In the context of global energy supply, cellulosic ethanol plays an essential role due to being considered a renewable fuel and minimize environmental emissions when compared to the exploration and utilization of fossil fuels. However, the cellulosic ethanol production requires pretreatment before the fermentation process, which is considered an expensive procedure that makes the cellulosic ethanol production costly. Therefore, the main goal of this research was to evaluate the economic and environmental impacts of using low-moisture anhydrous ammonia (LMAA) pretreatment for five different scenarios, which were 1000 tonne (t) of feedstock per day (Scenario I), 2000 t/d (Scenario II), 3000 t/d (Scenario III), 5000 t/d (Scenario IV), and 10,000 t/d (Scenario V), for ethanol production from sugarcane bagasse by using SuperPro software. Life Cycle Assessment (LCA) and Techno-Economic Analysis (TEA) were used to evaluate the feasibility and environmental impacts of the scenarios simulated. From the results, the capital costs increased according to the increase of the feedstock amount to be processed, having the most significant investment to the largest facility simulated (10,000 t/d). Mostly all the scenarios presented material costs (sugarcane bagasse, enzyme, yeast, and ammonia costs) as the expenses that impacted the most the overall annual operating costs, where sugarcane bagasse and ammonia were the responsible for around 58% and 40% of the total investment for material costs. In addition, from utility costs, it was observed that electricity represented around 45% of the annual utility costs for almost all the scenarios simulated. All the scenarios resulted in negative profit, and sensitivity analysis showed that ethanol sale price was the parameter that presented the greatest sensitivity for sugarcane bagasse ethanol production under LMAA pretreatment conditions evaluated in this study. Related to environmental aspects, the LCA results showed that the 2000 t/d facility simulated (Scenario II) presented the lowest Global Warming Potential (GWP) for several electricity supply technologies analyzed and presented a significant reduction of CO2 equivalent emissions, representing more than 80% lower greenhouse gasses emissions (GHG) when compared to the 10,000 t/d facility simulated (Scenario V).

With the development of agricultural biorefineries and bioprocessing operations, understanding the economic efficiencies and environmental impacts for these have gradually become popular for the deployment of these industrial processes. The corn-based ethanol and soybean oil refining industries have been examined extensively over the years, especially details of processing technologies, including materials, reaction controls, equipment, and industrial applications. The study focused on examining the production efficiency changes and economic impacts of integrating products from the enzyme-assisted aqueous extraction processing (EAEP) of soybeans into corn-based ethanol fermentation processing. Using SuperPro Designer to simulate production of corn-based ethanol at either 40 million gallons per year (MGY) or 120 MGY, with either oil separation or no oil removal, we found that indeed integrating soy products into corn ethanol fermentation may be slightly more expensive in terms of production costs, but economic returns justify this integration due to substantially greater quantities of ethanol, distillers corn oil, and distillers dried grains with solubles being produced.

Aspartic acid, or “aspartate,” is a non-essential, four carbon amino acid produced and used by the body in two enantiomeric forms: L-aspartic acid and D-aspartic acid. The L-configuration of amino acids is the dominant form used in protein synthesis; thus, L-aspartic acid is by far the more common configuration. However, D-aspartic acid is one of only two known D-amino acids biosynthesized by eukaryotes. While L-aspartic acid is used in protein biosynthesis and neurotransmission, D-aspartic acid is associated with neurogenesis and the endocrine system. Aspartic acid production and use has been growing in recent years. The purpose of this article is to discuss various perspectives on aspartic acid, including its industrial utility, global markets, production and manufacturing, optimization, challenges, and future outlook. As such, this review will provide a thorough background on this key biochemical.

