Description
Social entrepreneurship has received a great deal of attention in recent years. Scholars constantly debate of the meaning of the term and the direction of the field. This paper explores literature written between the years 2010 \u2014 2015 in an effort to understand the current state of social entrepreneurship and gain insight as to the direction it is headed. This paper looks at definitions, characteristics, geographical differences, legal designations, and major themes such as social enterprise, social innovation, & social value as well as the implications for performance measures in an attempt to understand the broad concept that is social entrepreneurship.

Description
A new class of entrepreneurs is emerging in China, who are using a business model approach to solve societal problems. A small but growing niche of these so called "social entrepreneurs" is attempting to address long standing problems in the agricultural sector stemming from the three agricultural issues of farmers, agriculture and rural areas. In order to understand what social entrepreneurship means in the Chinese context, the motivations behind it, and the opportunities and problems related specifically to agricultural sector, interviews were conducted with social entrepreneurs, research institutes, and social fostering organizations in multiple tier-one cities in mainland China. Results show that the concept of social enterprise is comprehended in a very different way in the Chinese context relative to the general usage of the term in the literature. Social enterprises in the agricultural sector are divided into categories of Community Supported Agriculture-based organic farms, farmers' markets, food educators and city farmers. This is a growing group of entrepreneurs who could be better supported on the basis of resources and protection by the government, law and policy, universities, and a united producer and consumer front.

Description
Bangladesh is facing one of the largest mass poisonings in human history with over 77 million people affected by contaminated water each and every day. Over the last few years, the 33 Buckets team has come together to help fulfill this clean water need through filtration, education, and an innovative distribution system to inspire and empower people in Bangladesh and across the world. To start this process, we are working with the Rahima Hoque Girls' school in the rural area of Raipura, Bangladesh to give girls access to clean water where they spend the most time. Through our assessment trip in May 2012, we were able to acquire technical data, community input, and partnerships necessary to move our project forward. Additionally, we realized that in many cases, including the Rahima Hoque school, water problems are not caused by a lack of technology, but rather a lack of utilization and maintenance long-term. To remedy this, 33 Buckets has identified a local filter to have installed at the school, and has designed a small-scale business focused on selling clean water in bulk to the surrounding community. Our price point and association with the Rahima Hoque Girls' school makes our solution sustainable. Plus, with the success of our first site, we see the potential to scale. We already have five nearby schools interested in working to implement similar water projects, and with over 100,000 schools in Bangladesh, many of which lack access to the right water systems, we have a huge opportunity to impact millions of lives. This thesis project describes our journey through this process. First, an introduction to our work prior to the assessment trip and through the ASU EPICS program is given. Second, we include quantitative and qualitative details regarding our May 2012 assessment trip to the Rahima Hoque school and Dhaka. Third, we recount some of the experiences we were able to participate in following the trip to Bangladesh, including the Dell Social Innovation Challenge. Fourth, we examine the technical filtration methods, business model development, and educational materials that will be used to implement our solution this summer. Finally, we include an Appendix with a variety of social venture competitions and applications that we have submitted over the past two years, in addition to other supplementary materials. These are excellent examples of our diligence and provide unique insight into the growth of our project.

Description
My thesis is an experiment on the influence of new methods and the public opinion. The compelling question is: If there are animal rescue operations that obtain the ability to function fully, increasing revenue and the number of animals they save daily, then why is euthanasia still utilized as a means of population control within other shelters? Instead of our shelters progressing in a direction that eliminates euthanasia, there is a number of recently innovated shelters that are uprising today with this dreadful sequence to fulfill vacated cages, once reached capacity— euthanize, replace the deceased, and repeat. This is a global issue that can be eliminated by mocking the success of no-kill shelters in existence today.

Description
Currently conventional Subtitle D landfills are the primary means of disposing of our waste in the United States. While this method of waste disposal aims at protecting the environment, it does so through the use of liners and caps that effectively freeze the breakdown of waste. Because this method can keep landfills active, and thus a potential groundwater threat for over a hundred years, I take an in depth look at the ability of bioreactor landfills to quickly stabilize waste. In the thesis I detail the current state of bioreactor landfill technologies, assessing the pros and cons of anaerobic and aerobic bioreactor technologies. Finally, with an industrial perspective, I conclude that moving on to bioreactor landfills as an alternative isn't as simple as it may first appear, and that it is a contextually specific solution that must be further refined before replacing current landfills.

Description
As part of the Founders’ lab program, this thesis explores a social venture idea whose concept is to connect the philanthropic community with individuals and organizations in need of funding a project relating to (Sustainable Development Goals) SDG indicators through a peer to peer donation platform. Through this platform, the philanthropic community will have the possibility to easily access a wide range of projects to support as well as underserved individuals and communities seeking for help, track their impact, donate in a complete transparent donation process, and automate donations through bank card rounds-up. This social venture idea has been named PhilanthroGo.

