must be developed in order for supply to meet demand. This report covers some of the major considerations in developing these new plants such as the type of biomass used, feed treatment process, and product separation and investigates their effect on the economic viability and environmental benefits of the ethanol produced. The dry grind process for producing ethanol from corn, the most common method of production, is examined in greater detail. Analysis indicates that this process currently has the highest capacity for production and profitability but limited effect on greenhouse gas emissions compared to less common alternatives.

Description
Calcium hydroxide carbonation processes were studied to investigate the potential for abiotic soil improvement. Different mixtures of common soil constituents such as sand, clay, and granite were mixed with a calcium hydroxide slurry and carbonated at approximately 860 psi. While the carbonation was successful and calcite formation was strong on sample exteriors, a 4 mm passivating boundary layer effect was observed, impeding the carbonation process at the center. XRD analysis was used to characterize the extent of carbonation, indicating extremely poor carbonation and therefore CO2 penetration inside the visible boundary. The depth of the passivating layer was found to be independent of both time and choice of aggregate. Less than adequate strength was developed in carbonated trials due to formation of small, weakly-connected crystals, shown with SEM analysis. Additional research, especially in situ analysis with thermogravimetric analysis would be useful to determine the causation of poor carbonation performance. This technology has great potential to substitute for certain Portland cement applications if these issues can be addressed.

Description
This paper explores multidisciplinary curricula, services, and experiential learning in higher education on sustainability. Researchers attempt to understand sustainability as a formalized degree program, what frameworks and techniques are used to improve new disciplines, and how Arizona State University's School of Sustainability (SOS) improves sustainability education in higher learning. Secondary research includes a discussion on the history of sustainability as a discipline, the university as a social system, the role of university administration, the roles of professors and students, benchmarking and process improvement for curriculum development, and methods to bridge epistemologies in SOS. The paper presents findings from a study of the SOS undergraduate student experience that used focus groups to gather qualitative data and statistical analysis to analyze that data quantitatively. Study findings indicate that that measuring student perception of SOS's academic services, and understanding the social system of the university, helps administration, faculty, and students collaborate more effectively to enhance learning experiences.

Description
In 2016, in the United States alone, the cosmetics industry made an estimated 62.46 billion dollars in revenue (Revenue of the Cosmetic Industry in the U.S. 2002-2016 | Forecast). With a consistent increase in sales in the last several years, the industry has reached continued success even during times of hardship, such as the Great Recession of 2008. The use of Corporate Social Responsibility (CSR), external campaigns, and thoughtful packaging and ingredients resonates with targeted consumers. This has served as an effective strategy to maintain growth in the industry. Cosmetic companies promote their brand image using these sustainability tactics, but there seems to be a lack of transparency in this unregulated industry. The purpose of this thesis is to determine if the cosmetics industry is a good steward of the sustainability movement. Important terms and concepts relating to the industry will be discussed, then an analysis of sustainability focused cosmetic brands will be provided, which highlights the extent to which these brands engage in activities that promote sustainability. This is followed by an application of findings to a company that could benefit from using such practices. Overall, the analysis of the different brands proved to be shocking and disappointing. This is due to the sheer amount that scored very poorly based on the sustainability criteria developed. The cosmetics industry is too inconsistent and too unregulated to truly act as a good steward for sustainability. Though some companies in the industry succeed, these accomplishments are not consistent across all cosmetic companies. Hence, the cosmetics industry as a good steward for sustainability can only be as strong as its weakest link.

Description
Although the Leadership Scholarship Program has seen successful recruiting processes throughout changes in leadership of the program; the organization expressed a need for major overhaul to reevaluate the decisions of the process and to establish backing for those decisions. By asking current and alumni members of the program about what they would like to see in a future member of the program as well as which parts of the process they found most important, the qualities of a future member of the program could be established and weighted. The goals of the reevaluation were to help eliminate bias, discrepancies between applications with extremely different uncontrollable factors, define points of discrepancies, and establish organizational sustainability while achieving a 100% acceptance rate from offered students. Each of these goals was achieved through methods outlined in the LSP Selection Process Manual that was written as a result of this reevaluation. The manual also outlines ways to improve the process going forward.