Background and objectives Following mechanical harvest, shelled corn is susceptible to decreased quality in storage environments. The rate at which shelled corn deteriorates is dependent upon numerous factors, but temperature and moisture content are predominant. The standard methodology for quantifying grain deterioration is to express it as a percent dry matter loss, where 0.5% dry matter loss corresponds directly with a number of safe storage days, known as allowable storage time (AST). However, current shelled corn allowable storage time values, based on ASABE standard D535, are only applicable for a specific temperature and a specific moisture content. Therefore, this study simulated and reviewed how natural temperature variation dynamically affects the response in shelled corn allowable storage time. Findings Two separate simulations were configured, and the results showed that, depending on the given moisture content, temperature trends, and when shelled corn is initially placed in storage, AST can be extended at certain points throughout the year. Additionally, it was revealed that there is a considerable difference between dynamic AST values and static (traditional) AST values contained within the current shelled corn storage time chart. Conclusions The number of safe allowable storage days is substantially impacted by grain moisture and deviations in daily temperature. Significance and novelty The study makes an important contribution toward understanding the dynamic storage behavior of corn due to changes in temperature and moisture levels. This research builds on current knowledge, but it presents a more refined estimation of theoretical shelled corn allowable storage time.

The Biomass Bandwagon: Three Ideas for Engineering and Technology Programs to Get Onboard Abstract As society demands more energy and material goods, engineers and technologists will be relied upon to design and implement systems to produce and deliver these. There is growing interest in using renewable resources to produce fuels, chemicals, and finished products to meet these increasing needs. Additionally, popularity is gaining, both in research as well as industry, in developing and commercializing biobased products. Within this arena, there are tremendous opportunities for teaching innovations as well. To date, very limited discussions at ASEE regarding these potentials have occurred. The goal of this paper is to discuss possibilities for augmenting engineering and technology curricula by incorporating various concepts from biomass processing and utilization. We will discuss three specific topics that are germane to the fields of engineering and technology, and could easily be infused into existing coursework. These include quality control, engineering economics, and biocomposite manufacturing. Because the role of the instructor is to utilize advances in research to bolster the classroom, and because the interest and actual utilization of biomass is currently burgeoning, incorporating these topics could provide a tremendous boost in student interest in coursework, as well as bolster the workforce who will be working in the emerging bioeconomy. Introduction To meet the needs of dynamic markets and global technological changes, it is important for engineering and technology programs to adapt as they move toward the future. A thorough review of some of these needs has been provided.1 One area that is becoming increasingly important is alternative energy, which has many facets to consider.2 Interest in this area has been growing, and has become fertile ground for innovative individual projects,3 courses,4 and even entire degree programs.5 Including these topics in existing coursework has also been explored.6 Although wind, solar, hydroelectric, and geothermal sources have been the staple of most of the discussions regarding renewable energy over the years, biofuels and biomass have recently become mainstream topics as well. The opportunities that biorenewable energy and bio-based products offer to engineering and technology programs has been discussed thoroughly.7, 8 Concurrently, the role of biology in many traditional engineering disciplines has been increasing in popularity as well.9, 10 Although the literature is still fairly sparse, it is growing, especially in terms of laboratory experiences for undergraduates. For example, biology has been infused into materials engineering coursework,11 and has also been used in chemical engineering laboratory courses.12, 13 Using biomass as an energy source has been incorporated into laboratory modules to examine thermodynamics.14 Biology concepts have also been integrated into laboratory exercises focusing on biodegradable polymers.15, 16 Another study has reported the development of a module that examines the production of beer in a laboratory setting.17

Not Just Informative, but Necessary: Infusing Green and Sustainable Topics into Engineering and Technology Curricula Abstract Generally accepted duties of engineers and technologists encompass designing and implementing solutions to problems. When so doing, it is their responsibility to be cognizant of the impacts of their designs on, and thus their accountability to, not only society in general, but also subsequent effects upon the environment. They need to be able to concurrently satisfy these competing needs, as well as constraints specific to the design challenges at hand. Responding to these requirements are the growing fields of green engineering and sustainable engineering. Both of these areas encompass many concepts, ideas, and tools, all of which are essential information for graduates to know and understand. Many degree programs do not offer this type of information to their students. It is true that modifying curricula can be challenging, especially as pressure mounts to teach the students more information, but not extend their tenure at the university. Toward that end, the goal of this paper is to discuss three key topics that can be readily infused into existing coursework with minimal disruption: raw materials, process efficiencies, and wastes/byproducts. These three themes are essential to any engineering field or application, whether discussing design, manufacturing operations, management, service operations, or energy production, to name only a few. These concepts apply to traditional engineering materials and even to organic and biological processing, and they extend fully across the engineering spectrum, from product conception to end-of-life. Indeed, these three topics are multidisciplinary in nature. In this paper we will discuss each of these topics in turn, and how to infuse each of them into engineering and technology coursework (there are a variety of ways to successfully incorporate them into existing curricula). We will also provide a resource base that educators can use when pursuing such an endeavor. Augmenting undergraduate and graduate instruction is a strategy that can reap profound rewards, not only because trained graduates will enter the workforce equipped with this knowledge, but bolstering curricula can raise awareness of these topics on many levels, ranging from the students themselves to the public at large. Introduction In recent years there has been growing interest in environmental concerns across a broad spectrum of our society. This has been reflected in publications such as1, 2, 3. Most recently, “An Inconvenient Truth” has captured the attention of the public, and has brought the environment, and the effects of human activities, to the forefront of many people’s minds4. Now, the media is routinely filled with articles discussing these topics. Some of these have begun to focus on technologies, manufacturing practices, and the products which are produced. A few examples include industrial chemicals5, green solvents6, green consumer products7, and environmentally- benign separations processes8.

