Daniel S. Andersen

Managing the environmental impacts associated with livestock production is a challenge for farmers, public and regulatory agencies. Sustainable solutions that take into account technical and socioeconomic factors are needed. For example, the comprehensive control of odors, ammonia (NH3), hydrogen sulfide (H2S), and greenhouse gas (GHG) emissions from swine production is a critical need. Stored manure is a major source of gaseous emissions. Mitigation technologies based on bio-based products such as biochar are of interest due to the potential benefits of nutrient cycling. The objective of this study was to test non-activated (non-functionalized) biochar for the mitigation of gaseous emissions from ...

Pilot-Scale Concept Of Real-Time Wind Speed-Matching Wind Tunnel For Measurements Of Gaseous Emissions, Devin Maurer, Jacek A. Koziel, Kelsey M. Bruning, David B. Parker Aug 2017

Pilot-Scale Concept Of Real-Time Wind Speed-Matching Wind Tunnel For Measurements Of Gaseous Emissions, Devin Maurer, Jacek A. Koziel, Kelsey M. Bruning, David B. Parker

Devin L. Maurer

Comprehensive control of odors, hydrogen sulfide (H2S), ammonia (NH3) and odorous volatile organic compound (VOC) emissions associated with animal production is a critical need. Current methods utilizing wind tunnels and flux chambers for measurements of gaseous emissions from area sources such as feedlots, lagoons, pastures and cropland are often criticized for potential bias. The bias is due to the temporal isolation of the emitting surface, affecting the air velocity and temperature at the surface, forcing controlled surface-to-gas-phase mass transfer, and therefore, affecting emission measurements. That bias can limit the applicability of these methods to relative and comparative ...


Farm-Scale Testing Of Soybean Peroxidase And Calcium Peroxide For Surficial Swine Manure Treatment And Mitigation Of Odorous Vocs, Ammonia And Hydrogen Sulfide Emissions, Devin L. Maurer, Jacek A. Koziel, Kelsey Bruning, David B. Parker Aug 2017

Farm-Scale Testing Of Soybean Peroxidase And Calcium Peroxide For Surficial Swine Manure Treatment And Mitigation Of Odorous Vocs, Ammonia And Hydrogen Sulfide Emissions, Devin L. Maurer, Jacek A. Koziel, Kelsey Bruning, David B. Parker

Devin L. Maurer

The swine industry, regulatory agencies, and the public are interested in farm-tested methods for controlling gaseous emissions from swine barns. In earlier lab- and pilot-scale studies, a renewable catalyst consisting of soybean peroxidase (SBP) mixed with calcium peroxide (CaO2) was found to be effective in mitigating gaseous emissions from swine manure. Thus, a farm-scale experiment was conducted at the university's 178-pig, shallow-pit, mechanically-ventilated swine barn to evaluate SBP/CaO2 as a surficial manure pit additive under field conditions. The SBP was applied once at the beginning of the 42-day experiment at an application rate of 2.28 ...


The Nitrogen Legacy: Emerging Evidence Of Nitrogen Accumulation In Anthropogenic Landscapes, K J Van Meter, N B Basu, J J Veenstra, C. Lee Burras Jul 2017

The Nitrogen Legacy: Emerging Evidence Of Nitrogen Accumulation In Anthropogenic Landscapes, K J Van Meter, N B Basu, J J Veenstra, C. Lee Burras

C. Lee Burras

Watershed and global-scale nitrogen (N) budgets indicate that the majority of the N surplus in anthropogenic landscapes does not reach the coastal oceans. While there is general consensus that this 'missing' N either exits the landscape via denitrification or is retained within watersheds as nitrate or organic N, the relative magnitudes of these pools and fluxes are subject to considerable uncertainty. Our study, for the first time, provides direct, large-scale evidence of N accumulation in the root zones of agricultural soils that may account for much of the 'missing N' identified in mass balance studies. We analyzed long-term soil data ...

Trace Metals In Stormwater: Alternative Best Management Practices, Jennifer Ibeth Mora Jun 2017

Trace Metals In Stormwater: Alternative Best Management Practices, Jennifer Ibeth Mora

Civil and Environmental Engineering Master's Project Reports

Heavy metals, such as copper (Cu) and zinc (Zn), are considered hazardous in natural waters due to their toxicity and non-biodegradability. The focus of this study is to use batch experiments to investigate the heavy metal (Cu and Zn) removal efficiency of perlite and EarthliteTM to improve in-situ filtration systems for stormwater catchment basins. Stormwater samples from two field sites in Portland, OR, chosen to represent a high-use commercial site and high-traffic urban road, were characterized to inform experimental design and compare to values found in literature. The Linear, Freundlich, and Langmuir isotherm models were used to describe equilibrium ...