Characterization and Manipulation of Microbiomes From Arid Landfills for Improved Methane Production
Description
Environmentally harmful byproducts from solid waste’s decomposition, including methane (CH4) emissions, are managed through standardized landfill engineering and gas-capture mechanisms. Yet only a limited number of studies have analyzed the development and composition of Bacteria and Archaea involved in CH4 production from landfills. The objectives of this research were to compare microbiomes and bioactivity from CH4-producing communities in contrasting spatial areas of arid landfills and to tests a new technology to biostimulate CH4 production (methanogenesis) from solid waste under dynamic environmental conditions controlled in the laboratory. My hypothesis was that the diversity and abundance of methanogenic Archaea in municipal solid waste (MSW), or its leachate, play an important role on CH4 production partially attributed to the group’s wide hydrogen (H2) consumption capabilities. I tested this hypothesis by conducting complementary field observations and laboratory experiments. I describe niches of methanogenic Archaea in MSW leachate across defined areas within a single landfill, while demonstrating functional H2-dependent activity. To alleviate limited H2 bioavailability encountered in-situ, I present biostimulant feasibility and proof-of-concepts studies through the amendment of zero valent metals (ZVMs). My results demonstrate that older-aged MSW was minimally biostimulated for greater CH4 production relative to a control when exposed to iron (Fe0) or manganese (Mn0), due to highly discernable traits of soluble carbon, nitrogen, and unidentified fluorophores found in water extracts between young and old aged, starting MSW. Acetate and inhibitory H2 partial pressures accumulated in microcosms containing old-aged MSW. In a final experiment, repeated amendments of ZVMs to MSW in a 600 day mesocosm experiment mediated significantly higher CH4 concentrations and yields during the first of three ZVM injections. Fe0 and Mn0 experimental treatments at mesocosm-scale also highlighted accelerated development of seemingly important, but elusive Archaea including Methanobacteriaceae, a methane-producing family that is found in diverse environments. Also, prokaryotic classes including Candidatus Bathyarchaeota, an uncultured group commonly found in carbon-rich ecosystems, and Clostridia; All three taxa I identified as highly predictive in the time-dependent progression of MSW decomposition. Altogether, my experiments demonstrate the importance of H2 bioavailability on CH4 production and the consistent development of Methanobacteriaceae in productive MSW microbiomes.

Description
Plastic pollution is undoubtedly one of the most pressing challenges facing humanity today. Significant action is required in order to properly address this rapidly growing threat. The Circular Economy provides a promising model for solution design in terms of responsible consumption and production. Countdown: Circular Economy Solutions is an organization created by Jasmine Amoako-Agyei focused on addressing the threat of plastic pollution in the United States and Ghana, West Africa. The first part of this report will explain the severity of the global plastic pollution crisis and challenges with recycling. It will then present the Circular Economy as a viable model for a course of action. From there it will explain the efforts of Countdown: Circular Economy Solutions over the last two with a pathway forward. This venture leveraged the greater ASU ecosystem of resources such as Walton Sustainability Solutions, Precious Plastic ASU, the Luminosity Lab, Changemaker Central, Venture Devils, Engineering Projects in Community Service (ASU), Gary K. Herberger Young Scholars Academy, KNUST, and Ashesi D: Lab.

Description
Zero-Valent Metals (ZVM) are highly reactive materials and have been proved to be effective in contaminant reduction in soils and groundwater remediation. In fact, zero-Valent Iron (ZVI) has proven to be very effective in removing, particularly chlorinated organics, heavy metals, and odorous sulfides. Addition of ZVI has also been proved in enhancing the methane gas generation in anaerobic digestion of activated sludge. However, no studies have been conducted regarding the effect of ZVM stimulation to Municipal Solid Waste (MSW) degradation. Therefore, a collaborative study was developed to manipulate microbial activity in the landfill bioreactors to favor methane production by adding ZVMs. This study focuses on evaluating the effects of added ZVM on the leachate generated from replicated lab scale landfill bioreactors. The specific objective was to investigate the effects of ZVMs addition on the organic and inorganic pollutants in leachate. The hypothesis here evaluated was that adding ZVM including ZVI and Zero Valent Manganese (ZVMn) will enhance the removal rates of the organic pollutants present in the leachate, likely by a putative higher rate of microbial metabolism. Test with six (4.23 gallons) bioreactors assembled with MSW collected from the Salt River Landfill and Southwest Regional Landfill showed that under 5 grams /liter of ZVI and 0.625 grams/liter of ZVMn additions, no significant difference was observed in the pH and temperature data of the leachate generated from these reactors. The conductivity data suggested the steady rise across all reactors over the period of time. The removal efficiency of sCOD was highest (27.112 mg/lit/day) for the reactors added with ZVMn at the end of 150 days for bottom layer, however the removal rate was highest (16.955 mg/lit/day) for ZVI after the end of 150 days of the middle layer. Similar trends in the results was observed in TC analysis. HPLC study indicated the dominance of the concentration of heptanoate and isovalerate were leachate generated from the bottom layer across all reactors. Heptanoate continued to dominate in the ZVMn added leachate even after middle layer injection. IC analysis concluded the chloride was dominant in the leachate generated from all the reactors and there was a steady increase in the chloride content over the period of time. Along with chloride, fluoride, bromide, nitrate, nitrite, phosphate and sulfate were also detected in considerable concentrations. In the summary, the addition of the zero valent metals has proved to be efficient in removal of the organics present in the leachate.

Description
Often considered to be one of the most promising solutions in the fight against global poverty, “microfinance is a term used to describe financial services, such as loans, savings, insurance and fund transfers to entrepreneurs, small businesses and individuals who lack access to traditional baking services” (Kiva). With hundreds of organizations committed or partially committed to the facilitation of microfinance loans on a domestic and global scale, the way scholarly communities have ultimately decided to view this type of giving is narrow but optimistic. The trends associated with microfinancing show it to have a positive impact on both lenders and borrowers. The goal of this thesis is to bring a level of personal context to these trends with qualitative research from the stories of individuals who have participated in the facilitation of a microloan.
