Agricultural Worker Injury Comparative Risk Assessment Methodology: Assessing Corn And Biofuel Switchgrass Production Systems, Gretchen A. Mosher, Saxon J. Ryan, Charles V. Schwab Dec 2017

Agricultural Worker Injury Comparative Risk Assessment Methodology: Assessing Corn And Biofuel Switchgrass Production Systems, Gretchen A. Mosher, Saxon J. Ryan, Charles V. Schwab

Charles V. Schwab

Keeping workers safe is a continuing challenge in agricultural production. Risk assessment methodologies have been used widely in other industries to better understand systems and enhance decision making, yet their use in production agriculture has been limited. This article describes the considerations and the approach taken to measure the difference in worker injury risks between two agricultural production systems. A model was developed specifically for the comparison of worker injury risk between corn and biofuel switchgrass production systems. The model is composed of injury and exposure values that were used in a Monte Carlo simulation. The output of this risk ...


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 Dec 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

Robert Horton

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 ...

Municipal Solid Waste And Circular Economies: A Case Study Of Madinah City, Mohammad Rehan, Iqbal Mohammad Ismail, Abdul-Sattar Nizami Oct 2017

Municipal Solid Waste And Circular Economies: A Case Study Of Madinah City, Mohammad Rehan, Iqbal Mohammad Ismail, Abdul-Sattar Nizami

Dr Mohammad Rehan

The world is facing many challenges including economic imbalances, food, water,
and energy shortages together with increasing environmental pollution and health risks. The
nations, especially developing countries, have to shift from the linear economy (taking, making,
consuming and throwing away) towards a circular economy (sharing, leasing, reusing, repairing,
refurbishing and recycling). In Kingdom of Saudi Arabia (KSA), the municipal solid waste (MSW)
is mostly disposed in open landfills or dump sites, without the recovery of value-added materials
and energy, potentially causing several environmental and public health issues. The KSA
government has recently launched a new policy of Vision 2030 to ...

Torrefaction Kinetics Of Hemp Hurds, An Emerging Agricultural Byproduct, In A Small Retort, Tel Jensen Sep 2017

Torrefaction Kinetics Of Hemp Hurds, An Emerging Agricultural Byproduct, In A Small Retort, Tel Jensen

Civil and Environmental Engineering Undergraduate Honors Theses

As knowledge concerning the consequences of unsustainable energy sources and agricultural practices grows, development of low-impact alternatives to both becomes more important. Sustainable sources of biomass offer solutions to both problems. This study characterized the reaction kinetics of torrefying an agricultural byproduct, the woody interior of hemp stems, or hurds. Torrefaction was carried out at 250 °C in small and simple retorts made of galvanized steel pipe. A first-order model most closely approximated the reaction. A sensitivity analysis was performed and the data was adjusted to correct for three potential sources of error, and regressed to find the best fit ...

Fondazione Eni Enrico Mattei Working Papers

The Paris Agreement has set stringent temperature targets to limit global warming to 2°C above preindustrial level, with efforts to stay well below 2°C. At the same time, its bottom-up approach with voluntary national contributions makes the implementation of these ambitious targets particularly challenging. Climate engineering – both through carbon dioxide removal (CDR) and solar radiation management (SRM) – is currently discussed to potentially complement mitigation and adaptation. Results from integrated assessment models already suggest a significant role for some forms of climate engineering in achieving stringent climate objectives1. However, these estimates and their underlying assumptions are uncertain and currently ...

Production Of Activated Carbon From Barley Biochar Precursor, Javier Pallarés, Ana González-Cencerrado, Inmaculada Ramos Aug 2017

Production Of Activated Carbon From Barley Biochar Precursor, Javier Pallarés, Ana González-Cencerrado, Inmaculada Ramos

Biochar: Production, Characterization and Applications

Agricultural production must be directed towards "sustainable agriculture", which preserves natural resources, reduces GHG emissions and maintains biodiversity. In this context, biochar is considered a product of great interest in agriculture since several studies have demonstrated its effectiveness in increasing agricultural yields, increasing the water retention capacity and nutrients in the soil, increasing the development of arbuscular mycorrhizal fungus (AMF), and ultimately improving the efficiency of fertilizers, thus reducing their use and reducing enviromental pollution.

