Biochar Supplementation In Growing And Finishing Diets, Tommy M. Winders, Collin B. Freeman, Brittney A. Mark Mark, Melissa L. Jolly-Breithaupt, Hannah C. Hamilton, Jim C. Macdonald, Galen E. Erickson, Andrea K. Watson

Nebraska Beef Cattle Reports

Two metabolism studies were conducted to evaluate the effects of biochar (0, 0.8, or 3% of diet dry matter) on digestibility and methane production in growing and finishing diets. Intake was not affected by biochar inclusion in the growing diet and increased with 0.8% biochar inclusion in the finishing study. Digestibility tended to increase quadratically with biochar inclusion in the growing study while digestibility tended to linearly decrease with biochar inclusion in the finishing study. Methane production (g/d) decreased 10.7% in the growing study and 9.9% in the finishing study with 0.8% biochar compared ...


The Effect Of Cow Udder Score On Subsequent Calf Performance In The Nebraska Sandhills, Joslyn K. Beard, Jacki A. Musgrave, Rick N. Funston Funston, J. Travis Mulliniks Jan 2019

The Effect Of Cow Udder Score On Subsequent Calf Performance In The Nebraska Sandhills, Joslyn K. Beard, Jacki A. Musgrave, Rick N. Funston Funston, J. Travis Mulliniks

Nebraska Beef Cattle Reports

Cow records were evaluated over a 5-yr period to investigate how cow udder score affected calf growth and carcass performance. Cows from 2 calving herds, March and May, were classified as bad or good based on udder scores recorded at calving. Calves suckling dams with bad udders performed similarly during the pre-weaning period to good udder counterparts, with no differences in overall steer feedlot performance between udder groups. However, steers suckling good udder cows had heavier carcass weights and greater back fat thickness.


Waste To Carbon: Influence Of Structural Modification On Voc Emission Kinetics From Stored Carbonized Refuse-Derived Fuel, Andrzej Białowiec, Monika Micuda, Antoni Szumny, Jacek Łyczko, Jacek A. Koziel Jan 2019

Waste To Carbon: Influence Of Structural Modification On Voc Emission Kinetics From Stored Carbonized Refuse-Derived Fuel, Andrzej Białowiec, Monika Micuda, Antoni Szumny, Jacek Łyczko, Jacek A. Koziel

Agricultural and Biosystems Engineering Publications

The torrefaction of municipal solid waste is one of the solutions related to the Waste to Carbon concept, where high-quality fuel—carbonized refuse-derived fuel (CRDF)—is produced. An identified potential problem is the emission of volatile organic compounds (VOCs) during CRDF storage. Kinetic emission parameters have not yet been determined. It was also shown that CRDF can be pelletized for energy densification and reduced volume during storage and transportation. Thus, our working hypothesis was that structural modification (via pelletization) might mitigate VOC emissions and influence emission kinetics during CRDF storage. Two scenarios of CRDF structural modification on VOC emission kinetics ...


Torrefaction Of Sewage Sludge: Kinetics And Fuel Properties Of Biochars, Jakub Pulka, Piotr Manczarski, Jacek A. Koziel, Andrzej Białowiec Jan 2019

Torrefaction Of Sewage Sludge: Kinetics And Fuel Properties Of Biochars, Jakub Pulka, Piotr Manczarski, Jacek A. Koziel, Andrzej Białowiec

Agricultural and Biosystems Engineering Publications

We propose a ‘Waste to Carbon’ thermal transformation of sewage sludge (SS) via torrefaction to a valuable product (fuel) with a high content of carbon. One important, technological aspect to develop this concept is the determination of activation energy needed for torrefaction. Thus, this research aimed to evaluate the kinetics of SS torrefaction and determine the effects of process temperature on fuel properties of torrefied products (biochars). Torrefaction was performed using high ash content SS at six (200~300 °C) temperatures and 60 min residence (process) time. Mass loss during torrefaction ranged from 10~20%. The resulting activation energy for ...

Temporal Dynamics Of Bacterial Communities In Soil And Leachate Water After Swine Manure Application, Elizabeth L. Rieke, Michelle L. Soupir, Thomas B. Moorman, Fan Yang, Adina C. Howe

Agricultural and Biosystems Engineering Publications

Application of swine manure to agricultural land allows recycling of plant nutrients, but excess nitrate, phosphorus and fecal bacteria impact surface and drainage water quality. While agronomic and water quality impacts are well studied, little is known about the impact of swine manure slurry on soil microbial communities. We applied swine manure to intact soil columns collected from plots maintained under chisel plow or no-till with corn and soybean rotation. Targeted 16S-rRNA gene sequencing was used to characterize and to identify shifts in bacterial communities in soil over 108 days after swine manure application. In addition, six simulated rainfalls were ...