Partnerships In Sustainability: The Transition Town Movement In Minnesota, Leslie Mackenzie, Marty Lewis-Hunstiger Jun 2017

Partnerships In Sustainability: The Transition Town Movement In Minnesota, Leslie Mackenzie, Marty Lewis-Hunstiger

Interdisciplinary Journal of Partnership Studies

Transition Towns is a citizen-led movement that seeks to address individual and societal dependence on fossil fuels and the need to reduce greenhouse gas production in order to fight climate change. The foundation of Transition is permaculture, a design process based on whole-systems thinking informed by the patterns and relationships found in nature. Since its inception in 2005, the Transition movement has spread worldwide, as people in small groups and across large towns look for ways to take practical action to fight climate change: from home vegetable gardens to weatherization work parties, from time banks and tool shares to renewable ...


Producing Energy While Sequestering Carbon? The Relationship Between Biochar And Agricultural Productivity, Nathan Kauffman, Jerome Dumortier, Dermot J. Hayes, Robert C. Brown, David Laird Jun 2017

Producing Energy While Sequestering Carbon? The Relationship Between Biochar And Agricultural Productivity, Nathan Kauffman, Jerome Dumortier, Dermot J. Hayes, Robert C. Brown, David Laird

Robert C. Brown

A partial solution to problems associated with anthropogenic greenhouse gas (GHG) emissions could be the development and deployment of carbon-negative technologies, i.e., producing energy while reducing atmospheric carbon dioxide levels. Biofuels have been considered a possibility but have faced limitations due to competition with food production and GHG emissions through indirect land-use change (ILUC). In this article, we show how emissions from ILUC can potentially be reduced by producing food and bioenergy from biochar amended soils. The possibility of yield improvements from biochar would reduce the land requirement for crop production and thus, lead to a reduction in emissions ...

Biochar And Managed Perennial Ecosystems: Testing For Synergy In Ecosystem Function And Biodiversity, Lori A. Biederman, W. Stanley Harpole

Lori A. Biederman

Biochar is a carbon-rich material that is similar to charcoal. It is produced when biomass is burned in the absence of oxygen, a process otherwise known as pyrolysis. Pyrolysis and the production of biochar are currently being promoted as a means to both produce domestic fuel (biooil) and concurrently producing a co-product that increases crop yield and sequesters carbon in the soil (biochar). While there may be many potential benefits in the application of biochar to agricultural soils, such as enhanced soil fertility and improved soil water status, there are no studies of higher-order ecological and ecosystem effects of biochar ...


Hybrid Thermochemical Processing: Fermentation Of Pyrolysis-Derived Bio-Oil, Laura R. Jarboe, Zhiyou Wen, Dong Won Choi, Robert C. Brown Jun 2017

Hybrid Thermochemical Processing: Fermentation Of Pyrolysis-Derived Bio-Oil, Laura R. Jarboe, Zhiyou Wen, Dong Won Choi, Robert C. Brown

Laura R. Jarboe

Thermochemical processing of biomass by fast pyrolysis provides a nonenzymatic route for depolymerization of biomass into sugars that can be used for the biological production of fuels and chemicals. Fermentative utilization of this bio-oil faces two formidable challenges. First is the fact that most bio-oil-associated sugars are present in the anhydrous form. Metabolic engineering has enabled utilization of the main anhydrosugar, levoglucosan, in workhorse biocatalysts. The second challenge is the fact that bio-oil is rich in microbial inhibitors. Collection of bio-oil in distinct fractions, detoxification of bio-oil prior to fermentation, and increased robustness of the biocatalyst have all proven effective ...


Macroporous Carbon Supported Zerovalent Iron For Remediation Of Trichloroethylene, Michael Lawrinenko, Zhuangji Wang, Robert Horton, Deyny Mendivelso-Perez, Emily A. Smith, Terry E. Webster, David A. Laird, Johannes Van Leeuwen Jun 2017

Macroporous Carbon Supported Zerovalent Iron For Remediation Of Trichloroethylene, Michael Lawrinenko, Zhuangji Wang, Robert Horton, Deyny Mendivelso-Perez, Emily A. Smith, Terry E. Webster, David A. Laird, Johannes Van Leeuwen

Emily Smith

Groundwater contamination with chlorinated hydrocarbons has become a widespread problem that threatens water quality and human health. Permeable reactive barriers (PRBs), which employ zerovalent iron, are effective for remediation; however, a need exists to reduce the economic and environmental costs associated with constructing PRBs. We present a method to produce zerovalent iron supported on macroporous carbon using only lignin and magnetite. Biochar-ZVI (BC-ZVI) produced by this method exhibits a broad pore size distribution with micrometer sized ZVI phases dispersed throughout a carbon matrix. X-ray diffraction revealed that pyrolysis at 900 °C of a 50/50 lignin–magnetite mixture resulted in ...

