Food Waste Storage Gaseous Emissions Detection And Quantification Using Infrared Spectroscopy, Ryley A. Burton-Tauzer

Cal Poly Humboldt theses and projects

A growing interest in sustainable waste management and the implementation of new policies have prompted a shift towards alternative resource recovery methods for organic waste, including food waste. To effectively assess alternative food waste treatment scenarios, it is important to evaluate the life cycle impacts associated with each scenario. The storage phase of food waste, encompassing its accumulation in kitchens, and storage in bins for collection and transportation, has been overlooked as a source of greenhouse gases in previous studies. This investigation aimed to identify the greenhouse gases emitted during the initial five-day period of low-oxygen storage. An open dynamic …

Date Palm Waste Pyrolysis Into Biochar For Carbon Dioxide Adsorption, Imen Ben Salem, Mariam Badawi Saleh, Jibran Iqbal, Maisa El Gamal, Suhaib Hameed

All Works

Mitigation of CO2 is a very popular research currently, it is ultimately beneficial to find new ways that are sustainable, low cost and gas emission friendly. Therefore, with biochar’s characteristics and properties it has great potential to be used as a CO2 capture and storage media. The objectives of reducing palm waste by using the low-cost, sustainable method for reducing and storing CO2, characterize the DPL biochar through FTIR, XRD, SEM, EDX, and then evaluate the efficiency of the date palm leaf waste biochar in adsorbing CO2 through the Gas–Solid analyzer technology. Date palm leaf was set in pyrolysis process …

Effects Of Residue Removal And Tillage On Greenhouse Gas Emissions In Continuous Corn Systems As Simulated With Rzwqm2, Haomiao Cheng, Kexin Shu, Zhiming Qi, Liwang Ma, Virginia L. Jin, Youjia Li, Marty R. Schmer, Brian J. Wienhold, Shaoyuan Feng

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Agricultural production is a major source of carbon dioxide (CO2) and nitrous oxide (N2O) globally. The effects of conservation practices on soil CO2 and N2O emissions remain a high degree of uncertainty. In this study, soil CO2 and N2O emissions under different residue and tillage practices in an irrigated, continuous corn system, were investigated using the Root Zone Water Quality Model (RZWQM2). Combinations of no/high stover removal (NR and HR, respectively) and no-till/conventional tillage (NT and CT, respectively) field experiments were tested over the four crop-years (Apr. 2011–Apr. 2015). The model was calibrated using the NRCT, and validated with other …

Variables Governing The Initial Stages Of The Synergisms Of Ultrasonic Treatment Of Biochar In Water Saturated With Carbon Dioxide, Adedapo Reuben Adeniyi

Electronic Theses and Dissertations

This work investigates the initial stage of the synergistic processes of acoustic treatment of biochar in water saturated with CO2 (AIChE Journal, 2014;60:1054-1065). Treatments with switchgrass and miscanthus biochars have been conducted to examine the effects of acoustic intensity, biochar/H2O ratio, CO2 concentrations of the solution, and that in the headspace above the solution. The changes in biochars’ heating values, carbon and hydrogen contents, internal surface area, and pore size distribution have significant technological implications and are the focal points of this study. The miscanthus and switchgrass biochars were produced via pyrolysis process at 700 oC and 550 oC, respectively. …

Greenhouse Gas Emissions From Beef Feedlot Surface Materials As Affected By Diet, Moisture, Temperature, And Time, Bryan L. Woodbury, John E. Gilley, David B. Parker, Bobbi S. Stomer

Biological Systems Engineering: Papers and Publications

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. …

Carbon Abatement And Emissions Associated With The Gasification Of Walnut Shells For Bioenergy And Biochar Production, Engil Isadora Pujol Pereira, Emma C. Suddick, Johan Six

School of Earth, Environmental, and Marine Sciences Faculty Publications and Presentations

By converting biomass residue to biochar, we could generate power cleanly and sequester carbon resulting in overall greenhouse gas emissions (GHG) savings when compared to typical fossil fuel usage and waste disposal. We estimated the carbon dioxide (CO2) abatements and emissions associated to the concurrent production of bioenergy and biochar through biomass gasification in an organic walnut farm and processing facility in California, USA. We accounted for (i) avoided-CO2 emissions from displaced grid electricity by bioenergy; (ii) CO2 emissions from farm machinery used for soil amendment of biochar; (iii) CO2 sequestered in the soil through stable biochar-C; and (iv) direct …

Soil Greenhouse Gas Emissions In Response To Corn Stover Removal And Tillage Management Across The Us Corn Belt, Virginia L. Jin, John M. Baker, Jane M.F. Johnson, Douglas Karlen, R. Michael Lehman, Shannon L. Osborne, Thomas J. Sauer, Diane E. Stott, Gary E. Varvel, Rodney T. Venterea, Marty R. Schmer, Brian J. Wienhold

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

In-field measurements of direct soil greenhouse gas (GHG) emissions provide critical data for quantifying the net energy efficiency and economic feasibility of crop residue based bioenergy production systems. A major challenge to such assessments has been the paucity of field studies addressing the effects of crop residue removal and associated best practices for soil management (i.e., conservation tillage) on soil emissions of carbon dioxide (CO₂), nitrous oxide (N₂O), and methane (CH₄). This regional survey summarizes soil GHG emissions from nine maize production systems evaluating different levels of corn stover removal under conventional or conservation …

International Law In The Anthropocene: Responding To The Geoengineering Challenge, Karen N. Scott

Michigan Journal of International Law

From The Odyssey to The Tempest and beyond, the control and deliberate manipulation of the weather constitutes an enduring and universal theme in myth and literature. In the twenty-first century, it is scientists and engineers rather than authors and artists who dream of weather and climate control, and their story, as described by James Rodger Fleming, "is not, in essence, a heroic saga about new scientific discoveries that can save the planet, as many of the participants claim, but a tragicomedy of overreaching, hubris, and self-delusion." This notwithstanding, the argument that we should deliberately manipulate earth systems and natural processes …

Measuring The Impact Of Melaleuca Quinquenervia Biochar Application On Soil Quality, Plant Growth, And Microbial Gas Flux, Thelma I. Velez

FIU Electronic Theses and Dissertations

Biochar has been heralded a mechanism for carbon sequestration and an ideal amendment for improving soil quality. Melaleuca quinquenervia is an aggressive and wide-spread invasive species in Florida. The purpose of this research was to convert M. quinquenervia biomass into biochar and measure how application at two rates (2% or 5% wt/wt) impacts soil quality, plant growth, and microbial gas flux in a greenhouse experiment using Phaseolus vulgaris L. and local soil.

Plant growth was measured using height, biomass weight, specific leaf area, and root-shoot ratio. Soil quality was evaluated according to nutrient content and water holding capacity. Microbial …

Thermal And Photochemical Interaction Of Co2 With Biochar, Eneruvie Uyoyou Okinedo

Electronic Theses and Dissertations

With interest in the changes that may occur to the carbonaceous portion of biochar obtain through the pyrolysis of biomass, the simple interaction between CO2 and biochar with water or a mixture of water and ethanol as hydrogen donor resulted in three significant observations. These reactions were carried out thermally at 333K and photochemically by simulating energy from the with a xenon lamp. The photochemical reaction involving biochar, CO2 with water or a mixture of water and ethanol as hydrogen donor led to a decrease in oxygen content of the parent biochar material, as observed by an increase in the …