Description
Currently, approximately 40% of the world’s electricity is generated from coal and coal power plants are one of the major sources of greenhouse gases accounting for a third of all CO2 emissions. The Integrated Gasification Combined Cycle (IGCC) has been shown to provide an increase in plant efficiency compared to traditional coal-based power generation processes resulting in a reduction of greenhouse gas emissions. The goal of this project was to analyze the performance of a new SNDC ceramic-carbonate dual-phase membrane for CO2 separation. The chemical formula for the SNDC-carbonate membrane was Sm0.075Nd0.075Ce0.85O1.925. This project also focused on the use of this membrane for pre-combustion CO2 capture coupled with a water gas shift (WGS) reaction for a 1000 MW power plant. The addition of this membrane to the traditional IGCC process provides a purer H2 stream for combustion in the gas turbine and results in lower operating costs and increased efficiencies for the plant. At 900 °C the CO2 flux and permeance of the SNDC-carbonate membrane were 0.65 mL/cm2•min and 1.0×10-7 mol/m2•s•Pa, respectively. Detailed in this report are the following: background regarding CO2 separation membranes and IGCC power plants, SNDC tubular membrane preparation and characterization, IGCC with membrane reactor plant design, process heat and mass balance, and plant cost estimations.

Description
p-Coumaric acid is used in the food, pharmaceutical, and cosmetic industries due to its versatile properties. While prevalent in nature, harvesting the compound from natural sources is inefficient, requiring large quantities of producing crops and numerous extraction and purification steps. Thus, the large-scale production of the compound is both difficult and costly. This research aims to produce p-coumarate directly from renewable and sustainable glucose using a co-culture of Yeast and E. Coli. Methods used in this study include: designing optimal media for mixed-species microbial growth, genetically engineering both strains to build the production pathway with maximum yield, and analyzing the presence of p-Coumarate and its pathway intermediates using High Performance Liquid Chromatography (HPLC). To date, the results of this project include successful integration of C4H activity into the yeast strain BY4741 ∆FDC1, yielding a strain that completely consumed trans-cinnamate (initial concentration of 50 mg/L) and produced ~56 mg/L p-coumarate, a resting cell assay of the co-culture that produced 0.23 mM p-coumarate from an initial L-Phenylalanine concentration of 1.14 mM, and toxicity tests that confirmed the toxicity of trans-cinnamate to yeast for concentrations above ~50 mg/L. The hope for this project is to create a feasible method for producing p-Coumarate sustainably.

Description
In the pursuit of sustainable sources of energy that do less harm to the environment, numerous technologies have been developed to reduce carbon emissions in the atmosphere. The implementation of carbon capture and storage systems (CCS) has played a crucial role in reducing CO2 emissions, but depleting storage reserves and ever-increasing costs of sequestrating captured CO2 has prompted the idea of utilizing CO2 as soon as it is produced (i.e. carbon capture and utilization, or CCU) and storing any remaining amounts. This project analyzes the cost of implementing a delafossite CuFeO2 backed CCU system for the average US coal-burning power plant with respect to current amounts of CO2 captured. Beyond comparing annual maintenance costs of CCU and CCS systems, the project extends previous work done on direct CO2 conversion to liquid hydrocarbons by providing a protocol for determining how the presence of NO affects the products formed during pure CO2 hydrogenation. Overall, the goal is to gauge the applicability of CCU systems to power plants with a sub 10-year lifespan left, whilst observing the potential revenue that can be potentially generated from CCU implementation. Under current energy costs ($0.12 per kWh), a delafossite CuFeO2 supported CCU system would generate over $729 thousand in profit for an average sized supercritical pulverized coal power (SCPC) plants selling diesel fuel created from CO2 hydrogenation. This amount far exceeds the cost of storing captured CO2 and suggests that CCU systems can be profitable for SCPC power plants that intend to burn coal until 2025.