Fluid Fertilizer’S Role In Sustaining Soils Used For Bio-Fuels Production, John L. Kovar, Douglas Karlen

Douglas L Karlen

The short- and long-term effects on soil nutrient cycling, physical properties, and biological activity of striving for higher grain yields and removing crop residues for bio-fuels production must be understood to provide more quantitative crop and soil management guidelines. This study focuses on potassium (K) and sulfur (S) requirements of corn (Zea mays L.) grown for bioenergy feedstock production. Our objectives for 2008 were to: i) evaluate the performance of several S fertilizers, including liquid ammonium thiosulfate (12-0-0-26S), as S sources for corn grown in Iowa, and ii) establish a comprehensive tillage, nutrient management, crop residue removal, and cover crop ...


Crop Residues: The Rest Of The Story, Douglas L. Karlen, Rattan Lal, Ronald F. Follett, John M. Kimble, Jerry L. Hatfield, John A. Miranowski, Cynthia A. Cambardella, Andrew Manale, Robert P. Anex, Charles W. Rice Jun 2017

Crop Residues: The Rest Of The Story, Douglas L. Karlen, Rattan Lal, Ronald F. Follett, John M. Kimble, Jerry L. Hatfield, John A. Miranowski, Cynthia A. Cambardella, Andrew Manale, Robert P. Anex, Charles W. Rice

Douglas L Karlen

Synopsis In the February 15, 2009 issue of ES&T Strand and Benford argued that oceanic deposition of agricultural crop residues was a viable option for net carbon sequestration (43 [4], 1000−1007). In reviewing the calculations and bringing their experience to bear, Karlen et al. argue in this Viewpoint that crop residue oceanic permanent sequestration (CROPS) as envisioned by Strand and Benford will not work. They further propose alternative possibilities in agricultural methods to achieve a net decrease of CO2 emissions.

Biochar And Nitrogen Effects On Winter Wheat Growth, T. E. Zee, N. O. Nelson, G. Newdigger

Kansas Agricultural Experiment Station Research Reports

Biochar, a co-product of thermochemical bioenergy production, may be a valuable soil amendment, but little is known about its potential long-term effects on plant growth and soil fertility. In order to gain more information, this experiment was performed to see if the addition of biochar, in comparison to lime and fertilizer treatments, has the potential to return key nutrients back to the soil or increase crop yield. A field study to investigate the effects of biochar on plant growth was initiated in 2011 near St. John, KS. Treatments included biochar applied at 16.6 ton/a (biochar), lime and annual ...


Reviewing Biochar Research And Introducing A Possible Classification System, Patricia G. Burns May 2017

Reviewing Biochar Research And Introducing A Possible Classification System, Patricia G. Burns

Research Papers

Biochar is the product of burning biomass, such as hardwood, rice hulls, bamboo, or even chicken litter, in a low- to no-oxygen environment. The result is a black carbon skeletal-like structure of the original biomass.

Research into biochar as a soil amendment has been influenced by the study of anthropogenic dark, richly fertile soils found in the Amazon rainforest where the native forest soil is acidic and low in fertility. Biochar research for amending agricultural soils is relatively new but there are strong indications that this practice can decrease the need for additional fertilizer and water inputs.

Biochar products will ...


Pine Needle Pyrolysis: Bio-Waste Into Biofuel, Alexandra Fuentes May 2017

Pine Needle Pyrolysis: Bio-Waste Into Biofuel, Alexandra Fuentes

Honors Theses and Capstone Projects

This project explores the alternate uses of biomass. In particular it focuses on pine needles as a source for biofuels. Pine needles are of interest because in certain Mountain communities they are collected and removed from residential properties. By removing the pine needles, communities create a “defensible space” to prevent wild fires from destroying homes and property. These needles are often placed in regional landfills. The South Tahoe Refuse and Recycling Services alone has more than 4,340 tons of pine needles dumped at their facility annually. This large amount of biomass can be a potential energy source.

The focus ...


Life Cycle Assessment Of Sweet Sorghum As Feedstock For Second-Generation Biofuel Production, Karla Morrissey May 2017

Life Cycle Assessment Of Sweet Sorghum As Feedstock For Second-Generation Biofuel Production, Karla Morrissey

Chemical Engineering Undergraduate Honors Theses

There exist few life cycle assessments (LCAs) in the literature that focus on the second-generation biofuel production from sweet sorghum, a non-food-source feedstock that offers several advantages in terms of farming requirements compared to corn or sugarcane. The objective of this LCA study was to evaluate biofuels produced from sweet sorghum to determine the potential environmental benefits of producing sweet sorghum biofuel compared to conventional fossil fuels. The biofuel production process used for this study differed from other LCAs in that, in parallel to stalk juice extraction and fermentation, residual bagasse and vinasse was pyrolyzed and upgraded to a diesel ...