BIOREFINING OF RENEWABLE RESOURCES – EMERGING OPPORTUNITIES FOR ENGINEERING EDUCATION Abstract The society in which we live has developed an insatiable demand for energy and material goods. Historically these needs have primarily been met by utilizing fossil fuels and other non- renewable raw materials. As environmental concerns grow, however, renewable resources are gaining increased attention. This paper examines industrial biorefineries, which are at the leading edge of the development of emerging biobased industries. Biorefineries, similar in concept to traditional petroleum refineries, utilize various conversion technologies to produce multiple products, including fuels, chemicals, industrial products, and electrical power from renewable biomass sources, such as corn stover, residue straw, perennial grasses, legumes, and other materials. Industrial biorefineries are rapidly increasing both in number as well as in capacity throughout this country, and are thus poised to add significantly to the nation’s industrial goods and energy supplies in coming years. Therefore it is vital for engineering graduates to understand this developing industry and its fundamental concepts, especially those involved in the Agricultural, Biological, Chemical, Environmental, Food, and Process Engineering disciplines. To adequately prepare engineering students for the opportunities presented by biorefining, it is imperative for engineering programs to address this burgeoning industrial segment. Toward this end, this paper will discuss major biorefinery concepts, specific applications, and curriculum modification and incorporation techniques that can be used to achieve these efforts. The trends discussed here and their implications are critical for educators, because in coming years biorefining will be used to simultaneously meet the needs of our society as well as that of environmental stewardship. Introduction As we move into the 21st century, it has become apparent that human societies are over-taxing global resources, and that we are rapidly depleting their finite supplies. This is especially true in the petroleum and petrochemical sectors. Science and technology, however, have progressed to the level that biorenewable materials can now be effectively utilized to produce various manufactured products in their place. Similar to refineries that are used in the petroleum industry, new processing facilities are being designed and constructed to manufacture, from biomass resources, multiple value streams including energy, fuels, chemicals, and various intermediate and finished products. Thus, biomass refineries (known as “biorefineries”) are poised to contribute significantly to the growth and sustainability of the U.S. economy in coming years [1]. Engineering expertise will be required to design, construct, and operate all of the equipment, processes, and facilities for these processing plants. Because biorefineries present many opportunities for the engineering profession, the main objective of this paper is to introduce engineering educators to this new subject so that curricula can be augmented. Toward that end, several essential topics will be discussed, including concepts of biorefineries, the