Quantification Of Voc Emissions From Carbonized Refuse-Derived Fuel Using Solid-Phase Microextraction And Gas Chromatography-Mass Spectrometry, Andrzej Białowiec, Monika Micuda, Antoni Szumny, Jacek Łyczko, Jacek A. Koziel

Agricultural and Biosystems Engineering Publications

In this work, for the first time, the volatile organic compound (VOC) emissions from carbonized refuse-derived fuel (CRDF) were quantified on a laboratory scale. The analyzed CRDF was generated from the torrefaction of municipal waste. Headspace solid-phase microextraction (SPME) and gas chromatography-mass spectrometry (GC-MS) was used to identify 84 VOCs, including many that are toxic, e.g., derivatives of benzene or toluene. The highest emissions were measured for nonanal, octanal, and heptanal. The top 10 most emitted VOCs contributed to almost 65% of the total emissions. The VOC mixture emitted from torrefied CRDF differed from that emitted by other types ...

Interactions Between Biochar And Compost In Organic Winter Wheat Production And Soil Quality Under Dryland Conditions, Phearen Kit Miller Dec 2018

Interactions Between Biochar And Compost In Organic Winter Wheat Production And Soil Quality Under Dryland Conditions, Phearen Kit Miller

All Graduate Theses and Dissertations

Organic wheat grown under dryland conditions encounters challenges such as limited nutrients and water. Maintaining organic wheat production requires solutions to these problems in order to retain economic sustainability for the farmers.

Research on biochar and compost have been conducted globally. Despite well known benefits of compost on soil and crop production, few organic farmers apply compost to their fields. Research on biochar is still new. Biochar is charcoal created from pyrolyzing agricultural material under conditions of low oxygen and high heat. Many studies claim that biochar is a valuable soil amendment for improving organic production and reducing environmental pollution ...


Soil Health Effects And Stakeholder Perceptions Of Manure And Woody Biomass Application To Cropland In Nebraska, Linda R. Schott Dec 2018

Soil Health Effects And Stakeholder Perceptions Of Manure And Woody Biomass Application To Cropland In Nebraska, Linda R. Schott

Biological Systems Engineering--Dissertations, Theses, and Student Research

Organic products that have historically been viewed as waste products may improve soil health by adding carbon (C) and nutrients to soil. Two such products are woodchips, generated from forest or rangeland management activities, and livestock manure. In Nebraska, eastern redcedar (Juniperus virginiana L.) is a native but invasive tree species inhibiting rangeland productivity. Livestock manure that is underutilized while inorganic fertilizers are imported for crop production presents a water quality risk by contributing to local- and regional-scale nutrient imbalances. Increasing the responsible use of livestock manure in crop fertility programs to improve sustainability of both livestock and crop farms ...


Evaluation Of Alternative Valorization Options For Institutional And Industrial Food Wastes, Swati Hegde Dec 2018

Evaluation Of Alternative Valorization Options For Institutional And Industrial Food Wastes, Swati Hegde

Theses

In recent years many countries and several regions in the United States have passed legislation on banning landfilling of organic waste. It is a well-known fact that organic wastes, including food scraps, generate methane under anaerobic landfill environments and contribute significantly to global warming. As more regions are mandated to follow the landfill ban, there is an increasing demand for alternative technologies for the disposal, treatment and upcycling of food wastes. Disposal and treatment may not result in any value-added products and hence are not the most efficient ways to manage food waste. As food waste has a high energy ...


Waste To Carbon: Densification Of Torrefied Refuse-Derived Fuel, Andrzej Białowiec, Monika Micuda, Jacek A. Koziel Nov 2018

Waste To Carbon: Densification Of Torrefied Refuse-Derived Fuel, Andrzej Białowiec, Monika Micuda, Jacek A. Koziel

Agricultural and Biosystems Engineering Publications

In this work, for the first time, the feasibility of obtaining carbonized refuse-derived fuel (CRDF) pelletization from municipal solid waste (MSW) was shown. Production of CRDF by torrefaction of MSW could be the future of recycling technology. The objective was to determine the applied pressure needed to produce CRDF pellets with compressive strength (CS) comparable to conventional biomass pellets. Also, the hypothesis that a binder (water glass (WG)) applied to CRDF as a coating can improve CS was tested. The pelletizing was based on the lab-scale production of CRDF pellets with pressure ranging from 8.5 MPa to 76.2 ...

