Description
The volume of end-of-life photovoltaic (PV) modules is increasing as the global PV market increases, and the global PV waste streams are expected to reach 250,000 metric tons by the end of 2020. If the recycling processes are not in place, there would be 60 million tons of end-of-life PV

The volume of end-of-life photovoltaic (PV) modules is increasing as the global PV market increases, and the global PV waste streams are expected to reach 250,000 metric tons by the end of 2020. If the recycling processes are not in place, there would be 60 million tons of end-of-life PV modules lying in the landfills by 2050, that may not become a not-so-sustainable way of sourcing energy since all PV modules could contain certain amount of toxic substances. Currently in the United States, PV modules are categorized as general waste and can be disposed in landfills. However, potential leaching of toxic chemicals and materials, if any, from broken end-of-life modules may pose health or environmental risks. There is no standard procedure to remove samples from PV modules for chemical toxicity testing in the Toxicity Characteristic Leaching Procedure (TCLP) laboratories as per EPA 1311 standard. The main objective of this thesis is to develop an unbiased sampling approach for the TCLP testing of PV modules. The TCLP testing was concentrated only for the laminate part of the modules, as they are already existing recycling technologies for the frame and junction box components of PV modules. Four different sample removal methods have been applied to the laminates of five different module manufacturers: coring approach, cell-cut approach, strip-cut approach, and hybrid approach. These removed samples were sent to two different TCLP laboratories, and TCLP results were tested for repeatability within a lab and reproducibility between the labs. The pros and cons of each sample removal method have been explored and the influence of sample removal methods on the variability of TCLP results has been discussed. To reduce the variability of TCLP results to an acceptable level, additional improvements in the coring approach, the best of the four tested options, are still needed.

This case study explores the institutions and governing strategies involved in the management of Rupa Lake in Kaski district in Western Nepal, particularly Rupa Lake Rehabilitation and Fishery Cooperative. Methods used for data collection include key informant interviews, household interviews, a focus group discussion and archival records. Institutions were examined for their effectiveness in sustaining natural and socioeconomic systems as perceived by community members. Based on a literature review and the results of the data collected, this thesis builds a case study highlighting Rupa Lake Rehabilitation and Fishery Cooperative's strategies for governing its local watershed and formulates a framework for commons institutions that aim to achieve sustainable outcomes. Based on findings, I argue that no single form of governance is a panacea for solving commons problems, governing strategies should be implemented on a case-by-case basis, and institutions should be involved at multiple levels and always include local input. Additionally, a sustainable institution should provide benefits to society that it can see, function democratically and with transparency, promote a biodiverse ecosystem, elevate marginalized groups, and collaborate with other institutions. These "clumsy" institutions create a series of complex interactions that are robust and adaptive to reflect the ever-changing systems they aim to govern.

In this paper, I analyze representations of nature in popular film, using the feminist / deconstructionist concept of a dualism to structure my critique. Using Val Plumwood’s analysis of the logical structure of dualism and the 5 ‘features of a dualism’ that she identifies, I critique 5 popular movies – Star Wars, Lord of the Rings, Brave, Grizzly Man, and Planet Earth – by locating within each of them one of the 5 features and explaining how the movie functions to reinforce the Nature/Culture dualism . By showing how the Nature/Culture dualism shapes and is shaped by popular cinema, I show how “Nature” is a social construct, created as part of this very dualism, and reified through popular culture. I conclude with the introduction of a number of ‘subversive’ pieces of visual art that undermine and actively deconstruct the Nature/Culture dualism and show to the viewer a more honest presentation of the non-human world.

Defines the concept of the arcology as conceived by architect Paolo Soleri. Arcology combines "architecture" and "ecology" and explores a visionary notion of a self-contained urban community that has agricultural, commercial, and residential facilities under one roof. Two real-world examples of these projects are explored: Arcosanti, AZ and Masdar City, Abu Dhabi, UAE. Key aspects of the arcology that could be applied to an existing urban fabric are identified, such as urban design fostering social interaction, reduction of automobile dependency, and a development pattern that combats sprawl. Through interviews with local representatives, a holistic approach to applying arcology concepts to the Phoenix Metro Area is devised.

In this project I analyze Paolo Soleri's concept of arcology \u2014 the combination of architecture and ecology \u2014 from a theoretical, symbolic, and physical perspective. I utilize these three viewpoints to determine what aspects of his theories are most effective for urban design. While his ideas are based on building "arcologies" from the ground up, I will be using the Phoenix Metropolitan area to determine how we could apply his ideas to existing cities without having to rebuild entirely. This past summer I participated in the 5-week construction workshop the Cosanti Foundation offers at the physical prototypical city of Arcosanti in Mayer, Arizona during which time I studied Soleri's work and participated in the construction of the city while also participating in the community dynamic there. I have found that while not all components of Soleri's theories translated well into Arcosanti, there are certainly some ideas that could be applied help to improve the City of Phoenix. I propose improvements to the pedestrian realm and an increase public space with an emphasis on utilizing the infrastructure and land that is already present for future development.

City planners often use bicycle friendly rating schemes as tools to guide them in their efforts to establish a bicycle community. However, the criteria and methodologies used vary from program to program and often do not encapsulate all of the necessary elements that comprise true bicycle friendliness. This report documents the important elements, strategies, and best practices that well-established Dutch, Danish, and German bike friendly cities exhibit to create a baseline standard for bicycle friendliness. Not all rating programs' criteria and methodologies align perfectly within this understanding of bicycle friendliness. City planners should use these programs as tools while keeping their limitations in consideration. The City of Tempe currently uses the League of American Bicyclists Bicycle Friendly Community program and BikeScore.com. By understanding the limitations associated with these programs, Tempe should move forward in their pursuit of bicycle friendliness by using multiple rating programs simultaneously and by looking at top-rated cities' strategies to enhance their infrastructure, network, urban form, and biking culture.

