Sustainable Materials Management and Circular Economy are both frameworks for considering the way we interact with the world's resources. Different organizations and institutions across the world have adopted one philosophy or the other. To some, there seems to be little overlap of the two, and to others, they are perceived as being interchangeable. This paper evaluates Sustainable Materials Management (SMM) and Circular Economy (CE) individually and in comparison to see how truly different these frameworks are from one another. This comparison is then extended into a theoretical walk-through of an SMM treatment of concrete pavement in contrast with a CE treatment. With concrete being a ubiquitous in the world's buildings and roads, as well as being a major constituent of Construction & Demolition waste generated, its analysis is applicable to a significant portion of the world's material flow. The ultimate test of differentiation between SMM and CE would ask: 1) If SMM principles guided action, would the outcomes be aligned with or at odds with CE principles? and conversely 2) If CE principles guided action, would the outcomes be aligned with or at odds with SMM principles? Using concrete pavement as an example, this paper seeks to determine whether or not Sustainable Materials Management and Circular Economy are simply different roads leading to the same destination.

The following Student Sustainability Consultant's Portfolio was created with the intention of being duplicated and utilized by Arizona State University (ASU) students to build their own Portfolio and to help prepare them for success after graduation. Student Consultants in GreenLight Solutions (GLS) are in a unique position to prepare themselves to create value for organizations while in school, and then continue to after graduation. When I enrolled in the School of Sustainability as an undergraduate transfer student I heard some constructive criticism from graduates of the school. Those students shared that while they had attained a great theoretical understanding of the science of sustainability, they lacked the ability to apply their knowledge in a practical way. They were struggling with finding work in their field because they could not communicate to employers how their knowledge was useful. They did not know how to apply their sustainability knowledge to create value for an organization. I did not want to have that same problem when I graduated. Enter GreenLight Solutions.

The United Nation's forecasts the World's population to grow to 9 billion by year 2050. This statistic, coupled with the fact that current organic food production yields average near 40% lower than conventionally grown crops, indicates that current methods of "sustainable" agriculture are sure to strip the planet of more wildlife habitat in order to feed so many mouths. Plus, erratic weather causing inconsistent crop production will leave vulnerable groups highly susceptible to famine. Agriculture today has a very complex supply chain that pulls resources from around the world to take to market. The Vertical Farm, LLC (TVF) seeks to change this reality and make 100% chemical free product, available locally to all major markets. The Vertical Farm, LLC is much different than a typical farm and operates on a soil-less hydroponic growing system. This system uses up to 95% less water and less than 50% of the fertilizer that an open-air organic farm would consume, by delivering all of the necessary nutrients directly to its crop's roots and recycling the solution in a closed loop system. TVF seeks to operate in unutilized warehouses and retail spaces, which will serve to control every aspects of the growing environment. This entails replacing sunlight with specially designed LED lights for horticulture applications and an HVAC system that creates the perfect growing conditions for plants to transpire. All of these capabilities translate into TVF being able to grow consistently year-round, regardless of weather, and produce quality local vegetables 30% faster than a conventional farm. In order to determine the economic feasibility of this business model, a prototype first had to be designed, which can be seen on Appendix A, B, & C. This system, designed in collaboration with University of Arizona's Controlled Environment Agricultural Center's Director, Gene Giacomelli PH. D., has determined that the roughly 1.75-acre system is capable of producing over 2.5 million pounds of lettuce every year. The footprint of the building includes all 3 major aspects of produce production, growing, harvesting, and packaging, and this vertically integrated business model allows The Vertical Farm to capture the most value, while taking its product to market. The net operating income of this prototype design is estimated to be 11.94%, with revenue in excess of $5.7 million and the largest costs being the LED lights and electricity. The Vertical Farm has mitigated its potentially largest cost, labor, by streamlining all processes of production in addition to employing the use of high-tech materials handling robots to transport crops within the facility. The Vertical Farm's production facility is not designed with human comfortability in mind (aisles are only 3' wide), but instead maximizes floor space utilization in order to produce as many pounds of product as possible. As a result, The Vertical Farm's prototype not only demonstrates the economic feasibility of indoor vertical farming today, but also gives significant merit to its growth potential to capture a portion of the $20 billion American vegetable market.

This research focused on how low-income communities in Ghana could convert Waste Vegetable Oil (WVO) into biodiesel to supplement their energy demands. The 2016 World Energy Outlook estimates that about 8 million Ghanaians do not have access to electricity while 82% of the population use biomass as cooking fuel. However, WVO is available in almost every home and is also largely produced by hotels and schools. There are over 2,700 registered hotels and more than 28,000 educational institutions from Basic to the Tertiary level. Currently, most WVOs are often discarded in open gutters or left to go rancid and later disposed of. Therefore, WVOs serve as cheap materials available in large quantities with a high potential for conversion into biodiesel and commercializing to support the economic needs of low-income communities. In 2013, a group of researchers at Kwame Nkrumah University of Science and Technology (KNUST) in Ghana estimated that the country could be producing between 82,361 and 85,904 tons of biodiesel from WVOs generated by hotels alone in 2015. Further analysis was also carried out to examine the Ghana National Biofuel Policy that was introduced in 2005 with support from the Ghana Energy Commission. Based on the information identified in the research, a set of recommendations were made to help the central government in promoting the biodiesel industry in Ghana, with a focus on low-income or farming communities. Lastly, a self-sustaining biodiesel production model with high potential for commercialization, was proposed to enable low-income communities to produce their own biodiesel from WVOs to meet their energy demands.

The purpose of this thesis is to compare ecolabeling to conservation easements for facilitating multi-use land between food production and conservation. Biodiversity has been on the decline as human agriculture uses more land. According to Encyclopedia Britannica “Half of the world’s habitable land (some 51 million square km [19.7 million square miles]) has been converted to agriculture, and some 77 percent of agricultural land (some 40 million square km [15.4 million square miles]) is used for grazing by cattle, sheep, goats, and other livestock. This massive conversion of forests, wetlands, grasslands, and other terrestrial ecosystems has produced a 60 percent decline (on average) in the number of vertebrates worldwide since 1970”(Rafferty 2010). The purpose of this paper is to explore ways individual landowners and private businesses can continue to operate profitably on their land while reversing the harmful loss to biodiversity observed in the past 50 years. Two of the most popular methods of achieving conservation on workable land are ecolabeling and conservation easements.

In arid environments such as Arizona, agricultural producers are burdened by constraints placed on them by inhospitable weather and limited access to water and fertile soil when attempting to grow produce. Farms in the arid Southwest often have to build greenhouses to overcome such constraints; however, such greenhouses may be relatively space, water, and pesticide intensive and often have demanding maintenance needs and overhead costs. In addition, many current agricultural practices exhaust land resources disparagingly, leading to irreversible environmental degradation. In an effort to improve agricultural production for those limited by weather and resource constraints while simultaneously increasing sustainability in land, resource and pesticide use, we have created Valleyponics, a hydroponic growth services company centered around creating a minimal farming footprint. The company uses a consultative services approach, leveraging NASA Veggie Growth System Technology to provide solutions to large businesses by automating their agricultural production processes and minimizing resource use year-round. Valleyponics aims to cultivate consultative partnerships which will allow our clients, their communities, and the environment to flourish.
