A Comparison Of The Efficacy Of Methane-Oxidizing Alternative Daily Landfill Covers And Policy Recommendations For Landfill Regulatory Agencies, Eric Lara

Master's Projects and Capstones

Methane (CH4) is a potent greenhouse gas (GHG) that has 28-36 times the greenhouse effect of carbon dioxide (CO2) over a 100-year timespan. Recent remote sensing research conducted by NASA Jet Propulsion Laboratory and Scientific Aviation has indicated that the working face of landfills are sectors of much higher methane emissions than previously considered. A working face location, which is the area of the landfill where daily waste is deposited, lacks the engineering controls present on the rest of the landfill. Controls such as gas collection and extraction wells and substantial covers to ensure surface integrity for methane leaks are …

Assessment Of The Environmental And Economic Impacts Of Fossil Fuel Subsidies, Evan Cobey

Undergraduate Theses and Capstone Projects

Renewable sources of energy remove dependence on fossil fuels. When renewable sources are adopted, they reduce damage to the environment from burning fossil fuels. Currently, fossil fuels are cheaper to produce, causing renewable energy to be used less. In the United States, fossil fuels receive heavy subsidies, keeping renewable energy in the periphery. This research explores the environmental and economic effects of subsidizing fossil fuels. Findings include that governments and citizens lose money when fossil fuels are subsidized. While subsidization initially makes them cheaper, they create expenses that are not factored into original costs, such as damage to human health …