Social relationships are the single most factor that create joy in human lives. And yet, the ways we are building our cities and structuring our lives reduces our chances of interaction and increases isolation. Creating more public spaces may be a possible solution to this problem of declining social cohesion.

Social relationships are the single most factor that create joy in human lives. And yet, the ways we are building our cities and structuring our lives reduces our chances of interaction and increases isolation. Creating more public spaces may be a possible solution to this problem of declining social cohesion. Public spaces have been shown to improve rates of social cohesion and social interaction. They have also been show to have positive effects on physical health, local economies, the natural environment, reducing crime rates and psychological health. Creating public spaces in areas that are low-income or have limited amounts of space can be very challenging. This paper profiles options of community created spaces, space public spaces and temporary public spaces. All of which are options for low-income and limited space communities. The paper concludes with the summery of an active project to create a public space in such a community through a joint-use agreement.

Modern American environmental social movements have strived for a better world for nearly fifty years, pushing a philosophy of careful resource use and limited consumption as an alternative to the pollution and degradation that has so far accompanied global industrialization. The reach of these movements is broad and the topic they cover is one that aligns with the values and beliefs of many; it is thus quite confusing that they've been so unsuccessful. This thesis was a response to that apparent contradiction, exploring why movements have not been as successful as both they and the public initially desired. It began by defining what social movements are and how they emerge or find success, then provided a brief history of environmentalism in America, and the different successes and failures that occurred before and after the first Earth day in 1970. Finally, it explored some of the reasons environmentalism was unsuccessful, and found that while structural barriers like politics and business interests played a role in movement outcomes, the tactics of different groups were at least partially to blame. Once this was concluded, the author used the perspectives of different activists to propose ways to enhance the quality of current movements and allow them to continue to make progress well into the future. In order to expand the audience of this thesis, the author is also working on a children;s book that illustrates many of the important themes that he hopes to convey to the public. Though drafted, the book is incomplete as of the date that documents are due for Barrett review.

Midwestern cities are in decline, with shrinking populations and corresponding disinvestment. Many organizations and city governments are working on addressing the problem of vacancy while bringing these urban areas into the global economy. The EcoBlock Organization (EBO), a St. Louis-based non-profit, proposes block-level redevelopment as a method of fostering community and economic development while minimizing the impact on the environment. The EcoCode is a block-level form-based code describing the vision of the EBO and its implementation. This vision is centered around eight key design principles: energy, public health, social, urban design, water, transportation, resilience, and landscape. It manifests as an EcoBlock: a block of buildings surrounding a shared green space, connected by an energy grid and a shared geothermal loop with the goal of net-zero energy. The residences are a mix of building types for a variety of incomes and some building space will be designated for shared use, all physically reflecting the historic design of houses in the city in which the EcoBlock is implemented. Specifications like design, building placement, and mechanisms by which to strive towards net-zero energy and water will be determined in each location in which the EcoBlock is developed. The EcoCode describes the process and the desired outcome, providing a framework for this implementation.
The EcoCode resembles a typical form-based code in structure, but at a smaller geographic scale. General Provisions describes the context of the surrounding area that must be assessed before choosing to create an EcoBlock. Development and Adoption strategy explains the evolving role of the EBO and how the realization of this design is currently envisioned. Regulating Block, Block Development Standards, Building Envelope Standards, and Building Development Standards describe the detail that will need to be developed for the physical aspects of each block. Streetscape Standards describe the vision of the EBO as applicable to the streets surrounding an EcoBlock. Finally, the Sustainability Standards contain the contribution of each board member of the EBO with their unique expertise on implementing the design principles.
As a supplement to The EcoCode itself, this document contains three topics for case studies looking into the feasibility of the EcoBlock as a whole: shared space, net-zero energy, and mixed-income housing. Shared space development and management uses Montgomery Park in Boston to show the potential of community-based organization while warning against gentrification. The West Village campus of the University of California in Davis shows the technical possibility and the financial challenges of a net-zero community. Brogården, an affordable housing community in Sweden, demonstrates the possibility for decreasing energy consumption in public housing. Finally, Via Verde in New York City is an example of combining health, green space, and affordability in a mixed-income housing development. Though there is not yet an example of a fully implemented EcoBlock, these case studies speak to the challenges and the facilitators that the EBO will likely face.

As the move towards sustainable urbanism grows, understanding how the city has previously been envisioned and designed will be useful to moving forward. This work examines the legacy of urban design theories, what these theories have implied about what the city should be, and their sustainability consequences. Noticing three prominent urban design visions of the city, the technological city (as proposed in 1922 by Le Corbusier's Ville contemporaine and later in 1933 by his Ville Radieuse (The Radiant City), and in 1935 by Frank Lloyd Wright's' Broadacre City), the social city (as explored in 1961 by Jane Jacobs and in 1976 by Edward Relph of the University of Chicago), and the ecological city (as expounded upon in 1924 by both Lewis Mumford and in 1969 by Ian McHarg), I have newly applied the social-ecological-technical systems framework (SETS) to help classify and analyze these urban design theories and how they have mixed to create hybrid perspectives in more recent urban design theory. Lastly, I have proposed an urban design theory that envisions the sustainable city as an ongoing process. Hopefully, this vision that will hopefully be useful to the future of sustainable development in cities, as will a more organized understanding of urban design theories and their sustainability outcomes.