THE GLOBAL RELEVANCE OF BIO-BASED INDUSTRIES TO ENGINEERING AND TECHNOLOGY EDUCATION Abstract The society in which we live has developed an insatiable demand for energy and material goods. In particular, recent data reveals that the aggressive pursuit of improved standards of living in the highly populated countries of India and China has contributed to increased demand for fossil fuels, which has exacerbated the recent spike in energy costs. Historically, these needs have been met primarily by fossil fuels and other non-renewable raw materials. As environmental concerns grow, however, renewable resources are gaining increased attention. This paper examines the emergence and importance that bio-based industries are increasingly beginning to play. A bio-based enterprise, similar in concept to a traditional refinery or factory, utilizes conversion technologies to produce various products. Bio-based refining and manufacturing operations are rapidly increasing both in number as well as in capacity throughout this country, and are poised to add significantly to the nation’s energy and material supplies in coming years. Therefore, to adequately prepare engineering and technology graduates for the opportunities presented by bio-based industries, it is vital for these graduates to understand this developing industrial segment and its fundamental concepts. Toward this end, this paper will discuss several essential topics, including national production and consumption information for chemicals, fuels, and manufactured products; production data, trends, and growth potential for bio-based industries; similarities between traditional refining and manufacturing industries to bio-based industries; tools essential for success, including quality improvement, management, and business productivity tools; relevance to engineering and technology education; and curriculum modification and incorporation techniques that can be used to achieve these efforts. The trends discussed here and their implications are critical for educators, because in coming years these industries will be used to simultaneously meet the needs of our society as well as that of environmental stewardship. Keywords Biochemicals, Biofuels, Biomass, Bioprocessing, Biopower, Bioproducts, Biorefining, Curriculum Development Introduction Successful manufacturing and industrial enterprises often have a history of adapting to change as markets, and the forces that drive them, dynamically shift over time. The importance of flexibility and openness to change has been emphasized repeatedly if companies are going to succeed and grow, especially when faced with difficult choices of how best to adapt, and inevitably alter business practices, strategies, resources, facilities, locations, or even labor practices. Thus national, and increasingly global, changes can present many opportunities and challenges for both employers and employees.

One of these requirements is that departments demonstrate that they provide students with an understanding of engineering in a broad, societal context. Examination of engineering history can be an essential element to this endeavor, because the development of modern theories and practices have diverse and complex evolutions which are often intimately intertwined with the development of societies themselves. Fluid mechanics is a key field of engineering, whose body of knowledge has had a significant influence on the design and operation of many products and systems over the centuries. Because of this, fluid mechanics coursework is often required for many engineering and technology majors and can, in fact, represent a key component to these programs. Toward these ends, this paper will discuss highlights from the history of fluid mechanics, and will provide several timelines that summarize key scientists, theories, events, equipment and machines. Considering fluid mechanics in this manner can achieve the goal of placing this branch of engineering in an appropriate societal context. It is always a challenge for educators to find useful and interesting material on history; therefore, a summary list of conventional and online resources will also be included. As such, this paper can be used as a resource for both engineering as well as history educators to supplement existing coursework. Keywords Curriculum Development, Engineering, Fluid Mechanics, History, Society, Technology INTRODUCTION As with many fields of modern scientific study, fluid mechanics is rooted in the history of humanity. Over time, as humans adapted and evolved, and their knowledge and skills increased, specific scientific and technological disciplines arose. Many modern conveniences which are now often taken for granted actually originated centuries ago, as have the theoretical foundations upon which they were developed. Throughout its history, fluid mechanics has been a field that has constantly advanced. Inquiry has progressed from trial and error, to formal experimentation, to mathematical theory. As with other engineering fields, it has now reached the point of scientific maturity, with most of the fundamentals clearly understood. As such, it has become a vital component for many engineering curricula. It is therefore a very useful exercise to examine the historical development of this discipline.

This new level of partnership and collaboration between engineering and technology programs promises to be a step in the right direction for society at large. Engineering and technology majors both supplement and complement each other’s knowledge and skills and it is crucial for educators to build bridges of active interaction. This paper takes aim at one specific as well as basic need in teamwork and interdisciplinary projects – ethics and its implications for professional practice. The primary focus here is to promote ethics education among a wider audience that includes industrial technologists. A preliminary study suggests that students majoring in industrial technology degree programs may not have adequate opportunity to formally study and engage in ethical aspects of technology vis-à- vis the practices of the profession. The core curriculum in industrial technology is typically comprised of technical and business courses with significant variation among individual programs. It is reasonable to assume that the ethical issues or dilemmas faced by an industrial technologist would parallel those that of engineers and managers. The authors, both coming with engineering as well as business backgrounds, coupled with significant experience in teaching industrial technology majors, identify a domain of knowledge that would constitute a necessary background in ethics for industrial technologists. Further, this paper also examines various resources for teaching and makes recommendations from a pedagogical point of view. Keywords Curriculum Development, Ethics, Industrial Technology, Society INTRODUCTION The college education of engineers and technologists in the United States in the key areas of construction, manufacturing, communications, and transportation manifests itself in the form of three broad degree programs that can be identified as engineering, engineering technology, and industrial technology. Engineering degree programs have a longer history and even though certain misconceptions regarding the profession of the engineer still do exist among the general public, it is fair to state that the profession is well advertised among high school students and the public at large.