Biochar Production Through Hydrothermal Carbonization: Energy Efficiency And Cost Analysis Of An Industrial-Scale Plant, Michela Lucian,, Fabio Merzari, Luca Fiori Aug 2017

Biochar Production Through Hydrothermal Carbonization: Energy Efficiency And Cost Analysis Of An Industrial-Scale Plant, Michela Lucian,, Fabio Merzari, Luca Fiori

Biochar: Production, Characterization and Applications

Hydrothermal carbonization (HTC) is an induced coalification process that converts raw biomass into a coal-like product, called hydrochar, characterized by high carbon content and high calorific value. This type of thermo-chemical conversion, also referred to as wet pyrolysis (or wet torrefaction), can be applied to a variety of non-traditional sources such as the organic fraction of municipal solid waste, wet agricultural residues, sewage sludge. Unlike traditional dry pyrolysis, the HTC process allows for the treatment of substrates with elevated moisture content, up to 75%–90%, without requiring a drying pre-treatment step.

Pyrolysis Of Residues From Well-Established Biochemical Processes For The Production Of Biochar, Devon Barry, Cedric Briens, Franco Berruti Aug 2017

Pyrolysis Of Residues From Well-Established Biochemical Processes For The Production Of Biochar, Devon Barry, Cedric Briens, Franco Berruti

Biochar: Production, Characterization and Applications

The main objective of this work is to use pyrolysis for the production of biochar from the residues of well-established biochemical processes. The residues that were selected come from two major conversion processes: biogas digesters, and wastewater treatment facilities. These processes produce unconverted lignin-rich residues, made of biomass components that are refractory to biochemical conversion. Pyrolysis is an aggressive thermochemical conversion process that is ideally suited to such residues. The desired biochar characteristics were determined by the specific needs of each industrial partner. The desired traits for the biochar obtained from sewage sludge were the capture, and stabilization of heavy ...


Investigation Of Innovative And Conventional Pyrolysis Of Ligneous And Herbaceous Biomasses For Biochar Production, Marina Morando, Silvia Fiore, Cedric Briens, Franco Berruti Aug 2017

Investigation Of Innovative And Conventional Pyrolysis Of Ligneous And Herbaceous Biomasses For Biochar Production, Marina Morando, Silvia Fiore, Cedric Briens, Franco Berruti

Biochar: Production, Characterization and Applications

Pyrolysis is a thermochemical process involving the thermolysis of carbon-based materials in absence of an oxidizing agent. Adjusting the operating conditions, in order to maximize the gaseous, liquid or solid products, may optimize pyrolysis process. This work investigates the performances of three laboratory-scale reactors on the grounds of the quantity and quality of the biochar obtained from different biomasses. Three types of biomass were fed to each reactor: two ligneous (rubberwood and eucalyptus) and one herbaceous (Phragmites australis). A novel reactor developed at ICFAR, the Jiggled Bed Reactor (JBR) was employed in slow pyrolysis mode.

Biochar Production Through Slow Pyrolysis Of Different Biomass Materials: Seeking The Best Operating Conditions, Joan J. Manyà, Manuel Azuara, José A. Manso Aug 2017

Biochar Production Through Slow Pyrolysis Of Different Biomass Materials: Seeking The Best Operating Conditions, Joan J. Manyà, Manuel Azuara, José A. Manso

Biochar: Production, Characterization and Applications

In the last years, special attention has been focused on analyzing the effect of pyrolysis conditions (mainly peak temperature) on the yield and properties of produced biochar. Given that the nature of biomass plays a key role in the pyrolysis process, it becomes really difficult to establish generic trends and correlations, which can be used for any biomass feedstock to predict the properties of derived biochar. Thus, more experimental studies focused on a given biomass source are still needed with the aim of providing reliable data for further research goals. In addition, a number of techniques have been proposed to ...

Production And Characterization Of Slow Pyrolysis Biochar From Lignin-Rich Digested Stillage From 2nd Generation Bioethanol Production, Frederik Ronsse, Dane Dickinson, Wolter Prins Aug 2017

Production And Characterization Of Slow Pyrolysis Biochar From Lignin-Rich Digested Stillage From 2nd Generation Bioethanol Production, Frederik Ronsse, Dane Dickinson, Wolter Prins

Biochar: Production, Characterization and Applications

Lignin-rich stillage from 2nd generation bioethanol production is a unique feedstock for slow pyrolysis and biochar production, as it contains high amounts of lignin (62 wt. % d.b) and ash (9.97 wt. % d.b) next to some residual cellulose and hemicellulose. As lignin is known to result in higher char and char-C yields compared to regular lignocellulosic feedstock, the suitability of a lignin-containing residue, obtained from a 2nd generation bio-ethanol pilot run using short rotation poplar, was subjected to anaerobic digestion for biogas production followed by slow pyrolysis of the digestate for the production of biochar.

