A Comparison Of The Efficacy Of Methane-Oxidizing Alternative Daily Landfill Covers And Policy Recommendations For Landfill Regulatory Agencies, Eric Lara Dec 2020

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 …


Performance Assessment Of Solid State Anaerobic Digestion Of Poultry Litter, Mason Puckett May 2018

Performance Assessment Of Solid State Anaerobic Digestion Of Poultry Litter, Mason Puckett

Biological and Agricultural Engineering Undergraduate Honors Theses

The disposal of poultry litter can exert an economic and environmental burden to the agriculture community. As a result, it is desirable to reduce the amount of waste and recover resources from the waste. This study focuses on the construction and preliminary testing of a laboratory scale (20 L) solid state anaerobic digester (AD) fed with dry poultry litter. Glucose was added in addition to the poultry litter to achieve the appropriate C:N ratio to support the growth of anaerobic microorganisms. The AD was first fed every 4 days at 4 g VS/L/feeding for 24 days, rested (no feeding) for …
