  • Techno-economic and Life-cycle Analyses of Glucosamine and Lipid Production from Marine Diatom Cyclotella sp.

    Creator:
    Xiang, Xuwen
    Abstract:
    Currently the production of biofuel from algae is not economically competitive with petroleum fuel. However, co-production of high-value products may be able to justify the cost of large-scale algae cultivation. The basic goal of this study is to develop a techno-economic analysis (TEA) and Life-cycle assessment (LCA) for the production...

  • Techno-economic analysis of algal lipid fuels

    Creator:
    Xiang, Xuwen
    Abstract:
    A techno-economic analysis (TEA) was performed to evaluate the technology, cost, and resource use for algal biofuel production based on today’s economics and technology. The basic goal of this study is to develop a model to calculate the mass and energy balances and costs to produce 10 million gal of...

  • 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...

  • Assessment of Decentralized Wastewater Treatment System- Potential Impact on Water Quality

    Creator:
    Chavan, Padmaja Ramesh
    Abstract:
    Watershed analysis is a method used to collectively characterize ecosystem elements present within a watershed. Wastewater flow and pollutant content help to define the appropriate wastewater treatment system necessary to treat the wastewater within the watershed. Watershed monitoring aids to investigate the potential contamination through analysis of surface waterbodies. Major...

  • Functional polymers and proteins at interfaces

    Creator:
    Schilke, Karl F.
    Abstract:
    Functional polymers and proteins at interfaces and surfaces are of fundamental importance for biomaterials, biocatalysis and microreactor applications. Candida antarctica lipase B immobilized on poly-DL-tryptophan tethers showed 30x higher specific activity in aqueous and non-aqueous media than the same enzyme adsorbed or covalently bound directly to the surface. An excess...

  • Techno-economic analysis of extraction curcumin from turmeric

    Creator:
    Kunta, Naveen
    Abstract:
    Curcumin is a yellow colored bioactive pigment present in the spice turmeric (Curcuma longa). It has been identified with antioxidant, anti-inflammatory, anticancer, antibacterial, antirheumatic, antidiabetic and antiviral properties. It is extensively used in nutraceutical, food and cosmetics industry. Fueled by its potential uses in research community and rise in awareness...

  • New application of crystalline cellulose in rubber composites

    Creator:
    Bai, Wen
    Abstract:
    Rubber without reinforcement has limited applications. The strength of reinforced rubber composites can be ten times stronger than that of unreinforced rubbers. Therefore, rubber composites are widely used in various applications ranging from automobile tires to seals, valves, and gaskets because of their excellent mechanical elastic properties. Silica and carbon...

  • Experimental approach for the determination of lignin modification by manganese peroxidase

    Creator:
    Goby, Jeffrey D.
    Abstract:
    Degradation of lignin to simpler compounds is desirable for removing residual lignin during paper manufacture and accessing biomass carbohydrates for biofuel production, among other purposes. Lignin transformation using enzymes found in white rot fungi, some of nature's most efficient lignin-degrading organisms, offers a more environmentally benign, selective, and possibly less...

  • Hydraulic characterization and modeling of the Talking Water Garden wetland for evaluation of nitrogen removal

    Creator:
    Huang, Tao
    Abstract:
    The purpose of this research is to hydraulically characterize an engineered wetland in Albany, Oregon. The wetland receives treated wastewater from both Albany Millersburg Water Reclamation Facility (AMWRF) and ATI Wah Chang. AMWRF's water is municipal waste water. ATI Wah Chang's water comes from its nearby metal processing plant. The...

  • The role of manganese peroxidase in biomass conversion technologies

    Creator:
    Yee, Kelsey L.
    Abstract:
    Currently, the technologies used to separate lignocellulosic biomass into its component parts (cellulose, hemicellulose, and lignin) and enzymatically hydrolyze the cellulose to glucose for conversion to ethanol could be improved economically and in terms of efficiency. A major impediment to utilizing the biomass is the presence of residual lignin. The...