Formaldehyde-based adhesives have been used for several decades due to its convenience. In this paper, we aimed to explore the economics of urea–formaldehyde (UF) adhesives that can be used in wood panels. Two formaldehyde production pathways: metal oxide pathway and silver pathway, were compared in this study. SuperPro Designer v9.5 software was employed to perform the techno-economic analysis (TEA). Key parameters of TEA were calculated and compared of these two pathways, including total capital investment, annual operating cost and product revenues. It was found that the unit production cost of UF adhesive made from metal oxide pathway ($0.86/kg) was less expensive than that from silver pathway ($0.99/kg), but the total capital cost was slightly higher in metal oxide pathway (40 million $) than silver pathway (38 million $). Additionally, sensitivity analysis indicated that final product yield and material costs were the most sensitive factors among all inputs.

According to the importance of vitamin B6 (pyridoxine) as a water-soluble vitamin on the physiological conditions of aquatic animals, the present study aimed to investigate effects of different concentrations of this vitamin in recycle system culture water on the Nile tilapia (Oreochromis niloticus). Treatments including 0 (control), 10, 20, 30, and 40 mg L−1 vitamin B6 were adjusted in triplicate recirculating systems. Each of the experimental tanks (100 L) was stocked 15 fingerling Nile tilapia during 60-day experimental period. According to the findings, weight gain in treatments of 30 and 40 mg L−1 pyridoxine was significantly higher than the other treatments while blood cortisol hormone in the treatment of 40 mg L−1 was significantly highest among the treatments. In addition, mid-intestine trypsin activity in the treatment of 40 mg L−1 was significantly higher than the other treatments. The histological analysis of the intestine showed that the number of mucus-secreting cells significantly decreased in treatments of 30 and 40 mg L−1. Our findings here suggest that pyridoxine can possibly be absorbed by the Nile tilapia’s body through culture water and it seems 20–30 mg L−1 pyridoxine in the culture water is the optimal concentration for the Nile tilapia juveniles in recycle system culture.

Traditional formaldehyde-based adhesives still play a crucial role in the current market, despite increasing environmental concerns resulting from their production. The purpose of this paper was to evaluate the environmental impacts of formaldehyde-based adhesives, urea-formaldehyde (UF) adhesive and phenol-formaldehyde (PF) adhesives, mainly used in wood products. In this study, a functional unit of 1 kg adhesive was used. GaBi 6 software was employed to perform the life cycle assessment (LCA). Several key parameters for life cycle analysis were analyzed, such as global warming potential, acidification potential, eutrophication potential, and human health. As a result, the greenhouse gas emissions ranged from 2.04 kg CO2-eq./kg of UF adhesive to 2.88 kg CO2-eq./kg of PF adhesive. In terms of the overall environmental impacts, it was found that UF adhesive had a nearly 50% higher life cycle impact than PF adhesive. Comparing the energy consumption used in UF and PF adhesives, UF adhesive was much lower than PF adhesive. Transportation distance was determined to be a sensitive parameter with respect to global warming potential for formaldehyde-based adhesive.

This study is a comparative evaluation of three approaches to biofuel production from energy crops including biogas, bioethanol and biodiesel to ascertain which one is the most effective and more energy-efficient than the others. Moreover, the potential of biofuel production from the best option was studied. For this purpose, biogas generation from corn silage, bioethanol generation from corn, and biodiesel production from peanuts in Iran (as a case study) were studied. The results revealed that 10,683.36 m3 of biogas, 2.53 m3 of bioethanol and 0.70 m3 of biodiesel could be produced per each hectare of energy crops. The total greenhouse gas emissions for each MJ energy generation of biogas, bioethanol and biodiesel were 0.01, 0.04 and 0.03 kgCO2eq, respectively. Accordingly, the total annual biogas potential from corn silage (as the best option) in Iran is 3953.74 million m3, which is equivalent to 1515.94 million barrels of oil.