Biosystems and Agricultural Engineering Faculty Publications

Valorization of lignin to high-value chemicals and products along with biofuel production is generally acknowledged as a technology platform that could significantly improve the economic viability of biorefinery operations. With a growing demand for electrical energy storage materials, lignin-derived activated carbon (AC) materials have received increasing attention in recent years. However, there is an apparent gap in our understanding of the impact of the lignin precursors (i.e., lignin structure, composition and inter-unit linkages) on the structural and electrochemical properties of the derived ACs. In the present study, lignin-derived ACs were prepared under identical conditions from two different lignin sources ...

Removal Of Antibiotic Resistance Genes In An Anaerobic Membrane Bioreactor Treating Primary Clarifier Effluent At 20 °C, Anthony D. Kappell, Lee K. Kimbell, Matthew Seib, Daniel Elliott Carey, Melinda J. Choi, Tino Kalayil, Masanori Fujimoto, Daniel Zitomer, Patrick J. Mcnamara

Civil and Environmental Engineering Faculty Research and Publications

Anaerobic membrane bioreactors (AnMBR) play a key role in future plans for sustainable wastewater treatment and resource recovery because they have no energy-intensive oxygen transfer requirements and can produce biomethane for renewable energy. Recent research results show that they can meet relatively stringent discharge limits with respect to BOD5 and TSS when treating municipal wastewater primary effluent. Sustainable used water recovery plans should also consider removal of unregulated pollutants. Antibiotic resistance genes (ARGs) represent an important emerging contaminant due to public health concerns surrounding the spread of infections resistant to common antibiotics. Conventional activated sludge processes have demonstrated mixed ...


Evaluation Of Three Forest-Based Bioenergy Development Strategies In The Inland Northwest, United States, Jill Moroney Nov 2018

Evaluation Of Three Forest-Based Bioenergy Development Strategies In The Inland Northwest, United States, Jill Moroney

Human-Environment Systems Research Center Faculty Publications and Presentations

In this article, we compare three bioenergy scenarios that use woody biomass from US Inland Northwest forests. The scenarios are based on current bioenergy research, development efforts, and stakeholder input. They include a small-scale system that produces drop-in transportation biofuel and biochar, a large, regional system that produces bio-aviation fuel, and a midsized pellet production system. We modeled woody biomass harvest, processing, and transportation, and then evaluated profitability and potential socioeconomic impacts to determine the overall viability of each strategy. Through interviews, we found widespread stakeholder support for all three scenarios. Wood-pellet production was profitable and feasible with current prices ...

Perennial Biomass Crop Establishment, Community Characteristics, And Productivity In The Upper Us Midwest: Effects Of Cropping Systems Seed Mixtures And Biochar Applications, Catherine L. Bonin, Rivka B. Fidel, Chumki Banik, David A. Laird, Robert Mitchell, Emily A. Heaton

Agronomy Publications

Native perennial plants have potential as bioenergy feedstocks, but their use is currently limited by relatively long establishment times and low biomass yields. Some research suggests that incorporating plant species diversity and applying biochar as a soil amendment might alleviate these limitations by creating a more resilient crop and soil system. The objective of this research was to investigate how 1) seeded plant diversity and 2) biochar soil amendments interact to affect the establishment, yield, and plant species composition of biomass cropping systems during the first four years of growth on productive soils. We measured species emergence, cover, peak and ...

Selective Glucose Isomerization To Fructose Via Nitrogen-Doped Solid Base Catalyst Derived From Spent Coffee Grounds, Season S. Chen, Iris K.M. Yu, Dong-Wan Cho, Hocheol Song, Daniel C.W. Tsang, Jean-Philippe Tessonnier, Yong Sik Ok, Chi Sun Poon

Chemical and Biological Engineering Publications

In this work, glucose isomerization to fructose was conducted via a solid base biochar catalyst derived from spent coffee grounds and melamine. The X-ray photoelectron spectroscopy (XPS) spectra identified the majority of pyridinic nitrogen on the biochar surface, which imparted the strong base character of the catalyst. Activity of the catalyst was evidenced by fast conversion of glucose (12%) and high selectivity to fructose (84%) in 20 min at a moderate temperature (120 °C) compared to recently reported immobilized tertiary amines at comparable N concentrations (10-15 mol% relative to glucose). By increasing the reaction temperature to 160 °C, fructose yield ...

Conservation Agriculture Practices Increase Potentially Mineralizable Nitrogen: A Meta-Analysis, Navreet K. Mahal, Michael J. Castellano, Fernando E. Miguez

Agronomy Publications

Potentially mineralizable nitrogen (PMN) is considered an important indicator of soil health. Cropping systems management can affect PMN. However, the effect size and relationship with crop yield across specific management practices remain uncertain. We conducted a quantitative review to understand how conservation agriculture management practices affect PMN including N fertilizer application, cropping system diversity, and tillage system as well as the relationship of crop yield with PMN. Data were extracted from 43 studies published in peer-reviewed journals, providing 494 paired comparisons of PMN and 26 paired comparisons of PMN and yield across selected crop management practices. In our meta-analysis, the ...


