Biochar Amended Biological Systems For Enhanced Landfill Leachate And Lignocellulosic Banana Waste Treatment, Xia Yang
USF Tampa Graduate Theses and Dissertations
Biochar is an inexpensive and environmentally friendly carbonaceous pyrolysis byproduct with a high surface area, pore volume, and adsorption capacities for inorganic and organic compounds. The goal of this dissertation is to evaluate the feasibility of biochar application in biological treatment systems for enhanced waste management. Three major objectives guided this research to provide a compressive understanding of biochar enhancement effects on biological treatment systems for contaminant removal, energy recovery, and environmental impacts as well as essential factors influencing biochar production and properties.
In Objective 1 a low-cost hybrid Constructed Wetland (CW) system modified with biochar/zeolite was developed for enhanced …

A laboratory study was conducted to measure the effects of diet, moisture, temperature, and time on greenhouse gas (GHG) emissions from feedlot surface materials (FSM). The FSM were collected from open-lot pens where beef cattle were fed either a dry-rolled corn (DRC) diet containing no wet distillers grains with solubles (WDGS) or a DRC diet containing 35% WDGS. The FSM were collected, air-dried or mixed with 3.0 L of water to represent dry or wet conditions, and then incubated at temperatures of 5°C, 15°C, 25°C, or 35°C. Static flux chambers were used to quantify GHG emissions over a 14-day period. …