Evaluation Of Phosphorous Removals By Biochar Supported Nano-Scale Zero-Valent Iron, Maria S. Rossetti May 2017

Evaluation Of Phosphorous Removals By Biochar Supported Nano-Scale Zero-Valent Iron, Maria S. Rossetti

Chemical Engineering Undergraduate Honors Theses

This study evaluated the effectiveness of biochar-supported nano-scale zero-valent iron (nZVI/BC) in removing phosphorus (P) from water. Samples of nZVI/BC were prepared using aqueous nanoparticles synthesis techniques, and were mixed with a stock phosphorus solution. To determine P reductions water samples were tested for P content using the ascorbic acid method. This procedure was repeated for samples of stock P solution, zero-valent iron (ZVI), biochar, and ZVI/BC. nZVI/BC reduced P content by 86% whereas ZVI, biochar, and ZVI/BC removed 6%, -23%, and 17% respectively. This suggests that nZVI/BC has the potential to be an ...


Trihalomethane, Dihaloacetonitrile, And Total N-Nitrosamine Precursor Adsorption By Carbon Nanotubes: The Importance Of Surface Oxides And Pore Volume, Erin Needham May 2017

Trihalomethane, Dihaloacetonitrile, And Total N-Nitrosamine Precursor Adsorption By Carbon Nanotubes: The Importance Of Surface Oxides And Pore Volume, Erin Needham

Theses and Dissertations

As drinking water sources become increasingly impaired, enhanced removal of natural organic matter (NOM) may be required to curb formation of disinfection byproducts (DBPs) upon chlor(am)ination. While carbon nanotubes (CNTs) can adsorb NOM, their properties for DBP precursor adsorption have not been elucidated. Nine types of CNTs were assessed for trihalomethane (THM), dihaloacetonitrile (DHAN), and total N-nitrosamine (TONO) precursor adsorption. Batch isotherm experiments were completed with lake water and, to simulate an impaired condition, effluent from a wastewater treatment plant (WWTP). Adsorption varied with CNT type and dose, with TONO precursors having the highest percent removals from WWTP ...

Spatial Distribution Of Sequestered Metals In An Arid Southern California Bioswale, Zachary Evans

2017 Claremont Colleges Library Undergraduate Research Award

Bioswales are a type of permeable green infrastructure designed to slow storm water runoff, and clean runoff by sequestering pollutants such as heavy metals. The influence of bioswale features such as slope, terrain, soil type, depth, and vegetation on the efficacy of bioswales in processing storm water runoff is an active area of research aimed partly at optimizing bioswale design and construction. Concentrations of aluminum, cobalt, chromium, copper, iron, magnesium, manganese, nickel, lead, vanadium and zinc were measured in surface soil, depth soil, and at several plant locations. The distribution of metals in surface, depth, and rhizosphere soil fractions were ...


Biochar Derived From Cotton Fiber Feedstock: Characterization Of Material And Potential For Adsorptive Capacity, Lucas Marshall, William Wei, Megan Fuller Apr 2017

Biochar Derived From Cotton Fiber Feedstock: Characterization Of Material And Potential For Adsorptive Capacity, Lucas Marshall, William Wei, Megan Fuller

CSHLA Scholar Day

Introduction

Anthropogenic contaminants in surface waters have increased in complexity as the use of chemicals in all sectors of society has grown [1]. Water scarcity and quality issues will require robust, low-cost, and sustainable solutions.

Biochars are particularly compelling as adsorptive solids because they repurpose wastes [2, 3] from other industries and are often carbon neutral, if not carbon negative. Cotton is the most common cellulosic fiber on the global fiber market, and as such, a significant contributor to municipal waste streams [4]. This research investigates the use of undyed, unbleached, 100% cotton muslin fabric as the fuel for making ...


Does Biochar Improve Disturbed, Sandy Soils?, Kathleen Fast Apr 2017

Does Biochar Improve Disturbed, Sandy Soils?, Kathleen Fast

16th Annual Celebration of Undergraduate Research and Creative Performance (2017)

We studied whether adding biochar to sandy, carbon-poor soil impacts plant growth. Biochar is an organic compound composed mainly of black carbon. Biochar is of interest as a possible soil amendment to alleviate stresses on agricultural production due to its high water and nutrient retention capabilities, high cation exchange capacity, high porosity that increases mycorrhizal growth, and ability to sequester carbon dioxide. Our experiment involved using three different plant types, Avena sativa (common oat), Vigna radiata (mung bean), and Raphanus sativus (cherry belle radish), in greenhouse and garden plot experiments. In the greenhouse we used five different treatments of soil ...