Removal Efficiencies, Uptake Mechanisms And Competitive Effects Of Copper And Zinc In Various Stormwater Filter Media, Emily Heleva-Ponaski Sep 2018

Removal Efficiencies, Uptake Mechanisms And Competitive Effects Of Copper And Zinc In Various Stormwater Filter Media, Emily Heleva-Ponaski

Dissertations and Theses

Polluted stormwater, if not treated, can compromise water quality throughout our hydrologic cycle, adversely affecting aquatic ecosystems. Common stormwater pollutants, copper and zinc, have been identified as primary toxicants in multiple freshwater and marine environments. For small-scale generators, stormwater management can be cumbersome and implementation of common BMPs impractical thus catch basins are popular though not the most environmentally conscious and sustainable option. This study aims to characterize the potential of a mobile media filter operation for the treatment and on-site recycling of catch basin stormwater. The removal capacities of various commercially available filter media (e.g. a common perlite ...

Anaerobic Digestion Of Aqueous Pyrolysis Condensate, Connie Wen Aug 2018

Anaerobic Digestion Of Aqueous Pyrolysis Condensate, Connie Wen

Electronic Thesis and Dissertation Repository

Lignocellulosic material can be subjected to pyrolysis to yield pyrolysis liquid, biochar, and gas. The pyrolysis liquid resulting from the condensation of vapours can be separated into a rich organic condensate and an acidic “aqueous pyrolysis condensate” (APC) which may be considered a waste. The target of this research is subjecting APC to anaerobic digestion to produce biogas that can be energy purposed, and to reduce the organic load of APC to acceptable levels for possible disposal. From this study, it was found that without any treatment, the inoculum requires 50 to 60 days of adaptation period to reduce the ...

Water Treatment Residual Coated Wood Mulch For Mitigation Of Toxic Metals And Phosphate From Polluted Urban Stormwater Runoff, Hanieh Soleimanifar

Theses, Dissertations and Culminating Projects

Polluted urban runoff as a primary non-point pollution source poses a serious threat to urban human and ecological health. Various urban runoff pollutants challenge the exiting stormwater treatment systems. To support the development of a sound and sustainable urban stormwater management, this dissertation targets at transforming a common landscaping practice, i.e. mulching, into a new stormwater treatment technology through coating aluminum water treatment residual (Al-WTR) on the surface of wood mulch chips. WTR is an industrial waste produced from drinking water treatment plants and primarily comprises amorphous aluminum (hydr)oxides. The Al-WTR coating on the modified wood mulch enables ...


Metal Reactivity In Laboratory Burned Wood From A Watershed Affected By Wildfires, Asifur Rahman Jul 2018

Metal Reactivity In Laboratory Burned Wood From A Watershed Affected By Wildfires, Asifur Rahman

Civil Engineering ETDs

Massive amounts of wood ash are deposited into nearby streams as a result of runoff from storm events after increasing frequency of wildfire events that negatively affect water quality. Ash and debris from burned vegetation can alter the pH, turbidity and dissolved oxygen (DO) in water and can release heavy metals, organic matter, and nutrients. We investigated interfacial processes affecting metal mobility in wood ash burned under laboratory-controlled conditions using aqueous chemistry, microscopy and spectroscopy analyses. Wood was collected from the Valles Caldera National Preserve in New Mexico which has experienced two wildfires since 2011 that have caused devastating effects ...

The Role Of Mycelium In Bioretention Systems: Evaluation Of Nutrient Retention In Mycorrhizae-Inoculated Mescocosms, Cara J. Poor, Casey Balmes, Michael Freudenthaler, Ashley Martinez Jun 2018

The Role Of Mycelium In Bioretention Systems: Evaluation Of Nutrient Retention In Mycorrhizae-Inoculated Mescocosms, Cara J. Poor, Casey Balmes, Michael Freudenthaler, Ashley Martinez

Engineering Faculty Publications and Presentations

Bioretention systems have become an increasingly common method for treating stormwater in urban areas, which help reduce peak flows and remove contaminants from stormwater. However, nutrients often leach out of the bioretention soil mix, which can contribute to the degradation of receiving waters in bioretention systems with underdrains. Development of mycelium may improve retention of nutrients and increase the water-holding capacity. To evaluate the impact of mycelium on nutrient leaching from bioretention systems, ectomycorrhizal and endomycorrhizal fungi were added to the bioretention soil mix to promote mycelium growth. A proprietary mix with bacteria and mycorrhizal fungi also was tested. Mesocosms ...