Behavioral Factors Affecting The Adoption Of Biochar Of Farmers In Canada, Maren Oelbermann

Biochar: Production, Characterization and Applications

Biochar is a promising carbon-based soil amendment with ancient, South American roots. Despite its long history, research surrounding its use in modern agriculture has only just begun in North America. There are several studies examining biochar in soil, ranging from its effects on nutrient and water retention to the way it affects earthworms and other organisms. However, our understanding on the socioeconomic implications of using biochar as a soil amendment in temperate agriculture remains scarce. Our research aims to fill this gap through semi-structured interviews with farmers and the completion of an economic analysis based on market values of biochar ...


Life Cycle Assessment Of Biochar Production From Southern Pine, Sudhagar Mani, Yu Qiu Aug 2017

Life Cycle Assessment Of Biochar Production From Southern Pine, Sudhagar Mani, Yu Qiu

Biochar: Production, Characterization and Applications

Biochar, a major co-product from the pyrolysis of lignocellulosic biomass is rich in carbon and is often used as a soil amendment to promote crop production and as a soil carbon sequestration medium to maintain long-term soil health of marginal lands. Pyrolysis is the thermal decomposition of biomass in the absence of oxygen to primarily produce bio-oil with biochar being a co-product. Biochar is also primarily produced from wood logs using conventional carbonization methods (eg. Missouri kilns). For sustainable production of biochar, the most sustainable production route is important for large-scale production of biochar for soil carbon sequestration applications. The ...

Developing A Method Of Accounting For The Material Use Of Biomass/Biochar And Its Positive Side Benefits Within The Company Carbon Footprint: A Case Study At Hochschule Geisenheim University, Georg Ardissone, Claudia Kammann

Biochar: Production, Characterization and Applications

The federal state of Hesse announced the aim to achieve a „CO2-neutral administration“. In this context, the carbon footprint (CF) of the 16 universities in the federal area has been accounted. The CF by common units (kg CO2 per student or square meter) of the Hochschule Geisenheim University (HGU) is comparably high, due to the campus’ structure with (monument protected) building stock, a big share of greenhouses integrated into the campus and a comparably small number of students (Müller & Person, 2015, S. 27ff).

Evaluation Of The Long-Term Effects Of Pre-Conditioned Biochar On Soil Organic Carbon In Temperate Soils Using The Century Soil Organic Matter Model, Maren Oelbermann Aug 2017

Evaluation Of The Long-Term Effects Of Pre-Conditioned Biochar On Soil Organic Carbon In Temperate Soils Using The Century Soil Organic Matter Model, Maren Oelbermann

Biochar: Production, Characterization and Applications

Biochar contains a limited quantity of available mineral nutrients, requiring its addition in large quantities, in temperate soils, and in association with nitrogen (N) fertilizer and/or manure. Alternatively, biochar could be pre-conditioned with urea ammonium nitrate (UAN-enriched biochar), requiring lower inputs of biochar. The objective of this study was to evaluate the long-term (150 years) impact of the addition of UAN-enriched biochar on soil organic carbon (SOC), and soil active, slow and passive carbon (C) fractions compared to other commonly used agroecosystem management practices in a coarse and medium textured soil using the Century Soil Organic Matter Model.

Pyrolytic Temperature Evaluation Of Macauba Biochar For Uranium Adsorption From Aqueous Solutions, Sabine Neusatz Guilhen, Nilce Ortiz, Denise Alves Fungaro, Ondrej Masek Aug 2017

Pyrolytic Temperature Evaluation Of Macauba Biochar For Uranium Adsorption From Aqueous Solutions, Sabine Neusatz Guilhen, Nilce Ortiz, Denise Alves Fungaro, Ondrej Masek

Biochar: Production, Characterization and Applications

Macauba (Acrocomia aculeata) is a palm tree native to the tropical regions of America. In Brazil, it is prevalent in the savannah, known as “cerrado”. A valuable natural and renewable source of vegetable oil for food and cosmetic industries (nut oil) and for biodiesel (mesocarp oil), macauba has the potential to become the new “green gold” of Brazil, not only for its oil quality, but because it could solely be destined for commercial purposes, since it doesn’t compete with food market industry such as soybean and sugar cane. The dark stiff part that protects the nut, called “endocarp”, is ...