The stimulation of renewable fuel production is related to the environmental issues resulting from the extraction and utilization of fossil fuels. Although corn-based ethanol is one of the leading renewable fuels and promises to mitigate these environmental impacts, it generates large volumes of wastewater with high concentrations of organic material (CODcr > 30,000 mg/L) and low pH (3.5–4.5), which leads to serious environmental concerns. A common method of treatment of distillery wastewater is the Dry Distilled Grain Soluble (DDGS) process, which separates liquid and solid fractions; however, a disadvantage of this process is its high energy consumption. Other commonly implemented methods are often costly and not environmentally safe. To minimize these problems, a flocculation process can be applied as a potential lower energy consumption process utilizing bioflocculants, which have been proven harmless to the environment. Therefore, the main goal of this study was to analyze the economic and environmental impacts of using bioflocculants instead of evaporation process in a corn-based ethanol plant. The procedures were evaluated by analyzing the Life Cycle Assessment (LCA) and Techno-Economic Analysis (TEA). From the results, it can be seen that the flocculation system can be an alternative process for effectively minimizing energy consumption during the production of DDGS, Distilled Wet Grains with Solubles (DWGS), and corn oil. The flocculation process achieved a significantly (28%) lower utility cost when compared to the conventional system. However, the overall fixed costs and annual operating costs for the flocculation system were higher than those of the conventional system. Additionally, both processes resulted in negative profit and a sensitivity analysis showed that the feedstocks cost substantially impacted the DDGS, DWGS, and corn oil production costs. Related to environmental aspects, the LCA results showed that the flocculation process achieved the lowest Global Warming Potential (GWP) of the several electricity supply technologies analyzed and presented a significant reduction in CO2 equivalent emissions when compared to a conventional system. The flocculation process resulted in approximately 57% lower greenhouse gas emissions.

Technoeconomic analyses using established tools such as SuperPro Designer® require a level of detail that is typically unavailable at the early stage of process evaluation. To facilitate this, members of our group previously created a spreadsheet-based process modeling and technoeconomic platform explicitly aimed at joint fermentative‒catalytic biorefinery processes. In this work, we detail the reorganization and expansion of this model—ESTEA2 (Early State Technoeconomic Analysis, version 2), including detailed design and cost calculations for new unit operations. Furthermore, we describe ESTEA2 validation using ethanol and sorbic acid process. The results were compared with estimates from the literature, SuperPro Designer® (Version 8.5, Intelligen Inc., Scotch Plains, NJ, 2013), and other third-party process models. ESTEA2 can perform a technoeconomic analysis for a joint fermentative‒catalytic process with just 12 user-supplied inputs, which, when modeled in SuperPro Designer®, required approximately eight additional inputs such as equipment design configurations. With a reduced amount of user information, ESTEA2 provides results similar to those in the literature, and more sophisticated models (ca. 7%–11% different).

Due to increasing environmental concerns about petroleum-based products, the replacement of petro-products has attracted much attention in recent years. The purpose of this paper was to evaluate the potential environmental impacts of glycerol-based structural bio-adhesive produced through the reversible addition-fragmentation chain transfer polymerization process. In this study, two pathways of glycerol production were considered in this cradle-to-gate life cycle assessment: bio-glycerol produced from biodiesel production plant and petroleum-based glycerol derived from petroleum refineries. Several impact categories were analyzed including global warming potential, acidification potential, eutrophication potential, and human health effects (both cancer and non-cancer). The impact of different allocation methods (energy content, mass value, and economic value) was also explored in this study. Our results showed that bio-glycerol-based structural adhesive had a lower environmental impact in general compared to petro-glycerol-based structural adhesive. Higher environmental impacts throughout the structural bio-adhesive life cycle were observed by adopting the energy allocation method. The key factors that influence the global warming potential were electricity sources and the product yield. This LCA study provides useful information for developing sustainable biomaterials and processes. It is recommended to further explore the potential approaches to reduce the carbon intensity and eutrophication potential in the RAFT polymerization process as it is identified as the hotspot in the structural bio-adhesive production process.
