  • Life cycle assessment of algal biofuels

    Creator:
    Kirby, Bryan L.
    Abstract:
    This thesis consists of three studies to better understand the environmental sustainability potential for algal-based biofuels. Initially, a comparison of recent life cycle assessments (LCA) of theoretical full-scale algal biofuel facilities was developed. These studies include varying boundaries and scope, functional units, and technology maturity assumptions. The comparison converted results...

  • Alternative design considerations for a wave energy converter : a sustainability approach

    Creator:
    Collins, Erin
    Abstract:
    As the negative impacts of a fossil fueled electricity market are becoming more prevalent and destructive, the necessity for alternative energy techniques increases as well. However, before commercial implementation is underway, these alternatives must be assessed from three important perspectives: environmentally, economically, and socially, which are known as the three...

  • Light-frame versus timber frame : a study in quantifying the differences

    Creator:
    Malone, Brian P.
    Abstract:
    The objective of this study was to compare light wood framing and traditional timber framing quantitatively through environmental impact assessment and load path analysis. This research was inspired by a traditional timber frame structure constructed in Vermont in 2011, and the design of structures considered within reflect the general characteristics...

  • Investigation of the environmental impact of wind energy and supplemental energy systems using a life cycle approach

    Creator:
    Prempreeda, Preedanood
    Abstract:
    Wind energy is a promising alternative energy source due to its environmental, economic, and social benefits and, as such, has garnered public support and government incentives for its development and implementation. With the growing number of wind parks in Oregon, a life cycle assessment (LCA) study for a representative new...

  • Modeling innovativeness in consumer products with the influence of environmental sustainability

    Creator:
    Gilchrist, Brady
    Abstract:
    This thesis is the result of two research publications, which together form a framework for the evaluation of product innovativeness with potential future applications to early design. Innovation is a challenging concept to quantify. Experts seemingly have a grasp of what innovation is when they see it, however this evaluation...

  • A methodology to reduce the strain on hydro turbines using advanced life extending control of multiple energy storage systems

    Creator:
    Brosig, Sean G.
    Abstract:
    Over the last 20 years, there has been rapid growth in the amount of installed wind power in the Pacific Northwest, specifically in the Columbia River Gorge. The variable and non-dispatchable nature of this resource requires that it be balanced in some form by other sources on the grid. In...

  • Process-based modeling for cradle-to-gate energy and carbon footprint reduction in product design

    Creator:
    Alsaffar, Ahmed J.
    Abstract:
    Interest in accounting for environmental impacts of products, processes, and systems during the design phase is increasing. Numerous studies have undertaken investigations for reducing environmental impacts across the product life cycle. Efforts have also been launched to quantify such impacts more accurately. Life cycle energy consumption and carbon footprint are...

  • Slow fashion development : a model for sustainability

    Creator:
    Tobeck, Matthew R.
    Abstract:
    The purpose of this study was to develop a slow fashion design model using the house of quality model (HOQ) to provide designers an opportunity to improve the overall sustainability of an apparel product. Slow fashion is based on the slow food movement that supports the consumption of food that...

  • To restore what once was : a mixed methods approach to understanding the shoe repair transaction

    Creator:
    Giulietti, Michael P.
    Abstract:
    The shoe repair transaction, as it occurs in the 5000 or so remaining shoe repair shops in the United States, is currently unexamined in academic literature for the significance it holds for either shoe repairers or their customers. Making use of both quantitative and qualitative methods of data collection, this...

  • Evaluating the Sustainability of an Advanced Biofuel Using Attributional and Consequential Life Cycle Assessments

    Creator:
    McDaniel, Allexander M.
    Abstract:
    Attributional and consequential life cycle assessments are useful in evaluating the environmental impacts of a process, product, or decision. Both types of life cycle assessments differ however in their scope and their ability to answer specific questions. In order to fully understand and compare the environmental impacts of a sugarcane...
